In December 1983, the United States Congress directed the Federal Communications Commission (FCC) to establish a plan to ensure that the communications needs of state and local public safety authorities would be met. The Commission issued a Notice of Inquiry on March 7, 1984 and over 300 comments from the public safety community and other interested parties were evaluated by the FCC staff.
These comments formed the basis for a Staff Report issued by the Commission's Private Radio Bureau on August 1, 1985. This report suggested various methods of meeting the communications needs of public safety. One option included the allocation of additional frequencies at 821-825 MHZ and 866-870 MHZ.
The Commission issued an allocation order on September 19, 1986. Six megahertz of spectrum were selected in the 821-824 MHZ and 866-869 MHZ bands since they were adjacent to frequencies already being used for public safety purposes. However, while the Commission made this allocation for this additional 6 MHZ of spectrum for public safety use nationwide, they also recognized the necessity of developing a National Plan to promote interoperability among public safety providers and to insure an efficient use of the newly allocated spectrum.
Recognizing the importance of public safety participation in the development of the National Plan, the FCC established the National Public Safety Planning Advisory Committee (NPSPAC) in December, 1986. With an open membership, NPSPAC provided the opportunity for the public safety community and other interested members of the public to participate in an overall spectrum management approach. The Commission charged NPSPAC with the following tasks: (1) identify communications requirements of public safety agencies; (2) develop a scheme for efficient use of the new frequencies; (3) develop a scheme to increase the utility of existing public safety frequencies; (4) recommend the manner in which new technologies can be applied to the public safety frequencies; and (5) recommend guidelines to ensure compliance with the National Plan.
NPSPAC submitted its Initial Report to the Commission in March, 1987. On May 15, 1987, the Commission issued a Notice of Proposed Rule Making which proposed policies and rules for the National Plan. NPSPAC issued its Final Report in September, 1987. On December 18, 1987, the Commission released a report and order regarding the development and implementation of a Public Safety National Plan: General Docket No. 87-112.
The National Plan consists of guidelines for the development of regional plans. The National Plan reflects the FCC's regulatory objective of maximizing spectrum efficiency and ensuring sufficient flexibility to accommodate specific communications requirements in different areas of the United States. Thus the United States was divided into Regions, primarily along state boundaries. A few large metropolitan areas were designated as independent Planning Regions.
Prior to the Report and Order, NPSPAC's Final Report had recommended a total of fifty-four (54) Planning Regions. However, when the Report and Order was released, the Commission had established only forty-eight (48) Planning Regions. A Petition for Limited Reconsideration was filed by NPSPAC on February 12, 1988, asking that additional planning regions be established due to densely populated metropolitan areas which were regions in themselves. The Commission granted this Petition and established fifty-five (55) regions with Arizona as Region 3. The National Plan will serve as an umbrella under which regional plans such as this can be developed and implemented.
The National Plan provides guidelines for the development of regional plans, with as much regional self governing as possible, to ensure that the needs of all eligibles are considered in the planning process.
The state of Arizona encompasses almost 114,000 square miles and makes up Region 3. Much of the state is sparsely populated Federal and Native American Reservation land. There are two major population centers, Phoenix and Tucson. The State currently has over 3.5 million residents with population projections indicating an increase to 6.5 million people by the year 2000.
Geographically, Arizona is a complex mixture of environments varying from desert scrub plants near sea level to barren mountain peaks at over 12,670 feet elevation. An example of the extreme desert to mountain change occurs in the Tucson area where the Sonoran Desert basin changes to a pine forest in the Coronado National Forest, an almost 7000 foot change occurring in about 15 miles. Besides the Grand Canyon, another major geographic feature is the Mogollon Rim, a 200 mile long geographic barrier which separates the northern and southern portions of the State. The top of the Rim plateau contains the world's largest standing Ponderosa pine forest. The high mountains provide both the best and worst of radio communications and the ensuing interference and spectrum planning problems.
This plan has been developed by a representative group of Public Safety Services eligible for licensing in the 6 MHZ of the 800 MHZ spectrum. Authority for the Regional Planning Committee to carry out its assigned tasks is derived from the Federal Communications Commission (FCC Report and Order, Docket 87-112).
3.1 Regional Planning Committee
A Convener was selected and public notification pursuant to the National Plan was initiated. Since the state of Arizona has two large populated metropolitan centers and the majority of the state is rural areas, three (3) public meetings were held in order to accommodate the rural areas. See Appendix III for the meeting minutes and names of those in attendance.
The membership of the Arizona Regional Planning Committee is open to representatives from all eligible user groups pursuant to FCC Report and Order, Docket 87-112, Section IV, Subsection B, Paragraph 46. Interested parties became participants in the formation of the Regional Planning Committee and represent both the Public Safety and Special Emergency Radio Services. A total of 105 individuals have participated in the Plan's developmental process. Appendix I lists names, organizational affiliations, and mailing addresses of all participants in the Regional Planning Committee formation.
Prior to working on the plan, the working committee sent two questionnaires to all Public Safety and Special Emergency Radio Service users for input concerning present and future communications needs (See Appendix IV for results). After compiling the received data from responding agencies, the Regional Planning Committee drafted the Plan.
A working committee was established to facilitate the development of the Regional Plan. Their main function was to receive input from local, state and federal representatives, as well as vendors and suppliers to be used in the formation of the Regional Plan. Members of this committee are as follows:

Prior to submitting the plan for FCC approval, an announcement was made that a draft of the Plan was available for review, and copies were sent to any requesting party. All adjacent regions (Region 5 - Southern California, Region 7 - Colorado, Region 27 - Nevada, Region 29 - New Mexico, and Region 41 - Utah) received copies for review and comments. (See Appendix VI for concurrence)
All comments were to be received by February 1, 1991. A public meeting was held on February 7, 1991 @0930 hrs at the City of Glendale Council Chambers Building, as a means for those interested parties to make their comments known before the Working Committee. Following receipt of all comments, the Working Committee made modifications to the Plan by the opinion of the majority. Copies of the modified sections of the Plan were sent to those parties who had submitted comments. Upon approval of the changes, the final plan was formulated.
Upon FCC approval of this plan, a Regional Review Committee will be established for the review of new applications and for conducting an annual system implementation review. Since modifications to the Plan may be necessary because of changing requirements, the committee will also recommend changes and/or modifications of the Regional Plan to be submitted to the FCC. The committee will also provide a mechanism for resolution of inter- and intra- regional disputes and for exercising general oversight of the Plan.
The Arizona Regional Review Committee (ARRC) shall be comprised of eleven members with no more than one committee member from a single political jurisdiction. Nominations to the committee shall be made as part of an open, general meeting.
Semi-annual open, public meetings shall be held concurrent with Arizona APCO chapter meetings. Each attending political jurisdiction shall be apportioned one vote at each meeting. Designated representatives and alternates shall be identified prior to the meetings.
Voting on vacancies shall take place at the general meeting of the ARRC after publication of all nominations to the entire APCO chapter membership. Members to this committee must be elected by a majority vote of all designated representatives present at the semi-annual meeting, as per Robert's Rules of order, and who are current employees of an Arizona political jurisdiction. The chairperson of this committee shall be chosen by the committee.
There shall be no time limit for serving on the ARRC, but a member may be removed from this Committee by resignation or by a vote of the quorum of an open, general meeting. Such removal may take place only after a thirty day written notice has been made to the entire authorized voting representatives.
No changes, modifications, or amendments can be made to the approved Plan unless agreed to by at least a two-thirds majority of the quorum of the ARRC members.
No change in a position on the priority list for assignment of a frequency in either the 800 MHz spectrum or in reallocation of lower frequencies that may be given up to receive 800 MHz assignments can be made unless approved by at least a two-thirds majority of the ARRC.
Minutes of all meetings of the ARRC must be taken and mailed to the appropriate agencies.
This Plan, when approved and implemented, will ensure the best possible use of this new portion of the spectrum and will also ensure an orderly transition from existing frequencies/systems to this new portion of the spectrum. It will also serve as a guide in the reassignment of vacated channels, and provide, through the Regional Review Committee, an ongoing method of ensuring fair and equitable recommendations of channels and usage to all Public Safety Services and users. Resolution of any arising conflict is left to the judgement of the Commission.
4.0 COMMUNICATIONS REQUIREMENTS - REGIONAL INTEROPERABILITY
This part of the Arizona Regional Plan deals with the requirement for coordinated communications between various jurisdictions and functional entities within the Region. The intent is to ensure compatibility in the assignment of frequencies, especially calling and interoperability channels. The purpose of this plan is not to replace existing intercommunications plans or channels, but to supplement them at 800 MHZ with a more detailed plan. In fact, the Regional Plan encourages continued use of VHF and UHF intercommunications presently in use for Police and Fire, including 155.475 MHZ, 460.375 MHZ, and 154.280 MHZ. The plan also encourages cross patching these channels to the 800 MHZ Common Calling Channels, and others as appropriate, at the dispatch console level within regional operating subsystems.
4.2 Regional Calling and Interoperability Channels Authority
The Federal Communications Commission (FCC), in Docket 87-112, Sec. IV.C.50-52, released Dec. 18, 1987, mandated the use of a single, conventional, common-calling channel and four (4) tactical channels on a nationwide basis in the new 800 MHZ Public Safety allocations. The FCC also strongly recommended the use of CTCSS tone squelch nationally on a frequency of 156.7 Hz.
The Arizona Regional Planning Committee has reviewed and implemented the five (5) national channels, and added one (1) additional 800 MHZ channel for interoperability strictly within the Arizona Region. The Arizona Plan also adopts the use of 156.7 Hz tone squelch as mandatory on all voice radio systems on the common calling and interoperability channels.
Primary eligible users include Police, Fire, Local Govt., Highway Maintenance, Forestry Conservation, and providers of Basic and Advanced Life Support Services in Special Emergency Services, as defined in the FCC Rules and Regulations, and licensed to use the spectrum. These users are eligible to operate base stations on the five (5) National and two (2) Statewide interoperability channels. In addition, Federal agencies may become eligibles through the use of public safety agreements, whereby a licensee may permit federal use of a non-federal communications system. Such use, other than the five common calling channels is to be in full compliance with the FCC's requirements for federal government use on state and local government frequencies (Title 47 CFR, Sec. 2.103).
Also, other eligibles such as school buses, volunteer emergency corps, Red Cross, Radio Amateur Civil Emergency Services (RACES), Amateur Radio Emergency Services (ARES), Salvation Army, etc., under the National Plan may also participate on a secondary basis in the support of the preservation of life and property during an emergency.
All interoperability channel licensees for Mobile Relay (FB2), or Fixed Stations (FB) shall be obtained by and in the name of the entity authorized by the Arizona Regional Review Committee. Other base radios shall be licensed in the name of the applicant agency. In accordance with FCC Report and Order General Docket 87-112, vehicular, portable, and aircraft stations using either the five National channels or the Statewide interoperability channel (Channel 6) may operate without further FCC authorization. However, the prospective vehicular/portable/aircraft user must comply with 4.5.4 of this section.
4.5 Allocated Common Calling/Interoperability Channels
The use and allocation of the calling and interoperability channels is broken down as follows:
Channel 1 (821/866.0125 MHZ) - National Public Safety Calling and Rural Tactical Operations Interoperability.
Channel 2 (821/866.5125 MHZ) - Primary Fire and Emergency Medical Service In Maricopa County; Secondary in Pima County.
Channel 3 (822/867.0125 MHZ) - Primary Police in Maricopa County; Secondary in Pima County.
Channel 4 (822/867.5125 MHZ) - Primary Fire and Emergency Medical Service in Pima County; Secondary in Maricopa County; Federal Govt.
Channel 5 (823/868.0125 MHZ) - Primary Police in Pima County; Secondary in Maricopa County; Federal Govt.
Channel 6 (821/866.0500 MHZ) - Primary Statewide for all Other Public Safety, including Highway/Forestry/Local Govt./Search & Rescue.
Although primary and secondary usage is defined above, this is not to preclude use by all other eligibles when appropriate in coordinated operations. (See 4.3)
4.5.1 Common Calling Channel Monitoring Requirements
All new portable/mobile radios granted license authorizations in the 821-824 MHZ and 866-869 MHZ bands, as well as all replacement equipment in the 806-821 MHZ and 851-866 MHZ bands, shall be capable of and equipped to operate on Channels 1 - 6 calling and tactical frequencies in the conventional mode of operation. In addition, each portable/mobile radio shall have the repeater "talk-around" channel on Channel 1 (National Calling Channel) and on their primary and secondary service tactical channels. Also, a Public Safety eligible receiving a new 800 MHZ license is required to be able to monitor and communicate in the repeater and "talk-around" modes at their primary communications site.
The largest geographic Public Safety 800 MHZ new system licensee in a geographic area may be required to place in operation, a Channel 1 calling channel repeater at one or more of their existing repeater sites. If notification is made to a prospective licensee as a condition of system plan acceptance by ARRC and the FCC, the station shall be placed in service at the same time with the rest of the authorized system. A suitable Calling Channel funding plan shall be submitted as part of the authorization request.
4.5.2 Tactical Channel Requirements
4.5.2.1 Monitoring Requirements
Each new licensee in the 800 MHZ spectrum shall also have a base station radio at their primary station site, as a minimum requirement, capable of monitoring and operating on the primary and secondary tactical channels in their area, for which they are eligible service providers. This base station radio shall include frequencies for both simplex and repeater control.
4.5.2.2 Repeater Establishment
No permanent high power repeaters shall be established on any of the tactical channels. However, low power (<20 watts ERP) transportable repeaters may be employed by any eligible service agency for establishing emergency communications over a wider area than simplex communications would allow. Such a repeater shall be turned off and removed as soon as practical after the event has passed. At no time will a tactical repeater be allowed to operate for more than a 30 day continuous period.
4.5.2.3 Voice Security/Privacy/Scrambling Equipment
Voice scrambling or encryption is NOT ALLOWED on the Common Calling Channel, except in rural areas, where the calling channel is also used for tactical operations. In rural areas, each licensee is still required to monitor the calling channel in CLEAR mode, regardless of voice encryption.
Voice scrambling or encryption IS allowed on the other voice tactical channels, either unit to unit, unit to base, or through a temporary repeater if all users of the temporary repeater also have access to the CLEAR mode, or the same encryption scrambling standard as required.
Each prospective licensee shall include a standard signed statement form with their request for authorization, acknowledging they have read and are familiar with the Arizona Regional Plan and agree to abide by its conditions, especially insofar as the Common Calling and Tactical Channel operational requirements.
4.5.4 Priority Levels of Utilization
The established priority use levels for the six (6) calling/tactical channels are described below. When a higher priority of use is required, all lower priority use must cease in ANY area where interference could occur.
The four priority levels are:
PRIORITY 1: Disaster and extreme emergency operations of large scale, involving imminent safety of lives, for mutual aid and interagency communications.
PRIORITY 2: Emergency or urgent operations involving imminent safety of life or property.
PRIORITY 3: Special event control activities, generally of a preplanned nature, and generally involving joint participation of two or more agencies.
PRIORITY 4: Drill, maintenance, and test exercise of a civil defense or disaster nature.
4.5.5 Language and Radio Codes Standards
All communications on the Calling Channel will be conducted in "CLEAR TEXT", using the ENGLISH language, unless use of another language is clearly necessary to carry out emergency communications.
4.6 Federal Govt. Communications Interface Requirements
Federal Govt. agencies, operating within the borders of the Arizona region, may access the Common Calling and Tactical Channels for the purpose of coordinating with and communicating with Public Safety eligibles. Federal agencies are exempt from the monitoring requirements set forth in Sec 4.2. However, their use of the Common Calling and Tactical Channels shall otherwise be in complete conformance with the Regional Plan.
Before a federal agency is certified eligible to access the Common Calling and Tactical Channels, there shall be established a formal agreement with the Public Safety eligible with whom they desire to have communications. This agreement shall be on the standard ARRC form. Each agreement shall be mailed to the ARRC for review and to be placed on file with the committee.
4.7 Public Switched Telephone Network
The use of automatic or operator-assisted connection on the Common Calling and Tactical Channels to the public switched telephone network is strictly PROHIBITED.
4.8 Amateur Radio Intercommunications
It is the intent of the Arizona Regional Plan to encourage participation of the Amateur Radio community in public safety communications relating to emergency or disaster communications.
The following intercommunications of public safety radio communications systems are encouraged in emergency/disaster situations:
4.8 Amateur Radio Intercommunications
All Amateur/Public Safety communications shall continue to comply with applicable FCC Rules and Regulations, and rules and plans of the affected amateur group.
It is strongly recommended that each Public Safety entity have an agreement in place with volunteer amateur groups, defining what level of intercommunications will be allowed and provided during an emergency situation. This plan should be filed with the ARRC coordinator for approval.
Operation of radio equipment on the six (6) Common Calling and Tactical Channels is permitted, provided power is limited to 3 watts ERP and conforms to all applicable FCC Rules and regulations.
Existing radio equipment that is currently operating in 806/866 MHZ band and was in the agency's possession or ordered on/or before September 7, 1988 may be used with notification to the ARRC. To operate on the five (5) National Mutual Aid Channels, the deviation is to be +/- 4.0 KHZ maximum.
4.11 Unit Identifiers/Automatic Station ID
Units operating on the Mutual Aid Channels are to include their agency name in their unit identification. (Example: Maricopa County, Mesa PD Unit 2 Adam 01) Automatic Station Identifiers usage is encouraged, but is not to replace the voice identification requirement.
5.0 COMMUNICATIONS REQUIREMENTS-INTERREGIONAL INTEROPERABILITY
This portion of the Arizona Regional Plan deals with the requirement for coordinated communications between the Arizona Region, and adjacent regions in the Southwest. This includes the Southern California Region, Nevada Region, Utah Region, Colorado Region, New Mexico Region, and the Nation of Mexico. The purpose is to insure compatibility in the assignment of frequencies, especially Common Calling and Tactical Channels. This plan does not replace any current VHF or UHF common channels in use by eligible agencies along the borders, but supplements them through designation of new Common Calling and Tactical Channels at 800 MHZ.
5.2 Interregional Calling and Tactical Channels; Authority:
The Federal Communications Commission (FCC) in General Docket 87-112, released Dec. 18, 1987, mandated the coordination of each authorized region's activities with adjacent regions.(IV.C.50-52)
The Arizona Regional Planning Committee has implemented a set of rules dictating interregional compatibility. These rules were made after contacting all adjacent regions to determine if there was any potential conflict with their plans. However, since some of the adjacent Region Plans have not yet been approved by the Commission, future changes may be required to ensure long-term compatibility.
5.3 Southern California Region Compatibility:
The common western border along the Colorado River with California, including San Bernadino, Riverside, and Imperial counties, is the area most likely to run into conflict both in operating frequency assignment, and in interoperability channel use. Southern California has previously asked for Arizona approval of their plan. This approval has been granted, after reviewing their plan. As a result, Arizona will not assign 823/868.5125 MHZ or 823/868.9875 MHZ to any agency located along the California border to avoid potential interference with their Channel 6 (Law) and Channel 7 (Fire/EMS) interoperability channels.
In a reciprocal manner, California has been asked not to assign Arizona Region interoperability Channel 6 (821/866.0500 MHZ) along the Colorado River.
Arizona licensees are encouraged to utilize the nationwide five common calling/interoperability channels to intercommunicate with California licensees when joint response is required along the Colorado River. Since this entire area is considered "Rural" in the Arizona Plan, any of the interoperability channels may be utilized for any service function with California.
5.4 Other Adjacent Region Compatibility:
Arizona rural licensees are likewise encouraged to utilize the five nationwide Common Calling/Tactical Channels along the border with any other region (Nevada, Utah, Colorado, New Mexico) as local conditions require. Any service use of the interoperability channels is permitted to achieve joint communications with other regional licensees. This plan may be amended from time to time as other regional plans continue to be developed. (Refer to Appendix V for letters of concurrence from adjacent regions.)
5.5 Communications with Mexico:
All interoperability frequencies are assumed to be usable and assignable to the Mexican Border as long as there is a mutual agreement on use within the 110 Km of the border. However, this portion of the plan is subject to automatic change depending upon FCC regulation and treaty with Mexico.
Governmental police eligibles may communicate with officials from Mexico along the border in the event of an emergency or disaster. This should be done on the Common Calling and interoperability channels, and only in conformance with Part 90.19c of the FCC Rules and Regulations. Sonoran authorities have been notified as to the Arizona Regional Plan for use of these frequencies.
Any request for frequencies between 821-824 and 866-869 MHZ to be used for public safety operations (as described in Part 90 of the FCC Rules and Regulations) must be submitted to the Arizona Regional Review Committee (ARRC) for review.
SEND APPLICATION TO:
If adequate spectrum is available, the ARRC shall review the application to determine its compliance with the Regional Plan as indicated below. If there is inadequate spectrum or the Committee anticipates a shortage, the established evaluation procedure shall be instituted. This procedure, "Evaluation Criteria", is outlined in Section 7.6.
Additionally, shared multi-agency systems will have priority consideration in accordance with the FCC Report and Order, Paragraph 37.
Also, in accordance with Paragraph 13 of the Report and Order, when it is not possible to grant requests for assignments in the new 800 MHZ spectrum to everyone who is eligible, the highest priority must be given to those organizations most fundamentally involved in protection of lives and property.
If approved by the ARRC, the request for frequencies will be returned to the applicant to be forwarded to the Associated Public Safety Communications Officers (APCO) for frequency coordination. If not approved by the ARRC, the request will be returned to the applicant for revision and correction before being resubmitted to the Committee for further consideration.
The request shall contain information to justify the frequencies requested and shall demonstrate compliance with the Arizona Regional Plan. As a minimum, the request shall consist of the following:
Applicants for new frequencies in public safety allocations below 800 MHZ may also apply to the ARRC. Using the criteria described in Section 8.0 of the Plan, the ARRC will assign the appropriate point total to such applications and add them in order of points to any waiting list for relinquished frequencies.
7.0 APPLICATION EVALUATION PROCEDURES
The Arizona Regional Review Committee will review and evaluate each request based on the sufficiency of the information required in the following:
A brief statement of the intended use of the requested frequencies and how they will be integrated into the existing emergency and non-emergency operations will be required. The efficiency of 800 MHZ frequencies depends greatly upon the design and programming of the system itself to assist all public safety users in making all systems operate in an efficient manner. This is the reason this area is being included for review. Specific criteria regarding system parameters are in the section, "System Technical Design Requirements." (See 9.0 )
Below are the different requirements for the system design. Additional detail follows, including sample calculations.
A. Listing of System Coverage and Service Area.
The applicant's commitment to implement the system ensures maintaining the efficient utilization of these 800 MHZ frequencies. The funding statement, which will be a resolution from the applicant's governing body, will include the method by which the system will be funded.
The applicant will be requested to furnish a schedule detailing the time period required to implement the proposed communication system, from funding through turn-on and final acceptance. Also indicate if "slow growth" is required.
All agencies applying for frequencies in the 800 MHZ bands shall submit a letter of intent from the agency's Chief Administrative Officer verifying a fiscal and engineering commitment to the implementation and construction of a radio system within the parameters listed below:
The Regional Review Committee anticipates that not all agencies or jurisdictions with allotted channels in the Plan will construct systems. The Regional Review Committee also recognizes that some agencies or jurisdictions may require more channels than are allotted in the Plan. The Plan envisions and the Regional Review Committee insists on a good faith showing of the intent from all agencies and jurisdictions with allotted channels. Therefore, channels will be considered available for allocation if licensing has not been initiated or specific plans have not been filed with the Regional Review Committee. The Plan has been in effect since September, 1991. The Regional Review Committee considers this sufficient time for agencies and jurisdictions to have developed a long range plan for use of these channels and to have provided notification to the Regional Review Committee.
7.4 Justify the Number of Channels
The following criteria shall be used to justify the number of channels requested:
7.5 Existing Frequency Statement
The applicant will provide an explanation of how existing frequencies will be used by the applicant and a listing of the frequencies (give backs) to be released for re-use. Time frames for the release of frequencies for reassignment should be included in the implementation schedule submitted with the request.
Commitments to release channels shall become part of the Regional Plan and released channels shall be assigned to qualified agencies in accordance with the National/Regional Plan commitments. Letters of commitment must be provided by the applicant giving up the frequencies to the ARRC. Reassignment to give back frequencies will be made part of the plan.
The criteria, when instituted, incorporates a filing window concept which will provide for the evaluation of all applications for available spectrum within a set time period. The evaluation is a sequence of events that will be followed in the allocation of the six megahertz of 800 MHZ spectrum. This process follows the guidelines established under the National Plan.
The allocation is placed in the frequency pool. If frequencies are available in the pool (a second iteration of the evaluation could occur if all frequencies are not allocated on the first iteration), a window opening announcement is made. The first window period will be thirty days with late applications rejected. The second window will open upon completion of processing of applications received in the first window period. Applications are received and reviewed during the window period. The evaluation will result in the award of a score for each application. That score is the total of the points awarded in seven categories, with a maximum possible score of 1000 points.
The six categories are as follows:
Points are totaled for each application and the applications are prioritized by the Arizona Regional Review Committee. The frequency pool is allocated and the Arizona Regional Plan is updated to reflect the frequency assignments.
System implementation is monitored by the Arizona Regional Review Committee which determines if progress is being made. If progress is not made, the licensee is warned of the consequences of his lack of progress. If continued monitoring indicates that sufficient progress is still not being made, the Federal Communications Commission (FCC) may be notified of the non-compliance and the licensee will be notified by the FCC of pending action that may result in withdrawal of their license. The notified licensee can appeal this action or can allow the license to be withdrawn. If the allocated frequencies are withdrawn, they are added back to the frequency pool.
Throughout the frequency allocation process, applicants are given the opportunity to appeal decisions which have caused rejection of their application. The appeal process has two levels: the Arizona Regional Review Committee (ARRC) and the Federal Communications Commission (FCC). An applicant who decides to appeal a rejection should file the appeal with the ARRC within 45 days from notification of rejection. If the applicant is not satisfied with the ARRC's final decision based on the appeal, the applicant may file an appeal with the FCC. The FCC's decision will be final and binding upon all parties.

The Arizona Regional Plan encourages the surrendering of existing frequencies in the VHF and low UHF range by applicants for the 800 MHZ spectrum. The ARRC will prioritize applicants for surrendered VHF and low UHF frequencies. This committee will then recommend any available frequency for the use of the highest priority applicant. This recommendation must be consistent with the frequency's normal service category, the applicant's eligibility within that service, and the technical way in which the frequency will be used. The ARRC will recommend approval of the license application by the appropriate frequency coordinator.
The ARRC will evaluate applications based upon the criteria established in Part 47 CFR, Part 22.504 and Part 90 of the Federal Communications Commission Rules and Regulations.
8.1 General Re-assignment Philosophy
Because of the demographic and geographic makeup of Arizona, the Arizona Region Plan encourages the following general frequency usage:
The Arizona Regional Plan establishes a system for assigning points in order to prioritize applications for reassignment of surrendered frequencies. A total of 575 points is possible. The components of the point total are dependent upon:
Criterion Methodology Max Points Max
Antenna Height Above Optimum HAAT divided by 50 pts.
Average Terrain (HAAT) design HAAT times 50.
(See note 1)
Effective Radiated Optimum ERP divided by 50 pts.
Power (ERP) design ERP times 50.
(See note 2)
Coverage Area of Operations 100 pts.
divided by Reliable
Service Area times 100.
(See note 3)
Radiation Pattern Area of Operations 75 pts.
sector width, in degrees
divided by the total sector

9.0 SYSTEM TECHNICAL DESIGN REQUIREMENTS
9.1 Coverage Limitation - Antenna Height and Power
System coverage or service area is limited to geographical boundaries in order to maintain maximum frequency reuse within the region. The intent is to restrict the area of radio coverage to the actual jurisdictional boundaries. Agencies requesting new or additional channels will have their proposed system design evaluated by the Arizona Regional Review Committee. Any agency requesting a transmitter location not centrally located within its jurisdiction must include in their request adequate justification for such placement. Transmitter placement and antenna radiation patterns must be chosen to maintain radio system coverage within the jurisdictional boundaries of the entity making the application.
Agencies with service areas outside their political boundaries may request extended system coverage. Such requests for extended coverage must be accompanied by written justification, including an Intergovernmental Agreement covering all involved parties.
Extended coverage systems will not be authorized unless approved by the Arizona Regional Review Committee. Favorable consideration will be given to those extended coverage systems which are made available for use by eligibles other than the licensee.
A licensee may apply to utilize one of their authorized base/mobile frequencies as a point-to-point channel pair. This usage must be within the licensee's defined service area, or extended service area, if authorized. Channel loading requirements still apply to a channel used for point-to-point communications.
9.2 Definition of Service Area
Radio System Coverage for "Service Area" is defined as the boundary where predicted signal strength falls to 41 dBu. System parameters must be modified to make sure that the location where the actual service strength falls to 41 dBu is located near the actual service area boundaries, and the signal strength must fall to 40 dBu or below at a point three (3) miles beyond this point.
9.3 Calculation of Service Area
Three factors must be known to determine service area: (1) the strength of the received signal, i.e., "received signal strength," (2) antenna height above average terrain (HAAT), and (3) the effective radiated power (ERP). Received signal strength has been defined (41dBu), leaving the other two factors that can be modified to achieve the desired coverage. The resulting calculations determine the radius of coverage from the transmitting site. An example of these calculations is shown in the appendix.
It will be permissible for agencies requesting system authorization to determine the distance to the 41 dBu boundary on a radial-by-radial basis with a minimum of eight equally spaced radials at 45 degree intervals, beginning at true North, and plot the service area boundary based on these points. This plot should be submitted with the request for frequencies to show that radio coverage area outside the agencies' political boundary is being kept to a minimum. In any case, a minimum antenna height of 100 feet above ground elevation will be necessary to provide clearance with roof lines and tree tops. Any agency with its service area radius of eight (8) miles - regardless of the size of its jurisdiction - providing interference protection for existing co-channel and adjacent channel systems is sufficient.
9.4 Responsibility for Calculations
It will be the responsibility of the requesting agency to calculate the proposed radio coverage service area and to validate the accuracy of the calculation. It is the requesting agency's responsibility to provide accurate system parameters and determine "Height Above Average Terrain" radials as specified in 90.309(a)(4) of the FCC's Rules and Regulations.
9.5 Proposed Service Area Exhibit
An agency shall provide, along with its request for frequencies, an exhibit showing the calculated radio coverage service area and the agency's jurisdictional boundaries as well as adjacent city, town, county and state boundaries. The boundaries must be drawn to scale on a 1:250,000 USGS map or suitable scaled computer drawn maps, with a title block including the name of the requesting agency, and the following transmitter information: antenna height, height above average terrain, effective radiated power, latitude, longitude, ground elevation of each transmitting site, and the distance to the service area boundary in miles, as calculated and indicated on the map.
9.6 Control Station (Limit on Effective Radiated Power)
Control/Base stations shall conform to the radio service area 41 dBu boundary requirement.
Careful adherence to the system technical design requirements of this Plan will allow for maximum co-channel usage within this region. Because of the close proximity of adjacent channel frequencies, planning for adjacent channels must be similar to the considerations required for co-channel system design.
An agency requesting frequencies that have been previously licensed within this region or an adjacent region must demonstrate that the proposed system will provide, an "existing to proposed" signal margin of at least 25 dB at the closest point to the service area boundary of the existing system.
As part of this plan, distances between transmitter for co-channel reuse will not be held to seventy (70) mile separation. Separation of co-channel transmitters will be determined by the coverage needs of the applicant, natural barriers for separation, antenna patterning and limited ERP's where possible. System tests and/or propagation studies may be provided to establish minimum distances for separation.
Proposed systems must also be designed for minimum interference operation with adjacent channel licensees. The method of determination is identical to that of co-channel design as detailed elsewhere in this Plan, with the exception of the existing to proposed signal margin criteria. In the case of adjacent channel systems, this margin will be reduced to 15 dBu, except that if all adjacent agencies are meeting the narrowband 12.5 KHZ emission mask, no adjacent channel protection will be required. All other calculations will remain the same.
It should be noted that the FCC has adopted technical standards for transmitters which will reduce adjacent channel interference and permit closer geographically adjacent channel use. However, the FCC has not adopted improved receiver technical standards. It is the position of the Commission that receivers do not cause interference, nor do they threaten effective operation of the public safety network, as would substandard transmitters.
Because of the demand for limited spectrum, it is the intent of this Plan to provide efficient spectrum utilization within current technological capabilities. Agencies are encouraged to carefully consider the receiver selectivity specifications of any equipment to be purchased for use in the 821-824/866-869 MHZ band. Poorly designed receivers may cause serious degradation of the system in areas using adjacent channels.
9.9 Absolute Mileage Separation
In any case where the radio service areas of adjacent channel systems are separated by at least 70 miles, or co-channel systems separated by 100 miles, the interference studies as set forth in this Plan are unnecessary because of free space and terrain losses.
As referenced in the "National Plan", trunking is mandated for any new system with more than four channels in the 800 MHZ band when located at a single transmitting site. Requests for exceptions will be considered by the Arizona Regional Review Committee for mobile data use, encryption, and telemetry stations. Other requests for waiver of the trunking requirement will be considered after presentation of evidence by the requesting agency. Approval to waive the trunking requirement will be based on the individual merits of the presentation, and will be subject to FCC final approval.
9.11 System Loading Requirements
An agency requesting a single frequency to replace a frequency currently in use, that will be turned back for reassignment, will not be required to meet loading requirements in order to obtain the new frequency. However, if the single frequency is not loaded to more than 50 units within three years after the license is granted, the frequency will be available for assignment to other agencies on a shared basis. Shared use of a frequency is not interference free. Users of single frequency systems will be required to provide the ARRC "confirmation of loading" for mobiles and portables as a method of validating system loading. This required updating shall be done annually until minimum loading has been completed.
This exception shall apply to agencies which have only one system and a single frequency. Agencies requesting additional frequencies or having multiple systems shall comply with the loading standards as outlined in the loading tables or provide a "Traffic Loading Study" that meets the criteria as listed in the loading tables.

9.12 System Engineering Requirements
All requests to the ARRC for frequencies must include sufficient data for the Committee to be able to determine proposed system operating parameters and shall be considered a system engineering exhibit.
The system engineering exhibit must show:
9.13 Average Elevation Exhibit
An additional exhibit showing the average elevation of the terrain of each of the eight main radials is required. If an outside source is used for the calculation of average terrain, a copy of this report may be substituted for the average elevation exhibit.
9.14 Public Switched Telephone Network (PSTN) Interconnect Use
The applicant of a 800 MHZ trunked radio system may use an interconnect to Public Switched Telephone Network for systems implemented under this Regional Plan. However, the use of cellular telephones (or other telephone interconnect systems) for automatic interconnect to the Public Switched Telephone Network is recommended. Utilization of cellular telephone networks will not impact radio systems implemented under this plan.
9.15 Frequency Allocation List
The frequency allocations contained within this Plan are based on the current and projected needs and system loading through the year 2010. The basis for this frequency allocation listing was taken from a population growth study done by Mountain West Research, completed June 6, 1989. All cities in Arizona with a population above 10,000 in the 1980 Census were extrapolated using county population growth projections for the year 2010. Channel allocation per town is based on one channel per 25,000 population, with a minimum of two channels.(Appendix IV.)
All regional systems being installed by larger entities such as Counties or State are required to allow shared secondary use of the regional system for rural users. All large area systems are encouraged to solicit participation by the rural entities to better facilitate spectrum efficiency, and to provide better communications capability for the rural users. (Refer to Appendix IV for frequency listing.)
All authorizations under this plan shall utilize equipment that complies with all applicable technical standards of the Federal Communications Commission.

ARTICLE I - NAME AND PURPOSE OF ORGANIZATION
The name of this organization shall be the "Arizona Regional Review Committee", abbreviated "ARRC". This committee shall exist under authority of the Arizona Regional Public Safety Plan (ARPSP), as adopted by the Federal Communications Commission (FCC) under PR Docket 91-143, on September 4, 1991.
The purpose of this committee is to function as a frequency coordinating and advisory body for 800 MHZ Public Safety channels approved by the FCC under the National Public Safety Advisory Committee, known as the NPSPAC plan. This plan was adopted by the FCC on November 24 , 1987. It shall also function as a coordinator and clearing house for reallocated channels, known as "give backs" in other Public Safety spectrum outside the NPSPAC channels. All functions of this committee shall be in accordance with the ARPSP, as amended.
ARTICLE II - COMMITTEE MEMBERSHIP
First election of the 11 member ARRC was conducted at an organizational meeting held on August 21, 1991. These members shall remain on the Committee until resignation, removal for cause, or the member leaves their current public safety eligible agency. Removal for cause shall require a majority vote of the quorum at an open general meeting.
A vacancy on the Committee shall be filled through nominations at the next regular scheduled, publicized, open public meeting, and voted upon thereat. A majority of votes of the voting agencies (one vote per eligible agency) shall be required to elect to the Committee.
Members may be removed for cause for non-participation under the following guidelines:
Members will be required to attend one-half of the meetings of the Committee or their respective subcommittee through the year. Attendance at fewer than one-half of these meetings shall be cause for review of participation by the Executive Committee during its meeting prior to the July ARRC meeting.
Should the Executive Committee find that a member has not been participating at the level required the Excomm will report to the general committee at the July meeting and schedule an open public meeting to allow voting for the removal for cause of the non-participating member. Prior to this meeting the ARRC Chairperson shall correspond with the member in question, informing the member of the committee's intention to remove for cause and advising the member of the date of the meeting at which the action will take place.
The vacancy created by removal of a member for cause shall be filled, if possible, at the same open public meeting at which the removal is approved.
Nominations for the vacancy will be taken from the floor as stipulated in Article III.C.1.b.
ARTICLE III - OFFICERS OF THE ARRC
The officers of the ARRC shall consist of a Chairperson, Vice- Chairperson and combined Secretary/Treasurer.
Elections shall be held annually at the regularly scheduled meeting of the ARRC in September. Nominations shall be made at the regular scheduled meeting in July.
A nomination sub-committee shall be appointed, with the immediate past chairperson of the ARRC as chair-person, or in the event of their unavailability, the previous past chairperson. If no past chair-person is available, the Executive Committee shall serve as the nominating subcommittee.
Nominations may also be made from the floor at the nominations meeting. Nominees must be present at this meeting and have the commitment of their sponsor to fully participate.
ARTICLE IV - OPERATING RULES OF THE ARRC
Regular meetings of the ARRC shall be scheduled in coordination with the scheduled meetings of the Arizona APCO, Inc. chapter. In addition, two semi-annual meetings scheduled in conjunction with Arizona APCO shall be designated as "Open Public Meetings" with open participation from the public safety community. Each public safety entity shall be apportioned one vote at each open, public meeting. Designated alternatives and representatives shall be identified prior to the meeting.
Meetings shall be conducted at the appointed time and place by the Chairperson, or in their absence, the Vice- Chairperson, or in their absence, the Secretary/Treasurer.
Meetings shall be conducted according to Robert's Rules of Order.
As a minimum, a financial statement shall be read to the membership, and subcommittee reports presented. Applications for NPSPAC frequencies which have been previously reviewed and approved by the appropriate subcommittees shall be voted upon, and approved by a two- thirds vote of the quorum present.
The ARRC may conduct business at any publicized, scheduled meeting, with a quorum consisting of a minimum of six members present, which shall include at least one officer. Voting by proxy, with written authorization, shall be permitted.
In special situations relating to license applications, vote by telephone and confirmed by fax or e-mail may be made provided ALL members are contacted by voice and fax or e-mail, and given a chance to respond with a vote. A two-thirds vote of all members is required for approval of the issue. Results of the telephone/fax/e-mail vote must be recorded in the minutes of the following meeting.
The Executive Committee, to be known as the "Excomm", shall consist of the current Chairperson, Vice-Chairperson, Secretary/Treasurer, and immediate past Chairperson. Subcommittee chairpersons may be asked to attend meetings of the Excomm as required.
Meetings shall be called a minimum of three times annually for the purpose of conducting business of the ARRC, and for review of subcommittee operations and work. The meetings shall be called and scheduled by the ARRC chairperson.
There shall be five (5) standing subcommittees of the ARRC. These shall include:
The NPSPAC Application Subcommittee shall meet at least monthly if applications are pending. The subcommittee shall make recommendations on applications in a timely manner to the ARRC for voting upon at the next regularly scheduled ARRC meeting. Evaluations shall be performed in a manner consistent with the criteria established in the Arizona Regional Public Safety Plan (ARPSP), as amended.
Application evaluations may be delayed if, in the subcommittee's opinion, insufficient information was provided to make a determination. In such case, the subcommittee chairperson shall draft a letter to the applicant within ten (10) days of the initial subcommittee review, of the insufficiency, and shall request specific information necessary to make a determination. If such requested information is not provided within thirty (30) days of the mailing of such letter, the application shall be deemed defective, and returned to the applicant. Approval recommendations shall require a unanimous vote of the subcommittee members present at the evaluation meeting. Rejection of an application may be appealed within forty-five (45) days as per paragraph 7.7 of the ARPSP.
The subcommittee shall return applications for systems requiring both NPSPAC and non-NPSPAC frequencies with the suggestion that the applicant request only NPSPAC frequencies. The subcommittee shall actively work with the applicant agency to create a system utilizing NPSPAC frequencies.
Any ARRC member shall be disqualified from evaluating and/or voting on an application submitted by their sponsor political subdivision, or non-political entity. In this case, the member-applicant shall act only as an advisor, providing necessary information upon which to make a recommendation, and shall not be considered a member of the subcommittee or the ARRC for voting purposes.
Recommendation of the subcommittee shall be voted upon at the next regularly scheduled meeting of the ARRC, and shall be approved with a two-thirds vote of the quorum.
This subcommittee shall meet at least monthly if applications for "give back" frequencies are pending. The subcommittee shall keep a chronological listing of agency requests for "give back" channels. Each request for channels shall be accompanied by a statement of need. a separate list shall be maintained for each primary public safety frequency band.
The subcommittee shall evaluate such applications on their merits, in conformance with the ARPSP, and make a recommendation in a timely manner to the ARRC when frequencies become available. Where there are multiple applications with relatively equal merit, the subcommittee shall give preference to the longest standing application.
Recommendations from the Subcommittee to the ARRC may be delayed if there is insufficient data submitted to make a determination. The same procedure shall be followed as in Article VI.B.2. If insufficient information is forthcoming, an application for a "give back" channel may be dismissed and returned to the applicant.
Any ARRC member shall be disqualified from evaluating and/or voting on an application submitted by their sponsor political subdivision, or non-political entity. In this case, the member-applicant shall act only as an advisor, providing necessary information upon which to make a recommendation, and shall not be considered a member of the subcommittee or the ARRC for voting purposes.
Recommendation for approval by the subcommittee shall be unanimous, and shall be voted upon at the next regularly scheduled meeting of the ARRC, and shall be approved by a two-thirds vote of the quorum.
The Bylaw Review Subcommittee shall meet at least semi- annually to review any needed changes to the Bylaws, and draft such changes for presentation to the Excomm.
The Nominations Recommendation Subcommittee shall meet annually prior to the nominations meeting for Excomm officers, and shall present a selected slate of candidates as nominees for Chairperson, Vice-Chairperson, and Secretary/Treasurer to the ARRC membership at the nominations meeting.
The Regional/Interregional interoperability Subcommittee shall meet monthly, if there is an application for NPSPAC channels pending.
The subcommittee shall make a recommendation as to whether an applicant should be required to place in service "Common Calling" and/or "Interoperability" stations as a condition of application approval. Specific recommendations shall be made in writing to the ARRC Chairperson. Such recommendation shall be made a part of the final vote by the ARRC for approval of a NPSPAC application.
The subcommittee shall monitor licensing activity in surrounding regions to ensure compatibility of frequency usage, and coordinate "Common Calling" and "Interoperability" installation and monitoring.
The subcommittee shall also monitor FCC Regulations and coordinate with the nation of Mexico to ensure compatibility of channel usage and "Common Calling" and "Interoperability" along the U.S./Arizona and Mexico border.
The chairpersons of the standing subcommittees shall be appointed by the ARRC Chairperson, with concurrence of the majority of the Excomm present at a scheduled Executive Committee meeting.
There shall be a minimum of three (3) members on the "800 MHZ NPSPAC Application Review" and "VHF/UHF/800 MHZ Frequency Reassignment" standing subcommittees, including the chairperson.

PROCEDURE FOR DETERMINING SERVICE AREA
RECOMMENDED PROCEDURE FOR DETERMINING SERVICE AREA
EXAMPLE
The service area of a 100 watt ERP station with an antenna height above average terrain of 450 feet would be calculated as follows:
P(dBk) = 10 X log (100) -30
= 10 x 2 -30
= -10
F(DbU) = 41 - (-10)
= 51 DbU
From the look-up tables, 51 falls between 50.5 in the 400 ft. column and 52.9 in the 500 ft. column. The corresponding mileage would be 12.

INTERAGENCY RADIO SYSTEM PLAN
January 1996
The Arizona Inter-Agency Radio System (IARS) is designed to provide a supplemental communications capability to police, and other personnel of municipal, county, state, or federal agencies performing public safety activities. The system assists agencies requiring a radio contact with another agency's unit concerning a public safety activity in which the nature of the emergency or activity dictates that the use of regular radio channels would not adequately provide the communications capability necessary to successfully complete the operation. Matters relating to life threatening situations will have priority in the use of this system. Agencies participating in IARS shall render a communications service to itinerant law enforcement vehicles and other public safety users having emergency communications needs. This system operates on designated Police Channel frequencies.
The Arizona Chapter of the Associated Public Safety Communications Officers (A.P.C.O.) shall serve as the state plan governing entity.
** CTCSS requirements see below.
IARS VHF Mobile receive 155.475 MHZ no PL required.
Mobile transmit 155.475 MHz no Pl required **
This frequency is designated by the FCC as the National Police
Emergency Channel.
** CTCSS will be added to protect base stations from interference. A tone frequency of 156.7 Hz (as used in the 800 MHZ national plan) is the currently chosen tone frequency for VHF, the UHF channel will continue to utilize the current 100 Hz tone frequency. A second CTCSS tone may be added for system/site selection. Mobiles will be required to transmit the CTCSS but will operate carrier squelch on receive. VHF base stations will then no longer transmit a CTCSS to protect other base stations from interference.
Each support control agency shall monitor the IARS channel(s) at all times. The monitoring system should have a range comparable to that of the agency's own mobile-to-base radio receiver.
In order to assure the availability of the channel in times of emergency, strict discipline MUST BE MAINTAINED. This can be accomplished by: 1) good operating procedures, and 2) adherence to FCC rules and the rules of the IARS Committee as herein stated or hereafter amended.
The established priority use levels for the system are described below. When a higher priority of use is required, all lower priority use must cease in ANY area where interference could occur.
The four priority levels are:
PRIORITY 1: Disaster and extreme emergency operations of large scale; for mutual aid and interagency communications.
PRIORITY 2: Emergency or urgent operations involving imminent safety of life or property.
PRIORITY 3: Special event control activities, generally of a pre- planned nature, and generally involving joint participation of two or more agencies.
PRIORITY 4: Drill, maintenance, and test exercises of a civil defense or disaster nature.
Generally, any action requiring emergency communications coordination between mobile units that the individual agency's regular radio facilities could not adequately provide is acceptable traffic. SELF-DISCIPLINE AND SELF- POLICING BY THE PARTICIPANTS SHOULD SUFFICIENTLY CONTROL THE SYSTEM SO THAT IT WILL BE AVAILABLE IN TIMES OF EMERGENCY.
OPERATIONAL GUIDELINES
FREQUENCIES
IARS operates on VHF, 155.475 MHZ, as designated by the FCC as the Nationwide Police Emergency frequency. UHF operation is on 460.375/465.375 MHZ, the frequency pair designated by the AZ IARS Committee and the Arizona APCO Frequency Advisory Committee, and licensed by FCC, assigned in Arizona for that use. Most of the transmitter sites have the provision to cross-patch the VHF and UHF radios for cross-band operation. The UHF mobile relay station also supports car-to-car repeat through the selected site. In general, this cross-patch and repeat function is automatic upon receipt of a signal from a mobile or control station. Operation on VHF and UHF is complemented by the Inter-Agency channel operation designated in the Arizona Regional 800 MHZ Plan. Agencies with 800 MHZ systems may support cross-band operation through console cross-patch options.
OPERATIONS
A mobile unit calling with emergency traffic should use one of the following sequence examples. NOTE: All broadcasts will be in plain language only. (No Ten codes etc, ie. DCSO is CODE 10-23 ?).
