1.0 INTRODUCTION
1.1 Project Background
The Town of Cheshire (the Town) is undertaking a comprehensive initiative to modernize its current emergency communications system. The stated primary goals of the initiative are to maximize efficient use of frequencies, equipment, network and interoperable conditions for Town-based communications in the following ways:
1. Replace end-of-system life of the current equipment configuration with new equipment retaining only those components that are not near end of life such as radio subscriber units. The New systems must incorporate areas of best practice for system reliability, survivability and redundancy.
2. Rectify town-wide coverage deficiencies that exist in critical areas of the service area by developing a four-site simulcast transmitter/receiver system to bring area-wide coverage to APCO standards.
3. Development of an interoperable communications system environment for incident-based communications between Cheshire’s mission critical agencies and dispatch that also provides communications to other Town agencies and Cheshire Public Schools.
The Town has a land area of approximately 33 square miles and a population of approximately 29,000. It is bordered by eight other incorporated municipalities and both Interstates 84 and 691 pass through Town.
Radio communications are crucial to the day-to-day operations of both the Cheshire Police Department and the Cheshire Fire Department. The Department of Public Works and the Cheshire Public School system utilize radios in their day-to-day operations. The police department operates a two- position Public Safety 911 Answering Point (PSAP).
The current Cheshire Police and Fire radio systems and dispatch consoles have been in place for many years and the last upgrades have been purchased for the existing systems. The current system infrastructure and consoles will be supported by Motorola through 2018 at which time support for the majority of the components will be discontinued. Existing Motorola brand XTS portable radios and XTL mobile radios used by both police and fire are due to go out of support in 2019-2020. Recently purchased APX mobile and portable radios have no planned obsolescence in the foreseeable future.
The Cheshire Police Department has an authorized strength of 48 sworn officers and a fleet of approximately 25 vehicles. All officers are issued portable radios from an inventory of 60 portable radios. Most of the vehicles are equipped with both a Cheshire mobile radio and Connecticut State Police Emergency Radio Network (CSPERN) radio. The CPD has 32 mobile radios in its inventory.
The Cheshire Fire Department maintains an inventory of 74 portable radios assigned to various FD personnel and apparatus. The CFD has 31 mobile radios, 10 of which are dual control heads.
The Cheshire Public Works Department, Recreation Department and Water Pollution Control Division have a combined staff of 39 and a fleet of approximately 41 radio equipped vehicles. The departments also have approximately 15 portables, 4 control stations and 7 desk units.
1 | Page Land Mobile Radio Systems RFP: Town of Cheshire Public Safety Communications System
The Cheshire Public Schools have 7 main school buildings including a high school, a middle school, four elementary schools that are K-6 and a kindergarten center. In addition to the 7 main school buildings, there is a central office building that also houses a small school facility, a school bus depot and a maintenance garage that houses four administrative offices. Each school uses radios for internal communications between the administrators, custodians, and select other staff. There are approximately 167 Motorola XPR 3500 radios used across the school district ranging from as few as 5 in our smaller buildings to more than 20 in our larger buildings. There are other radios used that vary in age with the older equipment consisting of a wide variety of makes and models and are generally operating on UHF frequencies in the business radio service. Although there was never a standard radio specification for school radios, the replacements that have been purchased for failed radios in the last two years are digital Motorola XPR 3500 series operating on UHF channels. It is important to note that none of the radios currently have the ability to communicate between buildings or to police or fire officials. The school bus fleet, is equipped with 3 mobile radios used by the depot staff with 12 radios installed in school owned vehicles all of which are analog and aged and operate on a low band frequency. A private school bus contractor transports the majority of school children in Cheshire. Their 40 buses are equipped with low band radios owned and operated by the contractor. It should be noted, both low band frequencies used for school buses both private and town owned are connected to the police dispatch console.
The primary communications systems servicing the Town are:
Town of Cheshire Police Department UHF system (2 channels) Town of Cheshire Fire Department VHF system (3 channels) Cheshire Public Schools utilize 8 or more standalone radio systems with portable-portable operation Department of Public Works VHF system (1 channel)
1.2 Existing System Overview
The Town of Cheshire operates a number of conventional repeater systems to support police, fire, public works and school communications. Cheshire Police Department operates on two UHF repeated channels using Motorola ASTRO digital modulation while the Fire department and Department of Public Works operate in the analog mode each on a unique repeated VHF channel. Cheshire Public Schools operate on a broad range of standalone radio communications equipment and radio units. Several of the schools have purchased and are introducing Motorola MOTOTRBO radio communications system in the UHF frequency band. All but one of the public schools, the Dodd School, are serviced and supported by Utility Communications, a MOTOTRBO distributor, the primary system supplier of both the infrastructure and radio units.
The first responder radio infrastructure equipment is aged and has or will very soon reach the end of its life cycle and maintenance support from the vendor. A majority of the mobile and portable radio fleet varies from legacy equipment that has reached the end of its product life and maintenance to several years old.
Communications Center and Back-Up Capability
The Town of Cheshire operates a combined 911, police and fire dispatch center. There are two dispatch consoles located in Police Headquarters at 500 Highland Avenue. There is an additional console located in Fire Headquarters at 250 Maple Avenue. Consoles located at both locations are connected to their own Motorola Centracom Gold Elite Central Electronics Bank. The electronics and the software running the console system is far beyond end of life and is beginning to present a maintenance challenge since the
2 | Page Land Mobile Radio Systems RFP: Town of Cheshire Public Safety Communications System
availability of replacement parts is diminishing.
Call taking and dispatching for both police and fire takes place at Police Headquarters while the console at Fire Headquarters is used by the fire department to supplement the police dispatchers during major fire events and for the convenience of fire personnel in the fire station. Police dispatch receives approximately 23,911 calls and fire receives about 900 calls annually. Calls are entered into CAD and dispatched on the primary police radio channel. Fire calls are dispatched by sending a two-tone sequence and voice announcement over the primary fire dispatch channel.
Backup dispatching is limited as the dispatch console at Police Headquarters has fire channels programmed in it however Fire dispatch consoles do not have Police channels programmed. The dispatch configuration at the Fire Department is supplemented with table-top radios at each fire station. This allows for some form of dispatch to continue in the event of a console crash provided the VHF fire repeater system is functioning.
The telephone and CAD systems at police headquarters are not connected in any way to the radio consoles.
The two position police dispatch center is manned by civilian and sworn personnel. The dispatch consoles have capability to operate on 12 base station interfaces which include:
Police Fire Fire Hotline South Central InterCity School bus Public Works SCAN (Southern Regional UHF conventional) Police hotline WARN (Western Regional UHF conventional) 800 MHz ITAC (8TAC) channels
Dispatchers are responsible for answering all incoming calls; process and dispatch town-wide E911 calls and manage incoming administrative calls for police and fire. Dispatch is also responsible for activating the fire page which uses a two-tone alerting system with voice announcement.
In addition to limited dispatch console back-up capabilities, there is a lack of alternate infrastructure that can be used should any of the single-site repeaters fail in the existing system., in the current configuration that depends on a single site transmitter configuration, if the antennas at Police Headquarters become unusable, there is no alternate system that can be used for first responder communications. This goes for the fire and DPW systems as well. This actually occurred recently on the Cheshire Police radio system where a transfer switch hung up disabling the police communications repeater system.
Interoperability is achieved between the various town agencies and neighboring communities that operate on disparate radio channels through patching or direct console communications with frequencies available on the radio console. The Police Dispatch console provides an alarm indication of repeater or voting system failure and provides door control functionality for 7 doors in police headquarters including garage, sally port doors, main lobby and rear doors while displaying repeater status and voting system failures.
Dispatchers are responsible for monitoring select Town infrastructure such as in-building water flow and
3 | Page Land Mobile Radio Systems RFP: Town of Cheshire Public Safety Communications System
gas tank alarms that are independent of the radio console system.
Mutual Aid Interfaces and Interoperability
The police dispatch console has access to all of the first responder channels used in Cheshire as well as a number of base stations connected to the console system for mutual aid and interoperability with surrounding communities. These include a UHF radio on the police channels of adjacent towns and the statewide mutual aid VHF fire channel. Lacking is a connection to school security which is operating without an infrastructure on a radio-to-radio basis within each school.
When there is a need to communicate across town agencies the police dispatcher can establish communications on channels of other town agencies and relay any necessary information. Although somewhat functional, during busy times it may be a burden on the police dispatcher to perform this function in a timely manner. As both fire and public works operate on the VHF frequency band consideration should be given to have both agencies configure their respective radios with their respective agencies channels. This would provide direct interoperability between fire and public works without dispatcher intervention.
Mutual aid communications for police is primarily through the dispatcher using a control station on the adjacent town’s police frequency or through one of the statewide or regional interoperable systems. Direct communication is possible from police mobile and portables if the UHF frequency of the neighboring department is programmed into the Cheshire radios.
Mutual aid for fire is provided through a common VHF fire frequency that is shared with surrounding communities and a low band statewide mutual aid channel between dispatchers.
Direct interoperability with surrounding communities can be enhanced for both police and fire through the deployment of all band radios. The implementation of all band radios will provide a direct method of interoperable mutual aid communications with any neighboring community provided permissions for operation on these systems are obtained.
The primary transmitter site for both UHF police frequencies is located at Police Headquarters, 500 Highland Avenue. A secondary set of police repeaters is located at Fire Headquarters, 250 Maple Avenue.
The police repeater system is enhanced by additional receivers located at:
1686 Waterbury Road, Darcey School 1125 South Main Street, Fire Station 3 1325 Cheshire Street, Water Treatment Plant
The fire department and public works VHF repeater transmitters are located at Fire Headquarters, 250 Maple Avenue.
The public works repeater is standalone without any additional receivers. The fire repeater is enhanced with additional receivers located at:
1125 South Main Street, Fire Station 3 1325 Cheshire Street, Water Treatment Plant 1119 Summit Road, Cell Tower
4 | Page Land Mobile Radio Systems RFP: Town of Cheshire Public Safety Communications System
The current site configuration within the Town is shown on the figure 1 below.
Figure 1 -Map of Tower Sites
5 | Page Land Mobile Radio Systems RFP: Town of Cheshire Public Safety Communications System
Law Enforcement
The Police communications system consists of a two channel UHF conventional repeater system operated in the ASTRO digital mode. Each repeater located at police headquarters has a duplexer with a shared receive and transmit antenna located on the top of the 160 ft (nominal) tower. With two independent repeaters they each provide a level of survivability should either one of them fail. This configuration however, does not protect against total site failure since both repeaters are co-located at police headquarters.
Talk back communications is enhanced with additional receivers located at the Water Treatment Plant, the Darcy School, and at Fire Station 3. Although there are remote receivers located throughout the Town, it is the height of the antenna placement that negatively impacts the existing system coverage as the antennas are mounted on low level roof tops or telephone poles. The voting system talkback system evaluates the quality of signals received from the receivers in the system. The system is located in the equipment room at Police Headquarters along with the dispatch console interface equipment.
Police have reported less than acceptable radio coverage in the northwest part of town near the Darcy School, in the northeast near the Water Treatment Plant, as well as in the eastern portion of the service area near the reservoir
Fire
The fire system consists of a single frequency VHF repeater located at 250 Maple Avenue, Fire Headquarters. The transmit/receive antenna is mounted at the top of the 100 ft tower located at this site. The single antenna is used for both transmit and receive using a duplexer to connect the repeater. The primary fire repeater is supported by remote receivers located at Fire Station 3, the Summit Road tower, and the Water Treatment Plant. There is a backup repeater with a single antenna at the top of the 160 ft. (nominal) tower at Police Headquarters, 500 Highland Ave. In addition to the repeaters on the primary fire channel there is an additional VHF high band base station and an additional VHF low band base station licensed and operating on frequencies for interoperability with surrounding communities.
The console system at fire headquarters is used by fire personnel within the station for regular incident communications with fire personnel and not as a dispatch console. All dispatching is done from police headquarters. Fire calls are received at the Cheshire Police Department via 911 and 7‐ digit phone lines. Police dispatchers answer the call and after determining the need for the Fire Department, send a sequence of two‐tone signaling and a voice announcement on the VHF fire dispatch channel. The Fire Dispatch console is not configured to monitor system status or alarm conditions. The fire department is also licensed for a VHF high band mobile‐only frequency for fire ground operations. The console has the capability to control overhead doors, gas pumps, etc.
The primary concern for the Fire Department is dead spots located throughout the service area:
South end of town, south of Cook Hill North end of town north Sandbank I-84 in various spots
Several fire vehicles are equipped with dual band VHF/UHF mobile radios to provide interoperability with several communities using UHF frequencies for fire communications.
6 | Page Land Mobile Radio Systems RFP: Town of Cheshire Public Safety Communications System
Recording System
Cheshire utilizes a VPI recording system which records 7 telephone lines and 5 radio frequencies. Both the police and fire departments make use of this single recorder connected to the system.
EMS
Ambulance service is provided by a contract vendor that operates on the statewide EMS system. The medic unit that covers Cheshire has capability of operation on the police channel for coordination purposes. Medical 911 calls answered in Cheshire are transferred out to the dispatcher for the private service.
School Communications
School personnel communicate with each other directly using a combination of UHF and family-service radios. Most communication is intended for internal school use which does not require a supporting infrastructure in order to function. There is no infrastructure used for receiving and sending radio signals anywhere throughout the school building. The lack of infrastructure impacts each of the schools ability to directly contact the Police Dispatcher via radio for assistance. There has been a concerted effort made to upgrade the radio communications systems within the schools through a strategy of deploying commercial grade radios (Motorola XPR 3500s) communications system that can operate on existing frequency bands now in use within the schools. The new system has the ability to be “networked” to other similar systems within the district and can be connected to a dispatch console at police headquarters to be used in case of emergency.
Transportation Communications
The majority of Cheshire students are bused by a private bus contractor. The contractor has their own radio system where communications is maintained with their buses from their dispatch office. The contractor’s office is co-located in an office trailer with the Cheshire Board of Education bus transportation personnel. There is no direct communications between the bus contractor and first responders other than direct telephone communications dispatcher-to-dispatcher.
The Board of Education operates a number of buses for special transportation needs of students. The Board operated buses are equipped with low band radios operating in the 46 MHz band and communicate to a base station at the Board office at 29 Main Street. The single site base station provides general radio coverage throughout the town with a number of dead spots. The police dispatcher does have the ability to operate on this channel when necessary.
Public Works
A single VHF repeater located at Fire Headquarters provides communications to the vehicles operated by the Public Works Department. Primary dispatching is done through four table top control stations at several locations in Cheshire. The public works frequency is also tied in to the police dispatch console to provide interoperability for necessary communications. The Department operates 41 mobiles and 15 portable radios. Most of the communications is to mobile radios and enhanced portable radio coverage was not mentioned as an issue. A concern of the Department is the need for a backup repeater as there have been repeater failures that resulted in a total loss of radio communications. There is no dispatcher on this system as most communications are between mobile users and their garage. The Public Works uses identified the acoustics in the garage as a factor in establishing clear radio communications.

Connectivity
Connectivity for the remote receiver sites back to Police Headquarters is provided over leased T1s from AT&T. These connections have proven to become increasingly unreliable over time causing downtime impacting first responder ability to maintain effective communications.
The Town has constructed a fiber system (refer to Figure 2 below) to connect Town-owned buildings including schools and fire stations. Figure 2 illustrates the configuration of the fiber system with the hub of service terminating at Police Headquarters. From the hub, connectivity is in place to Town Hall, Fire Headquarters and each of the eight public schools. Any new system can take advantage of this fiber system to provide connectivity between equipment locations on a town-wide radio network or to connect the schools for a future radio communications infrastructure.

Aged Infrastructure
The first responder radio infrastructure equipment, which includes the repeaters, receivers, comparators, and dispatch consoles are aged and have or will very soon reach the end of their life cycle and maintenance support from the vendor. Additionally, mobile and portable radios in Cheshire vary from legacy equipment to newer radio units that are only a few years old. The radio units that have reached the end of product life and maintenance will not be reusable however radio units that are just a few years old may be reusable in the new system with the proper software upgrades and reprogramming.
The impact of operating an out-of-life has two important effects:
The manufacturer no longer provides enhancements or improvements to the existing system such as additional receivers. More importantly at end of life the manufacturer stops producing replacement parts and depends on the inventory in warehouses to support existing systems until the replacement parts are exhausted. At some point there is a possibility of system failure that cannot be remediated.
Because of these conditions, proactive development of updated configurations and equipment is essential to maintaining the safety and survivability of first responders.
Subscriber Equipment
Town-wide public safety first responder systems support approximately 450 mobile, portable and control station radios on three frequency bands VHF High Band, VHF Low Band and UHF. These radios are used by police, fire, public works, school security and school buses. The subscribers are distributed as follows.
Portables Mobiles Control Stations Desktop Remotes
Police 60 35 8 4
Fire 74 31 5 7

2.21 Award Criteria; Selection; Contract Execution
An evaluation process will be implemented to allow for a fair review of all acceptable proposals. An evaluation team will consist of various Town representatives and consultant team as determined by the Town. The evaluation team will serve to recommend an award of contract to the Town of Cheshire which shall be based on the best interests of the Town.
All proposals received by the deadline will be evaluated; each proposal shall be reviewed for completeness and conformance to the mandatory technical and administrative submittal requirements of the RFP. The evaluation team at its sole discretion may request Vendors to submit additional information or provide clarification of those sections or requirements deemed incomplete. The Town reserves the right to reject any and all proposals or parts thereof. If a proposal does not meet the mandatory requirements, the proposal may be disqualified.
Prospective Vendors who submit a proposal in response to this RFP may, at the Town's sole discretion be invited to make an oral presentation and/or submit a written clarification of their proposal. Vendors who decline this invitation will be disqualified. Such presentations will provide an opportunity for the vendor to clarify or elaborate on the proposal but will in no way change the vendor’s original proposal. If there is a discrepancy between oral statements and the written contents of the submitted proposal, the written proposal shall control. No comments regarding other vendors or proposals shall be permitted, and Vendors may not attend presentations made by their competitors. Vendors must clearly understand that it is the Town’s sole option to determine which Vendors, if any, will be invited to make oral presentations. Vendors should not construe an invitation to any vendor to imply acceptance or rejection of any proposal. The Town will schedule the times and locations of any such presentation.
Although the cost reflected in the proposals submitted in response to this RFP will be a significant factor in determining an award hereunder, the Town reserves the right to award the contract based upon additional factors which may, in the sole discretion of the Town, be equally important to meet the needs of the Town. The Town reserves the right to award the contract based upon the proposal that presents the "best value" in goods and services to meet the Town's needs. Therefore, the Town may award a contract hereunder to the Vendor which optimizes quality, cost, efficiency, and compatibility with existing Town systems and facilities among responsive and responsible vendors and found to be in the best interests of the Town.
The Town will evaluate all complete RFP responses based on, but not limited to, the following criteria categories.
Ability of the proposed system to meet the requirements of the Town Delivered equipment & services on a ‘TURN-KEY’ basis System functionality, expandability, design & features State-of-the-art technology as specified in the RFP or better Equipment features Preservation of functionality of existing systems Exceptions, clarifications and/or substitutions to the requirements of the RFP Proposed statement of work Prospective Vendors compliance with the instructions of the RFP Radio coverage maps and engineering parameters System design that meets coverage requirements as specified in Radio Coverage 3.8.

The contract, if awarded, will be to the Vendor who in whole or in best meets all terms of the specifications and project requirements. Nothing in this RFP or the award of a contract, if any, shall be construed as a guarantee of a minimum or maximum contract or contract term. The Town reserves the right to award the project to the responsible vendor whose proposal best optimizes quality, cost, efficiency, and compatibility and found to be in the best interests of the Town.
The contract award process with the preferred Vendor is anticipated to begin within 45 calendar days of the opening of the RFP responses. Notice of award will be sent to the preferred Vendor by US mail and email notification. Unsuccessful responding Vendors shall also be notified. The Town of Cheshire reserves the right to enter into contract negotiations with an unlimited number of preferred Vendors resulting from the outcome of the RFP evaluation process.
A contract will be required by the Town for the implementation of the project defined by this RFP. The Vendor shall be expected to sign a standard contract included in Appendix E and agree to all Town provisions identified in Appendix A. The Town of Cheshire will not sign any company standard service agreement, contract or any other form of agreement. The Town reserves the right to extract certain language from the company’s service, software, or maintenance agreement and incorporate it into a contract if mutually agreeable. Specific work assignments, final project scope and schedules, and definition of project deliverables may be further specified during contract negotiations based on information submitted within the RFP response, or presented during the interview process. If the Town is not able to enter into mutually agreeable terms and conditions with the preferred Vendor, the Town may elect to enter into contract discussions with another responding Vendor.
All proposals will be publicly opened and read aloud as received on the date, at the time, and at the place identified in this RFP. Proposers may be present at the opening.
The Town reserves the right to correct, after proposer verification, any mistake in a proposal that is a clerical error, such as a price extension, decimal point error or FOB terms. If an error exists in an extension of prices, the unit price shall prevail. In the event of a discrepancy between the price quoted in words and in figures, the words shall control.
The Town reserves the rights to accept all or any part of a proposal, reject all proposals, and waive any informalities or non-material deficiencies in a proposal. The Town also reserves the right, if applicable, to award the purchase of individual items under this RFP to any combination of separate proposals or proposers.
17 | Page RFP: Town of Cheshire Public Safety Communications System
The Town will accept the proposal that, all things considered, the Town determines is in its best interests. Although price will be an important factor in most RFPs, it will not be the only basis for award. Due consideration may also be given to a proposer’s experience, references, service, ability to respond promptly to requests, past performance, and other criteria relevant to the Town’s interests, including compliance with the procedural requirements stated in this RFP.
The Town will not award the proposal to any business that or person who is in arrears or in default to the Town regarding any tax, debt, contract, security or any other obligation.
If the lowest proposer meets all specifications, is responsive, and, if applicable, qualified, but the proposal is not acceptable to the Town Manager or, if applicable, the Public Building Commission or the Board of Education, the matter must be referred to the Town Council for its decision on whether to reject all proposals, to accept a higher proposal, or to take such other action as may be in the Town’s best interests.
The Town will select the proposal that it deems to be in the Town’s best interest and issue a Preliminary Notice of Award to the successful proposer. The award may be subject to further discussions with the proposer. The making of a preliminary award to a proposer does not provide the proposer with any rights and does not impose upon the Town any obligations. The Town is free to withdraw a preliminary award at any time and for any reason. A proposer has rights, and the Town has obligations, only if and when a Contract is executed by the Town and the proposer.
If the proposer does not execute the Contract within ten (10) business days of the date of the Preliminary Notice of Award, unless extended by the Town, the Town may call any proposal security provided by the proposer and may enter into discussions with another proposer.

Testing points within each grid shall be randomly chosen. All randomly chosen test points must be within the service area.
This automated coverage test shall incorporate critical time constants for VHF RF coverage testing. A method of correlating the location and the BER measurement, such as a GPS receiver, shall be employed to assist with the subsequent coverage performance analysis. The testing instrumentation shall be configured to allow use both on foot and in a vehicle, and shall simulate a portable radio, worn at hip level, for all grids covering any portion of Town. The testing instrumentation shall be verified by an independent means acceptable to the Town both before and immediately following the test. Test equipment shall remain in the possession of the Town for the duration of the test.
Test route(s) shall be developed by the Vendor that address the entire service area of the Town. All test routes will be approved by the Town of Cheshire. Required data shall be recorded at each grid throughout the test route. Transportation shall be provided by the Town to any test locations not generally accessible by car.
Successful completion of the BER test shall occur when 95 percent or more of the total grids yield a BER of 2% or less.
16.3.2 Delivered and/or Digital Audio Quality (DAQ) Testing
The Vendor shall perform a DAQ test to evaluate system talk out and talk-back. The test evaluation team must consist of a minimum of two Town representatives and one Vendor representative, who must be present to conduct this test.
In order to perform this test the service area shall be divided into uniformly sized grid squares with sides as determined in TIA/EIA/TSB88-C to yield a 95 percent or higher confidence level. The maximum allowable grid size shall be 0.25 miles on any side. A DAQ test shall be performed in each grid where a portion of that grid is within the service area. A test point within each grid will be selected by the Town, with the understanding that selected points shall not cluster adjacent grid test points together. All selected test points must be within the service area.
The testing instrumentation shall be configured to allow use both on foot and in a vehicle, and shall simulate a portable radio, worn at hip level for all grids covering any portion of the Town. The testing instrumentation shall be verified by an independent means acceptable to the Town of Cheshire both before and immediately following the test. Test equipment shall remain in the possession of Town.
Each test point may be evaluated from a fixed location or in a moving environment, at the Town of Cheshire’s discretion.
119 | Page RFP: Town of Cheshire Public Safety Communications System
The Town will provide test messages representing commonly used dispatch language for the Fire and Police Departments. The Vendor and the Town of Cheshire must mutually agree on the test messages. The test messages will be no longer than 10 seconds in length. Test messages will be drawn at random, read and evaluated.
If a majority of the evaluation team believes that the test message met a minimum DAQ of 3.4 on the first transmission, the grid passes.
If a test point is evaluated on-street utilizing the configured test instrumentation, and a majority of the evaluation team believes that test message did not meet a minimum DAQ of 3.4 on the first transmission, the grid fails.
If a test point is evaluated in-building utilizing a portable radio, and a majority of the evaluation team believes that the test message did not meet a minimum DAQ of 3.4, a building penetration loss level must be determined. The definition of DAQ 3.4 is listed in Table 4 below.
