58 -- WIRELESS RADIOS TESTING DUE 013196 POC Elaine Glynn, Contracting Officer, (202)435-6940, Jim Downes, Technical Information, (202)622-1582 58 - REQUEST FOR VENDOR PARTICIPATION, The United States Secret Service, on behalf of the Federal Law Enforcement Wireless Users Group (FLEWUG), is seeking vendor equipment and participation, via a no cost bailment type agreement, to test narrowband (12.5 kHz channel bandwidth) digital radio systems in an operational environment. The pilot project, with joint participation of member agencies of the FLEWUG and various state and/or local government organizations, will evaluate and test VHF (150-174 MHz) and UHF (406-470 MHz) conventional (non-trunking) equipment utilizing narrowband digital technology with the Improved Multi Band Excited (IMBE) Vocoder as recommended in TIA/EIA Interim Standard (IS) 102.BABA (Vocoder Description) and the Common Air Interface (CAI) as specified in TIA/EIA Telecommunications System Bulletins (TSB) 102.BAAA (Common Air Interface) through TSB102.BAAD (CAI Operational Description for Conventional Channels) and proposed interim Federal Standards (FED-STD) 1102 and 1106. The test program, which will be conducted at specific locations to be determined, will evaluate proof of operational concepts and interoperability capabilities. The program, which will last approximately one year, is envisioned to consist of an undetermined number of base stations/repeaters and subscriber (mobile and portable) units from multiple vendors. Prototype and engineering models will be acceptable for this pilot program. During the pilot test period equipment and operational concepts will be evaluated to determine the feasibility of future programs. Manufacturers participating in the evaluation will be free to make changes in their equipment as upgrades become available. The program manager(s) will provide periodic reports to the participants identifying technology shortfalls and suggested resolutions relating to the open architecture of the system. An ''after- action'' report will be prepared and provided to all participants. Results of the test will not be used for evaluation or basis for qualification in future procurement actions. Participation or nonparticipation will not be a consderation in future competitive procurement actions. Letters from manufacturers stating their intent to participate will be accepted through January 31, 1996. All requests for participation shall be in writing. The government reserves the right to limit the number of participants in the test(s). Any questions and/or concerns of the manufacturers should be addressed in the letter. The government will host a meeting of all intended participants to discuss the pilot program(s) in more detail at a time and location to be determined, but no later than March 1, 1996. Draft copies of the Memorandum of Agreement (MOA) will be provided on request to those parties submitting a letter of intent. (0340)
