SALIENT CHARACTERISTICS.pdf

This document is a technical specification document for P25 Digital Vehicular Repeater Systems (DVRS) used in federal contracting procurement activities.

The Government requires acquisition of P25 Digital Vehicular Repeater Systems, with the baseline specification defined as the Futurecom Systems Group DVR LX UHF Digital Vehicular Repeater System or functionally equivalent products. Offerors proposing equal products must demonstrate compliance with mandatory salient characteristics including: mobile system integration with existing P25 mobile subscriber units (Motorola APX Series) operating through the mobile radio's control head interface without requiring external control heads; frequency and power output capability in the UHF band (380–406 MHz, 406.1–512 MHz) with programmable RF output from 1 to 10 Watts continuous duty, supporting Full Duplex, Simplex, In-Band, and Cross-Band configurations; P25 feature pass-through transparency for Portable Push-to-Talk ID, Emergency Alarm and Call IDs, System Network Tones, and end-to-end P25 hardware encryption without signal decryption/re-encryption at the repeater; local repeat and on-scene coordination capabilities; automated co-located scene interference mitigation; and capacity supporting a minimum of 192 programmable repeater channels with an MSU table of at least 2,047 entries. Electrical specifications require 13.8V DC ± 20% operating voltage with maximum transmit current draw of 5.0A at 10W RF output. The technical justification emphasizes system interoperability and mission safety with the agency's existing ASTRO 25 P25 Land Mobile Radio network, physical integration and fleet uniformity with existing vehicle installations, and prevention of safety risks during critical incidents.
