Design-Build Services for the MBTA Critical Communications Implementation and P25 Plan for Transit Police - Rail and Bus (CCTRB) Project

The fundamental Project requirement is to design and upgrade the MBTA’s existing radio system to APCO P25 Phase 2 and build a robust, reliable radio system that will provide effective communications for all MBTA system users within the specified coverage area (i.e., radio above and below ground). The existing EDACS radio will be replaced with an integrated, state-of-theart wide area Land Mobile Radio-based voice and data network for system-wide use throughout the existing route 128 belt, as well as expanded out to the I-495 areas north, south, and west. The new system will utilize Project 25 Phase 2 trunked technology for voice and data communications. The CAD/AVL system and coverage will remain as existing. The MBTA maintains a tunnel radio communications system for underground areas of the MBTA system. These underground areas include rail tunnels, underground busways, underground station platforms, mezzanines, walkways, hallways, equipment rooms, and other underground areas patrolled by the MBTA Transit Police. These underground areas present challenges for the transmission of radio signals because of losses through the materials of construction, signal interference, and dead spots in geometrically complex areas, among other factors. This Project will improve the capacity, range, and efficiency of the tunnel radio communications system. The improved system will provide over 1,200 trunked talkgroups, as well as a signal level of -90 Dbm or better within any vehicle in a tunnel, and will have a coverage probability of 90% at any point in the system. The signal levels and coverage will require extensive testing and verification.
