Montreal Transport Agency Selects PowerTrunk TETRA Network
Wednesday, May 17, 2017 | Comments

The Société de transport de Montréal (STM) selected the S.M. Group International (SMi), Télécommunications Grimard and PowerTrunk, part of the Sepura Group, to supply and install a new, state of the art TETRA radio and voice recording system for its subway operations across its network. SMi and Grimard will provide the installation and system integration services, while PowerTrunk will supply the TETRA network infrastructure and radio dispatch solution.

The STM's new TETRA network will serve its entire transit network and support all operations-related communications between the control center, train operators and all surface or underground personnel. The technology will also provide the STM’s security service and operations personnel with a cutting-edge communications system.

The new network, composed of more than 120 TETRA 800 MHz base stations, will ensure underground radio coverage throughout all four subway lines, as well as across all 68 of its subway stations. The new technology will also ensure above-ground coverage across the entire territory of the Greater Montreal area, including other areas where the STM is active, such as sections of the cities of Laval and Longueuil.

To properly support all network operations, the system will be comprised of more than 50 dispatcher stations, a voice recording system and a new control center with an interface that will be directly integrated to STM’s existing centralized command system. Once fully deployed, the STM’s network will become the biggest TETRA infrastructure in North America.

The STM subway system is Canada's largest and busiest underground transit system and North America's third busiest, behind New York City’s and Mexico City’s public transit networks. Montreal’s public transportation agency has been active for more than 150 years and remains at the cutting edge of technology, in an effort to provide users with fast, reliable and economical transportation services. In order to maintain this goal, the STM relies on a state of the art communications system across its entire network.
