Finding the right radio system for the largest transit system in North America
The radio technology needed by NYCT had to be an open standard with enough scalability and efficiency to carry the voice and data communications of 5,700+ buses and 1,500+ support staff operating in 29+ bus facilities. The radio system had to provide the capability to transport call signaling data, AVL, and voice traffic for every bus reliably. Communication with the buses must be robustly supported by the radio infrastructure, ensuring system availability and maximum coverage of the bus routes that compose the service area.
Lastly, the end-user equipment must be dual-band and spectrally efficient, capable of working in 700MHz and 800MHz, with the ability to operate with other radio technologies, fundamentally P25, in critical situations where interoperability is required in frequencies allocated for public safety use.
New York City Transit Authority released a RFP that concluded in February 2016 with the award to Parsons Transportation Group of New York, Inc. of a PowerTrunk TETRA voice and data infrastructure, Command and Control CAD Solution, and thousands of radio terminals. The NYCT BRS project is meant to be the largest TETRA network in the United States by number of subscribers.
