How It Works
Below is a schematic of the design of the Transit Wireless solution.
Wireless carriers who have contracted with Transit Wireless to provide voice and data service to their customers in underground New York City subway stations co-locate their Base Stations with Transit Wireless’ Optical distribution equipment at a Transit Wireless Base Station Hotel, which is a resilient, fault-tolerant commercial facility with redundant air-conditioning and power.
Base Stations are provided by wireless carriers for each band and technology; 700-LTE, 850-Cellular, 1900-PCS, 2100-AWS and other. These Base Stations connect to Transit Wireless’ Radio Interface and Optical Distribution System in the Base Station Hotel. Radio signals are combined, converted to optical signals and distributed on Transit Wireless’ fiber optic cable through ducts under city streets to subway stations where the optical cables connect to multi-band Remote Fiber Nodes.
Remote Fiber Nodes are located on every platform, mezzanine and at various points within public access passageways. Coaxial cable is connected to each Remote Fiber Node and extends signals to strategically located antennas throughout each subway station. Utilizing this approach, low-level radio signals are evenly distributed providing seamless coverage from above ground to underground stations.
A Network Management System monitors the service; detects problems and provides alerts so technicians can be dispatched if needed.
