Communicating Beneath the Streets of San Francisco.Business Editors ORLAND PARK Or·land Park A village of northeast Illinois, a residential and manufacturing suburb of Chicago. Population: 53,300. , Ill.--(BUSINESS WIRE)--June 29, 2000 -- Andrew Corporation's distributed communications products enable communications in BART's new Tunnel Communications Extension System -- San Francisco's BART (Bay Area Rapid Transit “BART” redirects here. For other uses of "BART" or "Bart", see Bart. The San Francisco Bay Area Rapid Transit District (BART) is a heavy rail public rapid-transit system serving the San Francisco Bay Area. ) is now operating its new Tunnel Communications Extension (TCE TCE trichloroethylene. TCE Environment A volatile chlorinated hydrocarbon that boils at 88ºC and is highly soluble–1000 ppm in water, with various industrial uses Toxicity Peripheral neuropathy, carcinogenic. ) system. The new system provides trunked radio communications for vital services throughout the underground portion of the BART. These services include essential communications for train operations, emergency crews, maintenance, administrative staff and police. The TCE system was designed, built, and commissioned by Andrew Corporation's Distributed Communications Systems division. The TCE system uses over 50 miles of RADIAX(R) RCT RCT Randomized Controlled Trial RCT Regimental Combat Team (infantry regiment with their own artillery, engineers, medical and tanks) RCT Rollercoaster Tycoon RCT Randomized Clinical Trial RCT Rhondda Cynon Taff Series radiating coaxial cables to provide coverage throughout the BART tunnel system and underground concourses and platforms. Distribution of the trunked radio signals within the tunnels is achieved with 75 major nodes used for interface and amplification of the signal. A typical node consists of dual redundant bi-directional amplifiers and an interface-switching unit to control the signal feed direction for the adjoining tunnel segments. The underground communications system provides seamless coverage throughout the tunnels and interfaces with the above ground trunked radio system A trunked radio system is a complex type of radio system that is used to maximize available capacity in a two-way radio system, usually UHF. Groups of users are given a logical talkgroup to share for their communications, rather than a dedicated radio frequency. . Redundancy features of the system such as dual bi-directional amplifiers at each node ensure a high degree of reliability for the essential communication services. Andrew also provided comprehensive remote status monitoring and control of all equipment nodes that is capable of being accessed over standard telephone lines. BART officials have indicated a high degree of satisfaction with the performance of the system as installed by Andrew and with the degree of professionalism shown by the company. Under a separate contract, Andrew is providing design, equipment, installation support, and commissioning of an additional network that will connect the existing BART system to the San Francisco International Airport “SFO” redirects here.
