In-building cellular specialist SOLiD said that it has been chosen by neutral-host provider BAI Communications? to use its GENESIS Distributed Antenna System (DAS) as part of the project to deliver high-speed mobile connectivity across the London Underground.
Transport for London (TfL) is a U.K. government agency that manages London?s public transport network. Its Telecommunications Commercialization Project (TCP) will provide cellular connectivity in the Underground?s tunnels and stations where service has been non-existent. TfL established Wi-Fi in 270 stations and now is targeting full mobile access in its 400 km of tunnels and within all stations and platforms that are underground, SOLiD said.
?BAI?s partnership with TfL will establish a long-awaited connectivity backbone with a city-wide integrated communications network delivering multi-carrier cellular, Wi-Fi, and fiber connectivity services. Building on the success of previous project collaboration work, such as the New York City subway, BAI will deploy in the London Underground SOLiD?s groundbreaking GENESIS DAS that provides seamless cellular communications in hard-to-serve areas. To meet the project?s challenging environmental, space, and reliability requirements, SOLiD will provide project-fit customization of the GENESIS DAS solution,? the firm said in a release.
TfL?s earlier pilot for 4G coverage, which began in March 2020 and covered most of the tunnels and stations between Westminster and Canning Town along the Jubilee line, used SOLiD?s GENESIS DAS solution. Customers? phones automatically search for the mobile signals emitted by the DAS, achieving continuous connectivity as if above ground, SOLiD added.
