Cassidian, an EADS company, recently won a contract to expand the metro coverage of Beijing Government Shared Radio Network. The expansion will improve the network coverage and provide communication and services for the Beijing metro police to ensure the security of metro’s operations.
Cassidian will provide 24 TB3 base stations to expand the coverage of the new Beijing metro lines: Line 14, Line7; west line of Line15; extension of Line 8; and the connection between Line 8 and the Changping Line. The delivery and implementation of the new communications system will take place in 2013 and 2014. On completion of the new lines, all the 17 operational metro lines will be equipped with Cassidian’s TETRA system.
The Beijing Government Shared Radio Network, also called ‘Beijing JustTop TETRA Network’ is provided by Cassidian. It is the largest digital trunked network in Asia and the biggest citywide TETRA network in the world, covering Beijing city area, all the venues, all the metro lines, counties, the main highways and important buildings. The network infrastructure includes 350 base stations, which serve about 90,000 subscribers.
The Beijing metro delivered over 2.18 billion rides in 2011 and on 28April 2012 set a single-day ridership record of 8.59 million. Nevertheless, the existing metro network still cannot adequately meet the city's mass transit needs and extensive expansion plans call for 19 lines and over 708km of track to be in operation by 2015 and 1,050km of track by 2020.
