regional focus
Beijing Metro’s Changping Line, whose second phase is due to be completed this year, is one of six new lines built for the Chinese capital region. TETRA radio equipment has been provided by Motorola, but the system integrator responsible for the project is Radio Frequency Systems (RFS), which has supplied radiating cable installations for the tunnel sections
Hong Kong Police followed, adopting the TETRA Dimetra
Having supplied a system for the 2008 Olympic Games in Beijing (pictured below), Cassidian (formerly EADS Defence & Security) followed up with
an 800MHz system for the municipality of Guangzhou. This later provided support for the 16th Asian Games, the world’s second biggest sporting event after the Olympics. Some 2·2 million radio calls were made on the event’s opening day
IP system in 2003–4, with (at the time) three master switches, one for each police region – Hong Kong Island, Kowloon and New Territories, connected together to control approximately 100 cell sites. More than 10000 radio terminals were provided in the initial phases for beat officers, police vehicles and motorcycles; 90 per cent of these were MTP750 handhelds. More recently, in Ho Chi Minh City, Vietnam, the
company deployed Phase One of the country’s first wide-area TETRA digital trunked radio communications system for the Ministry of Public Security of Vietnam (VMOPS) – effectively the police services. For a technically challenging project in 2003, Taiwan’s High
Speed Rail Corporation selected Motorola’s Dimetra TETRA system to serve its entire 345 kilometres of track, including tunnels, stations and depots, and to operate on trains travelling at over 300 km/h. Main contractor for the project, which was claimed to be the world’s first TETRA solution for the high- speed rail industry, was Toshiba Corporation.
Aviation In early 2008, the Hong Kong Airport Authority selected a Motorola Dimetra IP TETRA system for Hong Kong International Airport (HKIA), to “enhance the efficiency of radio communications for airport operations” as rising
passenger numbers placed heavier demands on the airport’s existing analogue system. Te three-site TETRA network provides seamless communications and full interoperability among users in airport operations such as security, operations, maintenance, baggage handling and other ground services. Motorola’s solution supports simultaneous voice and data messaging, multi-slot packet data, telephone interconnect, voice logging and encryption. At about the same time, South Korea’s national and largest
airline, Korean Air, replaced an analogue radio system at its main hub with a digital TETRA-based private network – in the words of Lee Hyogeun, general manager of the airline’s IT department, to “enable us to implement new working practices on a secure and ultra-reliable framework”. Te airline had spent nearly three years seeking and evaluating communication technology to meet its needs before settling on a Motorola solution. Today the network serves over 4000 employees using MTP850 TETRA portables, customized with Korean language keypads, and it is expected that remaining smaller airports will be brought on to the network in due course. In Singapore, Singapore Prison Services took on the first
TETRA system for a public safety agency in the country. Phase One was fully operational by the end of 2004. In the following year, Motorola TETRA equipment worth US$5.4 million was commissioned at the PSA Singapore Terminal, the world’s largest trans-shipment container hub) to replace disparate analogue radio systems with an integrated digital platform. Other TETRA successes for Motorola in the region have
included na TETRA system in Shanghai to support the 9th Special Olympics in 2007: from more than 150 sites across the city, four trunked networks delivered service to over 10000 users.
nsystems for the Beijing Urban Transit Railway Corporation. Underlining the popularity of using TETRA in the region’s public transport, the Beijing municipal authority’s four light rail lines built before the 2008 Olympics are all equipped with mutually interoperable TETRA communications systems.
