China - Asia Gas Pipeline

Hytera Trunking Solution facilitates the China-Asia Gas Pipeline.


The China-Asia Gas Pipeline, the longest natural gas pipeline all over the world, which is from the border ofTurkmenistan and Uzbekistan, through central Uzbekistan and southern Kazakhstan, then enters into China.The total length of the pipeline is more than 10,000 kilometers. Annually stable transfer about 300 billion cubic meters natural gas to China, which is equal to half of China's domestic natural gas production in 2007.

China National Petroleum Corporation had invested more than 7 billion USO to construct this pipeline.The pipeline has important strategic significance for Chinese government and economic development. In order to ensure the project run well, a comprehensive solution was needed, including the GSM  solution, the GE compressor solution, video monitor solution, TRS(Trunk Radio System) solution and many other solutions. Hytera took part in this project as the subcontractor ofTrunk Radio System provider.

Customer Demands

System safety at most, therefore the explosion-proof llC class radio is necessary and its output power must be lower than 1W. Also the comprehensive dispatching and management function is in need; the detailed customer requirements are as below:


  • > 95% coverage,> 99% onetime call termination rate.
  • Interconnection between the TRS with PSTN/PABX: the radio under the vehicle should call to the rad under each Base Station through the voice exchange network.
  • Can use conventional radios under Trunk system.
  • Take future expansion into account and be ready to upgrade into Digital era. Turnkey project, calls for comprehensive engineering capability.
  • Data application: besides the basic voice dispatching, the SMS and status message function is also needed.
