As we all know, the working surrounding for the gas pipeline is dangerous, so the user cares about the system safety at most, therefore the explosion-proof IIC 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:
1 > 95% coverage, > 99% onetime call termination rate.
2 Interconnection between the TRS with PSTN/PABX: the radio under the vehicle should call to the radio under each Base Station through the voice exchange network.
3 Can use conventional radios under Trunk system.
4 Take future expansion into account and be ready to upgrade into Digital era.
5 Turnkey project, calls for comprehensive engineering capability.
6 Data application: besides the basic voice dispatching, the SMS and status message function is also needed.
