Field test of TD-LTE for transmitting the integrated services of urban rail guided transportation

WLANs are susceptible to interference and not suitable for transmission of the integrated services of urban rail guided transportation. With the rapid deployment of 4G, it is highly concerned if the LTE can be used for urban rail transit. In this paper, we present the latest field test we made on the performance of Time Division Long Term Evolution(TD-LTE) to transmit the integrated services of urban rail transportation. It is found the effects of train speed and handover on the packet loss rate, delay and throughput are minimal. The test result prove that the performance of TD-LTE at high speed satisfy the Quality of Service(QoS) requirements of integrated services of urban rail guided transit.
