Research on Service Capability of Vehicle-to-Ground Communication System Carrying PIS and CCTV Based on LTE

Abstract

With the continuous development of urban rail transit, people’s demand for business services is diversified. Passenger Information System (PIS) and Closed Circuit Television System (CCTV) are the main businesses among them. Design Urban Rail Transit Based on Long Term Evolution (LTE) Technology Vehicle-to-Ground Wireless Communication System, Test the Capacity of Vehicle-to-Ground Communication System to Carry PIS and CCTV under Certain Bandwidth, and Carry out Field Test on Qingdao Metro 2. The test results show that under the bandwidth of 5MHz, 10MHz and 15MHz, LTE network can carry one PIS multicast service of 2M, 4M and 6M PIS video multicast service and channel1, channel 2 and channel 3 of CCTV video upload service respectively, with good transmission service quality. The research has certain reference value for PIS and CCTV service code rate design and route planning.
