Abstract
As a train operation control information channel, GSM-R ( GSM for Railway) network should be highly reliable and safe and its wireless system network scheme is the key in GSM-R system planning. Based on the comparison between the co-located double-site and single network intertwined for GSM-R wireless networking, this paper analyzes and compares the wireless system networking scheme in terms of the networking complexity, reliability, frequency-planning and network optimization, network construction cost, and conducts mathematical analysis of the two schemes based on reliable mathematical modeling. The comparison results show that the more redundant of the system, the more reliable of the system, but comprehensive considerations are required in practical engineering. Relevant suggestions for the construction of future large-scale GSM-R renovation project are put forward.关键词
