AI Technical Summary

Problems solved by technology

However, GSM-R is a narrowband communication system with low spectrum utilization, which is difficult to meet the development needs of railway broadband data services in the future; on the other hand, with the development of public mobile communication networks from 2G and 3G to 4G, the GSM market is gradually shrinking. GSM-R will lose the support of the equipment industry chain
