摘　　要：针对某运营商EGRPS网络在农村面对的困境和该运营商GSM900技术向UMTS900技术或LTE技术演进的必要性，分析7GSM900技术向UMTS900技术或LTE技术演进的频率规划，最后从覆盖、容量和网络改造三个方面分析了该运营商GSM900技术向UMTS900技术或LTE技术演进对现有GSM900网络影响。UMTS900和LTE允许的下行最大路径损耗比GSM900语音业务允许的最大路径损耗大3～4dB，部署UMTS900或者LTE系统后，可以提供的下行数据吞吐量是原有GSM900系统的4．38—20．18倍。According to the problems the operator faces in EGRPS network in rural area and the necessities the operator evolves from GSM900 to UMTS900 or LTE, frequency planning of the evolution from GSM900 to UMTS900 or LTE is analyzed, and finally the impact of the evolution from GSM900 to UMTS900 or LTE on current GSM900 network is given, including coverage, capacity and network transformation. Maximum path loss of UMTS900 and LTE downlink is 3-4dB more than that of GSM900 voice service, thus downlink data throughput can reach 4.38-20.18 times than that of GSM900 system after the deployment of UMTS900 or LTE system.
