GSM频段Refarming至LTE FDD策略分析与验证

GSM bands Refarming to LTE FDD strategic analysis and verification

当前移动用户数据业务呈现高速增长,GSM对比LTE频谱效率低,已不能满足用户高速数据需求,考虑到GSM网络利用率逐年下降,而将GSM部分频段用于建设LTE后能提供更高频谱效率及峰值速率来满足用户日益增长高速率需求。本文充分对比不同频段的LTE FDD网络性能,详细介绍了GSM频段Refarming(频率重耕)至LTE的带宽组网分析、策略分析及设备配置方案,并对相关测试结果进行了充分分析。

Current mobile users data services are growing fast,GSM’s spectrum effi ciency is lower than LTE andit can’t fufi ll users high-speed data requirements,also considering GSM network utilization decreasedyear by year,it can provide higher spectrum effi ciency and peak rate after using part of GSM bands intoLTE.Firstly,this paper fully compares with LTE FDD network performance of different bands.Secondly,it detailedly introduces the GSM bands refarming to LTE FDD onbandwidth network analysis,strategyanalysis and equipment confi guration.Finally,relevant test results are fully analyzed.
