LTE-FDD与2G/3G系统共天馈的可行性分析

摘要

With the release of 4G licenses of LTE-FDD, the construction of network and base-stations come one after another. After the analysis of advantages and defects of setting up a new base-station, three alternative modes of co-location scenarios between LTE-FDD system and 2G/3G system are proposed, based on the spectrum occupancy of present networks of China Unicom and China Telecom. The analysis on feasibility of the three alternative modes provides the experience reference for 4G network construction of operators.%随着4G LTE-FDD牌照的正式发放,LTE-FDD的建网建站问题接踵而至.文章在对4G基站独立建设的利弊进行了简要分析之后,结合联通和电信两大运营商现网频谱占用情况,对4G LTE-FDD与2G/3G共天馈建设提出了3种备选方式,并分别进行了可行性分析,为运营商的4G网络建设提供了借鉴.
