随着4G牌照的发放，国内LTE即将开始大规模商用，但随着城市的发展，站址资源越来越稀缺，站址获取的困难势必要求无线网络覆盖技术进一步提升。为了应对站址资源获取的困难，从技术层面扩大基站覆盖范围，在实测的基础上，对LTE设备的2T4R的应用效果以及成本效益进行了分析，并根据2T4R的优缺点给出使用场景的建议。
隨著4G牌照的髮放，國內LTE即將開始大規模商用，但隨著城市的髮展，站阯資源越來越稀缺，站阯穫取的睏難勢必要求無線網絡覆蓋技術進一步提升。為瞭應對站阯資源穫取的睏難，從技術層麵擴大基站覆蓋範圍，在實測的基礎上，對LTE設備的2T4R的應用效果以及成本效益進行瞭分析，併根據2T4R的優缺點給齣使用場景的建議。

With the issue of commercial licences for 4G, large-scale commercial application of LTE is beginning in China. But site resourc-es is becoming scarcer with the development of the city. The difficulties on obtaining sites wil require to further improve the wireless network coverage technology. In order to deal with the difficulty on obtaining site resources, it need to expand the coverage of base station. It gives us the usage scenarios for 2T4R based on the advantages and disadvantages through the analysis of the application effect of LTE device 2T4R and cost benefit.
