摘要
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。
With the issue of commercial licences for 4G, large-scale commercial application of LTE is beginning in China. But site resources is becoming scarcer with the development of the city. The difficulties on obtaining sites will 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.
