LTE网络建设中微基站的应用探讨

摘要

针对密集城区中传统宏基站组网的覆盖深度不足的问题，介绍了微基站的特点和微基站在深度覆盖方面的优势，给出了微基站在室外覆盖和室内覆盖的应用策略和建议，针对微基站这种高度集成化基站所带来的供电需求、传输光纤需求的挑战，均给出了相应的解决方案，对于微基站引入后的网络优化进一步复杂化也作了分析，最后将微基站组网和宏站组网的投资做了比较详细的对比，证明了微基站应用于LT E组网对于节约投资的重大意义。%Targeting the coverage depth insufficiency problem of traditional macro base station networking in densely populated urban areas, this paper introduced micro-base station’s characteristics and its advantages in coverage depth, advised on its application strategy for both outdoor and indoor coverage, proposed respective solutions for the challenges it brought with itself in power demand and transmission ifber demand, for it was such a highly integrated base station. The paper then analyzed the more complicated network optimization after the introduction of the micro base station, ifnally compared macro base station networking’s detailed investment with the micro ones, proving the ifnancial signiifcance of micro base station application in LTE network.
