摘要
LTE网络建设中遇到了一些挑战,包括上下行不平衡、基站天线成本和安装难度大、与3G基站覆盖不同步等。针对这些情况,本文提出了使用塔顶放大器的方案提高基站上行接收灵敏度,从理论上分析了塔顶放大器对于提升覆盖能力的效果,并总结了塔顶放大器在LTE网络建设中的应用场景。
LTE network construction encountered a number of challenges, including unbalanced and down the line, the cost of the base station and antenna installation is difficult, and 3G base station coverage is not synchronization. For these cases, the proposed scheme to improve the use of tower mounted amplifier uplink station receiver sensitivity. And, from the theoretical analysis of the tower mounted amplifier for enhancing the coverage of the effects, and summed up the tower mounted amplifier in the LTE network construction application scenarios.
