论文摘要
为了最大程度地提高LTE蜂窝网络的好处，需要仔细和适当的计划。这需要使用准确的繁殖模型来量化基站部署所需的路径损失。加纳部署的LTE网络几乎无法满足所需的100Mbps吞吐量，从而导致客户不满。网络运营商依赖于为广义环境设计的传输计划工具，这些工具与已嵌入的繁殖模型相关，适合其他环境。因此，对加纳传输网络计划者的挑战将是选择最适合加纳环境的准确而精确的传播模型。鉴于此，在加纳选定的城市和郊区环境中进行了800MHz和2600MHz的广泛LTE路径损失测量值，并与6种常用的传播模型进行了比较。与常用的传播模型相比，这项研究中开发的Ericson，SUI和ECC-33的改进版本更准确地预测了加纳环境中的路径损失。
To maximize the benefits of LTE cellular networks, careful and proper planning is needed. This requires the use of accurate propagation models to quantify the path loss required for base station deployment. Deployed LTE networks in Ghana can barely meet the desired 100Mbps throughput leading to customer dissatisfaction. Network operators rely on transmission planning tools designed for generalized environments that come with already embedded propagation models suited to other environments. A challenge therefore to Ghanaian transmission Network planners will be choosing an accurate and precise propagation model that best suits the Ghanaian environment. Given this, extensive LTE path loss measurements at 800MHz and 2600MHz were taken in selected urban and suburban environments in Ghana and compared with 6 commonly used propagation models. Improved versions of the Ericson, SUI, and ECC-33 developed in this study predict more precisely the path loss in Ghanaian environments compared with commonly used propagation models.
