Query: Improved propagation models for lte path loss prediction in urban &
  suburban Ghana   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.
