Abstract

Wireless Local Loop (WLL) has become a viable alternative for the last mile problem, especially for emerging countries. However the success of a large scale deployment of such a technology relies on careful network planning taking into account existing building layout to achieve predictable quality of service (QoS) for each customer. This paper proposes an approach where actual geographical layout of the area to be covered is taken into account to distinguish line-of-sight (LOS), Obstructed Line-of-sight (OLOS) and non-LOS (NLOS) regions and uses adequate propagation models for each case. By doing so a more accurate prediction on achievable QoS is possible for each point of the area. The output of the tool is a point-by-point quantitative measure of received average signal strength prediction and an optimized overall coverage quality. Finally, field measurements and benchmarking were used to validate the approach adopted.
