Executive Summary

Wireless link quality is closely related to the received signal strength. Hence, transmit power control can be used to adjust the communication link quality to avoid asymmetric or weak links. This paper proposes a spatial radio resource model for Quality of Service (QoS) reliability in General Packet Radio Service (GPRS) networks. To model the propagation parameters, the authors adopt the empirical modeling approach by measuring signal outages at various base stations from a well established network, operating in Nigeria. They collect these data over a period of three months and apply the resultant data as parameters to the proposed model. They simulate the model under ideal conditions and evaluate the system's performance as well as the power control trade-off.
