Radio coverage shrinkage is one of the key factors that places limitation on link data transmission rate quality in mobile broadband networks, especially on users at cell edge. This occurs due to multipath radio signal fading, frequent changes in radio propagation conditions and base station equipment deterioration. Other key limiting factors includes intercellular/intracellular interference and random background noise in the network environment. Within this context, the importance of carrying out a routine independent assessments of deployed mobile communication networks in a realistic environment has also increased. This is to evaluate their robustness and performance capability in different radio propagation scenarios from one location to the other. This research work deals with practical performance monitoring and evaluation of deployed commercial mobile broadband HSPA networks, considering the radio coverage and service quality aspects in typical suburban environments. The aim is to correlate cell coverage with radio link quality performance indicators in different propagation environments. The aim have been accomplished by carrying out field test measurement campaign and a drill down post data analysis on the HSPA networks and this enable us to critically examined and relate vital QoS parameters at the cell site specific level. Finally, based on Block Error rate performance threshold, the cell radius has been estimated for each measurement routes. The results could form the basis for performance optimisation of mobile cellular networks.
