Abstract: Quality of Service (QoS) represents the quality measure in cellular service to users to provide an error free service with defined voice quality, minimum acceptable signal strength, limited call blocking and dropping probability even at high data transmission rates. RF Analysis and Optimization are important processes to attain Quality of Service, which are carried out by using Drive-test tool. RF performance parameters such as the received signal strength at user and Ratio of the necessary signal (data) to the interference present in the atmosphere are defined in this paper, for the efficient and effective functioning of the RF network of different service providers in a given service test area. We have also measured short-call and long-call control tests from the drive testing process to facilitate analysis of call success rate, blocked calls and dropped calls. Our analysis of the drive test results has helped us in identify problems like fewer throughputs, drop calls, handover failures in a service test area for different service providers.
Keywords: QoS, Call Success Rate, Call Dropping Rate, Call Blocking Rate, CQI.
