Driving testing is a method of measuring and assessing the coverage, capacity, and quality of services (QOS) of a mobile network. Drive testing provides a live RF environment under a particular set of network and environmental conditions. The main benefit of drive testing is that it measures the actual network coverage and performance that a tester on the actual drive route would experience. Before starting Drive testing a good tester need to follow some basic things i.e, check weather required chargers, SIM cards, data cables, FT strips, extra batteries, earphones, SD cards, laptops with required software installed and car inverter are working properly or not. These equipments is always available with marquistech as per client requirements. Phone-based drive test systems are useful for evaluating basic network performance and are essential to characterizing the end-user experience while using the network. Phone-based systems address the need to verify network settings such as cell selection and re-selection boundaries and to measure the voice and data application performance in the live network. Most modern mobile phones chipsets have engineering measurement capabilities built into them, which were used during the mobile phone’s design process. These same parameters are exploited in drive test software to provide new value to the test engineers rolling out the final network.
