Data collected is stored in the log files and are further evaluated on RF logs post-processing tools which usually have GIS-based visualization capabilities.
RF drive test tools are also used to check coverage criteria of the installed cell towers and to evaluate if the cell tower sectors are providing the intended area of coverage as designed by Telcos. So, drive test in telecom is the best possible solution for mobile network operators (CSPs) to collect signal strength, mobile network latency, voice call KPIs etc along with GPS coordinates and constantly improve the network. Though it is true to some extent, drive test in telecom still remains the core of the network evaluation process to evaluate how the user experience the network environment continuously. New-age modern network simulation techniques made it possible for network engineers to create a mathematical model to evaluate network performance.
Drive testing captures accurate real-world data of the RF environment when placed under a certain set of environmental and network conditions. Assessing the Quality of Experience (QoE) of 3G, 4G, and 5G mobile networks in a specific area by measuring throughput, network coverage, bandwidth, is of paramount importance to ensure a high user quality experience on the network.
