Evaluating and mapping signal coverage requires accurately measuring and assessing signal strength and quality across diverse geographical locations and varying real-world conditions. A handheld spectrum analyzer combined with logging software enables field engineers to validate signal propagation patterns and identify sources of signal degradation or interference at specific frequencies and geographic locations using the drive test methodology.
Creating a signal coverage map requires RF measurement equipment with time-interval logging, geospatial mapping tools with GPS geotagging capabilities, and analysis software to correlate RF power levels with locations on a map. Capturing IQ data in addition to channel power enables post-drive analysis to pinpoint causes of signal degradation. Using geolocation data along with signal measurements enables network operators to enhance network infrastructure and performance, address coverage issues, and provide optimized quality of service for users.
