Coverage analysis: RSRP/SINR map interpretation

Reading RSRP Coverage Maps

Coverage maps are the primary deliverable of every drive test. RSRP maps use a standard color scale: dark green (above -80 dBm, excellent), light green (-80 to -95, good), yellow (-95 to -105, marginal), orange (-105 to -110, weak), red (below -110, poor). When analyzing a map, look for continuous coverage along the route — transitions should be gradual as you move between cells. Abrupt drops from green to red indicate coverage holes, typically caused by terrain blockage, building obstruction, or sectors pointing away from the road. Isolated red patches along highways are critical issues for…
