Context changes the reading
A low RSRP sample says little on its own. A route view shows whether it belongs to one short passage, a repeated weak segment, or a gap in the source measurements.
Use time and position together when reviewing handovers and quality changes. Keep GPS gaps visible; drawing an uninterrupted line through missing coordinates can suggest certainty that the source data does not support.
From observation to action
Start with an anomaly in the chart, locate its route segment, inspect the serving cell and events, then document the evidence and remaining uncertainty. The map is spatial context, not an area-coverage survey.
