Select a completed study and its map draws on the canvas, with the settings it was run with on the right. The "View" controls at the bottom of the left rail decide how you read it — and this is where the planning decisions actually get made.
Two ways to look at it
"Signal" is the coverage map you expect: predicted signal in every cell.
"Area served" answers a different question — for each block, how much of it is served. Take its caveat literally, because it's printed right on the control: "Not a signal level, and not a count of premises." Set the block size to suit the scale you're planning at, and use "Show classes" to hide the bands you don't care about.
The reliability slider — read this one carefully
Signal varies from spot to spot inside a single cell. "Location reliability" decides how conservative the map is about that, and it changes what you're looking at completely.
At 50% the caption reads "Median prediction — half of positions within a cell do better." That's the typical value — which also means half the positions do worse.
At 90%, 95%, or 99%, you're looking at the level you can actually count on at that share of positions. A promise rather than an average.
Turn it up and the coverage shrinks. That's the point: a map that looks strong at 50% and falls apart at 95% is telling you where your plan is thin.
Get exact numbers at a spot
Click "Inspect", then click the map. You get the typical signal at that point, how much it varies locally, the value at your current reliability setting, and which service class it falls into.

Tick "Tower & sector wedges" to draw the towers and which way each sector points on top of the coverage.
