Checking Coverage Area of Best Cell
Checking Pollution
Dominance
Polluting cells are defined as cells whose average RSRP is within a user-specified dB range of the best cell's average RSRP.
For example, example, if the best best cell has an average average RSRP RSRP of -50 dBm and the range is set to 10 dB, the raster would show how many cells in each bin have a mean mean RSRP RSRP between between -50 dBm dBm and -60 dBm. dBm.

Cross Feeder
Average Line
Cross Feeder Full Match: Match: The cell's recorded azimuth is within approximately 60° of its calculated azimuth, and no other cells have a recorded azimuth closer to the calculated azimuth. Partial Match: Match: The cell's recorded azimuth is not close to its calculated azimuth, and another cell's recorded azimuth is closer. However, this is not a crossed feeder issue as there is not a reciprocal relationship between these cells. Rotated: Several cells on the same site have the wrong feeder cable. For example, Rotated: Cell A has Cell B's feeder, Cell B has Cell C's, and Cell C has Cell A's. Swapped: The feeder cable for this cell has likely been swapped with that of the Swapped: XServer.. Geo classifies two cells as Swapped when each has a recorded azimuth XServer that is closer to the other's calculated azimuth.
