LTE Mapping practices

eNB

eNB IDs vary by region. Under the OpenSteetMap basemap, AT&T divides the whole country into various regions (e.g., AT&T Mid-Atlantic, AT&T South). It is common that adjacent counties of the same state will use completely different conventions.

Cell

Genrally, AT&T strictly follows such convention on cell ID numbering (3 sectors):

  • Band 5: 1, 2, 3
  • Band 2: 8, 9, 10; 179, 180, 181; 208, 209, 210
  • Band 41/66: 22, 23, 24; 222, 223, 224
  • Band 12/171: 15, 16, 17;
  • Band 30: 149, 150, 151;
  • Band 142: 193, 194, 195; 215, 216, 217;

1: Old band plan, recent cellphones will display the other band.

2: In areas without band 12 spectrum license, ATT may directly use cell 15, 16, 17 for band 14 (e.g., West Virginia, Nebraska).

If the cell tower has more than 3 sectors while only using 1 eNB, the naming pattern may be a little bit different. For example: 8, 9, 10, 11 for band 2.

Band 29 and Band 46 cannot be associated with eNB but still can be recognized by the App.
