== LTE Mapping practices ==
=== eNB ===
eNB IDs vary by region. Under the [[wikipedia:OpenSteetMap|OpenSteetMap]] basemap, AT&T divides the whole country into various regions (e.g., [https://midatlanticregion.att.com/ AT&T Mid-Atlantic], [https://southregion.att.com/ 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 4<sup>1</sup>/'''66''': 22, 23, 24; 222, 223, 224
* Band '''12'''/17<sup>1</sup>: 15, 16, 17;
* Band '''30''': 149, 150, 151;
* Band '''14'''<sup>2</sup>: 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.
