AT&T Mobility

AT&T Mobility (or AT&T Wireless) is an American telecommunication company. For general information regarding AT&T, please check out Wikipedia page: AT&T.

Antenna

AT&T has multiple contracts with different manufacturers for antenna.

LTE Mapping Practices

Macro Tower

Macro towers are those structures designed for cellular, mobile radio, public safety and microwave operations. They are usually at high ground for good RF propagation.

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.

The estimated location of eNB does not necessarily mean the tower is at the nearby location. Due to terrain, weather, API and many other factors, the data may not be enough to precisely reflect the correct location. Deleting seemingly wrong eNBs with caution, as this may erase the data from other people.

Cell

Generally, 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.

Small Cell / MicroCell

A small cell is a radio access point with low radio frequency (RF) power output, footprint and range. It is operator-controlled, and can be deployed indoors or outdoors, and in licensed, shared or unlicensed spectrum.
