Frequently Asked Questions About Cell Towers in Illinois
How many cell phone towers are there in Illinois?
According to the FCC Antenna Structure Registration (ASR) database, there are 694 registered cellular towers in Illinois. The map on this page pulls live from the FCC service, so the count reflects the most recent filings — typically within 30–60 days of changes being filed with the Commission.
Who owns the most cell towers in Illinois?
The largest licensee in Illinois is AT&T Mobility Spectrum, which is the FCC-registered owner of 219 towers in the state. The next largest is Cellco Partnership with 166 towers. Remember that an FCC licensee is not always the consumer-facing carrier — many sites are owned by tower companies (American Tower, Crown Castle, SBA Communications) and leased to multiple carriers.
Which county in Illinois has the most cell towers?
Cook County has the most registered cellular towers in Illinois with 26 towers. See the full county breakdown above for the top 10.
How tall are the cell towers in Illinois?
The average tower height in Illinois is 72 m (about 236 ft), and the tallest registered structure reaches 153 m (about 502 ft). The FCC ASR records structure heights in metres; we show metres alongside the imperial conversion. Heights are overall structure heights above ground level, including antennas and appurtenances, and exclude towers below the ASR registration threshold.
Can I download a list of cell towers in Illinois?
Yes. Enable the “Select towers within N miles” tool on the map above, click anywhere to set a center point, and the map will highlight every tower inside that radius. Then use Export CSV or Export GeoJSON to download the selection for use in a spreadsheet, GIS, or Google Earth. All data comes straight from the FCC ASR and is free to use.
Does this map show 5G small cells in Illinois?
No. The FCC Antenna Structure Registration system tracks structures over 200 ft tall or sites near airports. Small cells, DAS nodes, and rooftop antennas below that threshold do not require ASR registration and therefore do not appear on the map. The 694 towers shown are the macro cell sites that back-haul most cellular traffic in Illinois.
