Carriers in Cook
Number of towers and sites in the county where each carrier has been seen.
Good to know
Is the company that owns a tower my carrier?
Usually not. Most towers are owned by tower companies such as American Tower, Crown Castle and SBA Communications, which rent space on them to Verizon, AT&T, T-Mobile and others. One tower often carries two or three carriers at different heights. The FCC registration names the owner; it does not list the tenants.
How do you know which carriers are on a tower?
From phones. OpenCelliD collects reports of the cell signals phones see and where they saw them. When reported cells sit within 200 meters of a registered structure, we list those carriers on that structure. It is strong evidence, not a lease record, and it can miss a carrier nobody has reported yet.
Why isn't every cell site on the map?
The FCC only requires registration for structures taller than 200 feet or close to an airport. Rooftop antennas, small cells on street poles and many shorter towers never register. Where phones report a cell site with no registered structure nearby, we show it as an approximate crowdsourced site, which can be off by a few hundred meters.
