Summary

Below 6 GHz, T-Mobile holds the most licensed spectrum in Cook County with 438 MHz. AT&T leads in low-band, the layer that decides rural and indoor coverage, with 84.84 MHz. Verizon holds the most mmWave (1850 MHz), which only matters in the densest few blocks. SpaceX holds 75 MHz intended for satellite-to-phone service, not towers. The FCC has 213 records here from 35 licensees, 49 of them leases.

MHz, uplink and downlink combined, for the five national operators. An operator is credited with spectrum it is licensed for and spectrum it leases in; spectrum it leases out is not subtracted. FirstNet Band 14 is credited to AT&T. Each CBRS Priority Access Licence counts as 10 MHz of high-band. Counting rules.
