See how much spectrum Verizon, AT&T, Sprint and T-Mobile have for LTE and where it is located

Spectrum is the lifeblood of the wireless industry, and the amount of spectrum that individual operators control determines their network capacity in specific markets and even their network speeds. With this in mind, FierceWireless has partnered with wireless consulting firm AllNet Labs to map out exactly how much spectrum each of the four U.S. Tier 1 carriers currently has that could be deployed for LTE service. The measurements are broken down on a county-by-county basis. AllNet's Spectrum Analysis Tool evaluations are based on a June 2014 FCC dataset, and leased spectrum is included.
