T-Mobile’s purchase of Sprint allowed T-Mobile to acquire a hoard of mid-band 2.5GHz spectrum and that gave the nation’s second-largest carrier a head start over Verizon and AT&T in building out a 5G network. Low-band spectrum covers more ground than other spectrum, penetrates structures better, but offers slower download data speeds closer to 4G LTE. High-band spectrum travels only short distances, has trouble penetrating structures, but delivers the fastest 5G speeds.
