Definition: 5G frequency bands

Within North America, 5G cellular service is able to operate in several frequency bands. The higher the frequency, the faster the speed; however, the signals are less capable of penetrating buildings, and the cell footprints are much smaller. More cell towers are required when transmitting in the high-band.

As of 2020, service is available in selected cities from each carrier. Verizon offers in-home service in the millimeter wave 28 and 39 GHz bands, and AT&T uses low-band and high-band frequencies. T-Mobile touts its low-band 5G as the first nationwide coverage. See 5G, 5G radiation and millimeter wave.
