What 5G bands are used in the USA?

The majority of commercial 5G networks are relying on spectrum in the 3.5 GHz range (3.3 GHz-4.2 GHz) .

The FCC concluded its first 5G spectrum auctions in the 28 GHz band; the 24 GHz band; and the upper 37 GHz, 39 GHz, and 47 GHz bands . With these auctions, the FCC is releasing almost 5 gigahertz of 5G spectrum into the market—more than all other flexible use bands combined.

Arguably the most useful band for 5G is mid-band , the range between 1 GHz and 6 GHz. Compared with low-band, there is more mid-band spectrum so it can deliver much faster throughput speeds and has far greater capacity.
