5G Bands in the USA

Federal Communications Commission (FCC) in the USA does not require to deploy any particular technology at a given band, i.e. any band that is in use to provide mobile service can be utilized for any technology including 5G. So previous auctions are also applicable to 5G, for example in March 1996 (2.5 GHz), March 1998 and May 1999 (28 GHz) and May 2000 (39 GHz) and so on. Further details on auctions can be found here.

A table below contains data about bands that to be used for 5G during initial launches.

Frequency Band	3GPP Band Number	Frequency Range	Duplex Mode	Operator	Comments
600 MHz	n71	DL: 617-652 MHz UL: 663-698 MHz	FDD	T-Mobile	Bandwidth varies from state to state
28 GHz	?	?	TDD	T-Mobile	Totally there are 200 MHz at 28 GHz and 39 GHz bands
39 GHz	n260	?	TDD	T-Mobile	Totally there are 200 MHz at 28 GHz and 39 GHz bands
28 GHz	?	?	TDD	Verizon	Totally there are 800 MHz at 28 GHz? It's 76% of the available 28 GHz band
39 GHz	n260	?	TDD	Verizon	Verizon owns 46% of the available 39 GHz band
39 GHz	n260	?	TDD	AT&T
2.5 GHz	?	?	TDD	Sprint

AT&T also owns some frequency blocks at 700 MHz and AWS-1 bands that can be refarmed for 5G later. See AT&T and others LTE bands in the USA.

In March 2019 there is an ongoing auction of spectrum in the 28 GHz (27.5 - 28.35 GHz) and 24 GHz (24.25 - 24.45 GHz and 24.75 - 25.25 GHz).
