New radio frequencies
See also: 5G NR frequency bands
The air interface defined by 3GPP for 5G is known as New Radio (NR), and the specification is subdivided into two frequency bands, FR1 (below 6 GHz) and FR2 (mmWave),[68] each with different capabilities.[69]
Frequency range 1 (< 6 GHz)
The maximum channel bandwidth defined for FR1 is 100 MHz, due to the scarcity of continuous spectrum in this crowded frequency range. The band most widely being used for 5G in this range is 3.3–4.2 GHz. The Korean carriers are using n78 band at 3.5 GHz although some millimeter wave spectrum has also been allocated.
Frequency range 2 (> 24 GHz)
The minimum channel bandwidth defined for FR2 is 50 MHz and the maximum is 400 MHz, with two-channel aggregation supported in 3GPP Release 15. In the U.S., Verizon is using n258 band 26 GHz and AT&T is using 39 GHz.[70] The higher the frequency, the greater the ability to support high data-transfer speeds.
