The other is Frequency Range 2 (FR2), [2] which includes frequency bands from 24.25 GHz to 71.0 GHz. In November and December 2023, a third band, Frequency Range 3 (FR3), [ 3 ] covering frequencies from 7.125 GHz to 24.25 GHz, was proposed by the World Radio Conference ; as of September 2024, this band has not been added to the official standard.
In addition to radio frequencies used to connect handsets with cellular base stations, other parts of the radio spectrum are used to interconnect base stations and the wired telephone network. Some frequency bands may be vulnerable to interference by existing services in adjacent frequency bands, such as UHF television broadcasting.

It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth generation) long-term evolution standard. The 3GPP specification 38 series [3] provides the technical details behind 5G NR, the successor of LTE. The study of 5G NR within 3GPP started in 2015, and the first specification was made available by the end of 2017.

5G can be implemented in low-band, mid-band or high-band millimeter-wave. Low-band 5G uses a similar frequency range to 4G smartphones, 600–900 MHz, which can potentially offer higher download speeds than 4G: 5–250 megabits per second (Mbit/s). [3] [4] Low-band cell towers have a range and coverage area similar to 4G towers.
