Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-7 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...
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.

As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10 n) metres, with corresponding frequency of 3×10 8−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name.
However, none of them have achieved universal acceptance. Competitors include Xiaomi and Nokia. 6G is expected to offer faster speeds than 5G but with a shorter range. The IEEE recommends the use of frequencies ranging from 100 GHz to 3 THz, as these frequencies are relatively unused and would allow for exploration of new frequency bands. [8]
5G Broadcast (5GB), officially known as LTE-based 5G Terrestrial Broadcast, is a system for the distribution of television and other broadcast media content via terrestrial radio broadcast networks based on downlink-only LTE technology. [1] [2] 5G Broadcast focuses mainly on mobile use cases like smartphones and in-car radio.
