n1 – 5G NR Frequency Band – 2100MHz FDD

n1: Introducing 5G NR Frequency Band

CableFree 5G NR Radio Band n1

n1 is a frequency band designated by the 5G NR standard. Note that in 5G, the NR bands are defined with prefix of “n”. When the NR band is overlapping with the 4G LTE band, they share the same band number.

5G Band Name


Duplex Mode


Uplink (MHz)

1920 to 1980 MHz

Downlink (MHz)

2110 to 2170 MHz


384000 to 396000


422000 to 434000

Duplex Spacing

190 MHz

Supported Channel Bandwidths

5 10 15 20 MHz


In many countries, n1 (2100MHz), or commonly referred to as the 2.1 GHz 5G band, is a commonly tested and deployed 5G frequency. The n1 band’s popularity is due to its relatively common availability, already widely in use by 3G and 4G networks. Operators may “re-farm” existing 3G networks on these frequencies to re-purpose for 5G networks.

Key performance objectives of the 5G NR standard require large blocks of contiguous spectrum to operate large channel widths and hence offer users high capacity throughput. With spectrum a valuable resource, operators have to implement 5G NR on higher cellular bands.

n1 Coverage

n1 coverage is excellent in range and building penetration due to the propagation characteristics of these frequencies used, and improved by advanced processing techniques.
