n3: Introducing 5G NR Frequency Band

n3 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

Downlink (MHz)

1805 to 1880 MHz

UL NR-ARFCN

342000 to 357000

DL NR-ARFCN

361000 to 376000

Duplex Spacing

95 MHz

Supported Channel Bandwidths

5 10 15 20 25 30 MHz

Summary:

In many countries, n3 (1800MHz), or commonly referred to as the 1.8 GHz 5G band, is a commonly tested and deployed 5G frequency. The n3 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.

n3 Coverage

n3 coverage is excellent in range and building penetration due to the propagation characteristics of these frequencies used, and improved by advanced processing techniques.
