n40: Introducing 5G NR Frequency Band
n40 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
Operating Band (MHz)
2300 to 2400 MHz
460000 to 480000
Supported Channel Bandwidths
5 10 15 20 25 30 40 50 60 80 100 MHz
In many countries, n40 (2300 MHz), or commonly referred to as the 2.3 GHz 5G band, is a commonly tested and deployed frequency. The n40 band’s popularity is due to its relatively common availability, often 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 often have to implement 5G NR on higher cellular bands. Lower frequencies are preferred for long-range rural coverage, conversely, dense urban networks can benefit from frequency-resuse inherent in using higher frequency bands.
n40 coverage is excellent in range and building penetration due to the propagation characteristics of the frequencies used, enhanced further by advanced processing techniques.
