n257 is a 5G FR2 mmWave band. It operates from 26.5 to 29.5 GHz, a frequency previously used for millimeter-wave point-to-point services. The band was designed to harmonise with the spectrum plans of Japan, North America, and South Korea, but is available for use globally. This band is capable of significantly expanding the capacity and speed of 5G networks due to its large bandwidth.
