5G NR N258 (mmWave 26 GHz)
The 5G NR frequency band n258, also known as the 26 GHz mmWave band, operates in the frequency range of 24.25 GHz to 27.5 GHz. This band is defined for Millimeter-Wave (mmWave) communication in 5G-NR networks and uses Time Division Duplexing (TDD) mode, which means it uses a single frequency band for both uplink and downlink transmissions.
Key characteristics of the n258 band include:
- Frequency Range: 24.25 GHz to 27.5 GHz
- Bandwidth: 3.25 GHz
- Channel Bandwidths: 50, 100, 200, and 400 MHz
- ARFCN Range: 2016667 to 2070833
- Geographical Usage: Primarily used in Europe and China
This band is part of the 24 to 29 GHz range, which is one of the most tested mmWave frequency ranges due to the availability of underutilized spectrum. It is designed for short-range high-data-rate transmissions and is less capable of traveling long distances compared to lower frequency bands, requiring closer base station placement and better penetration through solid objects.
