Channel Raster
NR Channel Raster
Step size grid used to define carrier center frequencies across RF spectrum bands.
Technical Explanation
The channel raster specifies the RF channel spacing increments for carrier center frequencies. In 3GPP NR, the raster step size Delta_F_Raster is 5 kHz for frequencies below 3 GHz, 15 kHz for 3 GHz to 24.25 GHz, and 60 kHz for millimeter wave frequencies from 24.25 GHz to 100 GHz.
Key Functions
- Defines valid RF center frequencies for carrier deployments
- 5 kHz step for sub-3 GHz, 15 kHz for mid-band, 60 kHz for mmWave
- Ensures standardized carrier placement without inter-operator overlap
