Propagation Characteristics
Very short range (~100–200 m). Blocked by walls, foliage, even heavy rain. Requires beamforming with phased arrays. High path loss demands dense small-cell deployment.
Regulatory Notes
FCC licensed in US (n257, n261). 800 MHz channels available. Requires licensed spectrum. Separate from 24 GHz n258 (EU primary mmWave).
