5G mmWave Band n257 (28 GHz)

5G ultra-high-speed hotspots · Dense urban deployments · Fixed Wireless Access

Frequency Range26.5–29.5 GHz
Wavelength10.2–11.3 mm
ITU / Standard—

Applications

  • →5G ultra-high-speed hotspots
  • →Dense urban deployments
  • →Fixed Wireless Access
  • →Venue/stadium coverage
  • →Industrial automation

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).
