⌘ 802.11 ad standard

  • addresses 60 GHz communications, 5.7 GHz available bandwidth
  • Wavelength mm
  • antenna on chip
Application areas:
  • set-top boxes, TV, high-bandwidth cable replacement
  • direct backbone links
  • industrial construction area
  • communications in public places
Conclusions from NY University, [1]
  • Measurements at 38 and 60 GHz show that NLOS links can be made with steerable antennas, with 20 – 30 dB loss compared to free space line-of-sight.
  • A link was always made using steerable antennas within a 200 m cell radius.
  • 38 GHz showed more NLOS links than 60 GHz
  • Cellular AOA distributions show BS should be deployed site-specifically (due to shadowing of buildings)
  • Worst RMS delay spread link was 122ns, similar for peer- to-peer and cellular
