  1. 1. This  slide  was  not  presented  White  Spaces:  The  Radio  Evolu5on  Tuesday  -­‐  09/13/11  •  3:30-­‐4:15pm  Brough  Turner  ,  Founder  ,  netBlazr.com      Smart  antennas  and  smart  radios,  Cogni7ve  Radio   and  Beam  Forming  are  on  the  verge  of  being   incorporated  into  product.  As  we  head  toward   these  technologies,  the  opportuni7es  exist  for   new  models  of  service  sharing  and   interconnec7on  to  deliver  broadband  solu7ons.

  5. 5. Outline…  •  Value  of  higher  frequencies   –  Limits  are  tech  not  physics;  MIMO;  beamforming;   HF  -­‐>  shorter  WL  -­‐>  7ghter  beams   –  >  3  GHz  is  mostly  white  space  in  most  places  •  SB  seeking  secondary  access  now  •  Example  of  app  at  5  GHz    
  6. 6. Spectrum  Myth  TV  bands  are  “beach  front”  spectrum  •  Based  on  legacy  technology,  not  physics!   –  Travels  farther  thru  the  air  –  No!   –  Thru  windows  –  roughly  the  same   –  Goes  thru  masonry  –  nothing  works  well   7  
  7. 7. Free  space  path  loss   Seems  to  say  more    ,  more  loss  But  this  equa7on  encapsulates  two  effects:     Actual  path  loss     Receiving  antenna  aperture  (assumed  to  be  ½  wavelength)  5  GHz  photons  go  just  as  far  as  700  MHz  photons  !   8
