  5. 5. Background <ul><li>Related Technologies </li></ul><ul><li>OFDM </li></ul>
  6. 6. Practical Applications <ul><li>Backhaul </li></ul><ul><ul><li>Tower to Tower </li></ul></ul><ul><li>Last-mile </li></ul><ul><ul><li>From Towers to ISP (WISP) </li></ul></ul><ul><li>Mesh </li></ul><ul><ul><li>Devices connecting to each other </li></ul></ul><ul><li>Emerging Markets </li></ul><ul><ul><li>China & India </li></ul></ul><ul><li>Under-serviced Rural Areas </li></ul><ul><ul><li>Pockets of homes with no “fast copper” </li></ul></ul>

  8. 8. “Triple-Play” <ul><li>This is really the Holy Grail of communication companies: </li></ul><ul><ul><li>Voice – All over “landline” quality </li></ul></ul><ul><ul><li>Data - >1Mbps anywhere </li></ul></ul><ul><ul><li>Video – IPTV anywhere Television </li></ul></ul>
  9. 9. Low Cost Non-LOS <ul><li>Currently have to have technician installed devices like “Dish” network </li></ul><ul><li>Goal is for customer installed devices that are not required to be in line with the tower </li></ul>
