4. Background What is WiMAX? What is WiMAX? –Worldwide Interoperability for Microwave Access – Brand name for 802.16 standards What is Wireless Broadband? What is Wireless Broadband? –Like DSL or Cable, only Wireless What is 4G? What is 4G? –High-speed data, voice and video to mobile devices – we use 3G devices now Why is this different than Wi-Fi? Why is this different than Wi-Fi? –Faster –Fewer “contentions” –More secure

5. Background Related Technologies Related Technologies OFDM OFDM

6. Practical Applications Backhaul Backhaul –Tower to Tower Last-mile Last-mile –From Towers to ISP (WISP) Mesh Mesh –Devices connecting to each other Emerging Markets Emerging Markets –China & India Under-serviced Rural Areas Under-serviced Rural Areas –Pockets of homes with no “fast copper”

7. Future “Triple-Play” for all mobile devices “Triple-Play” for all mobile devices Low-cost non-LOS Low-cost non-LOS Mesh Networks Mesh Networks

8. “Triple-Play” This is really the Holy Grail of communication companies: This is really the Holy Grail of communication companies: –Voice – All over “landline” quality –Data - >1Mbps anywhere –Video – IPTV anywhere Television

9. Low Cost Non-LOS Currently have to have technician installed devices like “Dish” network Currently have to have technician installed devices like “Dish” network Goal is for customer installed devices that are not required to be in line with the tower Goal is for customer installed devices that are not required to be in line with the tower

10. Mesh Networks The way it is now LAN 802.11g Wi-Fi Out of Range

11. Mesh Networks The Future This is WiMAX
