Introduction
   Teresa Furnish
    – Post-bac student, here to add Business Admin
      with Accounting and MIS to my English and
      Liberal Studies degree; planning to work in the
      field of IT audit & compliance
   Rod Gwinn
    – 20 years in IT; Last position was IT Director for
      large law firm; Will move into IT consulting after
      school
   Charlie Thompson
    – IT intern
Background
   What is WiMAX?
    – Worldwide Interoperability for Microwave
      Access – Brand name for 802.16 standards
   What is Wireless Broadband?
    – Like DSL or Cable, only Wireless
   What is 4G?
    – High-speed data, voice and video to mobile
      devices – we use 3G devices now
   Why is this different than Wi-Fi?
    – Faster
    – Fewer “contentions”
    – More secure
Background

   Related
    Technologies

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

   “Triple-Play” for all mobile devices
   Low-cost non-LOS
   Mesh Networks
“Triple-Play”

   This is really the Holy Grail of
    communication companies:
    – Voice – All over “landline” quality
    – Data - >1Mbps anywhere
    – Video – IPTV anywhere Television
Low Cost Non-LOS

   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
Mesh Networks
                The way it is now



                     LAN 802.11g Wi-Fi


Out of Range
Mesh Networks
                The Future


                 This is WiMAX
Wrap Up

   WiMAX Forum
   Nonprofit body
    – Standards
    – Testing
    – Certification
Glossary of Terms
   3G: Third generation of cellular networks, may complement
    or compete with WiMAX.
   Backhaul: Connection of one WiMAX tower to another
    WiMAX using a line-of-sight, microwave link.
   BWA: Broadband Wireless Access.
   HIPERMAN: European standard, similar to IEEE 802.16.
   IEEE 802.16: A formal standard used in implementation of
    WirelessMAN. The current version is IEEE Std 802.16e-
    2005[2].
   Mesh: A method of creating a wide range network by routing
    traffic in short hops between many access points.
   NLOS: Non Line of Sight.
   OFDM: Orthogonal Frequency-Division Multiplexing. WiMax
    uses scaleable orthogonal frequency-division multiplexing
    (SOFDM).
Glossary of Terms
   WAP: Wireless Access Point.
   WiBRO: South Korean standard, similar to IEEE 802.16 and
    will be harmonized with IEEE 802.16.
   WiMAX: Worldwide Interoperability for Microwave Access.
    Brand name for interoperable implementations of IEEE 802.16
    wireless networks. WiMAX certified equipment has
    interoperability with other certified equipment offered by
    different vendors. WiMAX offers full mobility support and
    delivers last mile broadband wireless access to rural regions.
    The WiMAX Forum manages certification, testing, branding
    and promotion.
   WirelessMAN: Wireless Metropolitan Area Networks
