current internet access technologies
Current Internet access technologies
  • Broadband
    • DSL
    • Cable
  • WiFi hotspots
  • Dial-up
wimax highlights
WiMAX Highlights
  • Speed
    • Faster than broadband service
  • Wireless
    • Not having to lay cables reduces cost
    • Easier to extend to suburban and rural areas
  • Broad coverage
    • Much wider coverage than WiFi hotspots

WiMAX Highlights
  • WiMAX
    • Worldwide Interoperability for Microwave Access
    • Is a certification mark for products that pass conformity and interoperability tests for the IEEE 802.16

WiMAX System Parts
  • WiMAX tower
    • Similar in concept to a cell-phone tower
      • Can provide coverage to a very large area -- as big as 3,000 square miles
  • A WiMAX receiver
    • The receiver and antenna could be a small box or PCMCIA card, or they could be built into a laptop the way WiFi access is today

WiMAX System Parts
  • A tower station can connect directly to the Internet using a high-bandwidth, wired connection
  • It can also connect to another WiMAX tower using a line-of-sight, microwave link.
    • Often referred to as a backhaul
    • Allows WiMAX to provide coverage to remote rural areas.
two forms of wireless service
Two forms of wireless service
  • Non-line-of-sight
    • A small antenna on your computer connects to the tower
    • 2 GHz to 11 GHz frequency range
    • Limited to a 4-to-6 mile radius
two forms of wireless service1
Two forms of wireless service
  • Line-of-sight service
    • A fixed dish antenna points straight at the WiMAX tower from a rooftop or pole.
    • 66 GHz frequency range
    • Higher frequencies, there is less interference and lots more bandwidth
    • 30-mile radius
  • Range
    • 30-mile radius from base station
  • Speed
    • 70 megabits per second
  • Line-of-sight not needed between user and base station
In practical terms, WiMAX would operate similar to WiFi but at higher speeds, over greater distances and for a greater number of users.

  • Cities might pay to have WiMAX base stations set up in key areas for business and commerce and then allow people to use them for free.
    • Similar to free WiFi hotspots, but wider range
  • Some companies might set up WiMAX transmitters and then make people pay for access.
    • Similar to paid WiFi hotspots, but wider range

  • Current high speed access method
    • The cable (or phone) company has a line that runs into your home.
    • That line goes to a cable modem, and another line runs from the modem to your computer.
    • If you have a home network, first it goes to a router and then on to the other computers on the network.

  • WiMAX access method
    • An Internet service provider sets up a WiMAX base station.
    • You would buy a WiMAX-enabled computer or upgrade your old computer to add WiMAX capability.
    • You would receive a special encryption code that would give you access to the base station.
    • The base station would beam data from the Internet to your computer
    • If you have a home network, the WiMAX base station would send data to a WiMAX-enabled router, which would then send the data to the different computers on your network.
  • The WiMAX protocol is designed to accommodate several different methods of data transmission, one of which is Voice Over Internet Protocol (VoIP).
  • SANTA CLARA, Calif., April 18, 2005 - Intel Corporation today announced the availability of its first WiMAX product, providing equipment manufacturers and carriers the ability to deliver next-generation wireless broadband networks around the world.
  • Several service providers worldwide announced plans to begin commercial WiMAX trials based on Intel silicon products later this year,
