Transcript

  • 1. WIMAX presented by Bhanu & Prashant
  • 2. INTRODUCTION
    • Think about how you access the Internet today.
    • There are basically three different options:
      • BROADBAND ACCESS
      • WIFI ACCESS
      • DIAL-UP ACCESS
    • The main problems with broadband access are that it is pretty expensive & it doesn’t reach all areas.
    • The main problem with WIFI is that hot spots are very small, so coverage is sparse.
  • 3. What if there were a new technology that solved all of these problems?
    • This new Technology would provide:-
    • High speed of broadband service
    • Wireless rather than wired access
    • That is less expensive than cable
    • Much easier to extend to rural areas
    • Broad coverage like cell phone networks.
    All this is possible with WIMAX
  • 4. WHAT IS WIMAX?
    • WIMAX stands for Worldwide Interoperability of Microwave Access.
    • WIMAX is a wireless digital communications system also known as IEEE 802.16.
    • WIMAX can provide broadband wireless access up to 30 miles(50 km) for fixed stations and 3-10 miles(5-15 km) for mobile stations.
    • It involves microwaves for the transfer of data wirelessly.
  • 5. How does WIMAX Work ?
    • A WIMAX 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.
    • This connection to a second tower, along with the ability of a single tower to cover up to 30 square miles, is what allows WIMAX to provide coverage to remote rural areas.
  • 6.
  • 7. Reliance WIMAX broadband delivery
  • 8. How WIMAX Works ? (continued)
    • In practical terms, WIMAX would operate similar to WIFI but at higher speeds, over greater distances and for greater number of users.
    • WIMAX could potentially erase the suburban & rural blackout areas that currently have no broadband internet access because phone and cable are not yet reached the remote locations.
  • 9. Wi-Fi hotspot. Soon, Mobile WIMAX will blanket large areas—metropolitan, suburban, or rural—delivering mobile broadband Internet access at speeds similar to existing broadband.
  • 10. ADVANTAGES
    • Single station can serve hundred of users.
    • Quick Installation:
      • Getting your connectivity up and working as quickly as possible. If you are moving, starting up at a new location or need a fast back-up solution, the WIMAX service is ideal.
    • High data rate
    • Large coverage
    • Line of sight not needed b/w user & base station.
    • Relief from cabling cost.
  • 11.
    • Security
    • Bandwidth Flexibility
    • Pricing + Contract Flexibility:
      • WIMAX service offers pricing based on your bandwidth demands.
  • 12. DISADVANTAGES
    • Line of sight is needed for more distant connections.
    • Susceptible to weather effects like rain etc.
    • Other wireless equipments could cause interference.
    • WIMAX is a very power consuming technology.
    • High cost of design, implementation and maintenance.
  • 13. WIMAX Applications & Services Applications :
    • Last Mile: Broadband Internet access.
    • Backhaul network
    • Hospital
    • Traffic management
    • Deploying infrastructure for events
    • Military and Defense
  • 14.
    • Services :
    • Network backhaul
    • VoIP
    • Interactive gaming
    • Web browsing
    • File transfer
    • Streaming multimedia (video conferencing)
  • 15. TYPES OF WIMAX
    • FIXED WIMAX:
      • Fixed WIMAX deployments do not cater for hand off between base stations, therefore the service provider cannot offer mobility.
    • MOBILE WIMAX:
      • Mobile WIMAX implementations can be used to deliver both fixed & mobile services.

  • 17. COMPARISON b/w WIMAX & WIFI
    • WIMAX
    • WIMAX is a long range system, covering many kms that typically uses licensed spectrum to deliver a point-to-point connection to the internet from an ISP to an end user.
    • WIMAX provides services analogous to cell phone.
    • WiFi
    • WiFi is shorter range system, typically hundreds of meters, that uses unlicensed spectrum to provide access to a n/w.
    • WiFi is more analogous to a cordless phone.
  • 18.
    • It uses a mechanism based on setting up connections between the base station & user device. Each connection is based on specific scheduling algos, which means that quality of service can be guaranteed.
    • WiFi has introduced a quality of service mechanism similar to fixed Ethernet, where packet can receive different priorities based on their tags. This means that QOS as opposed to guaranteed.
  • 19. BROADBAND ACCESS
    • Many companies are closely examining WIMAX for “last-mile" connectivity at high data rates.
    • The resulting competitions may bring lower pricing for both home & business customers, or bring broadband access to places where it has been economically unavailable.
  • 20. Networks around the world WiMAX Networks around the World Beginning in 2004
    • Europe: WIMAX networks have
    • made their presence in Europe since
    • as early as 2004.
    • Norby Telecom and Wi-Manx
    • were one of the first companies in
    • Europe to deploy commercial WiMAX
  • 21.
    • Italy was one of the last European
    • nations to join the WiMAX race.
    • China Netcom has provided
    • residential users of China with fixed
    • Broadband Wireless Access since 2006.
    • South Korean telecom industries
    • have supplied a huge contribution to
    • the development of
    • Mobile WiMAX (802.16e), which
    • they referred to as WiBro .
    • South America & North America
    • have also established WIMAX
    • networks there.
  • 22. FUTURE
    • Anywhere, Anytime Connectivity
      • WIMAX offers such kind of service, so that you can get a connection, wherever you are & at a higher speed.
      • When WIMAX will be fully developed, you will no longer be limited to 300 feet within the WIFI hotspot, & you won’t have to drive around looking for a connection….
  • 23.
    • Cost Effective
      • There are areas of the world-especially in rural areas-where deploying wired broadband infrastructure is not cost effective.
      • In this case WIMAX will be very cost effective.
      • Summing up WIMAX will replace other wireless
      • technologies.
