  • INTRODUCTION
    WiMAX (Worldwide Interoperability for Microwave Access)
    A standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DS
    IEEE 802.16 standard
    To provide fixed, nomadic, portable and, eventually, mobile wireless broadband connectivity without the need for direct line-of-sight (LOS) with a base station.
    For fixed and portable access applications Up to 40 Mbps per channel, in a cell radius of 3 ~ 10 km
    For mobile network deployments up to 15 Mbps per channel, in a cell radius up to 3 km
  • WiMAX Network: How It Works?
  • How WiMAX Works
    2 forms of wireless service
    Non-LOS, Wireless LAN sort of service, where a small antenna on a computer connects to the tower. Uses lower frequency range (2 to 11 GHz).
    LOS, where a fixed antenna points straight at the WiMAXtower from a rooftop or pole. The LOS connection is stronger and more stable, so it is able to send a lot of data with fewer errors. Uses higher frequencies upto66 GHz. Through stronger LOS antennas, WiMAX transmitting stations would send data to WiMAX enabled computers or routers set up within 30 (3,600 square miles of coverage) mile radius.
    Two types of connection
    Frequency Division Duplexing
    Time Division Duplexing
  • Types of Wi-Fi
  • Wireless LAN and WiMAX
    WiMAXeliminates the constraints of Wireless LAN.
    Unlike Wireless LAN, WiMAX is intended to work outdoors over long distances.
    WiMAXis a more complex technology and has to handle issues of importance such as QoSguarantees, carrier-class reliability, NLOS.
    WiMAXis not intended to replace Wireless LAN. Instead, the two technologies complement each other.

  • Comparison
    WiMax
    3G
    Lead to increased broadband penetration. Wimax scores for data
    Download speed upto 70 Mbps
    Initial cost is low
    Does not require significant investment in software and services, because it is inherently open
    Easy to compete for the service providers as low initial investment
    3G scores for voice
    Download speed upto 15Mbps
    Initial cost and maintenance cost is very high
    Require special software and services
    No of service providers are limited
  • WiMAX Applications
    According to WiMAX Forum it supports 5 classes of applications:
    1. Multi-player Interactive Gaming.
    2. Video Conference
    3. Streaming Media
    4. Web Browsing and Instant Messaging
    5. Media Content Downloads
  • WiMAX Advantages in a Nutshell
    Robust, reliable carrier class “last-mile” technology with QoS
    For many types of high-bandwidth applications at the same time, across long distances
  • WiMax service providers in India
    Tata Communications Internet Services
    Intel
    Bharat Sanchar Nigam Ltd
    BhartiAirtel and
    Reliance Communications
