Wi-MAX Technology

WiMAX(802.16) stands for World Interoperability for Microwave Access.

WiMAX is the replacement of the wired broadband.

Objective of WiMAX


  • Superior Performance

  • Flexibility

  • Advanced IP-Based Architecture

  • Attractive Economics

IEEE 802.16 Specifications

  • Range 30 mile radius from the base station for LOS (line-of-sight).

  • Range 4-6 miles radius from the base station for NLOS (Non-line-of-sight)

  • Maximum data speed supported as 70 Mbps.

  • Licensed frequency band: 2- 11 GHz

  • Un-licensed frequency band: 10- 66 GHz

  • Line of sight is not needed between user and the base station unless very high date rates are required at the user premises.

The WiMAX certification for the release 1.0 profile started with a Wave 1 subset, excluding MIMO and a few optimization features, to enable early market deployments. This was followed by Wave 2, which progressively adds more and more feature tests over time based on vendors and testing tool availability. The early phases of certification were also limited to MAC and PHY layer conformance and interoperability testing, which will be expanded to add networklevel testing.
