In practical terms it is a telecommunications technology that provides for wireless transmission of data using a variety of transmission modes, from point-to-point links to full mobile cellular type access.


On WiMax connectivity, one can achieve 70 Mb/sec symmetric broadband speed without the need for cables.


Presently Pakistan has the largest fully functional WiMax network in the world.



In technical terms, WiMax technology is called 802.16e-2005.



The bandwidth and range of WiMax provide following benefits.

  • Connecting Wi-Fi hotspots to internet.

  • Providing Wireless alternative to cable and DSL for last mile broadband access.

  • Providing data and telecommunications services.

  • Providing a source of Internet connectivity as part of a business continuity plan.

  • Providing portable connectivity.




  • WiMax technology had shown its technology prowess and edge during the Tsunami of Indonesia in December 2004 where the communications were maintained through this technology in inaccessible areas. Similarly, it was also used during the calamity caused by Katrina.


    This technology can exchange data over the distance of 50 KM. Secondly, it can utilize the bandwidth more efficiently accommodating more users. Thirdly, the devices required to access it not costly and provided by many manufacturers. Fourthly, it can be used in combinations of other telecommunication technologies like 3G, 4G, GSM, CDMA and cable network. Further, the cost can be further reduced if the mobile phones, Digital Television, PCs and laptops which will be receiving points, already come fitted with required chips.
