WiMAX, an approximate acronym of Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides for the wireless transmission of data using a variety of transmission modes, from point-to-pointIEEE 802.16 standard (also called WirelessMAN). The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL"[1] (and also to High Speed Packet Access).[citation needed] links to full mobile cellular-type access. The technology provides up to 70 Mb/sec symmetric broadband speed without the need for cables. The technology is based on the

Currently, Pakistan has the largest fully functional WiMAX network in the world.[2] Wateen Telecom installed the network (with an initial rollout in seventeen cities) throughout Pakistan using Motorola hardware. Wateen is also planning to expand its network and eventually cover 71 cities in Pakistan.


The terms "fixed WiMAX", "mobile WiMAX", "802.16d" and "802.16e" are frequently used incorrectly.[4] Correct definitions are the following:
  • 802.16-2004 is often called 802.16d, since that was the working party that developed the standard. It is also frequently referred to as "fixed WiMAX" since it has no support for mobility.
  • 802.16e-2005 is an amendment to 802.16-2004 and is often referred to in shortened form as 802.16e. It introduced support for mobility, amongst other things and is therefore also known as "mobile WiMAX"


The bandwidth and range of WiMAX make it suitable for the following potential applications:

  • Connecting Wi-Fi hotspots to the Internet.
  • Providing a 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. That is, if a business has a fixed and a wireless Internet connection, especially from unrelated providers, they are unlikely to be affected by the same service outage.
  • Providing portable connectivity.
