WiMAX is a digital wireless data communication system that can deliver high-speed broadband services up to a large distance of 50KMs.The name WiMAX was created by WiMAX forum, the consortium promoting this standard. The term WiMAX is derived from the phrase Worldwide Interoperability for Microwave Access.
The WiMAX system was designed to popularize broadband access the way cell phones have done to our telephone communication system. WiMAX may replace the old form of broadband access through landlines, DSL and cable in future.
The WiMAX system can be considered as an efficient alternative to Wi-Fi, where the un-avoidable limitation was the distance of coverage. WiMAX solves this problem by using higher frequency range to deliver more data to a larger distance.

How WiMAX Works?

The following figure illustrates how the WiMAX works:

As shown in Figure, an Internet Service Provider gets connected to the internet from the internet backbone. Now, the service provider should choose the appropriate geographical locations according to his areas of coverage to set his base stations (WiMAX Transmitter) . Generally a base station would cover 30 miles of area and if the ISP wants more coverage area, he can install another base station which adds another 30 miles and this bridge continues depending on the ISP’s coverage requirements and connects them with the ISP Network.

Advantages of WiMAX

  • Large Area of Coverage: As WiMAX can deliver high-speed internet to large distance, it is very well suited to provide broadband access to remote areas of the world.
  • Scalability: As earlier mentioned, by using backhaul feature of WiMAX, you can set up large number of WiMAX towers in matter of days as opposed to wiring that requires proper planning and heavy labor.
  • In Built QoS: Quality of Service mechanisms in WiMAX allows mission-critical services to run smoothly even if there is lack of resources. This way, mission critical services are allowed to run at full priority when everything is busy.
  • Multi-User Connectivity: A single WiMAX tower can connect to 100 client receivers. These clients can of different modes of operation.

Disadvantages of WiMAX

  • Specialized Equipment Required: For utilizing full functionality of WiMAX, you need specialized hardware with dedicated antennae.
  • Limited Date Rate: When compared to other modes of broadband connectivity, for example, fibre optic cables and satellite internet, WiMAX is still slow.
  • Bandwidth Shared Among Users: WiMAX’s another drawback is that it distributes the bandwidth among users. This means, you will experience slow down when there are more uses in the base.
  • Speed Decrease over Large Distance: Because of bit rate errors happening at large distance, WiMAX system is forced to use lower bit rates at these distances. This means less data transfer rate.
  • Interference May Affect Connectivity: As the WiMAX uses radio waves, it is susceptible to interference caused by other equipments.
  • Rain can affect Connectivity: As fixed WiMAX requires line-of-sight radio link, heavy rain can disrupt the entire link.
