WiMax, like WiFi, is an IP-based wireless technology. Both are designed to deliver high-speed internet wirelessly. That is the similarity, but now it’s time for the differences.

WiFi was originally meant to provide indoor wireless connectivity, typically over a very short distance. WiFi is suitable for home networks or in a smaller public space, like a coffee shop. There have been attempts to “mesh” the technology and use for a citywide application as a whole. However, to materialize that, there would be a need to deploy hundreds of radios for city coverage of just a few kilometers. This dramatically raises the project cost and makes it a financially less viable option. Another major differentiator between WiMax and WiFi lies in the usage of the radio spectrum. This might sound surprising, but WiFi uses an unlicensed spectrum. However, WiMax uses a licensed spectrum, typically in the 2.5MHz range.

Interestingly, WiMax is often referred to as ‘WiFi on steroids’. Networking academic experts like Scott Shamp opine that WiMax is an interesting mix of cellular and WiFi networks. WiMax gives you the high-speed internet like WiFi, along with much wider network coverage, like a typical cellular network. Also, since WiMax is designed to be a carrier-grade technology, there is much more reliability and quality of service built in, as compared to a typical WiFi system.

Advantages of wireless networking
Increased efficiency
Improved data communications lead to faster transfer of information within businesses and between partners and customers. For example, salespeople can remotely check stock levels and prices while on sales calls.

Access and availability
Because wireless technology allows the user to communicate while on the move, you are rarely out of touch – you don’t need extra cables or adaptors to access office networks.

Flexibility
Office-based wireless workers can network without sitting at dedicated computers and can continue to do productive work while away from the office. This can lead to new styles of working, such as home working or direct access to corporate data while on customer sites. See more on employees working from home.

Cost savings
Wireless networks can be easier and cheaper to install, especially in listed buildings or where the landlord will not permit the installation of cables.

New opportunities
Wireless networking could allow you to offer new products or services. For example, many airport departure lounges, train stations, hotels, cafes and restaurants have installed ‘hot spot’ WiFi services to allow mobile users to connect their equipment to their ‘home’ offices while travelling.
