Can we use WiMax technology as a backbone (say to replace fiber optics) with the same efficiency as fiber? We want to connect equipment between cities. Can we use WiMax and have sufficient bandwidth?

WiMax is a wireless technology that can provide up to 70M bit/sec of throughput over several miles in the unlicensed or licensed bands. While there are vendors with early pre-standard implementations available, the industry is looking towards the end of 2005 for the general availability of Wi-Max radios based on the first generation of WiMax silicon. So if your bandwidth requirements are on the order of 50M bit/sec. and the distance between the two points you are trying to connect are on the order of 10 miles, WiMax may be a good solution. In general, no wireless technology – including WiMax – will provide the same bandwidth or reliability available over a fiber cable. But then again, you do not need to dig a trench to get your WiMax link up and running.

The answer to that question depends on your bandwidth requirements. As is currently being defined in the IEEE, the WiMax Forum is focusing on the 802.16a protocol. That version allows for a max of 100M bits/sec per 20 MHz channel with a transmission range of a maximum of 30 miles. Although the performance of fiber may be more than what WiMax may provide, the ability to deploy and provision across urban areas and into rural areas is its biggest advantage.
