WiMax can also be seen as a wireless extension of fixed broadband. In USA, AT&T is looking at WiMax to provide broadband access to remote areas, and in countries like India the operators are doing the same. In Developing countries there is a significant number of wiMax Deployments and it is also staring in East Europe, France, etc.). What I find interesting in WiMax is the possibility that this technology may force Mobile operators to move from the cashcow model to a flat rate model, unlimited access that exists in most countries for fixed broadband. In the end, WiMax may lead to a radical change in Mobile market. Sprint has already indicated that they are planning to do something in these lines. A interesting market to watch is Korea where a Wimax (Wibro) like network is changing the rules of the game.
