Hi, everyone... Welcome.. Today i am going to discuss about WI-MAX. wireless interoperability for microwave access is the latest evolution in the area of telecommunication systems. The major difference between wi-fi and wi-max is, that wi-max can provide internet access upto 248 kms (i.e) for an entire city. It uses IEEE 802.16 technology of wireless communication. In the near future, wi-max will be replacing other wired and wireless networks on a large scale.
