WiMAX Question:

We need WiMAX technology for high speed broadband like internet access on the move. We have broadband connections that provide high speed networks, but are attached to LAN systems i.e. not portable. Wi-fi provides access to such systems but limited to a much shorter distance.
Then we have cellular networks which provide internet access but their speed is limited and they are relatively costly. To overcome these problems we need WiMax or comparable technology.
