WiMax isn't competing with Nextel's solution. To quote WiMax's own information page WiMax supports " fixed broadband wireless access systems"
For the moment, you maybe right. However, 802.16 has a mobile boradband working group which is developing the 802.16e - standard to support mobile broadband wireless access. After the approval of this standard by the IEEE, the Wimax will be responsible for certifying products and technologies for this mobile standard. This way, mobility will also be supported.
