What is different about 802.16a is not just that it uses W-OFDM. As you asked, what is different about that than the use of OFDM found in 802.11a/.11g? Well, there are some major differences including how finely grained the channelization is designed. But more significant is the ability of 802.16a to combine various technologies to enhance NLOS and range characteristics. Wi-Lan has a 'basic' patent on W-OFDM, a base technology used in 802.16a WiMAX systems. But one of the strengths of W-OFDM is the ability to use smart targetable array antenna systems, MIMO and other enhancements much more effectively than can be done using 802.11 standards.
