Wimax Worldwide Interoperability for Microwave Access A certification mark for products that pass conformity and interoperability tests for the IEEE standards Run by Wimax Forum

Content History Of Wireless Wimax Advantages Over Wifi MAC Structure Usage Areas CompetitorsConclusion

Advantages Over Wifi Improved Performance Much Greater Distances Much Better MAC LNOS Ability

Content History Of Wireless Wimax Advantages Over Wifi MAC Structure Usage Areas CompetitorsConclusion

New MAC Structure A Regular Wifi Uses Contention access Which means competing for AP. Which means competing for AP. Wimax uses scheduling MAC Much Better for QOS required services EX: VOIP, IPTV Much Better for QOS required services EX: VOIP, IPTV Mesh Networking Subscriber station and Base station at same time Subscriber station and Base station at same timeOFDMA

New MAC Structure (cont.) Supports ATM Packet based Control MAC is MAC is flexible enough to efficiently carry any traffic type. Payload header suppression, packing, and fragmentation, the convergence sublayers and MAC.
