New mac structure l.jpg

New MAC Structure

  • A Regular Wifi Uses Contention access

    Which means competing for AP.

  • Wimax uses scheduling MAC

    Much Better for QOS required services EX: VOIP , IPTV

  • Mesh Networking

    Subscriber station and Base station at same time

  • OFDMA


New mac structure cont l.jpg

New MAC Structure (cont.)

  • Supports ATM

  • Packet based Control

  • MAC is flexible enough to efficiently carry any traffic type. Payload header suppression, packing, and fragmentation, the convergence sublayers and MAC.


Frequency l.jpg

Frequency

  • Originally Working 10 to 66ghz

    FDD or TDD.

  • Now supporting 2 to 11ghz with 802.11a. OFDMA with TDMA access.
