Describe the WiMAX MAC layer.
What will be an ideal response?
The MAC layer of WiMAX is different than that used in IEEE 802.11a/b/g (CSMA/CA) or Ethernet (CSMA/CD). Instead, WiMAX uses a scheduling system and the device only has to compete once for initial entry into the network. Once the device has been accepted it is allocated a time slot. Although this time slot can expand and shrink, it remains assigned to that device and other devices must take their turn.
