  9. 9. MAC LAYER  Device Classes  Full function device (FFD)  Can talk to any device.  Reduced function device (RFD)  Cannot talk to all the devices.  Address  All devices must have 64 bit IEEE addresses  Short (16 bit) addresses can be allocated to reduce packet size
  10. 10. DEVICES • Zigbee Coordinator (ZC): • it is the root of the network tree • acts as a bridge to other networks. • Zigbee Router (ZR): • acts as an intermediate router. • Zigbee End Devices (ZED): • functionality to talk to the parent node. • cannot relay data from other devices • allows the node to be asleep .
  11. 11. MAC LAYER  Transmission Mode  Beacon enable mode  Periodic data  Repetitive low latency data using.  Non-Beacon enable mode  Intermittent data using.
