• Typical range 1-100m.

• ISM (Industrial, Scientific & Medical) radio bands :- - 2.4 GHz Global Band at 250kbps (16 Channels) - 868 MHz European Band at 20kbps (1 Channel) - 915 MHz North American Band at 40kbps (10 Channels)

• Low power consumption ( Battery life from multi-months to years).

• Bi-directional.

• Support for low latency devices (few ms maximum)

• CSMA-CA channel access.

• Capable of connecting 65,536 devices per network

Zigbee Origin

• The IEEE 802.15.4 standard was completed in May 2003.

• The ZigBee specifications were ratified on 14 December 2004.• The ZigBee Alliance announced public availability of Specification 1.0 on 13 June

2005. • Much research is still going on with ZigBee.
