Industrial requirements typically: power consumption per node <100mW many hundred nodes in a network guaranteed response within ms. Bluetooth has been used for industrial applications. Suffers from: short range small picocells, (relatively) high consumption high bitrate no real-time guarantee ABB has developed proprietary solution (not industry standard)

Aakvaag 5 ABB ZigBee i industrien: Possible solution: ZigBee by Philips (IEEE ) Low bandwidth Low power consumption High number of active nodes Will probably gain industry-wide acceptance Elements: Comparison of Bluetooth and ZigBee based on available specification Study of interference problems with b and Bluetooth (theoretical and practical) Experimental ZigBee network (including miniature stack implementation) Theoretical and practical study of network layer Organisation:Niels D.
