Background Application of industrial automation (sensors, actuators), with high density of nodes communicating over RF. Industrial requirements typically: power consumption per node <100mW many hundred nodes in a network guaranteed response within 20-50 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) ZigBee i industrien:
Possible solution: ZigBee by Philips (IEEE 802.15.4) 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 802.11b and Bluetooth (theoretical and practical) Experimental ZigBee network (including miniature stack implementation) Theoretical and practical study of network layer Organisation: Niels D.
