ZigBee i industrien:

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
