The new IEEE 802.15.4 standard (part of ZigBee) for low-rate wireless personal area 
networks (LR-WPAN) is a global standard addressing the needs of low-rate applications 
requiring devices of very low complexity, cost and possessing multi-month to multi-year 
battery life. ZigBee is aimed at building and industrial automation/control and several 
other applications involving wireless sensor networks. This talk will discuss the features 
and potential of this evolving standard.
