R&D/Technology: ZigBee: A long way to go?

The introduction of IEEE 802.15.4 low rate wireless personal area network (LR-WPAN) standard [1] was implemented for three reasons: the need for low-cost, low-power and short-range communication. While the 802.15.4 standard goes into great detail when describing the functionality of the physical (PHY) and medium access control (MAC) layer, security related issues received much less attention.
