RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Up until fairly recently ZigBee and WLAN together were believed by pundits to be a low data rate and high data rate, respectively, replacement for Bluetooth. Now, it appears ZigBee will be carving out a niche below and overlapping with Bluetooth integration opportunities. As a cheaper to manufacture and simpler to integrate platform, ZigBee is making rapid advancements. User groups are still hashing out details, and like with Bluetooth, ZigBee will certainly undergo a second round of specification tweaking once enough models are deployed in consumer products to gain significant feedback.
Pricing appears to be in the $1 target range, which does make ZigBee more attractive then Bluetooth where application do not require more than a few 10s of kbps data. One big advantage ZigBee has over Bluetooth is a sleep mode that keeps battery drain to a minimum and allows some applications to go for years between battery changes. The links listed here will get you started in your quest for ZigBee technology information.
According to the ZigBee Alliance, it derives its name from the zigzag path of bees that serves to signal a new food source to other members of the colony. The bee's survival depends on the continuous communication of information between every member of the colony.
