ZigBee is HOT!

In today's wireless world, there are a zillion different standards and protocols. One of the key challenges is finding a standard that can apply to a product that is to be used in different markets -- in most cases, the product designed for the North American market must be completely redesigned on a different frequency before it can be marketed in Europe, and again for the Asian Pacific market. ZigBee™ is a open global standard for reliable, cost-effective, low power wireless applications based on the IEEE 802.15.4 standard, and looks to be the best way available now to help fix this situation. The first ZigBee™ devices are expected in early 2005.

The name ZigBee™ comes from the domestic honeybee, which uses a zig-zag type of dance to communicate important information to other hive members. This communications dance (the "ZigBee Principle") is what engineers are trying to emulate with this protocol -- a bunch of separate, simple organisms that join to together to tackle complex tasks. Besides, it's a catchy name, at least the equal to its rival Bluetooth!

We at Pegasus Technologies are in the process of designing a 2.4 GHz ZigBee™ module, and as a result have done a lot of research on this topic. Some of the stuff we have found is here. Happy hunting!

ZigBee™ is a trademark of the ZigBee Alliance
