One Wireless Standard to Rule Them all, ZigBee 3.0
The last time I checked Zigbee was up to ten standards, all based on different solutions or sector depending on the use of the product. Neighborhood Area Network (NAN) was the last one I heard about. with some standards and the possible that one manufactore might might manufacture for different makrets can mean a lot of work. The ZigBee Alliance has seen this and has unified all its wireless standards under one standard called ZigBee 3.0.
