The new standard makes it possible to stream data from sensors married to passive tags, by allocating a frequency channel to each device. When radio waves reaches a tag, the device wakes up and broadcasts the basic info it contains and then negotiates a clear channel on which to stream data.

I've had ZigBee door/window sensors last as little as a few weeks on a AAA battery, making them practically unusable.
