This just in from one of the newsletters I subscribe to,
===========
So is the low-power, low-data-rate specification known as ZigBee (IEEE
802.15.4). Pioneered by Philips, this standard is designed to
provide ultra-low-cost solutions for applications requiring both
low data rates and long battery life. The cost per module is
supposed to drop to $2 by next year.
Devices based on ZigBee will run at speeds ranging from 10 to
115.2 kbps, with a range of 10 to 75 m. Such devices are capable
of providing up to 254 nodes, including one master, managed from
a single remote control. ZigBee chips are expected to hit the
market within the next few months.
================
Should make the job a lot cheaper.
