Thing is, many of these networks have been sort of outside the mainstream - run as separate wired networks, sometimes linked to a computer but often to a control panel that flashes lights or sounds an alarm when a temperature rises too high or a machine vibrates too much. One of the technologies designed to help make these networks more enterprise-palatable is IEEE 802.15.4 or ZigBee as it is known from the group driving its development, the ZigBee Alliance. ZigBee is intended as a specification for low-powered networks for such uses as wireless monitoring and control of lights, security alarms, motion sensors, thermostats and smoke detectors. 802.15.4/ZigBee networks are slated to run in the unlicensed frequencies, including the 2.4-GHz band in the U.S. 802.15.4 is part of the 802.15 wireless personal-area network effort at the IEEE. It is a simple (28K byte) packet-based radio protocol aimed at very low-cost, battery-operated widgets and sensors (whose batteries last years, not hours) that can intercommunicate and send low-bandwidth data to a centralized device. According to our Technology Update author ( <mailto:[EMAIL PROTECTED]> ) the v.1.0 draft of the ZigBee specification is set for release in the fourth quarter and a number of platforms based on the standard are expected to be available around the same time.
