ZigBee now comes in a box

摘要

Atmel has introduced a controller, radio, and protocol-stack implementation of ZigBee, a low-data-rate, low-power networked-wireless standard for control and monitoring applications. Atmel based ZigBee on the IEEE 802.15.4 standard, which stipulates a 20-, 40-, or 250-kbps data rate and that devices using it should run for at least two years without a battery change. Target applications include environmental control, security, industrial sensors, and medical monitoring systems that typically transfer small amounts of data with a low duty cycle. Other applications include home and office lighting, although ZigBee currently finds use only in high-end systems because of price.
