17. 1 1 Introduction to ZigBee ZigBee is a specification for a suite of high level communication protocols using small low power digital radios based on the IEEE 802 15 4 standard for personal area networks ZigBee devices are often used in mesh network form to transmit data over longer distances passing data through intermediate devices to reach more distant ones This allows ZigBee networks to be formed ad hoc with no centralized control or high power transmitter receiver required in order to reach all of the devices Any ZigBee device can be tasked with running the network ZigBee is targeted at applications that require a low data rate long battery life and secure networking ZigBee has a def ined rate of 250 kbit s best suited for periodic or intermittent transmission of data or for a single signal transmission from a sensor or input device Applications include wireless light switches electrical meters with in home displays traffic management systems and other consumer and industrial equipment that requires short range wireless transfer of data at relatively low rates The technology defined by the ZigBee specification is intended to be simpler and less expensive than other WPANs ICP DAS ZT 2026 User Manual Version 1 0 1 Page 7 Copyright 2013 by ICP DAS Co Ltd ALL Rights Reserved 1 2 Introduction to the ZT 2000 I O Series The ZT 2000 1 0 series of devices are small wireless ZigBee 0 modules based on the IEEE802 15 4
