what is zigbee technology
ZigBee is a wireless networking standard that is aimed at remote control and sensor applications which is suitable for operation in harsh radio environments and in isolated locations.ZigBee technology builds on IEEE standard 802.15.4 which defines the physical and MAC layers.Above this, ZigBee defines the application and security layer specifications enabling interoperability between products from different manufacturers. In this way ZigBee is a superset of the 802.15.4 specification.With the applications for remote wireless sensing and control growing rapidly it is estimated that the market size could reach hundreds of millions of dollars as early as 2007.igBee technology builds on IEEE standard 802.15.4 which defines the physical and MAC layers. Above this, ZigBee defines the application and security layer specifications enabling interoperability between products from different manufacturers.
ZigBee is a IEEE 802.15.4 -based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios.igBee-style self-organizing ad-hoc digital radio networks were conceived in the 1990s. The IEEE 802.15.4-2003 ZigBee specification was ratified on December 14, 2004. The ZigBee Alliance announced availability of Specification 1.0 on June 13, 2005, known as the ZigBee 2004 Specification.
