ZigBee
From Computing and Software Wiki
ZigBee, is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate, 20-250Kbps depending on the band. The protocol is designed with security in mind, such as using AES-128 encryption.
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies that which also controls the specification.

Uses
ZigBee is based on radio frequency (RF) technology and mesh networking. It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.
The current application is for low power, low data rate wireless sensor networks (WSN).
Technical Information
It is a suite of protocols that covers from the Physical layer, Network layer to the Application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).
Standards
Market
With the WSN market grow to estimated $4.6 billion in 2011, up from $500 million in 2007; ZigBee is a strong contender to become the standard for WSN. Companies can adopt this protocol into its products in an attempt to gain the market share. Also, industrials plants can gain the benefits from better monitoring and control of process, thanks to the lost cost and easy of deployment of wireless sensor networks based on ZigBee.
