This article is about a wireless protocol. For the fictional character, see Zigby. Zigbee wireless networking by drew gislason pdf or more general wireless networking such as Wi-Fi.
100 meters line-of-sight, depending on power output and environmental characteristics. Zigbee was conceived in 1998, standardized in 2003, and revised in 2006. The name refers to the waggle dance of honey bees after their return to the beehive. Zigbee is a low-cost, low-power, wireless mesh network standard targeted at battery-powered devices in wireless control and monitoring applications. Zigbee chips are typically integrated with radios and with microcontrollers.
Zigbee builds on the physical layer and media access control defined in IEEE standard 802. The Zigbee network layer natively supports both star and tree networks, and generic mesh networking. Every network must have one coordinator device. Within star networks, the coordinator must be the central node.
Zigbee-style self-organizing ad-hoc digital radio networks were conceived in the 1990s. 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. The library is a set of standardised commands, organised under groups known as clusters with names such as Smart Energy, Home Automation, Zigbee Light Link. Internet Protocol and will interconnect with other standards such as Thread.
Zigbee PRO, also known as Zigbee 2007, the enhanced Zigbee Pro Specification, was finalized in 2007. A Zigbee PRO device may join and operate on a legacy Zigbee network and vice versa. Zigbee network, and legacy Zigbee devices must become ZEDs on a Zigbee PRO network. The applications running on those devices work the same, regardless of the stack profile beneath them. The first Zigbee Application Profile, Home Automation, was announced November 2, 2007.
As well as running an application function, 256KB 용량의 플래시 메모리를 장착한 라디오 및 마이크로컨트롤러 통합 제품을 생산하여 판매한다. The Zigbee RF4CE team provides an overview on current status of the standard; building lighting automation through the integration of DALI with wireless sensor networks”. A secure network will designate one special device which other devices trust for the distribution of security keys: the trust center. The applications running on those devices work the same, which is used to handle configuration of new devices and establish new networks: it can determine whether a neighboring device belongs to the network and discovers new neighbors and routers.
Zigbee protocols are intended for embedded applications requiring low power consumption and tolerating low data rates. Zigbee is not for situations with high mobility among nodes. Hence, it is not suitable for tactical ad hoc radio networks in the battlefield, where high data rate and high mobility is present and needed. Established in 2002, the Zigbee Alliance is a group of companies that maintain and publish the Zigbee standard. The term Zigbee is a registered trademark of this group, not a single technical standard.
The Zigbee Alliance has three levels of membership: Adopter, Participant, and Promoter. The Adopter members are allowed access to completed Zigbee specifications and standards, and the Participant members have voting rights, play a role in Zigbee development, and have early access to specifications and standards for product development. The requirements for membership in the Zigbee alliance cause problems for Free Software developers because the annual fee conflicts with the GNU General Public Licence. The Zigbee Alliance board has been asked to make their license compatible with GPL, but refused. 0 specifications define an Internet protocol to monitor, control, inform and automate the delivery and use of energy and water. It is an enhancement of the Zigbee Smart Energy version 1 specifications.
