| ZigBee is a technological standard, based on the IEEE 802.15.4 standard, which was created specifically for control and sensor networks. Within the broad organization of the Institute of Electrical and Electronics Engineers (IEEE), the 802 group is the section that deals with network operations and technologies. Group 15 works more specifically with wireless networking, and Task Group 4 drafted the 802.15.4 standard for a low data rate wireless personal area network (WPAN). The standard for this WPAN specifies not only a low data rate but also low power consumption and low complexity, among other things. The data rate is limited to 250 kbps in the global 2.4 GHz Industrial, Scientific, Medical (ISM) band, 20 kbps in the 868 MHz band used in Europe, and 40 kbps in the 915 MHz band used in North America and Australia. The ZigBee standard is built on top of this IEEE standard, addressing remote monitoring and control for sensory network applications. This standard was created by an organization known as the ZigBee Alliance, which is composed of a large number of companies and industry leaders striving to enable such control devices based on said standard. |
