Zigbee is an 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, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
An 802.15.4 radio module is a small device used to communicate wirelessly with other devices according to the IEEE 802.15.4 protocol. This table lists production ready-to-use certified modules only, not radio chips.
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB. Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". Nodes ...
Its goal is to facilitate interoperability among smart home devices, mobile apps, and cloud services, employing a specific suite of IP-based networking technologies such as mDNS and IPv6. [26] By adhering to a network design that operates at the Application Layer of the OSI 7 layer model , Matter differs from protocols like Zigbee or Z-Wave and ...
Products released before 2019 use the Zigbee Light Link protocol, a compatible subset of Zigbee 3.0, to communicate, while lighting products released later use either Bluetooth or Zigbee 3.0. Smart switches, motion detectors, and other accessory devices such as the Hue HDMI sync originally used only the Zigbee Home Automation protocol, but ...
Wi-Fi – Technology for local area networking–based on the IEEE 802.11 standard, where devices may communicate through a shared access point or directly between individual devices. Zigbee – Communication protocols for personal area networking– based on the IEEE 802.15.4 standard, providing low power consumption, low data rate, low cost ...
The relationship between IEEE 802.15.4 and Zigbee [8] is similar to that between IEEE 802.11 and the Wi-Fi Alliance. The requirements for membership in the Alliance cause problems for free-software developers working with Zigbee because the annual fee conflicts with the GNU General Public Licence. [9]
