What protocol is used in ZigBee?

IEEE 802.15.4
The Zigbee standard operates on the IEEE 802.15. 4 physical radio specification and operates in unlicensed bands including 2.4 GHz, 900 MHz and 868 MHz. The 802.15. 4 specification upon which the Zigbee stack operates gained ratification by the Institute of Electrical and Electronics Engineers (IEEE) in 2003.

What is ZigBee protocol What are three types of ZigBee explain the functions of each one of them?

Zigbee Architecture. Zigbee system structure consists of three different types of devices as Zigbee Coordinator, Router, and End device. Every Zigbee network must consist of at least one coordinator which acts as a root and bridge of the network.

Is ZigBee a communication protocol?

4.2. ZigBee is an answer for short-duration wireless communication requiring less energy consumption mainly in IoT for low-rate sensors. IEEE 802.15. 4 is the base protocol for ZigBee protocol.

What is the bandwidth of ZigBee?

1MHz
ZigBee Explained This technology also has a low-channel bandwidth of 1MHz. It’s restricted to wireless personal area networks (WPAN) and reaches an average 10 to 30 meters for usual applications. ZigBee’s data transfer speed is lower than WiFi’s, too.

How does ZigBee transmit and receive data?

In order to transmit or receive data on Xbee modules, they need to be properly configured on the same network. According to the Zigbee protocol one device needs to be in coordinator mode and the rest can be router or end devices. In this case, one device is coordinator and other is router.

How many devices can be connected to ZigBee?

Each ZigBee device has a 16 Bit short address, which means I can connect up to 2^16=65536 different devices (minus a few reserved addresses of course). Now each devices can bind up to 2^8 = 256 different services (since a few “ports” are also reserved, the maximum is actually 240 here).

What is ZigBee topology?

ZigBee supports three types of topologies: star topology, peer-to-peer topology, and cluster tree (see Figure1). Star Topology-In This Topology communication is established between devices and a single central controller, called the PAN coordinator.

Does ZigBee work without Internet?

While most popular brands are now compatible with both protocols, some only support one standard. Z-wave supports Kwikset smart locks, August smart locks, and the Logitech Harmony Hub Extender products. On the other hand, ZigBee supports Amazon Echo Plus, Philips Hue, Belkin WeMo Link, and Active Hive heating products.

How does XBee communicate?

XBee devices communicate with each other over the air, sending and receiving wireless messages. However, they can communicate with intelligent devices via the serial interface. XBee devices transmit data coming from the serial input over the air, and they send anything received wirelessly to the serial output.
