Zigbee in computer networks

Zigbee is a standards-based wireless technology developed to enable low-cost, low-power wireless machine-to-machine (M2M) and internet of things (IoT) networks. Zigbee is for low-data rate, low-power applications and is an open standard.

What is ZigBee and its applications?

Zigbee is a low-power wireless mesh network standard targeted at battery-powered devices in wireless control and monitoring applications. Zigbee delivers low-latency communication. Zigbee chips are typically integrated with radios and with microcontrollers.

What is ZigBee example?

A typical example is when you have a Zigbee-enabled light bulb and a Zigbee-enabled light switch and you want the light switch to control the light bulb. With Zigbee, the two devices - even if they're from different manufacturers - speak a common language, so there's no barrier to communication.

What are three types of ZigBee?

1 ZigBee Device Types. ZigBee specifies three different device types: the ZigBee Coordinator (ZC), the ZigBee Router (ZR), and the ZigBee End Device (ZED).

What are the advantages of ZigBee?

The Zigbee Advantage

Support for multiple network topologies such as point-to-point,
Low duty cycle – provides long battery life.
Low latency.
Direct Sequence Spread Spectrum (DSSS)
Up to 65,000 nodes per network.
128-bit AES encryption for secure data connections.
Collision avoidance, retries and acknowledgements.

Why is it called ZigBee?

The name “Zigbee” refers to the zig-zag dance of the honey bees. ZigBee devices are low powered and they can communicate data over long distances by transmitting data to intermediate devices to reach more distant ones. There is no main transmitter, but rather, a series, or “mesh” of transmitters.

What is the range of ZigBee?

ZigBee is widely used to control several devices within the range of 10–100 m. The communication system is cost-effective and simple to use that any other short range wireless technology as Bluetooth and Wi-Fi (Fig.

What is ZigBee and its types?

Types of ZigBee Devices: Zigbee Coordinator Device: It communicates with routers. This device is used for connecting the devices. Zigbee Router: It is used for passing the data between devices. Zigbee End Device: It is the device that is going to be controlled.

How many devices can ZigBee support?

The parent device can't support more than 64 child devices.

Why ZigBee is better than WiFi?

Zigbee is based on the IEEE 802.15. 4 technical standard, which defines the operation of low-rate wireless personal area networks (LR-WPANs). Unlike Wi-Fi, Zigbee uses a mesh network, meaning that every node in a network is connected, which means you don't have to rely only on the router and endpoint.

Is ZigBee a software?

The ZigBee or ZigBee/IEEE 802.15. 4 protocol is a specification created for wireless networking. It includes hardware and software standard design for WSN (Wireless sensor network) requiring high reliability, low cost, low power, scalability and low data rate.

Is ZigBee a protocol?

The Zigbee protocol was designed to provide an easy-to-use wireless data solution characterized by secure, reliable wireless network architectures.

Is ZigBee Bluetooth or Wi-Fi?

Zigbee is another short-range, networking technology similar in many ways to Bluetooth LE with similar applications. It uses the same 2.4 GHz carrier frequency, consumes very little power, operates over a similar range, and offers mesh networking.

How do ZigBee devices communicate?

Zigbee smart devices communicate with each other using a radio transceiver. The chip operates on the IEEE 802.15. 4 protocol, over 2.4 GHz, which you might recognize as the same band used by Wi-Fi and Bluetooth. Unlike Wi-Fi, Zigbee has a shorter range of about 10-20 meters indoors because it uses less power.

Does ZigBee require Internet?

Zigbee uses a different frequency that doesn't compete with other devices on your Wi-Fi network, so it's less likely to affect your internet connection. Zigbee doesn't require an internet connection or router to communicate between devices.

Is ZigBee and Wi-Fi same?

ZigBee's data transfer speed is lower than WiFi's, too. Its maximum speed is just 250kbps, much lower than the lowest speed WiFi offers. ZigBee's best quality is its low power-consumption rate and battery life. Its protocol was designed as “assemble and forget”, meaning once you set it up, it can last for months.

Is ZigBee local or cloud?

Instead of using Wi-Fi and the cloud, local systems are interconnected using physical wires or such wireless methods as ZigBee, Z-Wave, and others.

What is the speed of ZigBee?

Zigbee protocol communicates signals with a 915MHz or a 2.4GHz frequency. This indicates that the speed of signal communication with Zigbee is 40-250kbps. This range is fast and supports smart and easy living applications like smart sensors and medical care.
