Zigbee protocol

Some of the technical details of the Zigbee protocol given below :
  • Zigbee offers a wireless range of 70m indoors and 400m outdoor
  • Zigbee protocol operates on a single frequency of only 2.4 GHz.
  • Low latency and low duty cycle lead to achieving low power consumption giving sensors and the long-lasting battery life
  • DSSS helps to the offers data rate for quicker response
  • Cater to thousand of devices for spread networks
  • It offers network flexibility to cover homes of all size by offering for multiple networks like point-to-point, point-to-multipoint mesh network
  • Zigbee can easily integrate monitoring and control of light systems, security system, as well as motion detection
Zigbee protocol operate 802.15.4 physical layer specification and operate even in the unlicensed band including 2.4 GHz, 868 MHz, and 900 MHz 

Different types of layers :

1. Physical layer: This layer consists of modulation and demodulation operation upon transmitting and receiving signal respectively.

2. MAC layer: This layer can be used for synchronizing communication. It is a reliable transmission of data by accessing different network with CSMA.


Different types of a layer in the Zigbee network
3. Network layer: This layer can be used for network set up, such as disconnect network, routing, device configuration, network set up, etc.

4.Application support sub-layer: This layer interface with the network layers for data managing services.

5. Application framework: This layer is responsible for detecting, initiating and binding other devices.
