The Zigbee wireless technology is globally available to address the unique needs of low-power, low-cost wireless machine-to-machine networks and the Internet of Things (IoT). It runs on IEEE 802.15.4 physical radio specification in an unlicensed band including, 2.4 GHz, 900 MHz, and 868 MHz.
Zigbee communication protocol is a robust way to use WiFi, Bluetooth, and RF-based environments. Some of the technical details of the Zigbee protocol are:
- The Zigbee protocol operates globally on a single frequency of 2.4 GHz.
- Zigbee offers a wireless range of 70m indoors and 400m outdoors.
- It offers networking flexibility to cover homes of all sizes by giving support for multiple networks like point-to-point, and point-to-multipoint mesh-networks.
- Low latency and Low Duty cycle lead to lower power consumption giving sensors a long-lasting battery life of up to 7 years.
- Direct Sequence Spread Spectrum (DSSS) helps to offer a higher data rate for quicker responses.
- Zigbee uses AES 128 encryption (government, commercial, and military-grade encryption used across the Internet), thus, protecting your information over the air transfers.
- Zigbee can easily integrate monitoring and control of light systems, security systems, convenience, and motion detection.
- The mesh-network operability of Zigbee reduces the chances of failure at nodes, and the ad-hoc routing offers better stability.
Use of Zigbee communication protocol:
Zigbee enables broad-based deployment of wireless networks with low-cost, and low-power solutions. It provides the ability to run for years on inexpensive batteries for a host of monitoring and control applications. Zigbee technology is making significant advancements in various spaces such as smart energy grids, AMR (Automatic Meter Reading), lighting controls, building automation systems, tank monitoring, HVAC control, medical devices, and fleet applications.
