Zigbee is a type of wireless technology designed to offer inexpensive and low-power wireless connections to IoT networks. As opposed to traditional Wifi, Zigbee carries out small quantities of data within a short distance. Due to this, the technology requires less power than modern wifi technologies. Even though it has been out for over a decade, not many people are aware of this technology. The cause for that may be because of the lower data-transfer speed. However, devices such as smart home sensors and low-powered devices do not require a lot of bandwidth which makes the Zigbee a perfect device.

The standard Zigbee operates on a radio specification of IEEE 802.15.4 and the bands that are included are 2.4 GHz, 900 MHz and 868 MHz. These devices are restricted to only wireless personal area networks because they can reach a distance of only 10 to 30 meters. The maximum speed of data transfer with Zigbee devices is 250kbps which is much slower than traditional Wifi. Luckily, because of the low power consumption, the battery life is much better and lasts a long time. Users have to set up the device once and not worry about replacing it for a while. Zigbee is designed in a specific way where each node in the network is connected with one another. The problem with this is that the nodes can interfere with one another because they are using the same Zigbee chips. Hence, they will not be able to operate with one another.

The applications of the Zigbee include broad-based deployment which is very useful for companies that require many devices that need wireless networks. Many companies opt for these devices because theta re low-cost and consume less power than traditional devices. Since they consume less power, the devices will be able to run for many years and can monitor and control the applications used. Zigbee devices can be found in tank monitoring, automation systems, medical devices and HVAC control. Since our world is merging with technology and more smart home devices are being invented, having Zigbee devices can be very helpful. For example, in a household, since most of the smart home devices are clustered together in one area, this will be perfect for Zigbee devices.
