Use ZigBee for IoT wireless networks
- [Instructor] ZigBee is the specification for the low power, wireless networks based on IEEE 802.15.4 can plan the radius developed by the ZigBee Alliance. The ZigBee is the one primary protocol based on the IEEE 802.15.4 can plan the radius. There are some key features of ZigBee networks, including worldwide and the original unlicensed ISM bands. There different unlicensed ISM bands for different uses. 2.4 gigahertz frequency band is for the worldwide users, and other sub-gigahertz frequency bands are for regional users. It also supports various network topology options, such as star, tree or mesh. It also supports network security based on AES 128 security schemes. There's some typical applications supported by ZigBee networks. For example, environmental control for heating and ventilation systems, personal healthcare, industry control and automation, home automation, for example, smart lighting, metering, access control etc., precision agriculture, for example, for core…
