The correct answer is C. high data rates.
ZigBee is a low-power, mesh networking technology designed for applications that require long battery life and low data rates. It is often used in home automation, industrial automation, and asset tracking applications.
ZigBee networks are typically used to connect a large number of devices over a short range. The low power consumption of ZigBee devices makes them ideal for battery-powered applications. ZigBee networks are also easy to install and configure, making them a good choice for DIY projects.
ZigBee networks operate in unlicensed radio bands, which means that they do not require a license to operate. This makes ZigBee a cost-effective solution for many applications.
High data rates are not a characteristic of ZigBee networks. ZigBee networks are designed for applications that require low data rates, such as home automation and industrial automation. High data rates are not necessary for these applications, and they would only consume more power and reduce battery life.
In conclusion, the correct answer is C. high data rates.
