Drag the short-range wireless IoT technologies on the left to their corresponding descriptions on the right.

Answer:

Explanation:

According to the Huawei documents and resources, the definitions of the short-range wireless IoT technologies are as follows:

ZigBee: IEEE 802.15.4-based wireless communication technology is a short-range, and low-power wireless communication technology that supports star, mesh, and hybrid networking.

Bluetooth: With the emergence of IoT industries such as smart wearables, smart home, and Internet of Vehicles, short-range communication technologies are attracting more and more developers.

REID: Its basic principle is to automatically identify objects based on the transmission characteristics of radio signals and space coupling (inductance or electromagnetic coupling) or radar reflection.

Wi-Fi: Wireless networking technology based on IEEE 802.11 is the most popular WLAN technology.

Therefore, ZigBee – 1, Bluetooth – 3, REID – 2, Wi-Fi – 4 is the correct answer.
