1、5G
The development of mobile communication technology from 2G to 5G has solved the communication problems between people, people and things, and things and things, and has the characteristics of high speed, less time delay and multiple connections. It is often used in industrial control, telemedicine, autonomous driving, smart cities, smart homes, environmental monitoring, security monitoring, intelligent robots and other scenarios.
2、WIFI
WIFI technology is the most common wireless communication technology we come into contact with. It has fast transmission speed and wide coverage. By converting wired network signals into radio wave signals, terminal equipment can realize wireless network communication after connecting WIFI. Commonly used in smart homes, artificial intelligence, mobile phones, computers and other electronic consumer products.
3. Bluetooth
Bluetooth technology has low transmission rate and short transmission distance, but it has strong integration and reliability, and can realize short-distance data interaction between personal LAN and fixed or mobile terminal equipment. Commonly used in the automotive field, smart medical care, wireless headphones, smart door locks, smart wearable devices and other devices.
4. Narrow-band Internet of Things
Narrow-band Internet of Things is a new wireless communication technology, which supports cellular data connection of low-power devices in WAN, and has the characteristics of wide coverage, mobility, low power consumption, low cost and many connections. It is often used in smart cities, smart water meters, equipment sharing, intelligent logistics, intelligent agriculture and other scenarios.
5、ZigBee
ZigBee is a wireless communication technology developed to meet industrial automation, which is similar to Bluetooth in short-range wireless communication technology. The difference is that ZigBee has longer transmission distance, strong anti-interference ability and reliability. It is often used in industrial control, intelligent building, remote meter reading, intelligent lighting and agricultural control.
