1. Bluetooth

Bluetooth is a wireless communication module. It is a wireless technology standard that can realize

short-distance data exchange between fixed terminal devices, mobile terminal devices and personal local area networks. It uses 2.4-2.485 GHZUHF radio wave ISM in the frequency band.

Bluetooth wireless technology is highly complex, the device networking speed is fast, only 10 seconds; High

integration and reliability; The transmission rate is generally 1Mbps; Low cost and relatively simple installation. This is a near field wireless communication technology.

2.Wi-Fi

Wi-Fi wireless technology has been throughout all aspects of our lives, which is the most common wireless communication

technology we come into contact with every day, bringing great convenience to our lives. It is a wireless LAN technology

based on IEEE802.11 standard. The technology converts all wired network signals into radio wave signals, and other

terminal devices are connected to wifi through wireless communication modules to achieve wireless network communication.

Wi-Fi technology coverage is generally within 100 meters, the technology is more complex, the transmission rate can reach

54Mbps, the working band 2.4GHz, the transmission power is less than 100mW, and compared with Bluetooth wireless

communication, the data security performance is relatively poor. However, the invention of WiFi is very in line with the needs

of modern people and society, and the development prospects are very broad.
