There are many kinds of wireless communication modules in the market. How should we distinguish them? Different wireless communication technologies have been developed according to different application scenarios and user needs.
1、Bluetooth
Bluetooth is a kind of wireless communication module that we come into contact with on a daily basis. The technology was invented in 1994 by the power at that time. It is the standard of wireless technology, which can realize the short distance data exchange between fixed terminal equipment, mobile terminal equipment and personal domain network 2.4~2.485GHZ I-band UHF radio waves.
Bluetooth wireless technology complexity; device network speed, 10 seconds; integration and reliability; transmission rate is generally 1Mbps; low cost, simple installation, suitable for short-distance wireless communication technology.
2、Wi-Fi
Wi-Fi wireless technology is our daily contact with the most wireless communication technology. It is created and IEEE 802.11 standard wireless LAN technology. This technology converts all wired network signals into radio wave signals, and other terminal devices connect to wifi through wireless communication modules to realize wireless network communication.
Wi-Fi technology coverage is generally within 100 meters, the technology is complex, the transmission rate of up to 54Mbps, the working frequency band is 2.4GHZ, less than 100mw of transmit power, compared with bluetooth wireless communication, data security performance is poor. wifi invention is very in line with the needs of the modern individual and the society, the development prospect is very huge.
3、ZigBee
ZigBee is based on the wireless communication technology IEEE802.15.4 standard low-power LAN protocol in August 2001 was formally established. At the beginning of its establishment, due to the hasty version, there were some errors, and the subsequent development has been continuously improved.
ZigBee wireless communication technology is similar to Bluetooth wireless communication technology, is a short-range wireless communication technology, but Bluetooth wireless communication technology has a large power consumption, high complexity, short communication distance and other defects, only suitable for home and personal use.ZigBee technology developed to meet the needs of industrial automation, simple layout, anti-interference, reliable transmission, easy to use, low cost, communication distance from Bluetooth 10 meters to hundreds of meters, indoor about 50 meters.
4、Traditional digital transmission radio
Digital transmission radio is a high-performance professional data transmission radio with the help of DSP to achieve digital signal processing technology and software wireless point technology. Digital transmission radio can be understood as a communication medium with the same optical fiber and microwave. The transmission distance of digital transmission radio is very far, which is suitable for all kinds of complex environments, and the transmission rate is 19.2Kbps, but the cost of terminal equipment is higher, the cost of use is higher, and the installation is complicated.
