What are the types of wireless communication modules
1.ZigBee Module
Similar to Bluetooth technology, ZigBee is also a short-range wireless communication technology, compared to Bluetooth technology, there are a lot of shortcomings, such as high power consumption, high complexity, short communication distance, etc., and is only suitable for home and personal use. However, with the development of society, the enterprise's demand for industrial automation is higher and higher, Bluetooth technology and can not meet, therefore, based on Bluetooth technology, ZigBee technology was born, and the advantages are very obvious, its layout is simple, anti-jamming, high reliability of transmission, easy to use, low-cost, from the Bluetooth development of the communication distance of 10 meters, the distance of the space for hundreds of meters, the distance of the indoor is about 50 meters.
2.WiFi module
Other technologies may sound a little strange, but WiFi technology is a wireless communication technology that everyone uses every day and can't live without. The principle is that the technology converts wired network signals into radio wave signals, and the wireless communication module serves as an intermediate medium, from which other terminal devices are connected to the wifi in order to realize wireless network communication.
The range of Wi-Fi technology is generally within 100 meters, the technology is complex, the transmission speed is 54Mbps, the working frequency band is 2.4GHZ, and the transmission power is less than 100mw. Compared with Bluetooth wireless communication, the data security performance is poor. However, the invention of WiFi meets the needs of modern people and society, and its development prospect is very broad.
3. Bluetooth
This technology was invented by Ericsson, a large telecommunication company at that time, in 1994. It is a wireless technology standard that realizes short circuits between fixed terminal devices, mobile terminal devices and personal LANs.
Bluetooth wireless technology is very complex and the network of devices is very fast, only 10 seconds. Integration and reliability is very high, the transmission rate is usually 1Mbps. low cost, simple installation, suitable for short distance wireless communication technology.
4. Traditional digital broadcasting station
Digital radio station is a high-performance professional data transmission station realized by DSP digital signal processing technology and software wireless point technology. Digital broadcasting station can be understood as a communication medium with a certain range of use, such as optical fiber and microwave. The transmission distance of digital broadcasting radio is very long, adapting to various complex environments, the transmission rate is 19.2Kbps, the terminal equipment cost is high, the use cost is high, and the setup is complicated.
Finally, since ZigBee is unique as a low-rate and short-range wireless communication technology, it can be used in conjunction with a number of customized applications. It overlaps with other technologies.ZigBee applications include smart home, industrial control, automated replication, healthcare management, sensor network applications and communication applications.
