The important role in people's lives "wireless communication"

For convenience, people are accustomed to using a mobile connection with the Internet. The wireless terminal accesses the Internet of Things through the wireless mobile communication network and can realize the functions of identifying, monitoring, and controlling the target object. At this time, the Internet of Things is called “Wireless Internet of Things”.

The Internet of Things is an extension and extension of the Internet. Various objects are combined with the Internet through radio frequency identification systems, infrared sensing devices, etc. to form a huge intelligent network. Therefore, wireless communication technology is satisfied with its rich variety and superior technical characteristics. The application requirements of "interconnects" have gradually become the main supporting technology for the architecture of the Internet of Things. It can be said that wireless communication is a powerful guarantee for the transmission of the Internet of Things.

Understanding wireless network communication technology

Wireless communication is a communication method that utilizes the characteristics that electromagnetic signals can propagate in free space to exchange information. In recent years, in the field of information and communication, the fastest growing and most widely used wireless communication technology.

With the development of the Internet, computer technology, multimedia, electronic technology and wireless communication technology, the need for information to be accessed and exchanged at any time and everywhere has become increasingly urgent. Wireless communications have begun to play an increasingly important role in people’s lives. People and information The internet is inseparable. Currently, low power consumption and miniaturization are users' eager pursuits for wireless communication products, especially portable products. Short-range wireless communication technology, an important branch of wireless communication technology, is due to its technology, cost, reliability, and practicality. Outstanding advantages are gradually attracting more and more people's attention.

The short-range wireless communication technology has a wide range. In a general sense, as long as the communication receiving and transmitting parties transmit information through radio waves and the transmission distance is limited within a short range, usually within tens of meters, it can be called short-range wireless. Communication. Its technical characteristics are: first, low cost, which is the objective requirement of short-range wireless communication technology; secondly, it is low power consumption. Compared with other wireless communication technologies, the probability of encountering large obstacles is also due to its close proximity transmission. Small, so the transmission power is generally low.
