The principle of wireless network connection is to transmit data through wireless signals.
Compared with the wired network, the transmission medium of the wireless network is electromagnetic waves, and these signals are sent to the device through the wireless router, and decoded.
This is through the use of a wireless network card to connect to the wireless network, the wireless network card is connected to an antenna, through the electromagnetic wave to achieve the transmission of data.
Because of the obstruction and interference of the signal, the speed of signal transmission is affected by the environment.
In addition, with the continuous development and breakthrough of radio technology, the speed and reliability of wireless networks are also improving, and it also brings a wider range of application scenarios.
1 is the transmission of information through radio waves to achieve wireless interconnection and communication between electronic devices.
2 The transmission principle of the wireless network is to transmit radio waves through the base station or router, the device receives the signal and decodes the information, and then converts the information into a digital signal through the modem to transmit to the target device.
The development of wireless network has been very mature, covering a variety of application scenarios such as wireless LAN, cellular mobile communication, satellite communication, etc., which has brought great convenience to people's life and work.
It's the radio wave principle.
WIFI is a wireless networking technology, which used to connect computers through network cables, but is now connected through radio waves; Common is a wireless router, then the effective range of the radio wave coverage of the wireless router can be connected by WIFI connection, if the wireless router is connected to an ADSL line or other Internet lines, it is also known as \"hot spot\".
