Cable equipment is the lifeblood of the network-everything else on the network depends on it. The antenna is the transmitter of network information and the energy of all devices, because only he can make the device work normally. Wireless network devices such as wireless network cards, wireless routers, etc. all have their own wireless antennas. There is also a unique wireless antenna. Because the antenna of the wireless device itself has a fixed distance limit, when the distance exceeds this limit, it is necessary to enhance the wireless signal through these external person lines to achieve the purpose of extending the transmission distance. Generally includes two types of directional and omnidirectional antennas.

A directional antenna is only sensitive to signals from a specific direction, and the transmitted signal is also concentrated in a specific direction.

Omnidirectional antenna can accept signals from various angles and radiate signals to various angles.

The wireless network has the characteristic of “changing wireless access points and wireless terminals as long as it is within the range of wireless signal coverage. At the same time, to add a new wireless terminal, you only need to install a wireless receiving device (wireless network card)”. It is widely used in many fields.

The structure mode of wireless network can be divided into two types: point-to-point and basic mode. Only one wireless access point, one terminal signal receiving point, and a normal computer can be set up on the hardware device. Flexible and convenient.
