Wireless Network Technology Application Introduction of wireless network devices

A wireless LAN consists of a wireless network adapter, AP, Wireless Bridge, computer, and related devices.

1. Wireless Access Point (AP)

It is a bridge between a wireless LAN and other wired networks. In this way, any computer or network device with a wireless network card can share the wired network with network management functions through AP, and manage the computer with a wireless network card.

2. Wireless Bridge

The function of a bridge is to provide a wireless link for communication between two points. Two or more wireless bridges can be used to connect the local networks separated from each other.

3. Wireless Adapter

Currently, the specification of a wireless network adapter can be roughly divided into PCMCIA, PCI, USB, CF, and other interface models.

4. Antenna

Antennas must be used for wireless network interconnection. Based on the features of the antenna, it can be divided into a targeted antenna, an omnidirectional antenna, and a fan-area antenna, which are suitable for point-to-point, point-to-point, and area coverage respectively.
