What is a computer AP?

Wireless AP (access point) is a wireless switch and the core of wireless network. Wireless AP is the access point for mobile computer users to access wired networks, which is mainly used in broadband homes, buildings and parks. Typical distances include tens of meters to hundreds of meters. At present, the main technology is 802. 1 1 series. Most wireless access points also have AP client mode, which can be wirelessly connected with other access points to expand the coverage of the network.

Wireless AP (access point, wireless access node, session point or access bridge) is a broad name, which includes not only simple wireless access point (wireless AP), but also wireless routers (including wireless gateways and wireless bridges) and other devices. It mainly provides wireless workstations to access wired LAN and from wired LAN, and wireless workstations within the coverage of access point can communicate with each other through it.

A simple wireless AP is a wireless switch, which provides the function of transmitting and receiving wireless signals. The working principle of simple wireless AP is to transmit network signals through twisted-pair wires, and after the compilation of AP products, the electrical signals are converted into radio signals and sent out, forming the coverage of wireless networks. According to different power, different degrees and ranges of network coverage can be achieved. Generally, the maximum coverage distance of wireless AP can reach 500 meters. Most simple wireless AP itself does not have routing function, and server functions including DNS, DHCP and firewall must be completed by independent routing or computer.
