What's the difference between AP and relay?
The difference between AP and relay:AP is equivalent to a bridge between wired network and wireless network. The main function is to connect each wireless network client together, and then connect wireless network to ethernet.Relay: a transmission path between two switching centers. A relay is a physical connection that carries multiple logical links.One of the most important functions of AP is relay.
In wireless communication, the function is to allow a large number of users to share a relatively small number of channels within a cell, that is, allocating channels to each user on demand channels from the available channel library.
AP has the function:(1) one of the most important functions of AP is relay, which means that the wireless signal is amplified between two wireless points, so that the remote client can receive more powerful wireless signals(2) AP another important function is to bridge, bridge is to link the two endpoints, the realization of the two wireless AP data transmission, to connect the two wired LAN, generally choose to bridge by AP.(3) the last function is "master slave mode", in which the AP will be considered as a wireless client, such as a wireless network card or a wireless module, by the main AP or wireless routing. In this way, it is convenient for network management to manage sub networks and realize multipoint connection. AP client is multi point, wireless routing or main AP is a little.
