WIFI how does the repeater amplify the amplified signal?
If the intermediate relay equipment increase the routing function, and the upper device is not in the same broadcast domain, then it can not be called relay, although they play the role of increasing the distance, but it is rigorous added a wireless router, and can not be said to be a relay, the user can feel the IP address is changed, the SSID name and password for wireless contact also changed.
The realization method of wireless relay is to increase wireless devices, by the relay to the host device to transmit signals, the increase of transmission distance, intermediate relay equipment after more mobile terms called micro cellular system, because no routing relay equipment and DHCP and other more than three layers, is also transparent to users. Is that users feel like intermediate relay equipment, or connect to the same device, through the relay to amplify the signal distance, avoid attenuation.
Like repeaters in old Ethernet, repeaters in old token ring networks have the same principle: signal reduction and amplification.As long as the signal is generated by electricity, whether wired or wireless or waves will have an attenuation and distortion, attenuation is due to the distance from the distortion of interference, attenuation is inevitable, the distortion can be avoided or improved.
