What is radio relay and how to use relay?
As a result of loss, the signal power transmitted on the line will be gradually attenuated, attenuation to a certain extent will cause signal distortion, and this will lead to a reception error. Repeaters are designed to solve this problem. It completes the connection of the physical circuit, amplifies the attenuated signal and remains the same as the original data. In general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media. In theory, the use of repeaters is unlimited, and the network can therefore be indefinitely extended. In fact, this is impossible, because the network standards are specific to the delay range of the signal, the repeater can only work effectively within this set of regulations, otherwise it will cause network failure.
Repeater (RP) is a device that connects network lines and is often used for two-way forwarding of physical signals between two network nodes. The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length.
Radio relay is a high power type transponder.
