High Power Outdoor Band Selective Mobile Signal Repeater

Repeater is a device that connects network lines and is often used for two-way forwarding of physical signals between two network nodes. The repeater mainly completes the function of the physical layer, is responsible for transmitting information bitwise on the physical layer of the two nodes, and completes the function of signal replication, adjustment and amplification to extend the length of the network. Due to the loss, the signal power transmitted on the line will gradually attenuate. When it attenuates to a certain extent, it will cause signal distortion, and thus lead to receiving error. The repeater is designed to solve this problem. It completes the connection of the physical circuit, amplifies the attenuated signal, and keeps the same as the original data. Generally, the two ends of the repeater are connected to the same media, but some repeaters can also complete the transfer of different media. Theoretically, the use of repeaters is unlimited, so the network can be extended indefinitely. In fact, this is impossible, because the network standard has specified the delay range of the signal, and the repeater can only work effectively within the specified range, otherwise it will cause network failure.

The repeater is used to extend the network distance in the LAN environment, but it belongs to the network interconnection equipment, and operates on the physical layer of OSI. The repeater has the function of amplifying and regenerating the signal on the line, and is used to extend the length of the LAN segment (only used to connect the same LAN segment).
