Hot Selling CDMA 800MHz Single Band Selective Pico Repeater 2g Mobile Signal Booster

The repeater works at the physical layer of OSI and is the center of all nodes on the LAN. Its function is to amplify signals, compensate for signal attenuation, and support long-distance communication. Repeater. Working in the physical layer, it only plays the role of extending the transmission distance and is transparent to the high-level protocol. In fact, the network connected by repeaters is equivalent to a larger network composed of the same wire. Repeaters can also connect networks of different transmission media (10Base5 and 10Base2) together, and are often used in the interconnection of the same LAN above the data link layer.

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.
