The essence of a wireless bridge is to convert Ethernet signals into directional Wi-Fi signals, which are then received and converted back into Ethernet signals at the other end. The entire process requires almost no human intervention, and the principle is as follows:
1. The A-side bridge connects to the main router;
2. The A-side transmits the signal to the distant B-side via a directional wireless frequency band;
3. The B-side receives the signal and converts it back into a network output, connecting to computers, switches, or other devices.
Both ends require a clear line of sight, meaning there should be no walls, buildings, or other obstructions in between. The maximum range typically extends from several hundred meters to tens of kilometers, depending on the device power and antenna specifications.
