Function: It extends the coverage area of your existing Wi-Fi network by receiving the signal, amplifying it, and then re-transmitting the boosted signal.
Placement: For optimal performance, it should be placed in an area with just enough existing Wi-Fi reception to effectively receive and re-broadcast the signal.
Benefits: It helps eliminate Wi-Fi dead zones and improves signal strength in areas where the router's signal is weak, like different floors or far corners of a home or office.
