Internet network booster from Grandstream company with PoE Injector. New, very light use, not even a full day. Reason for selling: no longer needed and bought in a hurry. It provides wider coverage and stable connection, and reaches further than most other boosters. Suitable for home and commercial use. Connection Method: The PoE device is connected to electricity, then a network cable is connected from the main router to the PoE, and then a small network cable (the one shown in the picture) is connected from the PoE to the booster to power it and transfer data through the same cable.
