Power over Ethernet is a simple way of providing power for an access point on the roof. Passive PoE uses free wires in the Ethernet cable and sends the equipments power along them to the far end. Over a short distance, its usually possible to use the power adapter supplied as standard with the access point or with other network elements which we wish to connect along the Ethernet cable. If the loss of the voltage on the wiring along longer lengths of Ethernet cable is too high, its possible to use another more powerful power adapter, to eliminate this loss of voltage.
