POL
Power over Ethernet (PoE) technology has steadily increased in popularity since its introduction, and its adoption is becoming more widespread. EtherWAN developed Power over Link (PoL) technology. PoL allows power and data to be transported over a single pair of wires, and even works using traditional phone lines or coaxial cable. PoL can deliver the power needed (up to 30 Watts) to end devices such as IP cameras, controllers and access points, up to a distance of 1.2 kilometers (0.75 miles).
