Product Name: POE Injector / Splitter 1.To achieve best performance of a Wireless LAN, the location of Access Point(AP) must be carefully chosen.In most cases, finding a power supply for AP is a common obstacle. 2.Power over Ethernet(PoE) technology provides the perfect power solution to help overcome these obstacles.In Ethernet, four pairs of C5 or C5E twisted pairs are used as the medium for transmission. The actual data transmission, however,only takes up 4-pairs of wires (pairs 1-8). PoE technology utilizesthe remaining pairs (pairs 4-5 and 7-8 to conduct electricity.
