Product Name: POE Injector / Splitter To achieve optimal performance of a Wireless LAN, the location of the Access Point (AP) must be carefully chosen. In many cases, finding a power supply for the AP can be a common challenge. Power over Ethernet (PoE) technology provides an efficient power solution to help overcome these challenges. In Ethernet, four pairs of Cat5 or Cat5e twisted pairs are used as the transmission medium. However, actual data transmission only uses four wires (pins 1-2-3-6). PoE technology utilizes the remaining pairs (pins 4-5 and 7-8) to conduct power.
