Astandardized IEEE 802.3af PoE device is able to accept both data and current via a single twisted-pair Ethernet cable on a network. In addition to simplifying cabling needs, PoE capability is highly useful in devices that may have to be placed well away from regular electrical sockets, such as wireless network access points, web-cams, security cameras, PDAs, IP telephones, network hubs, desktop computers, and video kiosks. There's even a PoE-enabled digital electric guitar, courtesy of Gibson (Nashville, TN).
