This standard allows electric power to be sent along the same cables that carry Ethernet data. PoE-enabled switches and controllers can now deliver power over standard Category 5e or 6 Ethernet cabling to remote PoE-enabled devices such as IP phones, WLAN access points, security systems, and RFID scanners. PoE simplifies the deployment of literally any IP-based device, particularly in areas where it may be difficult or expensive to run separate power cabling.

Final approval of the Power-over-Ethernet (PoE) standard in June 2003, removed a significant barrier to widespread adoption of IP telephony. The standard (IEEE 802.3af) specifies how to supply power to compliant devices over Ethernet LAN cabling. Armed with uninterruptible power supplies (UPS), IT staff can now deploy Voice over IP (VoIP) telephones without worrying about them not functioning during a power outage. The benefits of this enabling technology extend beyond IP telephony.
