Definition: Power over Ethernet or PoE technology describes a system to transfer electrical power, along with data, to remote devices over standard twisted-pair cable in an Ethernet network.
This technology is useful for powering IP telephones, wireless LAN access points, network cameras, remote network switches, embedded computers, and other appliances where it would be inconvenient, expensive (mains wiring must often be done by qualified and/or licensed electricians for legal or insurance reasons) or infeasible to supply power separately.
The technology is somewhat comparable to POTS telephones, which also receive power and data (although analog) through the same cable.
It doesn't require modification of existing Ethernet cabling infrastructure.
