Abstract: Power over Ethernet (POE) can be converted into a USB stream and separate power. With these techniques, the benefits of POE can be obtained without requiring a terminal to be POE-enabled and without employing a terminal's Ethernet port. Many more terminals may therefore be powered via POE.
