The Institute of Electrical and Electronics Engineers (IEEE) is currently writing the 802.3bt standard, which will double the amount of power delivered to end devices. The current 25.5 W will increase to approximately 71 W, which is an increase of a factor of approximately 3. This new type of Power over Ethernet (PoE) is commonly referred to as PoE++ or 4 Pair PoE (4PPoE), and allows devices such as next generation wireless access points, security cameras with pan, tilt, zoom, and heating elements, and larger displays to operate under the new PoE standard.
