The 802.3at PoE+ standard, also known as Power over Ethernet Plus, is an enhancement of the original Power over Ethernet (PoE) standard. This standard allows for delivery of electrical power to network devices over existing Ethernet cabling, eliminating the need for separate power sources. The 802.3at PoE+ standard provides up to 25.5 watts of power per port, nearly doubling the capacity of the original PoE standard (802.3af), which provided up to 15.4 watts. This increased power capacity enables support for a broader range of devices, including dual radio wireless access points, pan-tilt-zoom cameras, and video phones. The 802.3at PoE+ standard also includes features that enable more efficient power management and control, such as the ability to negotiate power requirements between devices and power sourcing equipment. This helps to ensure that power is used optimally and that devices do not draw more power than they need.
