802.3at PoE+

The 802.3at PoE+ standard, also known as Power over Ethernet PlusPlus: Plus, formerly Plus GSM is a mobile network operator providing services in Poland. The company, along with its associated satellite television company, Polsat Box, forms the major brands of Grupa Polsat Plus, the corporate group of Cyfrowy Polsat S.A. The company, Polkomtel Sp. z o.o., was launched…, 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 (802.3af802.3af: The 802.3af Power over Ethernet (PoE) standard, also known as Type 1, was ratified by the Institute of Electrical and Electronics Engineers (IEEE) in 2003. This standard allows for delivery of electrical power, along with data, to network devices over Ethernet cabling. Under the 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.
