PoE eliminates cables by directly applying power to a host of peripherals in commercial and industrial settings.
Many different applications of Power over Ethernet, aka IEEE 802.3, or PoE as engineers like to call it, have been employed over the past 20 years, both standardized and proprietary. PoE transmits electric power along with data on twisted pair Ethernet cabling, enabling a single cable to provide both data connection and electric power to an array of devices including wireless access points, IP cameras, and VoIP phones.
