Since the advent of the first Power over Ethernet (PoE) standard, IEEE 802.3af, in 2003, the information and communications technologies (ICT) industry has seen an array of PoE-enabled devices and applications proliferate commercial buildings, such as Wi-Fi, surveillance cameras, commercial lighting and sensors. The success of the technology can be largely attributed to its advantage over traditional high-voltage powering methods due to deployment via the communications cabling system. As many devices have become network- or IP-enabled, the communications cabling system that has historically been used to deliver data-only services can be used to deliver low-watt power as well. While PoE garners much of the attention and market share, there are a number of other remote power methods available.
