Impact of the 2017 National Electrical Code on Remote Powering
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.
