The Power over Ethernet Revolution rolls on

2019 is big year for Power over Ethernet (PoE). This system for delivering power and data over twisted pair cabling is getting a big boost from the late 2018 release of the IEEE 802.3bt standard, defining PoE over four pairs instead of two. This change means PoE will be able to support more devices that require higher power. For this reason — along with the rise of the Internet of Things — more than 700 million PoE-enabled Ethernet switch ports and 280 million PoE devices are expected to ship in the next five years, according to market research firm Dell’Oro.

Why Zone Cabling makes sense for PoE in Digital Buildings

When Power over Ethernet (PoE) was introduced in 2003, it was available for only a handful of low-power operations and devices. Today, PoE is one of the fastest growing networking applications. A wide range of enterprise devices and technology rely on PoE, including lighting, access controls, laptops and desktop computers, IP cameras, information kiosks, industrial automation equipment, and wireless access points (WAPs). With the advent of digital buildings and the Internet of Things (IoT), PoE is poised for unprecedented expansion in the enterprise. To leverage the many capabilities of PoE, network designers are increasingly turning to zone cabling architectures as an alternative to traditional home run cabling in digital buildings.
