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.
