Since its introduction in 2002, Power over Ethernet has gradually gained momentum in the market. Today, PoE is being pushed to higher power levels, as standards and equipment are being introduced that will allow up to 71W of power to be delivered via twisted pair cabling.
The types of devices being powered via PoE continues to expand. VoIP phones represented the first wide-spread usage of PoE. Today, wireless access points are the fastest growing use, and as the appetite for wireless continues to grow, it is pushing PoE use – as well as WAP speeds – even higher. Going forward, expect to see PoE powering a wide range of devices, including digital signage, LED lighting, point-of-sale readers, nurse call systems, access control, and even vending machines.
