Digital Signage, Kiosks Use New PoE Standard
The new Power-over-Ethernet standard IEEE 802.3at-2009, doubling the available power to 25W is interesting in that it greatly increases the number and type of in-premises applications that can be powered in this way.
An Atom-powered processor board takes about 4W, which with the old system only left 9W max for a screen. Now that figure is increased to 21W, it opens the way for wired digital signeage and kiosk apps to be wall-wart-free.
This new technology is up and running and proving popular with our Atom-based Cinnamon Bay boards, and we’re also expecting to implement this latest type of PoE with our latest Cortex-A8-based ARM solutions where a 1W board can drive an HD screen.
