New HQ connects 6000 lights via PoE

Chip giant Arm is using Ethernet for both data and electricity at its stylish four-story building. It installs Bluetooth-enabled smart building sensors too, but mounts them independent of the lighting system. True to the point that Power over Ethernet (PoE) lighting makes the most sense in new builds rather than in retrofits, British semiconductor stalwart Arm has deployed the technology across some 6000 luminaires at its recently-opened four-story headquarters annex in Cambridge, England.
