Shopping mall chain invests in powerline communications for IoT lighting

Amid all the recent talk about Bluetooth, ZigBee, visible light communications, and Power over Ethernet as communication channels for Internet of Things (IoT) lighting, it's easy to forget there's a ubiquitous infrastructure already in place that can also connect lighting to the Internet: electricity cabling. A major owner and operator of malls and shopping centers in the UK and Spain appears to see the potential in that technology, called powerline communications (PLC), which runs both data and electricity over standard 120V and 240V lines.
