NXP Semiconductors created a wireless smart lighting network for the home to demonstrate the significant role of near field communication (NFC) as an energy harvesting wireless tool. Presented at the 2014 International Consumer Electronics Show in Las Vegas, Nevada, the network features EnOcean's battery-less energy harvesting switch, NXP's JN5161 wireless microcontroller and the ZigBee Green Power specification.

The EnOcean switch can be added to a home network by tapping an NFC-equipped mobile phone on the gateway to collect important network parameters, and then using the phone to pass them on to the switch. Designed by NXP, the gateway connects devices using ZigBee or JenNet-IP to the Internet via an existing home Wi-Fi router. The gateway plugs into the home router via an Ethernet port, and supports ZigBee Light Link, ZigBee Home Automation and JenNet-IP for wireless communication, as well as NFC for commissioning. Completing the demo are wireless colour LEDs and tunable white dimmable LED lamps, which can also be added to the network using NFC and then controlled via an Android smartphone.

"We're excited to be working with EnOcean and other partners in fine-tuning the overall user experience—and ultimately helping consumers to control their lighting and energy use more effectively," said Thomas Lorbach, marketing manager of RF connectivity solutions at NXP Semiconductors.

"We were able to develop a battery-less wireless switch module prototype for the first time operating a 2.4GHz radio and NFC powered by energy harvesting. Such new technologies add to EnOcean's more than 12 years of experience in energy harvesting, ultra-low power wireless communication and energy management thus enabling easy installation and exciting new use cases for our sensor solutions," EnOcean Chief Operation Officer Matthias Poppel said.

NXP has released the reference design for the 802.15.4 to Ethernet bridge, which is based on the JN5168 wireless microcontroller. The RGB and tunable white LEDs, which offer very high brightness and colour saturation, use NXP's patented sensorless sensing technology.
