Silicon Windows ZURICH, July 15, 2016 - Consumer-grade LED light bulbs can be enhanced with basic light-receiving electronics to enable the sensing of incoming signals from other light-emitting devices. The enhanced light bulbs are powerful enough to establish a communication link across several meters between light bulbs and LED-only systems that can be integrated into many devices.

In the future, EnLighting may provide a practical way to connect the many devices, such as appliances, wearable devices, sensors, toys and utilities, that could comprise he internet of Things (IoT). EnLighting can support low-bandwidth communication services beyond the room via a gateway, providing the basis for applications such as a location-based service.
