Modules have been developed that can transfer data, wirelessly, at up to 1Gbps over a distance of 10m. Developed by the Fraunhofer Institute for Photonic Microsystems (IPMS), the modules rely on LiFi technology: that is, transferring data using light.
Fraunhofer IPMS’ solution uses infrared light as the wireless transmission medium. Bandwidth reaches ‘several’ Gbps; data can be transferred up to 10 times faster than existing wireless solutions, says the Institute – using 15% of the energy per byte.
A LiFi Hotspot prototype will be shown by Fraunhofer at Electronica in Munich next month (stand A4.113). The module combines an optical transceiver and protocol controller with a Giagbit ethernet interface, so can be integrated into common industrial systems.

Several years ago, Samsung showed this kind of technology in backlights for displays, although we haven’t seen anything in backlights for a while. The idea of ‘narrowcasting’ data from a display without impacting other wireless signals is a good one, but requires standards to become a realistic application. (TA)
