Disruptive optical mobility technology

fly eye receiver

The extended mobility concept of the Li-Fi Consortium is based on state of the art optical receiver chip technology. The architecture of the optical receiver chip is based on a biological design: The eye of a fruit fly. The fly eye design has a revolutionary architecture and impressive capabilities. It uses an optical sensor array, which is faceted like a fly’s eye. It has a wide field of view, implemented with multiple narrow fields of view elements. It is able to read reflections of light and overcomes with that the limitations of the typical optical Line-of-Site connectivity. The chip is able to identify the signal (+ transmitter) position in both angle and range.

With this development, mobile devices do not depend on a line of sight connection between sender and receiver. Fly eye receiver chips will be able to read reflections, also of very weak signals. Its large dynamic range is the basis of our mobility technology. The chip supports multi-channel high-speed communication while also tracking the transmission source electronically, with no moving parts. This enables “communication on the move”: That is a moving transmitter communicating with a fixed or even moving receiver.

This technology has been developed to concept stage and needs investment in chip development.
