Possible use of power LEDs for lighting and communication

Abstract

Over the past decade rapid development of communication technology happened in the field of optoelectronics. At this time metallic lines are no able to transmit large amount of data such as optical fibers. Practicallyall backbone communication networks are built on optical fibers, whereas it can be expected a their significant role in the last mile networks. As an alternative to last mile networks it could take the so-called free space optical networks (FSO), whether the indoor FSO or outdoor FSO links (point-to-point). The development of power LEDs enables to use these components for lighting the space and together as an optical transmission point in indoor FSO. This article is focused on experimental verification of the possible use of power LEDs for simultaneous wireless communication and lighting of room (spectral and radiation characteristics depending on the OOK modulation).
