5.6 Gbit/s downlink and 1.5 Gbit/s uplink optical wireless transmission at indoor distances (≥ 1.5 m)

We experimentally realized a bi-directional high-speed optical system working at common environment distances and illumination levels. The downlink record aggregate bitrate of 5.6 Gbit/s is achieved exploiting WDM approach, commercial LEDs and DMT modulation.
