In order to transfer large amounts of data from one terminal device to another in next to no time and without an interfering cable, researchers at the Fraunhofer Institute for Photonic Microsystems IPMS are working on using light as a transmission medium. Optical wireless data transmission should serve as an alternative to wired data transfer and replace established standards such as USB3.0, USB3.1, Gigabit-Ethernet or 10-Gigabit-Ethernet.
