Li-Fi history

Li-Fi technology is not an entirely new invention. Light signals (infrared) has been used since the 80s of last century, mainly in TV remote controls. The real breakthrough was achieved during 2011, when the first Gigabit-class Li-Fi was developed. The Fraunhofer IPMS and IBSENtelecom have been in the front line of this new development.

GigaSpeed

Optical wireless gigabit-class data transmission was demonstrated the first time in 2011 in the Gigabit Optical Wireless Communications Workgroup of the Infrared Data Association (IrDA).

3 + 5 Gigabit/sec

Later in 2012 and 2013, a 3 Gbps and thereafter a 5 Gbps data transmission rate was demonstrated as proof of concept for a secure and stable high-speed optical data link. The mentioned feasibility studies were conducted over a range of about 10 cm in the labs of the Fraunhofer IPMS.

Connectivity

Fraunhofer IPMS built a prototype in 10/2013 and demonstrated successfully a high-speed optical wireless data transmission with a connected Ethernet (GigE) plug.

10 Gigabit/sec

In a second feasibility study from early 2014, optical wireless communication was demonstrated by the Fraunhofer IPMS with a USB3.0 connection. In June 2014, followed an optical
wireless link with 10 Gbps, also done by the IPMS.
