According to HHI, the Berlin researchers developed new building blocks which under laboratory conditions achieve data rates of up to 1 Gbit/sec. Since however in commercial LED products – that use RGB mixing to produce white light – three light colours are generated which can be utilised separately for the data transmission, the effective data rate sums up to 3 Gbit/sec.
The technology has been introduced to the public about two years ago. At that time, the maximum bandwidth was about800 Mbit/sec.
The institute did not elaborate on the properties of the new components. It however said that the modular building blocks are suitable for integration into existing wireless data communications applications; as an example the institute named car-to-x systems. In general, environments where conventional electromagnetic wireless technologies could be unfit for safety reasons, could benefit from the technology. Examples could be hospital operating theatres, exhibition halls, manufacturing halls and similar environments.
