LED luminaires transmit data at high bandwidth
Technology News |
The Heinrich Hertz Institute (HHI) in Berlin has further developed its broadband optical communications technology which utilizes standard commercial LEDs used for lighting purposes to transmit data. While hitherto data rates of up to 800 Mbit/s have been possible, the researchers succeeded in increasing this bandwidth to 3 Gbit/s.

According to HHI, the Berlin researchers developed new building blocks which under laboratory conditions achieve data rates of up to 1 Gbit/s. Since however in commercial LED products, three light colors are generated which can be utilized separately for the data transmission, the effective data rate sums up to 3 Gbit/s.

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 the like.
