Light-based wireless communication is not new. It has been researched for over 50 years.
The industry did not establish itself, because it is a more expensive technology.
A major vendor from the laser industry demonstrated a system that transmits 100 times faster than any LED demo.The little computer program above is using two regular expressions.
Kyocera SLD Laser (KSLD) showed a laser Li-Fi system at the recent CES exhibition in Las Vegas in which a transmitter delivered data at 100 gigabits per second. That trounces the 1 Gbps that LED Li-Fi pioneer pureLiFi has shown.
While that’s potentially good news in general for Li-Fi, it could help hasten the end of the LED approach.
Before getting too carried away, we should note that the KSLD system transmitted only over a short distance of about a meter-and-a-half. And it utilized a boxy contraption (see photo) rather than any sleekly designed finished product. Miniaturization of a 100-Gbps product is still a few years away, although KSLD over the last year started offering a finished product at somewhere between 1 and 2 Gbps, which it makes available to systems developers for applications such as onboard Li-Fi on planes and for vehicle communications.
