In a facebook post from today, Mark Zuckerberg, Founder and CEO of facebook has revealed that Facebook's Connectivity Lab is developing a laser communications system that can beam data from the sky into communities. According to Zuckerberg "This will dramatically increase the speed of sending data over long distances."
In his post, Mark indicates that "Normally you wouldn’t be able to see the actual beams, but for this demonstration we made them visible." The reason that you wouldn't be able to see the actual beams is due to the fact that lasers for communications are not in the visible range. The visible range includes wavelengths between 0.4 to 0.7 microns. Wavelengths above the visible range are in the Infrared and microwave range and cannot been seen by the human eye. For the demonstration Facebook Labs made use of visible lasers.
