Li-fi – finally, multi-tasking my light bulb

Wi-fi has been our trusted method to connect to the internet, served us well.  However, current wi-fi top speeds are limited to the radio frequency spectrum which is becoming saturated.  So, use another spectrum I hear someone say! Genius! Why not use the visible light spectrum – well that’s exactly what engineers are doing.  The visible light spectrum has a range 10,000 times greater than the radio frequency spectrum, affording greater capacity.  Li-fi i, which has the potential (under perfect conditions) to reach speeds of up to 10Gbps, it’s a shame our internet won’t be this fast!

You may be thinking, how is this going to work? Does the light need to be on, will it be flickering on/off and what if other light sources are present?  The engineers have created this technology to operate at low levels of light and flicker at a rate which aren’t visible to the human eye, it can even be used in day light.  True, this technology is short range so you may just want to create your very own hotspot.  But the bulb isn’t the internet itself, a bulb in each room connecting to your internet may be the solution.  One upside, you don’t have to worry about your neighbour hacking on to your network and potentially running packet sniffing software capturing your usernames and passwords…

With a projected 2018 market share of $6 billion, and a much cheaper operating cost, after all the lights turned on while i’m typing this – it has my vote.  keep those carbon foot print’s down people…
