The system, which uses pureLiFi8217;s LiFi-XC system, adjusts the bulb8217;s brightness to communicate data. This change in brightness is invisible to the human eye, but can be picked up by a receiver on the phone, which is then able to send back data using its own transmitter.

It8217;s a pretty neat system that theoretically offers 1000 times the data density of traditional Wi-Fi, while eliminating the traditional problems with interference that all wireless transmission standards experience.
It8217;s also incredibly location-specific, meaning that if you8217;ve got the system installed in an office unit in a shared building, then you8217;re not going to find your network clashing with the other offices around you.
While O2 claims that this transmission method 8220;has the potential to serve as a serious contender to Wi-Fi8221;, we8217;re skeptical this LiFi will ever be something you8217;ll actually end up installing in your home. It just doesn8217;t seem as versatile as Wi-Fi.
Even once you8217;re in the room with the LiFi-equipped light bulb, you still have to consider how the bulb is actually connected to the internet. Most modern smart bulbs use Wi-Fi or some other wireless transmission standard, although Ethernet cabling is also an option.
We8217;ll be very interested to see where O2 takes this partnership next. Clearly LiFi has its advantages, but it8217;s also got some very specific drawbacks which means that it won8217;t work everywhere.
