If that ever becomes a commercial reality I'll eat my hat. ;D

As I use a wired connection > 99.5% of the time and WiFi < 0.5% of the time, I can't see myself being an "early adopter" of that technology!  :angel:

It would stop people using there neighbors internet unless they bore a hole through the wall to get some light. :lol:
I use Ethernet cable to all my desktop and test machines, switches, access points, WiFi to our laptops and phones.

I was about to sarcastially ask What problem does it solve? as the Beeb article was unenlightening (nice pun :D)..

Then I remembered the fact that just sometimes (ie nearly always) the Beeb's technology articles  completely miss the point.  So I did a quick search...

As pointed out in wikipedia, it has advantages in electromagnetically sensitive environments, such as aircraft and some areas of hospitals, where WiFi would be unwelcome.   Which makes it much more interesting, IMHO.  :)

My work related illness was caused by the flickering lights  :-X

Films and TV depend on persistence of vision to ignore fast fluctuations. I think "flickering" is BBC people trying to explain light modulation. I doubt it is as slow as 10 bit/sec !

It does seem a bit of a niche market, light lends itself to a very narrow beam OK for Point to Point (except when it rains ! ) but in an office ? Either VERY short range (why not cable) or multipath all over.
