BBC, Li Fi 100 times faster than WiFi

(1/3) > >>

Wow, 100 times faster, that's 101 times the speed of WiFi.

Except, let's read the detail...


--- Quote ---Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).

Eh?  So, WiFi is limited to 10 Mbps.  Or at least, somebody told the BBC that it was, and they believed it, and gave that individual a huge splash of free advertising, funded by the BBC's income source, the licence payers.  :'(

They go on..


--- Quote ---It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.

Err, why does it require an Internet connection, it's only replacing a local network?  And a 'standard' led bulb, really... like the one I bought last week, that was 'standard'?   And what about the uplink, my iPad has no LED light bulb at all?

I fully understand that the BBC may find it hard to field tech savvy reporters.   But if they can't manage to find a reporter with a basic comprehension of the technology they are discussing then, IMHO, they'd be best to just abandon the story.   :(

I'm not actually opposed to LiFi, it may have niche uses - such as in the near future as high speed satellite broadband becomes available aboard aircraft, if WiFi remains banned for safety reasons.   More likely, IMHO, the aircraft manufacturers will find a way, incentivised by revenue streams, of allowing on-board WiFi after all.

Thank you for providing the link.  :)

  :thumbdown:  For the reporting.

  :wall:  Now why does my head hurt?

In fairness, since posting it has occurred to me... My IPad does of course have a light source (led I assume), behind the display.   I don't think my oversight changes anything but if it does, THAT would have been the story.  :)

If my memory serves me correct (possibly not) but hasnt li-fi been brought up and discussed on these forums before.  Possibly over a year ago, so I dont think the concept is that new.  I seem to recall it had several downfalls and although it may be useful in some instances its not ideal.

Thinking about it, I do believe that you are correct.  :)
