So no one should ever test anything that is faster than what we currently have, because we can't use it yet, right? If that were the case, we'd all be on dial-up 28k modems still. If that.
You're curious about it, yet you provide an answer. How is it that you already know the answer, and if you already know it, then why are you curious about it?
It doesn't make it useless, it just means that these are issues that have to be considered. I can already think of one work around - have a wifi that kicks in when the lifi drops out. The lifi would still be preferable speed-wise when its available, and the user would still have a connection when it drops out.
And no one had gigabit connections when we were using 28k modems. You do realize technology improves over time, right?
As technology improves, people make use of it. You seem to be criticizing that they are thinking of potential uses for it, and how technology may change. Seems a weird thing to criticize.

A common these here at JT. Every time a new technology is discussed, people jump in to say how it will never work, and recite a list of problems, as though they are the first to think of them. And as though the 100s of qualified engineers and scientists have never considered those problems. And as though problems are never overcome, and what we have is the best we will ever have (even though we didn't even have that 10 years before).
What a dreary way to live.

as usual totally crap info inserted into articles. there is no way in heck that apple would suddenly add unproven, and such limited, technology to its premier product. perhaps they meant to say samsung which always adds bells and whistles to try to outdo apple, but i think even they are smarter than that.

Except for the 1000s of news reports saying otherwise, you might be right. Apple will soon be integrating lifi according to most experts.

Sounds cool.
So only if those 23 DVDs are in line of sight?

This is honestly one of the most flawed articles I have ever read.
Great, except nobody has internet speeds near that in their homes, heck, I doubt most people could even fully use 802.11ac.
I'm curious what happens if you have 2 'Li-Fi' routers on the same frequency. answer: clients are unable to receive data, as it completely scrambles it.
This isn't just a drawback, this is what makes this technology almost completely useless, e.g.; You are streaming music, then put your phone in your pocket before it finished downloading, music will stop playing as the connection is gone. Now you would probably say "but with 200gbps it will download within milliseconds", again, I doubt anyone has a 200gbps connection into his home.
This is perfectly possible with Wi-Fi, yet I see nobody doing this, what makes them think this technology will suddenly get supermarkets of their asses, make apps for the phone, then install Li-Fi hardware beside the Wi-Fi hardware they might already have.
Or just place a WiFi router, would have the same effect.
Now, don't get me wrong, it's a really interesting idea and there are probably cases where it could be useful (e.g. the hospitals). But claiming it is a replacement for Wi-Fi is just some weak argument to get more money out of the pockets of consumers.

Right. I guess it makes them feel better to criticize, rather than to be excited about the new possibilities.

You have a point, but you must agree that the article is written in a way that is likely to cause a cynical response in grumpy old gits like myself. It's not going to replace wifi for general use. It's unlikely to revolutionize our lives. It has features that make it suitable for particular applications. It would have been better if those were more clearly described.

We're still waiting for WiGig to be widely implemented

Can we please bypass the useless, parasitic telcos?

This is so astonishing, I almost suspect a hoax, a la cold fusion and that car in Osaka powered by water.

All the walls inside a house can be made of glass and it should work.
