Phoronix: WiFi 6E Opens Up WiFi To 6GHz Operation

Ahead of this week's Consumer Electronics Show, the Wi-Fi Alliance has announced WiFi 6E...

Protest against 5G, aside from political games, might make sense on technical grounds.

First, it seems like protocol's security wasn't exactly amongst priorities. Rather oposite -it looks like that aspect was left with covert holes that could be exploited later.

Then there is matter of danger of HF EM waves. 5G goes wildly up the frequency spectrum, without due work on medical consequences.

It looks like someth9ng that was rushed to serve interests of few industrial names, intelligence agencies and mobile equipment providers.

It is the year 2050. WiFi 120 has just been released allowing for ultra-high performance at 120GHz frequency. It only has a transmission range of 2cm, but look at how fast Facebook loads! You can download a HD movie in 0.25s! Wow!

There should be more effort in improving the efficiency and range of the existing technology, but unfortunately faster speeds sounds better in marketing.

you mean danger of light? go back to school

What's wrong with that ? It's not like UV is not carcinogen.

And so are some wavelenghts BTW.

Above some wavelength there is enough energy to cause molecular damage.
This is known for a long time, it is nothing new or unheard of.

Wi-Fi is a complicated technology and you really have to invest time into understanding it before you can make sense of these kinds of changes.

Efficiency in Wi-Fi is about airspace. More frequency space = less contention. Faster speed = less time in the air = less contention. So all of the things you said you don't like are actually good for efficiency. You also asked for longer range, that's actually bad for efficiency as the area of a circle is pi*r^2 and you want to make r larger meaning way more circles (around each station) will be overlapping = horrible efficiency. VThe Wi-Fi Alliance article actually covers the reasons for excitement quite well if you read it.

Wi-Fi 6E will probably be the biggest real world impact to Wi-Fi since N came out. Especially since there isn't concern about having to co-exist with legacy wireless standards in this spectrum.

i've already told you to go back to school. learn how far uv is from 6ghz while you are there

how is it relevant when we are below wavelengths of heat radiation from your body?

1. Don't worry about that. visible is within 400-800nm, UV is bit below that, say 100-400nm. 6 Gig ihas wavelenght about 5cm and 100Gig is about 3mm, assuming v=c.
So what ?

2. body temperature is is in the range of tens of mEv ( 27 per Wolframalpha). 100nm photon has 12.4 eV. 100G wave has 0,4 mEv. So what ?
Phonons are obviously affecting our body differently than UV waveenghts and those are in different class than HF.
If they werent radar operators wouldn't suffer negative effects from HF radiation and there would be no security requirements, outside of obvious ones ( ie what doesn't cook you, can't harm you).

I wonder if 6E will finally make wireless ~4k VR headsets possible? that be neat. (the wires really put me off buying one of those things!)
