Anonymous, 31 Jan 2020"once again...." since when the copy cat country ever been infront ?They have nearly 90% coverage for 5G ... How many countries can match that?
So they're leader in 5G. Your hatred isn't going to change that.
My country isn't even 50% coverage for 4G yet.
Who's writing this ignorant and shallow ad piece?
"Again"? *Again*, China is not ahead in 5G, by most metrics, unlike what some conspiracy theorists claim.
6G is pure vaporware, seeing how 5G still can't even break 2Gbps in lab conditions with a theoretical speed limit of over 10Gbps of the hardware already deployed for commercial use. We've been approaching Shannon's limit since 4G, and 5G not to mention 6G provides rapidly diminishing returns in quantum efficiency. There is a limit, it's a hard limit, hard as a wall unless quantum entanglement makes a breakthrough or something so we can bypass EM radiation based wireless communication altogether.
5G's gains mainly rely on wider bandwidth, which mandates higher frequency, which unavoidably results in higher signal loss to be made up for with...essentially brute-forcing the antenna number, as well as the number of basestations. Go any further and we might as well just use visible light where we already have Lifi, where there's plenty of obstruction, negligible diffraction and you'd need a straight line of sight from every terminal to a basestation.
Other "tricks" in 5G like massive MIMO also rely on bandwidth and brute-forcing the hardware, but Wifi's massive MIMO has a better track record IRL. You could enjoy Wifi6, in your home, in your office right now with a fairly priced router/AP, and get speeds matching 5G for a fraction of what a 5G contract asks for. The hardware is just cheaper and there are far fewer patents to license. Using multiple APs with the correct firmware already provides coverage over a range of hundreds of meters, again, 5G level performance without 5G price. Go any further and 5G won't be economic to deploy, or they'll fool you with the "really low bands", which while technically 5G, is in 4G speed territory, because they don't have enough bandwidth at the low frequency required for their coverage.
Anonymous, 31 Jan 2020they are more concern on 6G than solving how to stop the corona virus to spread?A lot of people in China. Some work on 6G, some on new virus.
Is this another high frequency gimmick like 5G has? Maybe they can put it in the 4+ Exahertz range to REALLY improve signal penetration. It would finally end the argument over whether or not cellphones cause cancer by making it a definite "yes."
RealLifePhones, 31 Jan 2020With LTE the theoretical max promised is 1 Gbit/s --> real world max 30-50MBit/s
With 5G N... moreIt depends on a lot of factors. Of course the figures pushed by IP holders, network equipment sellers and ISPs are blown out of proportion to attract gullible consumers and investors. Here I have nearly 300Mbps on LTE-A. But then again I'm not in a very densely populated area and it wasn't raining or snowing or anything.
It's really a game of hype. And also a race to find new reasons to push new and more expensive tech to people. See how they heavily rely on "AR/VR" or "8K Streaming" or "5G Smart Cities" for 5G, despite the irrelevance of these things (and the existence of LTE-M for smart IoT)?
If only China worked as hard on virus prevention and quarantine as they to on tech
Anonymous, 31 Jan 2020"once again...." since when the copy cat country ever been infront ?From 5g onward.
its not like we have a consumer grade storage device that has that kind of read/write speeds
No worry Trump will ban again and again the great Chinese tech and wait 3-4 years the US companies to catch up :)
we still don't have a stable 4G in my shithole country in the first place.
Well the richest people of the world will cause a doom on us. Becaause for the greed and more money they swill igniore the fact that the human life is more precious than money.
But for people who have enough to buy even the universe it self we are just single penny each of us which have practicaly no value.
And when there will be no ordinary people we get replaced with robots which will not need or use the money so the rich people gets even richer, And this will continue on and on untill only robots remains with no living human.
Just predicting the future.
No need to thank me.
"once again...." since when the copy cat country ever been infront ?
CrazyYo, 31 Jan 2020Yeah and to have 6g to work out all you need is a network tower attached with your phone. Bingo.No man we all will carry a backpack with a 6G tower inside :-)
This is Just on paper
4 g was is Not more then 250 MB
5 g Not more then 750 MB
Anonymous, 31 Jan 2020they are more concern on 6G than solving how to stop the corona virus to spread?it's similar to SARS from 2003. So if people researched it throughoutly, then there would be almost ready vaccine for coronavirus. But as everyone knows people only care for making money, so don't complain. This course of action was predictable.
