6G could be 8,000 times faster than 5G with speeds up to 1TB per second

6G could be 8,000 times faster than 5G with speeds up to 1TB per second

Not bad! 

China already started working on it, but it seems Japan it's in the race too.

We should see 6G in 2030 ( or around ).

Seems Game Streaming Services will explode in that period. They will when 5G will have solid roots, but imagine 6G speeds. 

Ready Player One will be achievable with 6G speeds, but yea, only on Gaming Streaming Services.

Thoughts ?

If they mean transferring that kind of data wirelessly, then there are some serious physics problems to solve.  I could believe that they could do it in a pristine environment where they have the entire spectrum all to themselves with no interference or multipath.  That's not a very good description of cellular networks, though.

If they use the sort of relatively low frequency spectrum that cellular networks have traditionally used, there just isn't enough spectrum.  You canonically only have 6 GHz of spectrum below 6 GHz, and no amount of encoding tricks is going to get you to 1 TB/sec in that amount of spectrum, even if you had it all to yourself, which you don't.

Once you go to the mmWave chunk of spectrum, which 5G can do but usually doesn't, the signal just doesn't propagate very well.  That means you're limited to short distances with pretty clean line of sight.  That's fine for stuff like stadiums where you have many people packed very densely.  But it's very short range and much less versatile than what you're used to with 4G or 3G.  And even that doesn't have enough spectrum to make 1 TB/sec viable.

Above that is the terahertz range, which would be extremely short range because it promptly gets absorbed by the air.  Past that, you get into infrared and visible light, where you would have plenty of spectrum, but lots of other problems, such as needing perfect line of sight.  You can transmit a ton of data in a hurry in the visible light spectrum in a pristine environment, such as inside of a fiber optic cable.  But that's not wireless.

This are all valid points, as we speak! Same as it was for 5G .. 10-15 years ago? 15 years ago  we didn't even had SmartPhones, let alone thinking we can have download speeds on our phones as fast as 4G, let alone 5G ! 

Yes, they need to solve some .. physics problem, but history is on our side!  

This speeds I agree, will not "affect" us, because let's face it, 1TB/s is ... pretty much useless for usual consumers, but for technology ( any ) , will be very, very good!

The radio frequency spectrum is what it is, and its propagation properties have been known for a long time.  So no, there was never a "there isn't enough spectrum for 5G to work" problem.  There was only a "radios can't handle all of the sampling and encoding tricks you'll need yet" problem.  There probably will be a 6G, and it will work fine.  It just won't be anywhere near 1 TB/sec.

For comparison, if there had been a generation of tools that sent data at 1 million m/s (linear speed, not bit rate throughput), and then another at 10 million m/s, and then another at 100 million m/s, someone ignorant might claim that the next one would go at 1 billion m/s.  But they'd be wrong, as physics gets in the way.  You're not going over 299792458 m/s.

I could believe that there will be future network connections that go at 1 TB/sec.  But they'll be wired, not wireless, unless people develop some technology totally different from using the radio frequency spectrum that wireless connections use today.

1 TB per second.  Damn.

It's possible. You just need to use a death beam.
