What is the 7G network?
So far, the 7G network has only been a figment of our mind, but it is a sign that we have come to accept that development will continue and that something new will emerge. I wrote a post two days ago suggesting that 6G will become a reality around 2035 and how fast is 7g internet, implying that people will begin to use it.
Of course, I’m anticipating lab demonstrations and testing well ahead of time, as was the case with prior Gs and is currently the case with 5G.
About 7G network
Nonetheless, one of the many responses I received said unequivocally that 7G (yes, 7, not 6g) would be accessible in 2032. Regrettably, the comment did not specify on what grounds the prediction was made.
How fast is 7G internet?
As we do not have a 7G network at that moment so we can make predictions like that,
5G speeds will range from 1 to 10 gigabits per second, implying that 6G must deliver speeds of 100 gigabits per second to 1 terabit per second, and 7G will deliver speeds of 10 gigabits per second to 100 gigabits per second.
7G speed will be ten gigabits/s to 100 gigabits/s.
Is it reasonable to expect a 7G network to occur in the next 13 years?
Looking back, I can see excellent linearity in Gs’ progression (time-wise):
we have a ten-year gap between 1G and the next, both if you take the first experiments, the first deployment, broad market uptake, and even its demise as a reference frame.
Where is the 7g network in the world?
We should expect 6G in the 2035 time frame and 7G in the 2045 time frame. We will have actual mass-market adoption of 5G in the first half of the next decade (I put 2025 as the point where most everyone will be able to own a 5G device and get access to a 5G network -and I consider this to be an ambitious target).
Which country using a 7g network?
7G network available in which country?
Norway Is using the fastest network speed, so we can say that Norway uses a 7g network and 8g networks.
On the other side, some people, such as Ray Kurzweil, make predictions based on the law of accelerated returns, claiming that evolution is speeding up and that what used to take ten years will now take seven, then five, and so on.
I’m guessing that based on these accelerated return assumptions, you’ll go from 5G to 7G network in 12/13 years, which could explain the comment (I hope the one who made it will come forward with some substantiation, always nice to hear different viewpoints).
The law of rapid returns, in my opinion, does not apply to infrastructure. This is a domain where economics steers evolution, with technology serving as a facilitator. Furthermore, the demand-side economic engine is weakening, and the entire infrastructure is outpacing the needs of customers and users. In a bit, I’ll expand on this.
Reasons that I don’t believe in Gs and How fast is 7G internet?
There are other reasons why I don’t believe we’ll see a significant increase in new Gs and How fast is 7G internet is.
When you consider the fundamentals of wireless, you’ll see that the primary technology engine for progressing from one G to the next (7G network) is the evolution (growth) of computing capabilities, accompanied by a rise in battery density (capacity). This latter, however, cannot continue indefinitely (even though there is still plenty of room to reduce the need for power in electronic components – the Landauer limit is still 100 years away-) because as power use grows, so does power dissipation. You won’t want to hold a red hot brick in your hand.
The growth in processing capacity allowed for the usage of higher and higher frequencies;
with 6G, we may enter the THz space, but the processing capacity increase is currently leveling when looking at a single chip. You don’t want many chips in mobile devices because they won’t fit in the slim cases we’ve come to adore, and they’ll boost power consumption. Processing capacity will continue to rise for a few more decades, although at a slower rate (the areas of GPUs were an exception to these rules, but that was the result, primarily, of parallel processing).
So there will be evolution on the technology side, and the law of accelerated returns may compensate for the slowdown of technological change in the processing area, allowing us to sustain the pace we’ve observed thus far. I don’t think it’ll be able to keep up at that rate.
Economic factors
Now let’s return to economic factors. As we increase the frequency (because of the growing processing capability), we run into problems with propagation. We’re obliged to either grow the wireless power (which regulators won’t allow because it would reduce battery life) or shrink the cells. The latter is what must occur.
The issue with smaller cells is that the investment at the edges must be increased. Suppose you want to achieve the 7G network capacity potential while covering the same region. In that case, you’ll need ten times as many antennas as you did with 6G, which entails a significant infrastructure investment (in antennas, optical fiber drops, and space rent).
