I didn't realize that the chip embargo was just targeting 5G. What an absurd move. It's a completely unimportant technology, why is that where you draw the line in the sand? And it's not some incredibly advanced thing that's hard to replicate, it's just a communications standard embedded on a chip. The only thing this embargo does is force China to arbitrarily build this specific supply chain entirely in their own country. Which China's rivals shouldn't even want! Having supply chains spread across dozens of countries makes it harder for all of those countries to go to war
5G is a hugely important technology. It's not just rinky dink cell phones streaming cat videos, it has massive implications for automation, like this mostly-automated port in China that uses it.
It's not just about 5g. Huawei Kirin chips used to be manufactured at TSMC on their process (which is the best in the world for ARM chips), that is not allowed to happen anymore. So Huawei had to engineer their own process for making the chips, and the fact that they're only two or three years behind TSMC now, despite all the sanctions, is incredible. They're even ahead of Google's own ARM tensor chips (which are just rebadged old Samsung designs).
I'm so sick of hearing about 5G my god why is it in everyone's mind so much? I've been able to stream a youtube video at 720 over 4g for a while now what do you need to do faster than that on a phone?? I'm a big tech nerd but this literally doesn't affect me.
It may not affect you, but it does affect me. 5G helps greatly with congestion. We have a holiday home in a skiing resort in Switzerland and during peak season, 4G is practically unusable, even 720p cat videos barely load. Last year several 5G antennas were installed around the village and I now get speeds >300Mbit, allowing me to even comfortably work remotely from there. 5G has had a very positive impact on my life.
Hey so did lenin, he hated it though
Y’all mfs are dunking on this fool but the problem and solution they’re describing is real.
Congestion reduces the bandwidth available to devices and their latency as the infrastructure shuffles packets to try and make everyone happy.
Now we might say “good, fuck em!” When those devices are tied to a ski resort for the wealthy but that same problem rears its head in dense urban environments.
Using 5g to get better volume of data in cities neatly sidesteps one of its major flaws: it can’t penetrate anything. No need to stick to bands that aren’t readily absorbed or reflected if you can just put up another radio and rely on the multi ghz handsets to filter the noise.
The whole point of America trying to limit 5g radio chips from China is to prevent the wireless enabling high density development technology from reaching the global rival that’s doing high density development.
The reason it’s radio chipsets and not processors (what the 9000 is) is that you need a fast radio ic to handle all the weird fucked up noise on the 5g band both because it’s used for everything, not just cell phones, and because the use case of a handset is gonna have massive noise anyway due to the reflectivity and absorbtion in the target band.
If you wanted to prevent a country from making effective use of wireless handsets you wouldn’t keep them from using badass arm flagship chips, you’d keep joes good radio chip out of their hands because without that their cpu is just gonna be burning cores to figure out what the hell is coming in off the antenna.
E: also, turn off 5g. All that shit about absorbtion doesn’t just apply to buildings. There’s a reason why all the military radio operators working next to huge transmitters heard voices and have a specific smattering of disorders.
Yeah, I mean, even just around big sporting events in US cities, I've noticed terrible bandwidth on cellular data. It's not a niche problem.
Your edit confuses me. Is 5G a solution or something to be concerned about?
It’s both.
On average everybody is already over the rf safe exposure limit and the high band and fr2 ranges of 5g are more energetic than the stuff we get exposed to every day with wifi.
It’s hard to learn about rf exposure effects because everyone wants to turn it into a Get the Facts situation. I worry about it because osha considers its own limits “unenforceable”.

Do you have employees by any chance?
There was no good reason for other people to be rude to your reply.
It's really useful for machines that communicate with each other
Really important in the industrial and manufacturing industry
just more bandwidth or something else about it
More bandwidth and lower latency, which is really important if you're trying to do telesurgery or controlling heavy machinery.
Because number must go up
You already have 4G so nobody can sell it to you.
The gadgets industry has to loudly proclaim the greatness of the next thing so they can get that bag. It doesn't matter whether it's incremental or genuinely transformative.
Seriously? Because 5G is how we spread covid, silly!
the de-regulation from 40 years ago means that american consumer carriers are always decades behind and that was okay until they saw that made huawaei so far ahead of them, so american the carriers employed their leverage with the trump administration to slow down huawei and it's been working; american carriers and their ecosystems brands have been catching up on the world stage to huawei since the embargo and china is doing its best to keep hauwei afloat with this new chip.
it's all of the moneyed technology focused interests in the world versus hauwei, so huawei is going to lose if china doesn't step up more; but if china does too much to keep huawei alive, they run the strong chance of pissing off more of the rich and then all of the moneyed interest in the world (tech or not) will be against china and china would lose in that situation.
China will collapse any day now
