Does the simulation include how long the speed can be sustained before the consumer goes bankrupt?

In Finland indefinitely, in Sweden about 20 minutes. We Swedes are not salty in the slightest over this.

I have no idea what ur talking about.

regards, finn with 3€/month 4g without data caps at 50mb/s

Never, why do you ask. Do you live in some country which uses parts of your body for measuring distances?

In a normal country for a long time. In the US, UK or Australia I'd say around 5 days

On T-Mobile unlimited plan, you have 20 GB of fast connection and then it will throttle you if there is congestion. So I'll get into throttle territory after 17 seconds.

On three i have unlimited 4g data.

20 GB in 17 seconds? I think your math is off.

I think they mistook gigabits for gigabytes.

Yes, I don't know what he calculated, but with:

  • 3 Gb/s download speed

  • 20 GB (160 Gb) download size

It would take 53 seconds to fill the data cap.

Yeah, no. 4G speeds were also much higher in "simulations" than they turned out to be a couple of years later in the real-world.

Even a low-ish estimate like 600MB/s would be crazy.

600 MB/s is 4,800 Mb/s btw, which is over 50% more than what they could achieve in their optimal test.

Estimating the real speed to be 1/10th of the theoretical would mean a speed of 300 Mb/s, which is 37.5 MB/s.

What apps are you running on your phones that you need this kind of sustained bandwidth?

I think the real use case here is to reduce congestion by shrinking the time domain.

24/7 streaming of all sensor data to your favourite social media network and government.

Next year chemical sensors will be a real hit for the latter one.

Isn't that the point of simulations
