First, I suggest you learn how to read. Once you do, come back and we'll discuss this further.
My point was that if AT&T reintroduced an unlimited data plan with no throttling, then the network would be brought to its knees. I say that because you would have many people using 100GB's of data just because they can. Unlimited usage with no restrictions is not a good thing. I do feel that they should not call it unlimited. I was not saying that congestion happens with the old unlimited data plan. That would be pretty ignorant of me to assume, considering its throttled at 5GB.
YES IT IS FACT! Your analogy is terrible. Since we're talking cell sites here, let's just skip around the lame analogies. If I am downloading content to my phone on the same tower a guy was downloading gigs and gigs (considering AT&T reintroduced some sort of truly unlimited data plan) then how would my service NOT be impacted? Of course it still could be impacted if he was on a tiered data plan. But I was strictly stating before that data usage would be impacted for anyone if someone is using 100s and 100s of gigs, even terabytes.
Now I will say this slowly (so to say) so you can understand. One's data usage is N O T I M P A C T E D in a way that is noticeable, unless that person is streaming gigs and gigs of data, crossing into the terabyte threshold on a single tower.
DO YOU UNDERSTAND? Good.
I understand. You do not.
When you experience congestion, it is because thousands of people are on at the same time as you. It has nothing to do with how long they were on before you got there or how long they will be there after you leave.
You log onto this forum at 5:00pm your time. At the same time, there are 4,000 other people in your area online. 1 of them is downloading all the porn on the internet and twirling his mustache at how he is wrecking your internet experience.
That one guy is only 1/4000th of the congestion you experience. He is doing nothing worse than you are buy checking this thread. He doesn't get more bandwidth because he is using more data. He is just on longer.
The bandwidth on his iPhone is ~20Mbits on AT&T on average just the same as yours. If he wants to download all the porn on the internet, he has to stay on the network longer, but there is nothing he can do on one lousy smartphone to somehow magically get 3,000 more people's capacity at any given moment. Therefore he (and every other one of the 4000 users on at that time, are contributing 1/4000'th of the congestion you are experiencing). If your congestion is so bad that you are getting ZERO DL speed, that means he is hitting you to the tune of 5k. That isn't even dial-up speed.
He is creating no more congestion than the guy next to you checking football scores who will only use the phone for data this one time in his entire life.
Porn guy is just on the network longer than you. When you log back into this thread at 2AM and you and he are the only two guys on the network, your phone isn't fast enough (and his isn't either) that you would use up all the band width on the cell tower and even notice each other are there.
See, total data used is NOT bandwidth. That would be like saying folks that drive more than 12000 miles a year have their cars magically take up two lanes (but paying more money for the car will magically shrink it back down).
So yes, the guy downloading all the porn on the internet is have SOME effect
on your experience, but it is a negligible amount and doubtful you would even notice if he logged off. The problem is 4000 people on one tower at the same time, not how long there were there.
Even if the one guy streams gig and gigs of data off of your tower, he STILL can't get more bandwidth than his one device can handle. He will still not get more bandwidth than the other users. He may get more data, but that is because he is on LONGER, not WIDER.
