I think "at full speed" is being taken the wrong way.
5Mhz can handle 200, 10Mhz, 400 and 20Mhz 800 (in other words 200 devices per 5Mhz spectrum).
Think about it, lets say 10Mhz gives you a speed test of around 40meg on a good day.
That's because it pretty much only you doing a constant download on that cell.
Let's now say 400 users are on the cell and all start downloading a large app.
That would require 16,000 megabits or 16 Gigabits!!!

That would mean just 10Mhz of 800 spectrum would need to carry 2000 Mega
bytes per second.!!
That would surely be very impressive!!!

No, the maximum (lab conditions) throughput of 10Mhz of 800 (rounded up) is about 75Mbps.
That has to shared between those 400 handsets.
Now remember a large proportion are going to be either doing the odd blip of background data here and there or basic low data use stuff like browsing. Your normal intermittent Internet use.
If however 80 of those people started to stream video, there would be a problem!
That's when you start to need a more dense network (so the site can push your handset to a different one) or load your sites with more frequencies (2600 / 1800).
A site with 20 of 2600, 20 of 1800 and 5 of 800 would be able to carry about 400 or more Megabits so perhaps 300 devices could stream that video.
