Yeahbut, at a big/busy airport you'd gain or drop 300-500 connections at a
time every minute or so. Not only are there a lot of connections they rise and
fall "all of a sudden" as a plane arrives or departs.
At a sports venue the ramp up or down would slower, although still pretty darn
fast.
I guess during high traffic times the demand at an airport would be pretty
steady with just individual connections changing in/out.

Go look at a major sports venue, like a large football stadium.
I saw the engineering for WiFi and cellular infrastructure for Raymond James
Stadium (Buccaneer’s football stadium, this year’s Super Bowl location) a
couple of years ago, since the County owns the stadium and leases it back to
the Buccaneers. Mind boggling. It was designed to handle over 50,000 concurrent
connections when I saw it, and one of our network guys was telling us a couple
of weeks ago that they’ve increased the capacity since.
The cellular providers have local cells within those buildings in most cases. I
know at TPA there are about four cells belonging to Verizon on site, and
they’re all within the buildings. They can manage the loads far better in that
kind of environment, as the cells are set up to load balance. These are known
as “picocells” or “femtocells” that backhaul on a local fiber network to gain
connectivity and manage traffic.
For temporary use, all of the major cellular companies have portable sites
they’ll bring in to augment existing infrastructure. You’ll probably see some
of these in the news over the next few week in the areas where hurricane Laura
ravaged the infrastructure. Think of a large mesh network.
