Took these tests at a fireworks show in Munster, IN. Dozens of thousands of people showed up and only one cell site serving the area where everyone was.
LTE crashed, EVDO held up for awhile then crashed, got knocked down to 1X for maybe 10 minutes, then halfway through the show LTE came back up, but was very iffy. First pic is right before the fireworks started, everybody was clogging up the network with their FB uploads and what not, second pic is midway through when LTE showed back up, that was the only speedtest I could do before it wouldn't connect to their servers anymore. Third photo is on the way out of that area.
I bet next year when Sprint has LTE 2500 and LTE 800 up and running this won't happen again! Text and calls worked just fine.
Curious as to how VZW and AT&T performed. I think VZW may have done the worst, they have very distant cell site spacing in this area so they may have been way overloaded before people started showing up... AT&T probably slowed down alot but kept on going, T-Mobile probably did the best. Sprint and AT&T are the two most subscribed carriers around here.
