FCC fines for jamming the spectrum are...nontrivial
Yeah if you rig up a 1kw tube amp and start splattering a big chunk of the FM boardcast band, jam their cash cow mobile networks or run around with a GPS jammer near an airport you'll get a near immediate PP slap but beyond that they'll maybe send a car eventually. They don't have the ability to detect and locate this stuff in real time and, IMO, probably shouldn't for privacy reasons.
Marriott was jamming for years, until they were forced to stop. Keyword: years.
If someone is making temporary jamming attacks (even on GPS or cell), unless you do it at your house or stationary, you ain't getting caught.
I know 'a friend at the hackerspace' who did a .25w GPS spoof to make the city look like it was in Moscow, Russia. Nobody responded.
There's lots of types of jamming, not just white noise static.
"A first offense is a misdemeanor punishable by up to a $10,000 fine and/or up to a year in jail. Subsequent offenses are felonies punishable by up to 2 years in prison. In practice, this might result in only a civil action by the FCC. But it is forbidden by Congress and can be punished by imprisonment." https://law.stackexchange.com/questions/94617/is-deliberate-....
You can fuck with RF as much as you want, as long as you A: don't do it constantly, B: don't do it in the same location every time (at home), and C: don't do it in a band belonging to someone who has their FCC field office's number on a post-it note and has paid the FCC lots of money.
The FCC told the police they didn't care, it took a bunch of HAMs running around to find the source and politely ask them to maybe fix it or at least consider turning it off if someone else complains again.
Everyone is supposed to get along and play nicely, and jamming is the definition of not doing that.
Intentionally sending disconnects/de-authentications too, if the intent is denying lawful use for someone.
Kicking in doors is also illegal.
Ideally, the operators of such venues would go and place an appropriate amount of picocells inside the stadium, but these cost a ton of money to install and they are only used maybe once a week for two hours, so there is no financial incentive for the providers (particularly if the general public has gotten so accustomed with a baseline of enshittification that they don't even protest any more).
For example, take the Munich Oktoberfest. The Theresienwiese is 42ha large and fits about 600.000 people without tents or ~200.000 in the full Oktoberfest buildout - and each year, every provider literally spins up hundreds of cells of all sizes, to accomodate the up to 20, 30 terabytes of data each day that all these people create [1]. But since that is two weeks of full load, it's worth the effort in the end financially.

I don't know why they don't bring them to sporting events and then take them out at the end. Probably labor.
It might be the word of these drivers against the stadium owners/operators, but I am still willing to entertain these accounts enough to see people perform preliminary investigations.
I would like to see signal strength maps across different times of the day and week for each of the major cellular providers in an around these venues and compare them to comparable maps for busy downtown areas.
I assume some of this data is already collected by each individual cellular service provider for their own network in order to access performance and areas of future investment.
