This is a question from way out there off the edge, but it's something I've often wondered...
I know electronically it wouldn't be difficult to insert/create a half-second delay in communications from the visiting coaches box to the visiting bench.
So pre-game, who inspects for that, certifies the equipment and connections, and how is interference protected against once the game start
It wouldn't require a conspiracy. Coaches would never have to know about it. All it would take is a loyal, enterprising fan who works for whomever has the stadium communications contract.
Or, that one person could be slipped 5K by "the syndicate" to assure an outcome. Sadly, anything is potentially believable these days.
Communications used be more similar to what was CB radios and Walkie Talkies. Conversely, virtually all communication equipment is encrypted and essentially un-hackable or temporarily unhackable.
Temporary because each time they communicate, a different encryption key is used: meaning, even if someone had a super computer that could guess 3 trillion encryption keys per second, by the time the message is translated, a new message was sent with a different encryption key.
The term we use at GaTech is "roving encryption key" and it's unhackable in real time. Even attempting to hack is a waste of time.
You need a key to get in your house and it's been the same for quite some time, right? Meanwhile, your cellphone uses a different key every time you send a text, email or make a call.
Just to be complete, then there are VPNs, virtual private networks and what those do is set up a network that's literally virtual. It doesn't actually exist in hardware, firmware and software. It exists in software form only and is temporary and it can simulate you being in Japan or Germany soooooo well that search results will come back in those languages or if you're a NYTimes subscriber, the native display will be in Japanese or German.
The only problem with VPNs or any security system is the user. If you keep a spare key to your house under your welcome mat, or forget to lock your house, you're screwed. Same for phone security, football head set communication security or a VPN = if the user doesn't use it correctly, the user has a false sense of security and they aren't secure at all. Using a VPN correctly is difficult btw. The seller won't tell people that, but very few people know what they are doing.
BTW: because Neyland is so loud, Kirby and Beck will be using specialized equipment that will filter out any amount of crown noise and depending on conditions, the team can revert to hand signals and "Sugar Snaps" where they don't approach The Line until they are ready. Get set and go, without giving the defense ANY time to adjust.
IDK, but that's a huge hat tip to the effectiveness of the Vols fans. Fans may not like or respect Kirby, but he sure as heck respects the home fans of Neyland,
