I live in a very rural area. I am a Captain in a volunteer fire department. I have been doing this for 10 years. I have also been an EMT as well.
There is a reason cell phones are not relied on in emergency situations. An Incident Commander may use one when he is talking to the Mayor, or maybe a Hazmat specialist in another State, but he never uses a cell phone when trying to talk to someone inside the building.
Why? So everyone can hear what is being discussed. I may not be part of the conversation, but I may need to know the conditions on the other side of the building that the IC is talking about.
Dispatch also monitors the fire ground radio traffic so that they can anticipate requests for additional support. '
In the event of a major disaster at hotel property, where we might bring in specialized search and rescue teams, that we don't normally train with, such as a building collapse, Jamming of wireless signals by the hotels network is not going to be an issue. If the collapse didn't shut down the network, it will be down shortly after we shut off all power and utilities to the building.
But again, the hotels are not asking for permission to block Cell Signals. They are asking for permission to treat mobile hotspots like rogue APs, as if they are a potential threat to their wireless network. The technology to interfere with these hot spots, isn't random jamming that will interfere with Cell phone usage, or emergency radios. It is deauthentication packets aimed at the hotspots and the clients of the hotspots. It doesn't interfere with the radio environment per se, it is interferes at the layer 2 or 3 level.
It won't affect emergency communications in any way shape or form. That is a red herring.
There are lots of real reasons to dislike this proposal without inventing problems that don't exist.
