Re: How is this different than regular cell phone jamming? Security-wise, wireless can be as secure as wired when properly encrypted. Critical wired infrastructure still needs to be adequately encrypted to prevent people from tapping into the wire and hijacking control.
For jamming, no miracle there... but unless you want to put a 1000km wire spool in every vehicle, hard-wiring them would not be practical  |

Who cares how secure it is because when you jam the signal, it still doesn't work. And I bet you could get a few hundred people running around with jammers in their vehicles. Think New York City and its fleet of cabs. Quite a few foreigners driving them and just enough of them with a grudge against the US could mean a very bad day for NYC. |

Most signaling infrastructure is autonomous and only needs communication to change its programming and report BIST or other results. If the communication is jammed, this is a non-issue but if it gets hacked, it can be a much worse issue so security is more important than jamming there.
Since it is not practical to wire moving vehicles, those have no choice but to use some form of wireless just like they have always been, not much of a change there. If LTE is jammed, they just have to fall back on their CB radios and punch things down by hand. If CB radio is jammed as well, they are no better/worse off than without LTE. |

Wrong, if you disrupt enough nodes, the communication system will start failing and data will move very slowly through less and less nodes creating choke points.
And how many people still use CB? Even if people had them, their range is minimal and with a bunch of people going nuts, that will become useless in minutes. |

Mullica Hill, NJ | not to mention those choked nodes could go down just from load itself. Going to guess even enterprise class routers have a fail point

kudos:1 | CB is a particular public radio band... public safety doesn't use it. They monitor it in some localities for emergencies but they don't use it for communications. You are thinking simply of 2-way radios. |

You can encrypt it, yes... but it still can be jammed.  |

Not even close. As explained, CB is a public use band.
And ask NYPD and NYFD how their systems worked on 9/11 when they lost the WTC complex. Most of their fancy digital communications were rendered useless in a matter of a couple of hours. |
