Re: Really? This is news?
said by jp16:All wireless is subject to barrage jamming (aka brute force), where you just throw a large amount of radio energy at it. But this is not very efficient.
Maybe I am missing the point here but ANY wireless transmissions are subject to "jamming".
Individual wireless protocols may well have weak areas where a small amount of signal - but just the right signal - can be leveraged to take down the whole thing. For instance, in LTE, jamming the primary synchronization signal offers a huge multiplier of jamming effort compared with the overall effect.
I don't know to the extent that these can be mitigated by design considerations in the wireless protocols, but that doesn't mean that the research shouldn't be done.
And there's no "product" to be sold here: the researchers are from Virginia Tech and I don't believe they were paid for this work.

I'd be curious if these researchers could get access to a City's LTE network before it went live to the public - active, but not in use, to 'stress' test a real network, and see how effective this would be on a large scale.
