I think slashdot (of all sites) had a important snippet why this is important news:
> This information comes from research carried out in the U.S. into the possibility of using LTE networks as the basis for a next-generation emergency response communications system.
I can agree that "civilian" systems can except people to behave in a non-destructive way. But a law-enforcement/emergency system should be reasonably resilient (of course not immune, but resilient) against interference. Thus the value of this study is that it exposes that LTE is not suitable for such use.
The current law enforcement/public safety system (P25) is even worse than LTE on many metrics -- it's easy to jam AND fails open/insecure due to both protocol and radio UI/UX problems. Matt Blaze, Perry Metzger, et al. found a bunch of crazy problems with it and have done talks for the past couple years.
