said by j1349705:Jamming the communications networks would be secondary to a primary attack (the big explosion)... just a way to create more chaos and slow down the response. That's why there is concern over emergency communication networks moving to a technology that may be more vulnerable to attack. At this point, however, it is too soon to tell if this is a significant threat or not.
Couldn't a country potentially use low earth satellites to shut down large areas of LTE? From the device specification, not a lot of power is needed.
Imagine China shutting down most US and European cell functionality concurrent with a move somewhere? Or worse, a country like Iran or North Korea jamming U.S. cellular as an annoyance / provocation. Taking out low earth satellites is within our capability, but it can be messy and can cause issues for years with regards to future launches (more debris in space).
It isn't just a non-national group of terrorists who could exploit this.
Maybe LTE needs to be rethought if possible, to tighten it up against the identified weaknesses.
