LTE vulnerable to jamming

LTE networks are vulnerable to inexpensive jamming techniques, according to researchers at Virginia Tech.

The researchconducted showed that an inexpensive transmitter and a laptop could take down the high-speed wireless data networks.

“An example strategy would be to target specific control or synchronization signals, in order to increase the geographic range of the jammer and better avoid detection,” the Wireless @ Virginia Tech research group said.

“The availability of low-cost and easy to use software-defined radios makes this threat even more realistic.”

Jeff Reed, director of Virginia Tech’s wireless research group, also explained that the vulnerabilities could be loopholes for attacks – ones which would be very difficult to defend against.

“Picture a jammer that fits in a small briefcase that takes out miles of LTE signals — whether commercial or public safety,” said Reed.
