LTE Wireless Jamming – Anchor Post

This post will be updated periodically with information related to 4G / LTE vulnerabilities and strengths.

A post on ExtremeTech analyzed a claim published by MIT Technology Review that LTE networks can be shut down using a “simple jamming trick” utilizing a cheap software-defined radio. Their assessment was that it would be far more difficult than implied by the authors – both in terms of practicality (large transmit power requirements) and scope (attacks would affect close range devices only – not a whole geographic area).

Nevertheless – and unsurprisingly – it appears that LTE devices may be vulnerable to specific methods of jamming, just like other common wireless systems. As always, where wireless is used for security communication, multiple paths are a necessity.
