Over the next decade we will become dependent on LTE, which is why we must ensure it is secure and available when we need it. Unfortunately, like any wireless technology, disruption through radio jamming is possible. This paper investigates the extent to which LTE is vulnerable to intentional jamming, by analyzing the components of the LTE downlink and uplink signals. The LTE physical layer consists of several physical channels and signals, most of which are vital to the operation of the link. By taking into account the density of these physical channels and signals with respect to the entire frame, as well as the modulation and coding schemes involved, we come up with a series of vulnerability metrics in the form of jammer to signal ratios. The “weakest links” of the LTE signals are then identified, and used to establish the overall vulnerability of LTE to hostile interference.285 - 288 (4) page(s)enIn CopyrightTechnologyEngineering, Electrical & ElectronicEngineeringLTELTE securityjamminginterferenceArticle
