Abstract
The increasingly important role of Long Term Evolution (LTE) has increased security concerns among the service
providers and end users and made security of the network even more indispensable. The main thrust of this thesis is to
investigate if the LTE signal can be broken down in a methodical way to obtain information that would otherwise be
private; e.g., the Global Positioning System (GPS) location of the user equipment/base station or identity (ID) of the
user. The study made use of signal simulators and software to analyze the LTE signal to develop a method to remove
noise, breakdown the LTE signal and extract desired information. From the simulation results, it was possible to
extract key information in the downlink like the Downlink Control Information (DCI), Cell-Radio Network
Temporary Identifier (C-RNTI) and physical Cell Identity (Cell-ID). This information can be modified to cause
service disruptions in the network within a reasonable amount of time and with modest computing resources.
