Master the complete cellular communication stack (GSM, LTE, 5G) from theory to hands-on penetration testing. Learn SS7 signaling, network architecture, radio signal analysis, and practical SDR labs using RTL-SDR and HackRF to analyze, intercept, and exploit real-world signals.

This is the definitive, no-fluff course for engineers, ethical hackers, and security professionals who want to move beyond basic Wi-Fi and Bluetooth to master the core protocols that power global mobile communications: GSM, LTE, and 5G.

Most courses only cover the high-level theory. This one integrates deep network knowledge with Software-Defined Radio (SDR) techniques, giving you the practical ability to analyze, intercept, and understand every signal around you. If you want to master the wireless attack surface and build advanced reverse-engineering skills, this course is your roadmap.

What You Will Master: Key Skills & Technologies

• GSM & SS7 Mastery: Dive into the architecture of 2G networks, mastering the signaling protocol (SS7) used for key functionalities. Learn how HLR and VLR databases manage mobility and how this legacy protocol can be leveraged for modern attacks.

• 4G (LTE) Deep Dive: Understand the complexities of the LTE network architecture, the roles of MME, S-GW, and P-GW, and the essential differences between OFDMA and SC-FDMA. This is the foundation for analyzing modern mobile traffic.

• Core Radio Signal Analysis: Demystify the physics behind the signals. Master Modulation, Carrier Waves, and the difference between Analog vs. Digital Signals. This technical depth separates a true professional from a casual user.

• Practical SDR & Hacking Labs: Get hands-on with real hardware. Learn to configure and use RTL-SDR and the powerful HackRF One (including the Portapack). You will set up your lab environment with SDR and immediately begin detecting and analyzing real-world signals, including aircraft tracking (ADS-B).

Why This Course is Essential for Your Career

This training directly addresses the skills needed for high-demand roles in Telecom Security and Mobile Penetration Testing. You will gain deep knowledge of SS7 Vulnerabilities and LTE Penetration Testing techniques, backed by a proven portfolio of HackRF Tutorials and real-world signal analysis. This positions you as an expert ready to tackle the security challenges of 5G Architecture.
