Cellular Infrastructure Engineering: From GSM to 5G

This intensive deconstructs the architectural evolution of global cellular networks. We analyze the physical and logical frameworks of GSM, LTE, and 5G, focusing on high-stakes components like SS7 signaling, HLR/VLR databases, and IMSI management. You will explore the physics of signal modulation, including OFDM and SC-FDMA, while mastering the backbone protocols that govern mobile data transmission. This is a technique-heavy exploration of network-level connectivity, designed for engineers who require an unfiltered view of how mobile signals are intercepted, processed, and secured within modern telecommunications infrastructures. Bridge the gap between basic networking and cellular signal mastery.
