Talk: From Noise to Knowledge: Demystifying RF Signals with Ty Purcell !!!

Abstract: The expansion of wireless technologies has introduced a diverse range of hardware, protocols, and radio frequencies. When a large mix of acronyms and names like LoRa, BTLE, ZigBee, RFID and Wi-Fi are thrown-in, one can easily get confused and overwhelmed.
This presentation offers a comprehensive introduction to the RF spectrum for those new to wireless security that will also provide value for experienced practitioners. By taking a broad, big-picture approach, we’ll begin by exploring the electromagnetic spectrum, covering familiar technologies and concepts like infrared, visible light, and x-rays, before narrowing our focus to the portion dedicated to radio frequencies. Key concepts such as wavelength, frequency, and modulation will be explained along the way.
We’ll then delve into the specific wireless frequencies and protocols security professionals are likely to encounter, providing practical examples and tools for detecting, analyzing, and testing these devices and signals.
