In Ross Flynn’s continuing series on exploring Wi-Fi, it’s time to get a little geeky on signals. A signal is simply any information carried on a wave, whether that wave is a RFID, Bluetooth, or, of course, Wi-Fi. This UC is meant to break radio frequency communications down to their most rudimentary components. You will gain a basic understanding of radio frequency wave composition, how devices use the waves to communicate, and tools we can use to interact with them.
To play around more with those signals and the hardware mentioned in this UC, jump into “UC – Aircrack-ng“. For the basics of Wi-Fi with a brief history, frequencies, protocols and encryption methods, check out “UC – Wi-Fi Basics“.

What’s an Upskill Challenge (UC)?
A UC is a CTF-style, bite-sized lesson from the JHT Team, our courseware developers as well as “friends” of JHT. They are meant to be short and to the point. UCs focus on a single tool or concept and are helpful in quickly providing useful skills that might be prerequisites for other types of educational content on the platform.
A UC should be 10 – 30 minutes of student time and have no VMs. There are quizzes to make sure that the content is understood.
Prerequisites for “UC – Signals”
UCs assume no knowledge at all! They’re meant to be completely self-contained, so all of the answers are in the lesson. No outside research is required.
