Explore the fundamentals of radio frequency technology in this 43-minute conference talk from DEF CON 33's RF Village. Begin with the basic principles of radio and electromagnetic waves, then progress through essential components including antennas and filters. Delve into advanced concepts such as Shannon and Nyquist theories as they apply to modulation techniques, channel capacity calculations, and software-defined radio (SDR) architecture. Learn how electromagnetic signals function and understand the critical components that make up RF communication links from transmission to reception.
