RF 101: Fundamentals of Radio Frequency Technology

Master the fundamentals of radio frequency technology and learn how wireless communications work, from spectrum allocation and signal propagation to identifying security vulnerabilities.

The RF 101 series gives IT security professionals a clear understanding of radio frequency fundamentals and their security implications. It covers the spectrum from 60 MHz to 50 GHz where most wireless communication occurs, FCC spectrum management across licensed and unlicensed bands, hardware-defined versus software-defined radios, modulation methods, multiple access schemes, and RF propagation factors such as line-of-sight, shadowing, path loss, and multipath interference. It also explains how to use the FCC’s public device certification database to identify wireless protocols and vulnerabilities, and examines the emerging threat of dynamic spectrum access technologies like white space radios that can transmit large amounts of data over long distances in the 100–700 MHz range, underscoring the need for security teams to monitor these often-overlooked frequencies for potential data exfiltration.
