For several years, the Federal Communications Commission (FCC) has been working to modernize the use of key sections of spectrum airwaves — known as C-band — for commercial deployment. Through a series of auctions, the FCC sold the license rights to C-band airwaves to commercial 5G mobile telecommunications providers, unleashing a massive wave of private investment to enable 5G deployment. But the Federal Aviation Administration (FAA) recently warned that using C-band for 5G could interfere with air safety, reigniting a multiyear battle that many believe FCC engineers have successfully put to rest. What does the FAA’s warning mean for the future of C-band and continued spectrum deployment in the wireless industry?

On this episode, Shane sits down with former FCC Commissioner Mike O’Rielly and Harold Feld of Public Knowledge to discuss why the FAA issued this warning, how legitimate its safety concerns are, and how the C-band auction winners have responded.
