- [Narrator] Use of the internet on the go or when making mobile phone calls is made possible thanks to the invisible electromagnetic waves that mobile phones emit or receive. However, did you know that this electromagnetic frequency range or spectrum is a highly precious resource? In 2008 the U.S. government made a whopping 19 billion dollars through a spectrum auction.
