GAO Report: FCC Should Track Growth to Ensure Sufficient Spectrum Remains Available

The stakeholders the US Government Accountability Office spoke with identified two primary spectrum-related challenges for the internet of things (IoT)—the availability of spectrum and managing interference. Although not considered an immediate concern, Federal Communications Commission (FCC) staff and some stakeholders noted that rapid increases in IoT devices that use large amounts of spectrum—called high-bandwidth devices—could quickly overwhelm networks, as happened with smart phones. Stakeholders and FCC staff also indicated that managing interference is becoming more challenging as the number of IoT and other wireless devices grows, particularly in bands that do not require a spectrum license. The figure below illustrates the uses of radio frequency spectrum, including unlicensed use.

FCC should track the growth in (1) high-bandwidth IoT devices and (2) IoT devices that rely on unlicensed spectrum. FCC did not believe these actions are necessary but noted that it would ask its TAC to periodically review and report on IoT’s growth. GAO continues to believe the recommendations are valid.
