Internet of Things: FCC Should Track Growth to Ensure Sufficient Spectrum Remains Available, Report to Congressional Requesters [open pdf - 2MB]
"IoT [Internet of Things] generally refers to devices (or 'things'), such as vehicles and appliances, that use a network to communicate and share data with each other. The increasing popularity of wireless IoT devices that use spectrum has created questions about spectrum needs. GAO [Government Accountability Office] was asked to examine issues related to spectrum and IoT. This report discusses, among other things, (1) spectrum challenges related to IoT, (2) how the federal government plans for IoT's spectrum needs, and (3) how selected leading countries prepare for IoT's spectrum needs."
