Last week, the FCC published a Notice of Inquiry (NOI) to investigate the possibility of using frequencies above 24GHz for cellular wireless systems -- specifically, for next-gen mobile data standards such as 5G. Given how we've essentially run out of spectrum in the cellular sweet spot, and how Europe and Asia have already started on their own 5G inquiries, it's high time for the FCC to dig into the possibility of super-fast cellular networks that are as capable as standard wireline broadband.
