The quest for “principles evident in the operation of actual high-demand, high-performance, and high-efficiency wireless networks and in the trajectory of near-term spectrum research and development” continues.
US broadband is nothing to sneer at, as all of us who have taken the time to study it in depth are happy to say. Alternative fact reports targeted at naive journalists have the potential to do serious harm, so I would encourage anyone who finds OTI’s United States of Broadband remotely credible to dig a little deeper before firing off clickbait headlines. You might be a victim of fake news.
Applications that can’t be supported by LTE and its progeny probably can be supported by a small number of alternative technologies that have commercial applications. So sharing by contract should be the default mode.
You can count on rural networks being built out of a variety of wireless technologies in present and near future. As needs for capacity increase, signal processing systems that enable more efficient sharing will keep the rural folks ahead of the tsunami.
