Sharing by denial of service and allocating spectrum in the interest of anti-competitive industries doesn’t make the US more safe and secure. But improving technology, revising policy to promote innovation, and setting high but realistic goals does. The brightest lights in DoD have illuminated the path to success. Reducing DoD’s appetite for dedicated spectrum is step one.
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.
Spectrum policy needs to be guided by the realities of network engineering rather than the desires of network incumbents to protect legacy business models from competition from wireless upstarts. Spectrum policy need not be a team sport.
Many government systems can be replaced by modern upgrades with zero incremental spectrum footprint above the commercial and private systems on which the highly productive civilian sector depends. Look at FirstNet.
Transferring spectrum from old to new users have proven to be much speedier and easier than imagined by PCAST and similar plans of 10 – 15 years ago. Getting governments and government agencies to cooperate is the harder problem.
