Spectrum-sharing with radar often means operating outside “exclusion zones” near the radar. However, it is technically possible for cellular systems to operate close to radar at data rates that are high on average without causing harmful interference simply by adjusting dynamically as the radar rotates. Despite fluctuations in data rate, cellular quality of service is sufficient for the applications that generate the vast majority of Internet traffic. This is an example of how “gray space sharing” can make more efficient use for spectrum; cellular devices operate on a secondary basis in spectrum that is not “unused.” Although technically possible, this form of sharing poses new policy challenges. Particularly in cases where there are multiple entities operating primary systems and multiple entities operating secondary systems in the same spectrum, a new form of governance is needed to prevent, detect, and respond to harmful interference.
