Abstract:
The scarcity of available spectrum bands has prompted the exploration and analysis of strategies for sharing spectrum with existing users. The US is considering several bands as part of its National Spectrum Strategy. In this paper, we consider sharing spectrum with the Broadcast Auxiliary Service (BAS) in the 6, 7 and 12 GHz bands. We develop simple models to examine the impact of interference in these bands to BAS-like operations. Our findings contribute to understanding the feasibility of various spectrum sharing regimes, such as, property rights easement, spectrum commons and spectrum anarchy. The key technical result of this study is that while new spectrum uses in the 6, 7, and 12 GHz bands can cause significant interference, this can be managed effectively through mitigation strategies such as dynamic exclusion zones, lower EIRP levels for indoor use, and advanced detection methods.
