The essential input to the exploitation of mobile broadband known as radio spectrum is a scarce resource, whose … allocation and eventual assignment by telecommunications regulator and spectrum authorities across the world is of outmost … importance. The most popular approach to spectrum assignment is to run an auction where frequency bands get assigned over a …

While the international radio regulations (RR) do not prevent opportunistic access, the application of these regulations largely does not encourage such a concept. This is due to the existence of different elements of restriction within these regulations including the absence of a quantified...

This paper aims to provide reliable estimates for the COVID-19 contact rate of a Susceptible-Infected-Recovered (SIR) model, From observable data on confirmed, recovered, and deceased cases, a noisy measurement for the contact rate can be constructed, To filter out measurement errors and...
