In this paper, the authors study how key dynamic spectrum access operating parameters impact radios' ability to fairly access wireless spectrum. Additionally they investigate intentional spectrum access policies that allow priority radios (e.g. public safety or defense) to preempt access to the spectrum by lower priority (e.g. commercial) radio networks. For fairness, they demonstrate that small differences in key radio parameters, such as scanning time, sensing time, frame time, and rendezvous time, can cause dramatic inequities in access to spectrum. Radios that take longer to rendezvous will have fewer chances to grab available spectrum in a crowded environment, as compared to radios with shorter rendezvous times.
