Abstract:

The radio spectrum refers to the range of frequencies suitable for wireless communications. Until recently, spectrum regulatory bodies have always allocated spectrum bands exclusively to certain service providers whose users are referred to as primary or licensed users. Such static spectrum allocation mitigates interference to essential services, yet it creates underutilization of the allocated spectrum. On the other hand, the past decades have seen an explosion in the number of bits transmitted over the air and the existing radio spectrum for data transmission is reaching its capacity. A natural approach to alleviate the artificial scarcity of spectrum due to static allocation is to allow opportunistic use of temporarily idle channels by unlicensed or secondary users to increase the throughput of already allocated spectrum. This talk focuses on the operational decisions on such shared networks.
