Abstract
The creation of secondary spectrum markets emerged as a means to enable flexible spectrum- use mechanisms and abandon a rigid spectrum allocation and assignment approach, which resulted in severe inefficiencies in the use of this resource. At the core of the deployment of spectrum markets lie the definition of electromagnetic spectrum as a tradable commodity, the reallocation of spectrum rights, the creation of incentives for resource owners to lease or transfer their spectrum holdings and the appropriate regulatory framework to support and enforce market transactions. It follows that the viability of spectrum markets depends on technical, economic and regulatory frameworks to render this approach a meaningful alternative for spectrum allocation and assignment.
In this research work, we explore the conditions associated with spectrum markets viability. For this purpose, we utilize Agent-based Modeling in order to study markets under different commodity definitions as well as network configurations. These configurations are gathered in three research stages, which start with the analysis of markets as stand-alone institutions where electromagnetic frequencies, without any associated infrastructure (i.e., “naked” spectrum), are traded. This allows us to explore the degree in which the limitations in spectrum fungibility impact the trading process and outcome.
In the second stage, we focus on refining the tradable commodity in such a way that allows to circumvent the physical limitations of spectrum. To this end, we rely on technologies such as LTE-Advanced and virtualization in order to define a fungible, virtualized spectrum commodity and explore the benefits that this provides for market deployment.
The final stage aims at extending the range of applicability of virtualized commodities and providing opportunities that could address current spectrum service and connectivity requirements. Hence, we explore markets as part of more complex network arrangements, where we rely on middleman theory, matching markets and simple auctions in order to enable resource trading. This requires the analysis of multiple factors that impact market design from the definition of tradable commodities to the characterization of the role and objectives of market participants. These factors stem from relevant technical, economics and regulatory frameworks, which we explore to determine whether our spectrum markets proposal can be considered as a viable and applicable solution.
