Recent initiatives allow cellular providers to offer spot service of their licensed spectrum, paving the way to dynamic secondary spectrum markets. This paper characterizes market outcomes when multiple providers are drawn into competition for secondary demand. We study a game-theoretic model in which each provider aims to enhance its revenue by(More)
We introduce an economic model for private commons that consists of network providers serving a fixed primary demand and making strategic pricing decisions to improve their revenues by providing service to a secondary demand. For general forms of secondary demand, we establish the existence and uniqueness of two critical prices for each provider: the(More)
This paper characterizes the outcomes of secondary spectrum markets when multiple providers compete for secondary demand. We study a competition model in which each provider aims to enhance its revenue by opportunistically serving a price-dependent secondary demand, while also serving dedicated primary demand. We consider two methodologies for sharing(More)
Motivated by recent regulatory evolutions that pave the way to secondary spectrum markets, we investigate profit maximization in a loss network that accommodates calls of two classes of users: 1) primary users (PUs) and 2) secondary users (SUs). PUs have preemptive priority over SUs, i.e., when a PU arrives to the system and finds all channels busy, it(More)
We introduce a private commons model that consists of network providers who serve a fixed primary demand and strategically price to improve their revenues from an additional secondary demand. For <i>general</i> forms of secondary demand, we establish the existence and uniqueness of two characteristic prices: the break-even price and the market sharing(More)
A recent policy ruling by the Federal Communications Commission (FCC) set aside a fixed amount of cleared spectrum for smaller network providers. Thanks to this ruling, smaller providers can improve their quality of service using carrier aggregation. In this paper, we determine the optimal (minimum) level of carrier aggregation that a smaller provider needs(More)
