"An Economic Perspective on Spectrum and Infrastructure Sharing in Millimeter Wave Cellular Networks"

Abstract: With the increasing interest in the use of millimeter wave bands for 5G cellular systems comes renewed interest in resource sharing. Properties of millimeter wave bands, such as massive bandwidth, highly directional antennas, high penetration loss, and susceptibility to shadowing, suggest technical advantages and potential cost savings due to spectrum and infrastructure sharing. However, resource sharing can also affect market dynamics of price and demand, potentially reducing service provider profit or consumer surplus. In our work, detailed simulations of millimeter wave and microwave networks are connected to economic models of markets for network goods, where consumers' utility depends on the size of the network. The results suggest that in a vertically differentiated duopoly market, resource sharing is less often profitable for millimeter wave service providers compared to microwave cellular service providers, and does not necessarily increase consumer surplus. We also consider resource sharing in the context of barriers to market entry, and find that in millimeter wave networks, a deployment of open-association small cells encourages market entry by making it easier for networks to reach critical mass, and that unlicensed spectrum does not have a similarly encouraging effect.
