Spectrum and Infrastructure Sharing in mmWave Cellular Networks

Resources that are “open”, such as unlicensed spectrum, a deployment of base stations open to all service providers, or resources that are shared among a coalition of service providers by agreement, may offer greater sharing gains in mmWave bands than at conventional cellular frequencies. However, even when sharing is technically beneficial, it may not be profitable. In this project, we study both the technical and economic implications of resource sharing in millimeter wave cellular networks. Our findings include the following:

  • Without open resources, market entry can be challenging in mmWave networks. “Open” deployments of neutral small cells that serve subscribers of any service provider encourage market entry by making it easier for networks to reach critical mass. Unlicensed spectrum does not have a similarly encouraging effect on market entry.
  • – In a vertically differentiated duopoly market, resource sharing increases revenue less often for millimeter wave service providers than it would for microwave cellular service providers, and does not necessarily increase consumer surplus. Resource sharing is profitable for both service providers in a duopoly mmWave market only when the market is highly segmented and there is little price competition.
