Abstract

The new requirements for 5G, in terms of latency and bandwidth, demand new technologies such as millimeter-wave small cells, requiring dense deployments to achieve good coverage. Even before the arrival of 5G, small cells were already being deployed to avoid congestion and achieve a good Quality of Service (QoS) in areas with high densities of potential users. These infrastructures require large investments, forcing operators to share them or to use the services of a neutral host, responsible of installation and maintenance. In this paper we present a practical approach for different operators to share a small cell infrastructure, while allowing them to use their respective dedicated frequencies, adjust any parameter, or even deploy any particular radio access technology. This way, each operator can provide a differentiated service that may represent a competitive advantage even on the same physical infrastructure.
