Physical resource sharing between wireless operators and service providers is necessary in order to support efficient, competitive, and innovative wireless communication markets. By sharing resources, such as spectrum or infrastructure, which are usually exclusively allocated interference is created on the physical layer. Therefore, the economic gains,(More)
—In this paper, we focus on next-generation cellular networks and discuss physical resources sharing among the operators. This implies cooperative usage of the available radio frequencies and also infrastructure sharing. In particular, we analyze the spectrum sharing gain achievable at different time scales and the main factors impacting on it. Then, we(More)
The paper describes the potential network efficiency gain for network operators by infrastructure and network sharing, which considers both infrastructure and spectrum sharing between wireless cellular network operators. The results and conclusions encourage to consider the inter-operator resources sharing scenarios and techniques as potential solutions for(More)
