  Abstract: Next generation mobile networks will have to rely ever more heavily on network sharing. Herein we apply stochastic geometry to assess the fundamental trade-offs between spectrum and radio access infrastructure sharing. We find that spatial dependency between networks of multiple mobile operators has a significant impact on the efficiency of resource sharing. Furthermore, we observe that while spectrum sharing alone provides an increase in the data rate at the expense of coverage, infrastructure sharing results in improved coverage. When the two sharing types are combined, we observe significant increase in the average user data rate and minor improvements to the network coverage as compared to the non-sharing scenario. Yet, as we show, even a simple mechanism of coordination in spectrum sharing allows operators to reduce the impact of this trade-off and improve their coverage without hampering the user data rates. Additionally, we observe that the way in which spectrum is being shared makes a difference to both the coverage and data rate performance. In particular, when coverage is the main concern, it is more beneficial for operators to allow for their transmitters to dynamically select among the pooled spectrum bands, rather than simply bond the available channels.
