DAS Modifications for More Efficient Network Cost in 5G

Demanding goals have already been described concerning the next generation of mobile networks. In order to address these requirements, novel technologies are introduced or new concepts are integrated into conventional ones. In this paper, a modified Distributed Antenna System (DAS) architecture is described and a Sensitivity Analysis (SA) indicates which of the network cost parameters are the most influential ones concerning this model. Several hardware components are replaced with Network Function Virtualization (NFV) techniques, which are introduced, so as to contribute in reducing capital and operational expenses. The model is described mathematically, is compared and contrasted with the conventional model proposed by authors in past research activity. Simulation scenarios help concluding into fundamental results concerning the most dissuasive cost factors e.g. bandwidth, frequency, capacity, coverage, etc.
