Abstract

Distributed antenna systems (DAS) represent a suitable method for extending multiple-operator radio coverage into indoor premises, tunnels, etc. With the advent of 4G (and beyond) mobile communications systems and of multiple input-multiple output (MIMO) transmission techniques, a common problem for wireless operators is how to upgrade existing DAS systems to the MIMO technology in a cost-effective way. In this paper novel indoor solutions based on the combination of DAS and MIMO transmission techniques (Interleaved-MIMO DAS solutions) are proposed, and their performance is investigated in realistic cases with the aid of measurements, ray tracing simulations, and LTE link-level simulations.
