Preliminar propagation and MIMO experiments in train tunnels at 5.8GHz

Abstract

In this paper, a complete set-up to subway radio propagation measurement at L and C Band is presented. This set-up has been tested at a real subway tunnel with a special structural characteristics allowing propagation path loss measurements and MIMO analysis in order to study the best system configuration working in subway environments. Therefore, the next step is to present a new measurement camping where a complete characterisation of the diversity possibilities inside a straight and curved tunnel will be provided. This new campaign will take place at the L9 Barcelona Metro Network new facilities.
