Abstract

Transport communications systems face challenges relating to the number, density and velocity of passengers. In the rail environment, it would be advantageous to be able to provide broadband-like data connectivity to all passengers. Due to the limited number of connection points into trackside fibre-optic cables (ca. one per 5 km), and the limited spacing possible between trackside-to-train links (ca. 100m due to fog), novel solutions for track-side communications backbones are needed. We estimate the total capacity as being in the order of 40 Gbit/s, which requires the investigation of novel means of providing spectral efficiency. Spatial modes offer significant benefits, but also bring challenges such as requiring large antenna apertures, which may be tackled by using partial aperture antenna approaches or by employing lenses.
