Wireless connectivity needs to be high capacity and reliable for present and future high speed land transportation systems, including rail, road and hyperloop. All such moving platforms transport a substantial number of passengers, creating high data demands in often remote areas. This paper proposes how to re-think the means by which wireless connectivity is implemented to provide wireless services to a dense number of users on a fast moving platform. The proposed concept evolves from orbital angular momentum radio modes for data multiplexing to linear or planar angular momentum instead. In this study, the wireless link is placed underneath the moving platform, a promising low-cost method that potentially could achieve 9Gbps with 15MHz bandwidth and 10dB signal to noise ratio from initial analysis carried out.
