Broadband connectivity pervades everyday life but is not routinely available during travel. There are significant economic and quality-of-life benefits available if broadband connectivity can be extended to UK road and rail passengers while travelling. Connectivity for rail passengers has received particular attention from the UK Government. Although mandatory for future rail franchisees to address connectivity, they cannot do so alone because there is no complete, existing solution that can be purchased off the shelf. While parts of the problem are solved, or solvable, there remains the presently unsolved problem of how to link the fixed telecom network to the vehicle access network. An attractive approach is line-of-sight radio links in the millimetre-wave band, with the added improvement of exploiting spatial modes to increase the total amount of data that can be sent on a given link per unit of time, which is the topic of this paper. Spatial modes enable the simultaneous re-use of the same frequency bands in the same line-of-sight link for independent data channels, or in other words, they enhance the spectral efficiency. In addition to railway infrastructure, similar benefits could accrue to motorway users, aircraft passengers while taxiing, ships in port, and complex sensor/actuator networks.
