Modern railway projects all include a requirement for radio network design for both safety of life voice communications and track to train signalling. Radio design principles for rail are the same as those for public/private radio network design, but there are particular requirements for system reliability which must be derived with regard to the overall signalling system design specifications. The specific nature of the radio environment around train borne antennas means that the effects of fading, blocking and inter-modulation can have severe effects on the performance of the radio link. This means that there important factors individual to railway projects that need to be taken into account in order to build a reliable and maintainable trackside radio system at the lowest possible cost.
B Consulting has developed specialised skills in this market, and through the recently formed Rail Industry Radio™ partnership can access specialised and experienced associates with particular expertise of working internationally in the railway industry. Our particular fields of expertise are
- High reliability RF design – no single point of failure in radio and transmission above ground or in tunnels
- Interference mitigated GSM-R designs
- Design, modelling and interference prediction for wideband railway signalling systems operating above 2GHz
