The study was undertaken to provide ComReg with an independent view on whether all the GSM-R spectrum band should be awarded for a planned railway communications network deployment in Ireland.  In conjunction with ClearCinCom an assessment was made of the GSM-R network design requirements provided, including the need to support ETCS Level 2 applications, and the associated coverage and traffic requirements proposed for the network and the implications for frequency planning.  This approach allowed a view to be taken on whether the frequency planning and associated spectrum requirements were considered reasonable.
