Functional requirements of radio controlled traction and braking

Report describing functional requirements of the radio communication. An important requirement is to specify a maximum number of seconds allowed for disrupted communication. This time may be linked to the train speed at disruption and to the planned traction and braking actions. The content of this deliverable is general, and only some important requirements are mentioned. The reason behind that is the necessity to discuss and agree with the members of the correspondent CFM project FFL4ES2R-CFM-IP5-03-2015 on the functional requirements of the radio, as they have to be compatible with the future operations of the trains (CFM will run the demonstration in the FFL4ES2R-CFM-IP5-03-2015 project). It is needed to define the operational modes and train configurations, safety codes, band widths, interface between the loco control and the radio, etc. The radio system will be defined according to the defined modes and architecture with the loco. And the detail of this will be known in a work cooperation with the FFL4E S2R-CFM-IP5-03-2015 project. In the project proposal, Table 9 List of OC-CFM interaction meetings and inputs indicates at its first item agenda “Definition of radio requirements”, as it is essential for the development of the task and the detailed deliverable definition. This will be done at the very beginning, and at month 4, according to the planning, this shall be agreed, which will allow a detail Deliverable Development Plan for D3.1.
