D4.2 – Requirement specifications for Communication Report

The primary objective of D4.2 is to outline a set of requirements and architectures that reflect the operational and functional behavior of:
1 – The external wireless interfaces of D4.4 Smart Wayside Object Controller (SWOC) Multi Modal Level Crossing (MMLX).
2 – The trackside-trackside and trackside-field devices wireless communications in general.
In addition to specifying requirements, D4.2 parts (documents) also include analysis and investigations of new direct wireless communication trackside to train in the context of SWOC MMLX.

This document also provides sections describing the process used to derive (a) the architecture from the requirements, (b) the requirements from the Use Cases and (c) it also describes how the requirements are managed.
The linked parts (documents) discuss the social-economic benefits targeted by the requirements and architecture specifications. FP6 FutuRe project has accepted the lack of cost baselines from infrastructure managers, thus D4.2 cost reduction proposals may need to be verified in the future. It is highly recommended to read this delivery in conjunction with D4.4. Both deliveries are deeply interconnected and they complement each other. The formal links between D4.2 and D4.4 are presented later in this document in the requirements and documents structure. Specifically, High Level Requirements for Communication interfaces are defined to fit D4.4 context.
