Hi,
This specification has been developed within UIC Project EIRENE. It specifies a digital radio standard for the European railways applicable worldwide. It forms part of the Technical Specification for Interoperability.
The EIRENE Functional Requirements Specification defines the requirements of a radio system satisfying the mobile communications needs of the European railways applicable worldwide. It encompasses ground-train voice and data communications, together with the ground-based mobile communications needs of trackside workers, station and depot staff and railway administrative and managerial personnel.
The EIRENE Functional Requirements Specification defines a set of requirements which a railway radio system should comply with, in order to facilitate international interoperability between national railways and manufacturing economies of scale. This specification therefore defines the functional requirements, to ensure that core railway functionality is provided.
The document is "SoC_EIRENE FRS.xlsx", from a certification institute of Europe.
I wonder in +55 deg, humanbeings can't stand with ONE hour, but the test case requires EIGHT hours, some nonsense, especially for mobile phone.
So DC supply is possible just to verify the circuit performance, not including battery, that is also common in mobile test.
Do you have comments?
Best,
Tony Liu
