1.1 General
This International Standard establishes an AEI system based on radio frequency technologies. This system
is intended for general application in RTTT/TICS. It allows the transfer of the identification codes and further
information about equipment and vehicles used in intermodal transport into such RTTT/TICS and information
systems related to intermodal transport processes. Within the intermodal context of the RTTT/TICS Sector, AEI
systems have the specific objective of achieving an unambiguous identification of an ITU or related equipment
or vehicle or item used in intermodal transport, and to make that identification automatically. Vehicles will be
considered and handled under Intermodal aspects as "Intermodal Equipment". Therefore, a differentiation
between AEI and AVI systems for the purpose of this standard is not required.

1.2 Aim
The aim of this International Standard is to define, describe and specify the System Parameters related to an
intermodal AEI system to provide an enabling Standard, which, while allowing the system specifier to determine
the performance levels and operating conditions, provides a framework for interoperability. Therefore this
International Standard specifies
a) parameters and requirements of the identification system itself,
b) performance criteria necessary to ensure consistent and reliable operation of AEI systems within
international transport processing,
c) requirements of the performance and the position of the electronic devices (tag) when installed on
intermodal equipment, and
d) requirements for the installation of readers, and performance data related to these components.
These parameters of an AEI system shall be identical, compatible or interoperable world-wide in respect of systems
complying to this Standard. Yet it is recognized that, at the implementation level, there may be requirements for
regional or operational differences in the performance levels achieved against these parameters.
