scope:

This European Telecommunication Standard (ETS) covers the assessment of the 2,4 GHz wideband transmission systems and HIgh PErformance Radio Local Area Network (HIPERLAN) equipment in respect of ElectroMagnetic Compatibility (EMC).

This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimum performance criteria for wideband data communication systems, such as plug-in radio devices, handportable equipment, mobile and fixed stations, as specified in ETS 300 328 [1], HIPERLAN Type 1 as specified in ETS 300 652 [2].

In addition to the technical specifications of this ETS, there may be published in the Official Journal of the European Commission references to other Harmonized EMC Standards that apply to the products covered by this ETS in their own right.

The environmental classification used in this ETS refers to the environment classification used in the generic Standards EN 50081-1 [3], EN 50082-1 [4], except the vehicular environment class which refers to ISO 7637, Parts 1 [5] and 2 [6].

The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at residential, commercial, light industrial and vehicular environment. The levels however, do not cover extreme cases which may occur in any location but with low probability of occurrence.

Technical specifications related to the antenna port and emissions for the enclosure port of the equipment are not included in this ETS. Such specific technical specifications are found in the relevant product standard.

This ETS may not cover those cases where a potential source of interference which is producing individually repeated transient phenomena or a continuous phenomena is permanently present, e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference or the interfered part or both.

Compliance of radio equipment to the requirements of this ETS does not signify compliance to any requirements related to spectrum management or any requirement related to the use of the equipment (licensing requirements).

Compliance to this ETS does not signify compliance to any safety requirements. Any observations of equipment becoming dangerous or unsafe as a result of the application of the tests defined in this ETS shall be recorded in the test report.

This ETS is based on the considerations and guidance given in ETR 238 [15].
