Organization: ETSI
Publication Date: 1 April 2007
Status: inactive
Page Count: 39
scope:

The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequency spectrum. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable.

The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz (table 1 refers) using analogue, digital and hybrid (using both analogue and digital) modulation. The present document does not apply to radio microphones or in ear monitoring equipment employing Time Division Multiple Access (TDMA), modulation.

Additional standards or specifications may be required for equipment intended to interface to the Public Switched Telephone Network (PSTN). This facility may be subjected to regulatory conditions.

The present document may be used by manufacturers for testing of the equipment. The equipment tested should be representative of the performance of the corresponding production models.

The maximum power recommended for equipment covered by the present document is 250 mW (erp below 1 GHz and eirp above 1 GHz). Equipment above 250 mW should be tested to EN 300 454-1 [5].

Electromagnetic Compatibility (EMC) requirements are covered by EN 301 489-9 [9].

National regulations on maximum power output will apply. The types of equipment covered by the present document are as follows:

• professional hand held radio microphones;

• professional body worn radio microphones;

• in ear monitoring systems;

• consumer radio microphones;

• tour guide systems; and

• aids for the handicapped (assistive technology).
