The present document, together with EN 301 489-1 , covers the assessment of radio equipment meeting Phase 1, Phase 2, and Phase 2+ GSM and DCS digital cellular mobile and portable radio equipment transmitting and receiving speech and/or data, and operating in digital cellular radio telecommunications systems, and associated ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of radio equipment are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for Phase 1, Phase 2, and Phase 2+ GSM and DCS digital cellular mobile and portable radio equipment, transmitting and receiving speech and/or data, and associated ancillary equipment. Examples of digital cellular mobile and portable radio equipment covered by the present document are given in annex A. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN 301 489-1 , the provisions of the present document take precedence. Base station equipment (BTS and BSS) operating within network infrastructure is outside the scope of the present document. However, the present document does cover mobile and portable equipment that is intended to be operated in a fixed location while connected to the AC mains (see clause 5.5). The environment classification and the emission and immunity requirements used in the present document are as stated in EN 301 489-1 , except for any special conditions included in the present document.
