Question 18/V - Radiated radio frequency interference and telecommunications equipment and systems (New Question) The purpose of this Question is to establish Recommendation(s) on the subject of radiated radio frequency interference for telecommunications equipment. Guidelines on improving the design of telecommunications equipment and systems along with advice on precautionary measures shall be developed. Both emission and immunity aspects are to be studied. The work shall address: i) what parameters should be considered when testing telecommunications equipment to ensure compatibility with other telecommunications systems and national EMC regulations; ii) what measuring procedures should be adopted; iii) the definition of acceptable immunity performance; iv) the failure criteria of equipment when subjected to interference; v) protection methods that may be adopted to improve the performance of telecommunications equipment and systems. Note 1 - In the study of this Question the work of other standards organizations such as IEC (CISPR and other bodies) along with national regulations, as well as of CCIR (Study Group 1) shall be considered to avoid the duplication of work.
