The NFPA and IEEE recommend a ground resistance value of 5 ohms or less while the NEC has stated to “Make sure that system impedance to ground is less than 5 ohms specified in NEC 50. In facilities with sensitive equipment it should be 5ohms or less”. . Figure numbers of IEC TR 62669 are extracted from a preliminary draft DTR version and may change in the final version expected to be published in 2025. in-situ RF exposure assessment – measurement of in-situ RF exposure levels in the vicinity of a BS installation after the product has been taken. . The latest European Standard to asess Radio Frequency RF field strength, power density and specific absorption rate (SAR) levels in the vicinity of base stations (BS), which are also called products or equipment under test (EUT). This European standard adopts in Europe the newly released IEC. . This paper was developed by the ITU Office for Europe within the framework of the ITU Regional Initiative for Europe on broadband infrastructure, broadcasting and spectrum management. Transient voltage introduced. . The technical conditions for Mobile/Fixed Communications Networks (MFCN) operating in the band 3400-3800 MHz are specified in ECC Decision (11)06 [1] and the corresponding EC Decision 2019/235 [2]. Base station additional baseline power limits below 3400 MHz are stated in Table 5 of the ECC. . The present document may be made available in electronic versions and/or in print.
