ITU-T K.136 PDF

This Recommendation specifies the general requirements of electromagnetic compatibility (EMC) and test methods for radio telecommunication and associated ancillary equipment. Radio equipment includes, e.g., mobile access network equipment such as base stations, fixed radio links equipment such as microwave relay, fixed-satellite service, radio navigation-satellite services, short-range devices, mobile broadband access devices, mobile-satellite service, and wireless access point devices. Specific product Recommendations, e.g., [b-ITU-T K.114] and [b-ITU-T K.116], take precedence over this Recommendation. EMC test methods for wireline ports can be found in [ITU-T K.137].

The working frequencies of radio equipment could be from 9 kHz to 400 GHz.

This Recommendation describes the common testing operational conditions and performance criteria.

The environmental classification locations used in this Recommendation refer to [ITU-T K.34].

This Recommendation defines the specific immunity testing levels and performance criteria to be applied to radio network telecommunication equipment in the following environments:

– telecommunication centres; see clauses 6.1.1 and 6.1.2 of [ITU-T K.34];

– outdoor locations (e.g., streets, parking roofs, towers, poles): see clause 6.2 of [ITU-T K.34];

– customer premises (residential, commercial or light industrial environment): see clause 6.3 of [ITU-T K.34].

The immunity requirements of this Recommendation have been selected to ensure an adequate level of immunity. Extreme cases of disturbances with low probability of occurrence are not considered. In special cases, situations may arise where the levels of disturbance may exceed the immunity test levels defined in this Recommendation. In these conditions, special mitigation measures or protection may have to be implemented.

The emission requirements of this Recommendation refer to the classification provided in [CISPR 32].
