In plain words

TS 38.521-1 specifies measurement procedures for conformance testing of user equipment (UE) RF characteristics in frequency Range 1 as part of 5G-NR. Its tests apply only to mobiles intended to support the relevant functionality, and its requirements appear in separate clauses only when corresponding parameters deviate. It states: "Conformance to the TS 38.101-1 [2] is demonstrated by fulfilling the test requirements specified in the present document."

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
