In plain words

BER means Bit Error Ratio, as defined in 3GPP TR 21.905. In TS 25.141 and TS 25.142, the definition says "The BER is the overall BER independent of frame erasures or when erased frames are not defined.". TS 51.021 uses BER in a conformance requirement for static propagation conditions, with BER ≤ 10-4 for input levels up to -40 dBm.

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.
