ETSI TS 126 131 is applicable to any terminal capable of supporting narrowband, wideband, super-wideband or
fullband telephony, either as a stand-alone service or as the telephony component of a multimedia service. The present
document specifies minimum performance requirements for the acoustic characteristics of 3G and LTE terminals when
used to provide narrowband, wideband, super-wideband or fullband telephony.
The set of minimum performance requirements enables a guaranteed level of speech quality while taking possible
physical limits of the terminal design into account. Some performance objectives are also defined, if such design limits
can be overcome. Care must be taken in applying performance objectives in isolation, not to degrade overall end-user
speech quality.
