ETSI - TS 126 132
Universal Mobile Telecommunications System (UMTS); LTE; Speech and video telephony terminal acoustic test specification
|Publication Date:||1 August 2016|
The present document 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 test methods to allow the minimum performance requirements for the acoustic characteristics of GSM, 3G and LTE terminals when used to provide narrowband, wideband, super-wideband or fullband telephony to be assessed.
NOTE For 3G and LTE, acoustic requirements are specified in TS 26.131, test methods are specified in TS 26.132. For GSM, most acoustic requirements are specified in TS 43.050, test methods are specified in TS 51.010. These specifications are in many cases harmonized with or even refer to TS 26.131 and TS 26.132. See TS 43.050 and TS 51.010 for details. The reason for including GSM, UMTS and LTE terminals within the scope of the present specification is to avoid, whenever possible, duplication of test method descriptions for terminals supporting multiple access technologies.
