  New HEAD acoustics Revision of 3GPP Specifications TS 26.131/32 for LTE
HEAD Press Release Herzogenrath (Germany), December 16, 2014
New HEAD acoustics Revision of 3GPP Specifications TS 26.131/32 for LTE
The 3GPP specifications TS 26.131 and TS 26.132 have again undergone a major revision that led to the recent publication of Release 12. HEAD acoustics is the first test solution provider to have implemented Release 12.
Experts agree that Release 12 of the 3GPP specifications constitutes an important step forward in the global standardization of wideband-capable telecommunication devices including LTE terminals. Numerous measurements have been modified or added in order to establish a close-to-reality and forward-looking standard:
LTE speech quality measurements have been introduced with the latest version of Release 12 and have been implemented in the latest revision of the measurement standard TS26131-32 for the HEAD acoustics communication analysis system ACQUA.
VoLTE specific measurements require MFE IX (or another IP network simulator). The network impairments (TCN file) according to TS 26.131/32 are included in the delivery of the ACQUA measurement standard and can easily be uploaded to MFE IX.
Configuration methods for different LTE radio testers are now available.
The use of MFE VIII.1 as reference gateway offers considerable advantages, particular with regard to delay and jitter handling.
Despite the added features, the price of the measurement standard has not been changed.
The new revision of the measurement standard TS 26131-32 is available for HEAD acoustics customers with valid software maintenance agreement (SMA) by download as of now. It requires the new ACQUA version 3.2.200 with ACOPT 21 (3QUEST) and the corresponding standard license as well as further components. An updated data sheet for TS26131-32 is available from the HEAD acoustics download center at
