  VoLTE Testing with MFE VIII.1 - New front end offers new possibilities for VoLTE test setups
HEAD Press Release Herzogenrath, October 31, 2012
VoLTE Testing with MFE VIII.1:
New front end offers new possibilities for VoLTE test setups
HEAD acoustics has just announced its new voice quality test solution for Voice-over-LTE (VoLTE), which integrates HEAD acoustics’ widely established ACQUA analysis system, the HMS II.3 artificial head and the MFE VI.1 measurement front end as well as the new MFE VIII.1 reference gateway

The system setup also offers various possibilities of incorporating an air interface. Complete setups including LTE tester and IMS server have already been successfully tested (cf. picture below).
Although the new test system also supports the earlier MFE VIII front end model, the new MFE VIII.1 reference gateway represents an important step forward in test technology for both narrowband and wideband telecommunication devices in IP and LTE networks.
The new front end offers a number of advanced features that allow a greater freedom of configuration. Additional VoIP codecs are offered, including AMR/AMR-WB and ‘Speex’, while further codecs are implementable as software plug-ins at a later date. Clock adjustment to avoid delay drifts between VoLTE DUT and setup which can cause misinterpretation of test results is on board as standard.
The new voice quality test system for VoLTE combines HEAD acoustics’ innovation skills with established over-the-air RF test capabilities offered by various partners and consolidates HEAD acoustics leading position in the market.
