Agilent Technologies Inc. has announced that the Agilent PXT wireless communications test set is now available for testing voice quality on Voice-over-LTE (VoLTE) 4G phones with the Brüel & Kjær PULSE Audio Analyzer and Head and Torso Simulator (HATS).

Transporting voice over a packet-based LTE cellular infrastructure poses challenges that make voice-quality testing essential. The Agilent and Brüel & Kjær solution combines standards-based test methods with real-world base station emulation, RF test and functional test to ensure that VoLTE phones will meet user's expectations.

"We are delighted that Brüel & Kjær chose to integrate the Agilent PXT wireless communications test set with their PULSE Audio Analyzer and HATS system," said Andy Botka, vice president and general manager of Agilent's Microwave and Communications Division. "The Agilent and Brüel & Kjær solution will enable operators and LTE smartphone developers to make breakthrough VoLTE audio quality measurements."

The Brüel & Kjær PULSE Audio Analyzer and HATS system support testing based on commonly used international standards such as ITU-T P.862 PESQ, 3GPP2 and 3GPP audio test specifications.

The Agilent PXT wireless communication test set represents a significant breakthrough in testing LTE user equipment. It incorporates flexible base station/network emulation, RF parametric and functional tests into one integrated unit and extends Agilent's LTE test solutions for development and verification. Used with Agilent's E6966A IMS-SIP Network Emulator Software, the PXT enables VoLTE phones to make end-to-end voice and video calls using a wide range of industry standard codecs.
