Breakthrough 4G Phone Quality System from Brüel & Kjær and Agilent Technologies

Press Release:
  Jun 8, 2012 — A new system for testing the next generation of 4G phones that use Voice-over-LTE technology has been developed by Agilent Technologies and Brüel & Kjær.

“The Agilent and Brüel & Kjær solution enables operators and smartphone developers to make highly reliable and integrated Voice-over-LTE audio quality measurements,” said Andy Botka, Vice President and General Manager of Agilent's Microwave and Communications Division.

The system uses Brüel & Kjær’s PULSE analyser platform coupled with a Brüel & Kjær Head and Torso Simulator (HATS), and interfaces it with Agilent’s PXT wireless communications test set.

“The performance of our measurement systems relies heavily on the capability of the test equipment we support, so we are pleased to announce that, in working closely with Agilent, we now offer this complete Voice-over-LTE audio quality test solution to our customers,” said Lars B. Nielsen, Brüel & Kjær’s Telecom & Audio Market Manager.

Transporting voice over a packet-based LTE cellular infrastructure poses challenges that make voice-quality testing essential. The Agilent and Bruel & Kjaer solution combines standards-based test methods with real-world base station emulation, RF testing and functional testing into one unit, to ensure that the next generation of Voice-over-LTE phones meet user's expectations.

Brüel & Kjær’s PULSE analyser platform and HATS system support testing based on commonly used international standards such as ITU-T P.862 PESQ, 3GPP2 and 3GPP audio test specifications.
