Keysight Technologies' Application Note Offers Test Solution for VoLTE Phones



Keysight has released a new application note, Testing Voice over LTE (VoLTE) Phones. The application note explains a test solution for use by LTE mobile phone developers, test engineers and test lab personnel. The test solution incorporates Keysight's E6966B IMS-SIP network emulator software and E7515A UXM wireless test set.

Detailed instructions highlight the ease of confirming VoLTE functional performance with end-to-end voice calls, voice echo, video calls, SMS, IMS registration and emergency calls, as well as supplementary services such as conference call and call waiting.

The note also details how, with the addition of a Keysight U8903B performance audio analyzer, the audio interface enables in-depth PESQ and POLQA voice quality testing.
