HEAD acoustics provides interoperability with first test solution for 5G VoNR

  • Feasibility with the first 5G test solution on the market
  • Testing communication quality of VoNR-capable devices
  • Application note with detailed information on 5G/4G connection establishment

HEAD acoustics hardware and software solutions have now proven feasibility with the first solution on the market for testing communication quality of 5G (VoNR)-capable devices: The hardware platform labCORE and the measurement and analysis software ACQUA are interoperable with the latest radio communication tester by the US-American company Keysight Technologies, Inc. Combining labCORE, ACQUA and the Keysight E7515B UXM 5G, it is possible to establish a voice call in a 5G as well 4G (VoLTE) network. Manufacturers of 5G-capable telecommunication devices are thus able to test the voice quality of their devices.

5G connection establishment

The device under test registers via 5G/4G network at the IP multimedia subsystem (IMS) server of the Keysight platform. labCORE connects to this platform via wired Ethernet and also registers at its IMS server. Within ACQUA, users can establish a voice call between labCORE and the device under test. “This interoperability is another milestone for our customers in terms of testing and optimizing communication quality of 5G devices. I am more than confident that our solution will be compatible with other platform providers in the near future”, says Christian Schüring, sales manager Telecom at the HEAD acoustics GmbH. The German-based company has published an application note with detailed information on how to establish 5G/4G connection to labCORE via the Keysight radio tester. The document is publically available on the company website:
