MOS measurement

Multi-Port Hub for Voice MOS testing up to 4 UEs

XCAL-MPm4 is the smallest and yet most flexible of Accuver's network benchmarking solution. The XCAL-MPm4 scales four ports (supporting four simultaneous phones). Each port comes with its own individual sound control, allowing independent standard-based voice quality (MOS) testing that can be used for both mobile-to-mobile or mobile-to-landline test scenarios. The unique feature of this tool is that any phone that supports Bluetooth, can be used for voice quality analysis - proving that high quality, scalable and robust network benchmarking tools need not cost the earth.

  • Use XCAL-MPm4 to

    • Perform network benchmarking tests using up to four mobile phones
