This whitepaper discusses optimal ways to test the quality of voice service in broadband wireless networks (e.g. 3G and 4G/LTE) using PESQ and POLQA algorithms. With advances in the field of intrusive speech quality measurement brought in by the POLQA algorithm, a system and device neutral assessment of a wide variety of voice call applications, including not only cellular technologies but also data and stream based technologies, is now possible.
