What it is:

POLQA is the global standard for benchmarking voice quality of fixed, mobile and IP based networks. It was standardized by the International Telecommunication Union (ITU-T) as Recommendation P.863 in 2011 and can be applied for voice quality analysis of VoIP, HD Voice, 3G and 4G/VoLTE networks. An advanced POLQA version was adopted in September 2014.

The POLQA standard was developed during 2006-2011 by leading industry experts within ITU-T Study Group 12, from the requirement for a technology upgrade to PESQ (ITU-T Recommendation P.862), its predecessor of 2001, and a competition carried out to define the 3rd generation of perceptual voice quality metrics. POLQA - was derived from the ITU working title "Perceptual Objective Listening Quality Analysis" - offers an advanced level of benchmarking accuracy and adds significant new capabilities for wideband and super-wideband (HD) voice signals, along with support for most recent voice coding and VoIP/VoLTE transmission technologies. POLQA is ideally suited to evaluate, optimize and monitor the voice quality of next-generation networks.

The POLQA perceptual measurement algorithm is a joint development of OPTICOM, SwissQual and TNO, protected by copyrights and patents and available under license from OPTICOM as software for various platforms. The POLQA Coalition has further advanced POLQA by developing a new version V2.4, “POLQA 2015”, which was adopted by ITU-T SG12 in September 2014.

To date, 109 vendors and operators license POLQA/P.863 for their products or for use during development, design and optimization of mobile phones, Smartphones, network components, or services.

Evolution of VQ Testing

Who needs POLQA:

Mobile and NGN operators, Test & Measurement and in particular DTT manufacturers for benchmarks of 3G, 4G/LTE and NGN networks PESQ/P.862.x was originally released in the year 2001. Since then, and as visible in a time line diagram above, certain key technologies like speech codecs and 3G/4G evolution have been introduced. While PESQ has proven to be very robust, POLQA significantly improved benchmark accuracy for 3G, and strong support for testing of today´s technologies such as Unified Communications, Next Gen Networks and 4G/LTE. Besides classical band-limited telephony POLQA supports HD Voice, i.e. 'wideband' and 'super-wideband' telephony up to 48 kHz sampling frequency.

POLQA approved for Voice Quality Characterization of EVS Codec

POLQA, the global standard for benchmarking mobile voice quality can now also be safely applied to characterize EVS coded speech signals. As a result, commercial products running POLQA version 2015 (v2.4) are already validated for EVS support and do need an extra update. OPTICOM and SwissQual’s initiative enabled ITU-T SG12 to add a new Implementer’s Guide (…)

How to buy:

  • POLQA for End-Users (Commercial Use)

    Leading Test & Measurement manufacturers have (or shortly will have) adopted POLQA/P.863 in their products covering a wide scope of applications from lab tools, over production testing, network design and optimization to benchmarking and monitoring.

    In order to find out which is the proper tool set for your application, you may look up our reference list of licensed POLQA vendors.

  • POLQA for Academic/Educational Use

    Academic users who are looking for a download of reference source code on the ITU-T website should consider that Recommendation P.863 is defined by an algorithmic description and pseudo code for some essential parts of it.

    There is no directly compilable source code for POLQA available. In order to support evaluations based on a standard conforming POLQA implementation, OPTICOM – on behalf of the POLQA Coalition

  • POLQA OEM Licensing

    For professional vendors looking to integrate POLQA into their product or system, easy accessibility to POLQA is assured. The parties to the POLQA Coalition have founded a joint P.863 patent pool with OPTICOM as sole licensing agent.

    This means OPTICOM will provide one-stop IPR licensing along with advanced POLQA OEM software tools for various platforms.

Who we are:

The POLQA coalition consists of OPTICOM, SwissQual and TNO, the group of companies who won the competitive standardization process run by the ITU-T, and KPN, who own essential patents on the TNO technology. The candidates submitted for testing by OPTICOM, SwissQual and TNO were the only algorithms that clearly met the criteria in the ITU-T selection phase in June 2010. Thereafter, OPTICOM, SwissQual and TNO have agreed to combine their expertise into a joint and uniform solution. This joint solution was standardized as ITU-T Rec. P.863 (2011). POLQA enabled products are available to end-users in hardware and software from various vendors – see our list of references. OPTICOM acts as the sole one-stop licensing agent for the POLQA technology on behalf of the POLQA Coalition, while SwissQual, TNO and KPN take a more passive role with regard to POLQA licensing.
