E-model

Calculation tools

Welcome to the implementation of the E-model as defined in the following ITU-T Recommendations

• Narrowband E-model: Recommendation ITU-T G.107 (06/2015)
• Wideband E-model: Recommendation ITU-T G.107.1 (06/2019) and its Corrigendum 1 (01/2020)
• Fullband E-model: Recommendation ITU-T G.107.2 (06/2019)

The original version of the calculation tools was kindly offered by x-fabric.com in 2003. This page was last updated in September 2020.

It gives you the opportunity to make online E-model calculations and to obtain the R value as the result.

This implementation is easy to use and tooltips provide useful hints. Users are encouraged to read the ITU-T Recommendations mentioned above.
