KEY USE CASE

Drive testing for QoE optimization

To maintain customer satisfaction, quality of experience (QoE) of end-to-end-services, such as for voice, data, video, and messaging, must be regularly verified. Diversity Optimizer can be used to measure a comprehensive range of QoE key performance indicators (KPIs), which deliver information to initiate optimization tasks. Multiple network technologies can be tested in parallel, depending on the connected devices. With SwissQual’s flexible interface NQView, either standard or fully customized monitors can be used. In addition, also audio alarms and information pop-up messages are available to ensure nothing important will be missed during a measurement.

Fully automated, precise and comprehensive radio frequency measurements can be collected simultaneously, thanks to a connected RF scanner. Using indoor mapping functionalities, Diversity Optimizer can also be used for indoor optimization measurements and for troubleshooting tasks. For optimal portability and carry weight, the connected smartphone can be detached from the Optimizer and used as a standalone QualiPoc handheld tool.
