Usecase Drive Testing Voice services performance

Real-world Voice services performance
Assess end-user voice and service experience across a geographic area.

Drive testing for voice quality provides real-world insights into how mobile networks perform under varied geographic and mobility conditions, capturing issues like dropped calls, poor handovers, and low signal areas. It complements lab testing by validating user experience, supporting network optimization, and ensuring regulatory or competitive performance standards are met.

Opale Drive Test Solution

MultiDSLA drive test systems with GPS provide a full range of performance measurements, including:

• Speech quality score (POLQA, PESQ),
• One-way delay,
• Speech level,
• Noise level,
• GPS location and time,
• Uplink/downlink analysis.

Drive Testing Applications include:

• Handset comparison, e.g. with ‘reference’ handset – any number of handsets may be used simultaneously, with separate reporting for each one.
• Competitive network comparison – for any number of networks.  Using identical handsets will give a direct comparison of network coverage and general performance.
• Detailed network performance analysis – typically within a single network and with a reference handset.  The objective may be to study network behaviour in particular circumstances, to investigate customer complaints or to confirm performance following a network upgrade or maintenance work.
• Fixed line to mobile.
• Mobile to mobile.
