​The Challenge

• Difficulty in measuring real-life and LIVE network performance

• Current measurements with simulators do not reflect the actual user experience

• The existing solution was locked to specific hardware and was too costly and  time-consuming to expand the scope of testing and add new KPIs

​

The Solution

• The viSer Test Automation solution was selected with an Audio MOS add-on package and the following KPIs were measured:

• Call Performance (2G, 3G, VoLTE, VoWiFi) including WhatsApp

• Voice Quality (2G, 3G, VoLTE, VoWiFi) including WhatsApp

• Data Performance (2G, 3G, 4G)

• VoLTE, VoWifi

• Web browsing fluidity

• Network benchmark. Able to compare with competitors MNVOs & MNOs

• Field testing in high-speed trains and specific drive routes to understand 

​

The Results

• Improved network performance was achieved with the device-agnostic approach, especially in areas the competition was offering a better standard and supply of service

• Better management of the VoLTE and VoWiFi rollout with an automated assessment of POLQA audio scores, without user input

• Conduction of a study to measure the impact of call quality on delivered customer service quality

• Significant cost reduction by maximisation of test simulators and existing complex hardware set-up efficiency, with comprehensive reports

• Easy to use and 24/7 scalable solution

• No additional equipment and no footprint on the existing test environment
