"We have used viSer ro complement existing solutions as it gave us a different view of the customer experince. Its now part of our main set up"

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 where 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

"All the elements we needed to automate our tests were successfully brought together with SmartViser, the support and the test solution. We have doubled our testing load and halved the testing time. We have both won on both sides!"

The Challenge

  • Company restructuring resulting in reduced manpower

  • Increased workload with the introduction of new technology like VoLTE/VoWiFi

  • Ensuring repeatability and consistency of the testing

The Solution

  • viSer full test automation of existing test plan to test all key use cases like

  • Call Performance & Voice Quality

  • Data performance / Bearer testing

  • Battery life measurement

  • VoLTE & VoWiFi 

  • Audio MOS on any device

The Results

  • Increased Test Efficiency. Increased number of devices being tested.

  • Achieved a reduction of time by 75%

  • Achieved ROI 40%

"Thanks to viSer we were able to continue testing uninterrupted. Enhanced testers motivation and reduced the time they spent on the road performing mobility testing"

The Challenge

  • Covid-19 social distancing restrictions mean no more than one person in a car while testing

  • General Safety when one person had to carry out field testing while driving

The Solution

  • viSer full test automation to test all key use cases like Call Performance, Voice Quality, Data performance, handovers

  • Test Scripts creation with required conditions to ensure testing starts is specific Cell ID, RAT, IMS Reg Status etc.

The Results

  • Increased employee safety 

  • Reduced Test times 

  • Adhered to guidelines regarding social distancing.

  • Part of business continuity and process improvement

EU Operator

"Thanks to viSer we were able to continue monitoring our network esepcially on the new technology like 5G which was not covered by the existing solution"

The Challenge

  • Complex setup of Network Monitoring in place that does not allow update of test cases, especially with the introduction of new 5G Technology. Costly update of existing solution.

  • Looking to test with the most popular devices in the market/ What their end users are using when one person had to carry out field testing while driving

The Solution

  • viSer full test automation to test Calls, Messages, Data transfer, browsing performance

  • Alerts are generated by viSer to an email address when a test case fails twice

  • Commercial end-user devices used

The Results

  • Easy to update test scenarios 

  • Already using viSer so the cost of the setup was 1/10 of the existing system upgrade

  • Portable to use in any location needed to monitor performance 

Multi SIM Testing

EU Operator

"We are very pleased with the set up, we saved over 90% if time managing the testing and we only need 4 devices to test 40 different SIM set ups"

The Challenge

  • Complex set-up testing manually 40 different SIM cards with 40 devices to check all provisions work correctly

  • Frequent mistakes in managing all devices

  • Open Market Testing and time spent to insert SIMs

The Solution

  • Smartboard hardware device that can support 10 different SIM cards connected to one device with a flex cable

  • Python controlled

  • viSer set up to automate testing on each SIM card

The Results

  • Easy to update test scenarios 

  • Already using viSer so the cost of the setup was 1/10 of the existing system upgrade

  • Fully automated reducing the need for technical staff to monitor and test

  • Only 4 devices are required reducing cost and risk of device failure

  • Time savings of 90%
