TEMS NLA story – Automate your site acceptances for faster 5G rollouts

The time and skills required for validating new sites are often a significant bottleneck in 5G roll-outs. TEMS Automated SSV, centrally defines testing routines and criteria, identifying what to test, where to test and how to get there. When in location, it automatically conducts the tests, meaning even people with no RF expertise can test for you. This simplified and guided drive testing approach helps you get your 5G network to market faster.

Highlights and innovations


Precision Drive Testing

Operators can’t afford for their highly qualified RF engineers to be driving around manually testing; it’s time to automate. Our Precision Drive Testing methodology transforms the drive testing process from being engineering driven to AI/ML data driven, from manual to autonomous, and from something only skilled engineers can do to something that can be done by anyone. All of which significantly reduces the cost and time of 5G drive testing.

User Experience Testing

Infovista’s user experience testing portfolio enables operators to accurately measure subscriber experience for all native and OTT applications and services by combining machine learning algorithms with sophisticated traffic modeling. It includes solutions for native voice services such as VoNR and VoLTE, OTT voice services, OTT video streaming, and interactive services such as e-gaming, remote drone control and video conferencing.

Voice Quality Testing with sQLEAR

sQLEAR is our ITU-certified audio quality testing (MOS scoring) algorithm for VoNR, VoLTE and OTT voice quality testing. An innovative machine learning-based approach to measuring and assuring speech quality. It uses a combination of network parameters, codec/client information and reference audio to predict MOS scores with proven high accuracy. sQLEAR scores are comparable between device models and suitable for benchmarking scenarios.
