PRESS RELEASE


INFOVISTA LAUNCHES PRECISION DRIVE TESTING™ TO AUTOMATE 5G TESTING

Cloud-native automation of testing routines integrates data from across 5G
network lifecycle to increase speed and accuracy

Paris, France – April 12th, 2022 – Infovista, the global leader in network
lifecycle automation (NLA), today announced Precision Drive Testing™ to bring a
ML/AI data-driven approach and automation to network testing, significantly
reducing the cost and time of 5G network testing. The patent-pending Precision
Drive Testing leverages 5G network, service and customer data, and ML/AI
techniques to increase the speed and accuracy of 5G testing process. 

“There’s a misconception that 5G makes drive testing redundant, but the reality
is that although enhanced from LTE, the ‘minimization of drive testing’ feature
in 5G still only works if users are in the geographic area that needs testing.
Drive testing will still be needed to complement the gaps of MDT in testing, at
least until 5G is in fully autonomous,” said Dr. Irina Cotanis, Technology
Director, Network Testing at Infovista. “But such is the complexity of 5G
networks and the proliferation of device types that traditional drive testing
processes are not fit-for-purpose. Operators can’t afford for their highly
qualified RF engineers to be driving around manually testing; it’s time to
automate and make the cloud do the heavy lifting. Precision Drive Testing
transforms the drive testing process from being engineering driven to AI/ML data
driven, from manual to autonomous and from something very few can do to
something that can be done by anyone.”

Infovista’s cloud-based Precision Drive Testing solution automates and guides
testing triggered by use cases based on information and/or analytics results
from network planning and performance, fault and configuration management,
services assurance, and customers’ (or Crowdsource) data, which an operator will
use to inform and improve the network lifecycle processes. Results are instantly
available as actionable insights to be used by the requesting systems/solutions,
creating a closed-loop of automated and guided testing. This reduces testing
time and effort and improves the accuracy of service-specific testing KPIs.

When triggered, the Precision Drive Testing use cases automatically calculate
the best test route, generate test scripts to run along with their Definition of
Done criteria, the correspondent KPIs log masks and context sensitive criteria.
The automatic calculation of sweet spots and drive routes, coupled with
directions to the tester including error handling and Edge Analytics, improve
the speed and accuracy of the testing processes. Finally, real time reporting
and data feed of the expected result ensures that testing data is quickly acted
up and in turn used to inform network/service/customer data source based on
which the drive has been triggered. 

Use cases that can trigger Precision Drive Testing across the 5G network
lifecycle include, but are not limited to:

 * Automated Single Site Verification (SSV) – Powered by Precision Drive
   Testing, the Infovista Automated SSV solution directs lay people using
   commercially available smartphones to conduct tests in the field, leaving
   valuable engineering expertise free to focus on high value network
   optimization tasks. Site testing routines and criteria are defined at the
   backend and key measurements are autonomously evaluated against pre-defined
   thresholds rather than manually by a field engineer. This reduces errors in
   data collection and accelerates the time to Definition of Done status in
   network-wide testing processes
 * Fine tuning 5G planning propagation models – The solution identifies when the
   5G propagation model is likely to be less accurate due to varying external
   factors, for example in areas of known building construction, fast growing
   trees, or in extreme and challenging locations such as quarries and container
   ports where the landscape changes frequently. Precision Drive Testing enables
   to get actual live data that then can improve the model and accelerate the
   planning of public and private 5G networks
 * Network Acceptance Automation – ‘Site acceptance’ routines in multiple
   conditions have a challenge using real traffic with enough samples,
   particularly in greenfield networks. This means if a problem occurs when real
   traffic starts running, it can be a time-consuming and costly process to
   identify the underlying problem. In triggering Precision Drive Test, the
   algorithms identifies the sweet spot for testing the live network, define the
   testing routine, direct the tester to the site and automatically conduct the
   tests. This reduces the time and cost of 5G network acceptance through
   automated and highly specific testing processes
 * Geolocated troubleshooting – Deeper and more advanced assurance can detect
   problems and prompt Root Cause Analysis for troubleshooting. But if the
   problem still exists, it can then trigger a Precision Drive Test to get
   precise fine-grained geolocated data to help solve issue such as
   ‘Inter-vendor Ping Pong Handover’ that have been detected by the assurance
   system
 * Proactive network health monitoring – Monitoring a network to ensure delivery
   of the end-user experience, for example for a network’s top 10 VIPs, can be a
   labour intensive and unforgiving process. The software can identify and
   define drive testing routes, such as a VIP’s commute, and trigger Precision
   Drive Testing to test degradations/problems on the routes and proactively
   automate regular quarterly drive tests
 * Assurance of Critical Networks – The growth in private networks, and in the
   future 5G network slices, will see more widespread deployment of uRLLC-based
   services such as remote control of mining equipment or drone surveillance of
   utilities’ critical national infrastructure. These critical networks require
   predictive SLA management. Assurance software can trigger a Precision Drive
   Test to proactively test critical networks, with assurance processes in turn
   improved and optimized through the input of live network test data

Infovista’s TEMS Network Testing Portfolio enables network and services
performance quality evaluation, troubleshooting and optimization by measuring
and benchmarking end user experience.  For Network Operators and Regulators,
TEMS delivers the ability to walk test, drive test, and dynamically analyze
network and services performance under real-life conditions—indoors, outdoors,
and around the clock.  For more on the Infovista TEMS network testing portfolio,
