The industry's most comprehensive analytics suite built on mobile network testing data

TEMS Discovery Device gives you unparalleled insight into network performance as perceived by your subscribers. It ingests the complete TEMS measurement portfolio and also supports logfiles from other network testing vendors — so you benefit from the same advanced analytics whatever your data collection method.

Capabilities

Everything between the logfile and the decision

Import, correlate, visualize, diagnose and publish — automated end to end, so engineers spend their time on root cause instead of file handling.

Analyze and troubleshoot 5G NR

In-depth UE and scanner cell measurements plus NR cell configuration analysis, so 5G NR issues are addressed with evidence rather than guesswork.

Manage large test data sets

Data is processed once and stored permanently. Multi-hour, multi-device campaigns stay queryable instead of being re-parsed on every session.

Analyze subscriber experience at multiple levels

Insight into network performance as perceived by subscribers — at the device, application and network level — for a full 360-degree view of experience.

Identify problems faster

Analytics dashboards, reports and RF diagnostics tools surface the issues actually affecting subscribers, ranked and mapped instead of buried.

Deep dive into test data

Drill down at the device, application or network layer. L1-to-application correlation turns the hardest intermittent faults into a readable message flow.

Report across the organization

Create, share and customize reports for multiple audiences — executive summary for C-level, engineering detail for the field team, generated and distributed automatically.

Use cases

From collected measurement to corrected network

01

Automate network testing data processing

Collecting many hours of drive-test data is only half the job — analyzing it manually can take just as long again. TEMS Discovery Device automates the chain from file import to script execution, problem-set categorization and the generation and sharing of reports, returning days of engineering capacity per campaign.

  • Import from TEMS Investigation, TEMS Pocket, TEMS Paragon and third-party logfiles
  • Scheduled and event-driven processing chains without operator intervention
  • Versioned datasets: process once, query forever

02

Identify problems captured during testing

Network issues hide inside massive data sets and only appear when the data is looked at in several ways at once. Dashboards, reports and RF diagnostics let you uncover subscriber-affecting problems earlier, get to root cause quickly, and hand network quality teams a fix list instead of a raw dump.

  • Coverage, quality, interference and accessibility viewed side by side
  • Automatic problem-set aggregation by region, sector group or condition
  • RF diagnostics for pilot pollution, overshooting and neighbour conflicts

03

Troubleshoot performance issues

Networks evolve constantly, so issues will arise. TEMS Discovery Device lets you drill into any data collected during the tests — device, application or network level — giving engineering teams the depth needed to resolve even the most difficult performance problems before they degrade quality of experience.

  • Synchronized map, chart, table and message views on one timeline
  • Application-layer KPIs correlated against radio conditions
  • Replay any event boundary-by-boundary across technologies

Automate project reporting

Keeping every stakeholder informed during a large testing project is critical and time-consuming. TEMS Discovery Device automates creation and distribution of reports targeted at specific audiences — an executive summary for senior management, a detailed report for engineering management, and full-detail reports for the engineers themselves.

  • Reusable report templates with audience-specific depth
  • Scheduled generation and e-mail distribution
  • Consistent KPIs across every project and region

Editions

Four functional levels — scale from a single logfile to an enterprise analytics platform

Each edition is a superset of the one before it. Choose the depth your workflow needs today and upgrade without changing your data or templates.

Technologies & data sources

One analytics layer for every generation you still operate

From 5G NR standalone field trials to legacy CDMA audits, TEMS Discovery Device decodes and correlates measurements across the full radio stack — and accepts logfiles from other network testing vendors, so the analytics do not depend on who collected the data.
