Product overview
CAKRA overview
Drive-test evidence, engineering reports and virtual RF planning in one workspace.
What is CAKRA?
CAKRA is a browser-based workspace for reading drive-test measurements, investigating radio patterns and communicating engineering findings. It connects session metrics, charts, GPS routes and events so you can examine a finding in its original context.
Alongside measured analysis, Virtual Drive Test provides a separate planning workspace for radio, antenna and route assumptions. Use CAKRA to review evidence and compare scenarios; validate engineering decisions with authorized field data.

The measurement workspace

What you can do
Use the workspace views for different questions about the same session. The documentation introduces each view and links to its detailed usage guide. A verified account opens the analysis workspace; advanced execution requires Enterprise authorization.
| Feature | Purpose |
|---|---|
| Overview & filters | Understand session identity, sample counts and the selected RF scope. |
| Charts & distributions | Compare recorded trends, quality bands and throughput by signal bin. |
| Maps, playback & events | Locate findings, replay the measured route and review cell transitions. |
| RF analysis | Investigate weak intervals and mobility/PCI candidates with their evidence. |
| Cici | Ask contextual questions about the active filtered measurement summary. |
| Report / Print & exports | Prepare a portable PDF and supporting JSON, CSV or GeoJSON for review. |
| Virtual Drive Test & RNO import | Configure sites, antennas and routes; compare predictions and import a structured configuration. |
| Link budget & capacity | Review independent DL/UL planning and per-cell KPI diagnostic hypotheses. |
From findings to a shared review
Report / Print packages the selected evidence into a journal-style document with section navigation, figures, tables and engineering notes. Supporting data exports help colleagues check the source and reuse the selected measurements.
VDT, RNO configuration import and link budget support scenario planning. Keep completed predictions and their assumptions separate from measured evidence; a prediction is not a field measurement or a guarantee of coverage.
Find the guide you need
New to CAKRA? Start with account and browser preparation, then open the import guide for your first measurement session. For an existing session, choose the feature guide directly from the sidebar.
The guides combine explanations, practical steps and annotated application snapshots. Hover, focus or tap a highlighted object to read its note. Search finds feature names and technical terms; the page outline jumps to a section.
Privacy, evidence and help
Measurement files are processed in your browser. Sign-in, access checks, basemaps and AI-assisted questions have their own online boundaries. Temporary session storage is not a permanent project archive: retain source files and export results you need to keep.
Use the privacy and technical-basis guides to understand those boundaries. If something does not work, the troubleshooting guide explains what to check and what sanitized information to send to support.
Evidence-based virtual studies
VDT now separates campaign screening, bounded empirical fitting, field-acceptance evidence, external ray/channel review and mathematical experiments. A passing software check or synthetic preset is not a field-accuracy claim. You can inspect exclusions and preserve exact inputs before deciding what needs another measurement campaign.
History offers portable project snapshots and a local immutable revision ledger. Review, compare and merge revisions without applying them automatically. Export session-only history before closing the page.
Find your workflow
Start with the kind of evidence you have. Measurement logs belong in Import and the analysis workspace; per-cell ROP KPIs belong in Capacity diagnostics; a planning configuration belongs in Virtual Drive Test. Mixing these file types does not make the missing inputs valid.
The guides below cover each user-facing workflow, inputs, review steps and output. Screenshots are practice captures: hover a highlighted region, tap a note or use Tab + Enter to read what the actual control does. Long explanations are also available from question-mark guidance in the app.
