01 / MEASURE
Bring the trace
Read a field log with its route and event context.
- Timestamped samples
- GPS route & cell context
- KML event pairing

CAKRA.
Trace the signal.
Understand cell handover.
Move from raw drive-test evidence to an RF review and VDT scenario—without uploading the source file by default.
Raw logs are processed locally in your browser. We use no third-party analytics or error-tracking service; usage metadata stays on CAKRA servers.

FROM TRACE TO DECISION
One operating view for the RF work around a drive.
CAKRA keeps evidence, interpretation, and a planning scenario distinct—so the team can see what was measured and what is still an estimate.
02 / INSPECT
Find the pattern
Move from raw KPI variation to a segment worth investigating.
- Coverage-gap candidates
- Handover timeline
- Filterable RF evidence
03 / PLAN
Test the next move
Set site and antenna assumptions, then compare the scenario with the trace.
- Versioned VDT scenario
- Measured vs. estimated
- Exportable review trail
ENGINEER IN CONTROL
CAKRA organizes the analysis. Field validation and network change approval remain engineering decisions.
Before you start
Frequently asked questions.
Which log formats can it read?+
Best supported: G-NetTrack TXT export + matching _events.kml. Recognized-header CSV files also import fine. TEMS, NEMO, or SIGMON exports need matching columns; vendor binary formats aren’t supported yet.
Where is data processed and stored?+
Parsing happens entirely in your browser. The dataset is stored temporarily in IndexedDB for this tab session. Refreshing keeps it; a new tab session needs a fresh import. Use "End session" to clear it when you’re done.
Is data sent off the device?+
The raw file itself is never uploaded by the app. Assisted analysis receives only the question and bounded metric summary when you request it. The map service receives tile requests for the area you’re viewing.
Do I need an internet connection?+
The app needs to load first. Once loaded, parsing and statistics run in the browser. The base map and assisted analysis need a connection; if the base map fails, data layers and the 2D view still work.
How do I get access?+

Is the 3D prediction the same as an RF measurement?+
No. Measurements come from the log; VDT is an estimate based on scenario parameters. Buildings provide visual context and aren’t yet factored in as propagation obstacles.
