Takwa Sebai RAN validation and RCA

RAN evidence toolkit · English field edition

Make your RCA survive the handoff.

A fillable 5G NR workbook for engineers who must show where the evidence changed, what remains unknown and which test comes next.

I built the working copy I wanted beside me when a plausible cause was starting to sound like a proven one.

Final cover of Takwa Sebai's RAN Evidence Toolkit showing a real anonymised HiCellTek application capture
Exact final cover. The HiCellTek capture is real and anonymised. The observed result is shown; the physical cause is not claimed.

01 / Real product evidence

This is not another KPI glossary.

The workbook starts from a decision an engineer must defend. It records the test contract, identities, clocks, last positive evidence, first divergence and next discriminating test.

Observed

5G NSA, HTTP POST and application uplink are visible together.

Not proven

The frame alone does not identify RF, scheduler, transport or policy as the cause.

Next move

Change one controlled factor and keep the evidence clocks aligned.

03 / The working method

The hard part is not finding another possible cause.

  1. 01 Freeze

    Direction, endpoint, protocol, duration, clock and metric.

  2. 02 Align

    UE, cell, node, session, interval and evidence source.

  3. 03 Locate

    Last positive evidence and first synchronized divergence.

  4. 04 Test

    One controlled comparison that can separate explanations.

  5. 05 Hand off

    Conclusion, remaining uncertainty, action and post-check.

04 / Why pay when AI can help?

An AI can suggest ten causes in seconds.

It does not know whether your clocks align, whether the value is observed or inferred, or whether the evidence may be shared.

The toolkit gives the AI, and the engineer reviewing its answer, a fixed contract. Source. Scope. Observation. Falsifier. Stop rule. Report boundary.

That structure is the product. The goal is not to replace your judgement. It is to make your judgement inspectable.

Final engineering handoff page with fields for scope, test contract, evidence, conclusion and remaining uncertainty
The final handoff keeps the conclusion and the unproven remainder visible on the same page.

05 / Licence and boundaries

Use it for your work. Keep the blank toolkit private.

One named buyer may fill, save and print the toolkit across unlimited authorised professional or freelance investigations.

The personal licence allows

  • Create and retain multiple completed case copies.
  • Include completed findings in a report for an employer or client.
  • Adapt your own written conclusions after using the method.

The purchase does not include

  • A HiCellTek mobile application, Analyzer or cloud licence.
  • HLOG files, customer evidence, operator data or individual RCA.
  • A meeting, call, consulting service or guaranteed root cause.

06 / Field edition

A working instrument, not a training promise.

Download the complete ZIP, keep the blank master unchanged and create a new local copy for each authorised investigation.

No subscription. No call. No evidence upload. Your case data stays in the local copies you control.

Sold by HiCellTek, Takwa Sebai's French individual business. Your investigation data is never requested or uploaded.

07 / Before you buy

Questions an engineer should ask first.

Does the toolkit analyse my HLOG?

No. It structures evidence and conclusions. HiCellTek Analyzer and HLOG processing are separate products.

Does it guarantee that I will find the root cause?

No. It helps you locate the first defensible divergence, reject unsupported claims and define the next test.

Can my team share one licence?

No. The included licence is for one named buyer. Completed findings may be shared; the blank toolkit may not.

Do I need Adobe Acrobat?

Adobe Acrobat Reader is the safest default. A compatible browser PDF viewer may work, but saving and reopening should be checked before a live case.

Is the worked example a customer result?

No. Its values are explicitly declared synthetic. The real HiCellTek capture proves the observed product context only.
