Open RAN, visualized end-to-end.
A 24-lesson cinematic deep-dive into the O-RAN ALLIANCE architecture — every open interface, every RIC layer, every xApp + rApp pattern. Animated SVG visuals synced to narration, R005 + 3GPP Rel 18/19 aligned. By Abhijeet Kumar.
Six things this course does differently
Built by an engineer who actually works on Open RAN deployments, for engineers who need to understand it deeply.
Every 5G NF, deeply
Not just AMF/SMF/UPF. Full coverage of UDM · UDR · AUSF · PCF · NRF · NSSF · SEPP · NEF · CHF · SCP · BSF · LMF · NWDAF — what they do, what fields they carry, how they fail.
- NRF NFProfile bit-by-bit
- SEPP N32-c / N32-f / PRINS
- SMF + UPF PFCP rules
Every IE in every message
Open Fronthaul walked plane-by-plane: U-plane IQ + BFP compression, C-plane Section Types 0/1/3/5, S-plane PTP + SyncE chain (GPS→T-GM→T-BC→T-TSC), M-plane NETCONF/YANG. Same depth for E2, A1, O1, O2.
- NAS · NGAP · SBI bodies
- O-RAN.WG4.CUS.0 + MP.0 walked through
- Bonus: PFCP/N4 rule construction
Animated · narrated · synced
Custom SVG visuals (no slide-deck recordings). Audio narration synced beat-by-beat with on-screen elements. Karaoke-style captions track every word.
- ~4500 visual beats total
- Edge-tts narration · clean audio
- Pause / scrub / fullscreen
Security at engineer depth
Two full lessons on O-RAN Zero Trust + M-Plane supply chain security. WG11 threat model, mutual TLS, NETCONF/SSH hardening, software/hardware bill of materials, vendor attestation, and the open M-plane vs hierarchical M-plane debate.
- RAND · AUTN · RES* on the wire
- SIDF + ARPF roles
- SoR · UPU · AKMA · NSAC
O-RAN ALLIANCE + 3GPP aligned · always
Every claim cites a TS spec section. TS 23.501 (architecture), 23.502 (procedures), 24.501 (NAS-5GS), 29.5xx (SBI APIs), 33.501 (security), 38.413 (NGAP), 29.244 (PFCP).
- Reference table per lesson
- Release 15/16/17 distinctions
- No vendor-specific cruft
Lifetime access

Abhijeet Kumar
I've spent the last decade across mobile networks — 3G/HSS in production, 5G SA core deployments, and Open RAN integration projects. I run the CafeTele 5G Core Hands-on Lab (Open5GS + UERANSIM) used by engineers across India, Europe, the Middle East, and Southeast Asia.
This course is the O-RAN counterpart to that lab — the same depth I give in private trainings, distilled into a watch-anywhere format. Every lesson cites an O-RAN ALLIANCE WG or 3GPP TS section, every diagram is built from scratch (WG1.OAD-faithful), every animation is synced to the narration to the millisecond.
One price. Forever.
Pay once. Watch forever. Future lesson additions included at no extra cost.

5 hands-on labs
Once you finish the cinematic lessons, the work isn't done. Stand up a real O-RAN SC Near-RT RIC. Write an xApp. Capture E2AP packets. Push A1 policies. Query a YANG-enabled O-DU. All step-by-step, all on your own laptop.
All 5 labs are bonus content included free with course purchase. Total time ~2.5 hours. Run on your own machine (8 GB RAM, Linux/Mac/WSL).
Common questions
Stop reading slide decks. Start understanding O-RAN.
24 lessons of animated, narrated, O-RAN R005 + 3GPP-aligned deep dives. Lifetime access. Two free lessons first.
