The 5G core, visualized end-to-end.
A 24-chapter cinematic deep-dive into every NF, every interface, and every procedure of the 5G core network. Animated SVG visuals synced to narration, every IE explained, 3GPP-aligned. By Abhijeet Kumar.
Six things this course does differently
Built by an engineer who actually ships 5G core code, 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
UE Registration walked NAS-IE by NAS-IE: 5GS Reg Type, ngKSI, SUCI, UE security capability, requested NSSAI, last visited TAI. Same depth for PDU Session, Authentication, Mobility.
- NAS · NGAP · SBI bodies
- 3GPP TS 24.501 §8 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 chapters on 5G-AKA and SUPI/SUCI privacy with the actual MILENAGE math (f1–f5), KAUSF→KAMF derivation tree, ECIES Profile A/B math, Curve25519 vs P-256.
- RAND · AUTN · RES* on the wire
- SIDF + ARPF roles
- SoR · UPU · AKMA · NSAC
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 chapter
- Release 15/16/17 distinctions
- No vendor-specific cruft

Abhijeet Kumar
I've spent the last decade in mobile core networks — from 3G/HSS in production to 5G SA core deployments. 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 deep-dive companion to that lab — the same depth I give in private trainings, distilled into a watch-anywhere format. Every chapter cites a 3GPP spec section, every diagram is built from scratch, every animation is synced to the narration to the millisecond.
One price. Forever.
Pay once. Watch forever. Future chapter additions included at no extra cost.

How CafeTele compares
Other 5G training products are great. They also cost 50–100× more. Here is how the major players stack up for a working engineer.
Most engineers using CafeTele also hold (or plan to take) a vendor certification — Ericsson NRO, Nokia 5G Field, Qualcomm 5G Associate. The CafeTele courses cover the underlying 3GPP standards those vendor certs assume you already understand. Bridging the gap is the wedge.
