Ten cinematic, cue-synced modules that decode the Open Fronthaul on the wire — from the 7.2x split to section types, block-floating-point IQ, PTP timing, the RIC and O-Cloud security. Every claim cited to the O-RAN ALLIANCE specs and 3GPP. Not slides — engineering.
Every diagram animates in sync with the narration, every field is decoded from real bytes, and every fact is quoted from the exact O-RAN clause — so you can debug a live fronthaul capture, not just recite an acronym.
Content taken word-for-word from O-RAN.WG4.CUS.0, MP.0, WG3 E2SM, WG11 security and 3GPP — with the clause on screen.
The player is a live stage: headers assemble field-by-field, section types light up, beams steer — exactly as the narration reaches each idea.
Seven labs with scenarios, numbered test cases and worked solutions — bandwidth dimensioning, U-plane decode, sync budget, NETCONF debug and a capstone.
Decode an eCPRI frame, a C-plane section header, a block-floating-point IQ sample and an eAxC identifier — by hand.
Trace an energy-saving decision from an rApp in the Non-RT RIC, through A1 and E2, down to antenna elements going to sleep on the fronthaul.
Each module ends with a spec-cited quiz. Finish the course and earn your CafeTele certificate. Lifetime access, learn at your pace.
Chapter 1 is free — no sign-up, just press play. The rest unlock with full access.

Builds and optimizes live 5G RAN networks and hands-on labs. This course distills real integration work into a spec-exact, wire-level walkthrough — the way an engineer actually reads the fronthaul. Also the author of CafeTele's 5G Core, NR PHY and NTN masterclasses.
Yes — Chapter 1, "The O-RAN Architecture", is completely free. No sign-up, no card. Just press "Watch Chapter 1 — Free" and it plays. It's a full 30-minute advanced module, so you can judge the depth before you enroll.
RAN / 5G engineers, integration and O-RU/O-DU teams, test & certification engineers, and anyone who needs to work with the Open Fronthaul at wire level. It's advanced — comfortable with 5G NR basics helps, but every concept is built from the spec.
Every module is a cinematic, cue-synced video: diagrams animate in time with the narration, headers assemble field-by-field, and one downlink slot is traced end-to-end. Plus seven hands-on labs with worked solutions. You learn to read the bytes, not memorize acronyms.
O-RAN ALLIANCE WG1 (OAD architecture), WG4 (CUS.0 control/user/sync planes, MP.0 management plane), WG3 (E2SM-KPM/RC), WG11 (security), WG6 (O-Cloud/O2), plus 3GPP references. Clauses and versions are shown on screen.
Yes. One payment gives you lifetime access to all modules, labs and any future updates, and you earn a CafeTele completion certificate after finishing the quizzes.
Yes — the course is fully in English, with English karaoke subtitles you can size up or down in the player.
