Who teaches the 5G NR courses on CafeTele?
Abhijeet Kumar — a 5G RAN and Core engineer with 10+ years in mobile networks, from 3G/4G modem firmware to 5G NR L2 stack production deployments. Founder of CafeTele and author of the 5G Core Hands-on Lab. Every course cites 3GPP spec sections, every diagram is built from scratch, every animation is synced to narration to the millisecond.
Are the courses suitable for engineers new to 5G or O-RAN?
Yes — each course is structured from foundational concepts up to advanced spec-level detail. The PDCP course assumes basic 5G NR familiarity. The O-RAN course assumes basic mobile network concepts (4G/5G). All courses provide 3 free preview lessons so you can confirm the style works for you before purchase.
How is CafeTele different from YouTube 5G tutorials?
YouTube tutorials are usually slide-deck recordings. CafeTele courses use a custom-built animation engine where every diagram is drawn from scratch and synced to narration beat-by-beat. Every claim cites a 3GPP spec section. Every IE is shown on-screen as it is named. Hands-on labs use real configs and real log excerpts you can reproduce on your own laptop.
Does CafeTele cover NTN (Non-Terrestrial Networks)?
Yes — NTN (Non-Terrestrial Networks · 3GPP Rel-17/18/19) is covered as part of the 6G + Release-20 course, with lessons on LEO satellite orbital mechanics, Doppler compensation, NB-IoT-NTN and IoT-NTN, store-and-forward modes, and the regulatory/spectrum view. Standalone NTN deep-dive course is planned for 2026 Q3 — existing subscribers will receive it free.
What 5G labs are available on CafeTele?
10+ browser-based 5G labs covering 5G NR PHY (SSB, PRACH, PDCCH, PDSCH/PUSCH), 5G Core SBA (Open5GS + UERANSIM with AMF/SMF/UPF/AUSF/UDM walk-throughs), O-RAN (xApps, rApps, Open Fronthaul 7-2x decoder), NTN orbital simulator, IMS registration, network slicing playground. All labs run in the browser — no VMs, no installs, no SDR needed for protocol-level work.
What is included in CafeTele lifetime access?
