Design and optimise 5G Non-Terrestrial Networks end to end — satellite orbits & payloads, link budget, NR timing & Doppler, SIB19/NTN-Config, 5GC integration and coverage planning. 43 animated, interactive lessons, every number traced to the 3GPP spec.
NTN is where the physics finally bites 5G NR. This course teaches it the only way that sticks — with interactive React-Flow diagrams and calculators you drive yourself, calibrated to the actual 3GPP tables.
A live link-budget calculator that reproduces TR 38.821 Table 6.1.3.3-1 to within 0.06 dB, a coverage-consequence engine, an orbit & constellation dimensioner and a SIB19 / NTN-Config generator.
Values are pulled verbatim from TR 38.811 / 38.821 and TS 38.300 / 331 / 321 / 213 / 214. Illustrative planning figures are labelled as such — no invented numbers, ever.
Timing advance, Doppler pre-compensation, RACH over the void and HARQ stop-and-wait across a 270 ms GEO round-trip — the exact NR mechanisms NTN rewrites, animated frame by frame.
The full NTN-Config information-element tree with verbatim TS 38.331 ASN.1, ephemeris CHOICE explorer and a searchable 69-row IE & parameter reference catalogue.
The complete service-based 5GC over NTN — AMF/SMF/UPF placement (central, edge, on-board), NAS timers over long RTT, discontinuous coverage, mobility and the registration call-flow that must fit T3510.
A 264-question, spec-cited quiz bank across all 5 days, plus a fully-worked hands-on lab track on the real open-source stack — Open5GS, UERANSIM, OpenAirInterface NTN, tc-netem and Skyfield.
A deliberate arc — from the 5G baseline, out to the satellite, down through the radio, into the core, and finally to planning a real constellation.
You know NR and the 5GC — now learn exactly what changes when the cell is 600 km up and moving at 7.5 km/s.
You know satellites and link budgets — now map them onto 3GPP NTN, SIB19, HARQ and the service/feeder split.
Dimension a constellation, compute coverage and capacity, and configure the timing/Doppler/K-offset parameters that make a beam actually work.
RAN, core and satellite engineers who design, integrate or optimise 5G Non-Terrestrial Networks — 5G NR / core engineers moving into satellite, NewSpace and satcom engineers entering 3GPP NTN, and planning / optimisation teams at operators, vendors and satellite operators.
Yes. Every value is traced to a real specification — TR 38.811 / 38.821, TS 38.300 / 331 / 321 / 213 / 214, Rel-17 to Rel-19 — with no invented figures. The link-budget tool reproduces TR 38.821 Table 6.1.3.3-1 to within 0.06 dB, and illustrative planning values are clearly labelled as such.
A one-time payment of $49 (₹4999 in India) via Razorpay (cards / UPI / Apple Pay / Google Pay) or PayPal gives you lifetime access to all 5 days, 43 interactive lessons, the 264-question quiz bank, the IE reference and the hands-on lab guide.
Design an NTN deployment end to end: pick the orbit and payload, compute the link budget and coverage, configure NR timing advance, Doppler compensation, RACH/HARQ and SIB19, integrate the 5G core and mobility, and plan capacity for LEO/MEO/GEO constellations.
No. Every tool runs in your browser, and the hands-on lab track is fully emulated on free open-source software (Open5GS, UERANSIM, OpenAirInterface NTN, tc-netem, Skyfield) — all timing, delay and link-budget figures come from real 3GPP equations and tables.
Join CafeTele's Practical 5G NTN Engineering course and go from the 3GPP baseline to a planned constellation — one animated, spec-accurate lesson at a time.
