What you'll master

Seven parts that walk the entire layer — not a list of fields, but the why behind every procedure, so you can read MAC like a sentence.

🧱

Foundations

Where MAC sits, the entity & reset, the full channel map, and the five core functions.

📶

Getting on the air

Random access (4-step & 2-step), power ramping, contention resolution, and timing advance.

🔁

Moving data reliably

DL & UL HARQ, NDI/RV, soft combining, and the logical-channel prioritisation token bucket.

📨

Asking & reporting

Scheduling Request, Buffer Status Report, and Power Headroom — the uplink advocacy chain.

🔋

Saving energy & spectrum

DRX cycles, bandwidth parts, carrier aggregation and SCell activation.

📡

Beams, control & the wire

Beam failure recovery, the full MAC control-element catalogue, the PDU format, and sidelink.

The full 21-module curriculum

Each module is a cinematic, narrated walk-through with full-canvas animation and word-by-word karaoke captions — audio-synced to the visuals with zero drift.

Three reference books included free

Beyond the 21 videos, every enrollment comes with three companion references — the same material, three ways to study it.

📖

Theory Deep-Dive

An animated 10-section reference: stack, entity, channels, functions, procedures, and complete tables for timers, control elements, the PDU format and the KPI map.
🧮

Formula & Parameter Cheat-Sheet

Every equation an engineer reaches for — power ramping, timing advance, HARQ, BSR/PHR, the LCP token bucket, DRX arithmetic — with a full RRC parameter-range table.
📕

The Book — read-through

A 19-chapter textbook narration of the whole layer in flowing prose, for when you want to read rather than watch.

Built for

If you read 3GPP specs, decode logs, optimise networks, or interview for 5G roles — this is your MAC course.

Students & Researchers

Mastering 3GPP Rel-19 from first principles

Frequently asked

Is this course 3GPP-accurate?

Yes. Every procedure, timer, control element, formula and PDU field is keyed to 3GPP TS 38.321 v19.1.0 (Release 19), with parameter enumerations from TS 38.331. Clause references are cited throughout so you can verify against the spec.

What's the level — do I need prior MAC knowledge?

It's an advanced course, but it builds from first principles. Basic familiarity with the 5G NR stack (SDAP / PDCP / RLC / MAC / PHY) helps, but no prior MAC-layer knowledge is required.

What's included besides the 21 videos?

Three reference companions — an animated Theory Deep-Dive, a Formula & Parameter Cheat-Sheet, and a full 19-chapter textbook read-through of the entire layer.

What about the ₹4,999 / $49 original price?

That's the standard post-launch price. The current ₹599 / $9.99 is a launch offer — lock it in now for lifetime access.

What payment methods do you accept?

All major methods via Razorpay: UPI, credit/debit cards, net banking and wallets for Indian customers; international cards globally. Pricing auto-detects your region (₹599 in India, $9.99 globally).

Do I get lifetime access?

Yes — one payment, lifetime access, and all future updates are included free.

Does it work on mobile?

It works best on tablet and desktop (the animations are densest on a 1024px+ screen). Mobile is supported and the audio narration works everywhere.
