4G LTE and EPC

The network most of the world still runs on

Who this is for

Anyone starting in mobile core, and 5G engineers who keep hitting EPC concepts they were never formally taught.

What you will be able to do

  • Walk through an attach procedure and name every message and its purpose
  • Read GTP-C and GTP-U in a capture and follow the TEIDs
  • Explain default and dedicated bearers well enough to design one
  • Debug an attach reject from the cause code alone

Prerequisites

None beyond IP networking. This is the foundation track.

Common questions

How do I get access after I pay?

Pay by UPI, upload the payment screenshot on your order page, and we verify it and send your login details by email and WhatsApp - usually within a few hours.

Which course should I start with?

If you are new to the core network, start with 4G LTE and EPC. If you already know 4G, go straight to 5G Core. Not sure? Message us on WhatsApp and we will suggest one.

Can I watch on my phone?

Yes. Lessons play in the browser on any phone, tablet or laptop - there is nothing to install.

How are the lessons released?

Week by week from your start date, with a short quiz after each module so you can check your understanding.

Do I need my own lab or equipment?

No. Every procedure is shown on our own live core, with the real messages and traces, so you can follow along without any equipment.

Can you train my whole team?

Yes. We run corporate batches with a syllabus built around your technology and your rollout. See Corporate training, or contact us.
