📡 Where do you start with 5G?
5G has a lot of moving parts: architecture, procedures, interfaces, O-RAN and logs. If you jump in randomly, it gets confusing fast. Here is the order that makes sense to me.
🗺️ A simple learning path
1. Basics of 5G SA and NSA
Understand the two architectures and how the end-to-end procedures work.
2. Signalling and sessions
RRC, NAS, PDU session, QoS and mobility. This is where most real-world issues show up.
3. Interfaces
Learn what each one connects: F1AP (CU and DU), NGAP (gNB and core) and E1AP (CU-CP and CU-UP).
4. O-RAN basics
RU, DU and CU architecture, the 7.2x split, M-Plane, RIC, SMO, PTP and SyncE.
5. Log analysis
Read real QXDM and QCAT logs. This is where the theory finally clicks.
💡 One tip
Don't just read the specs. Match each procedure with a real log. You will remember it far longer.
