Session 4 of my 4G End-to-End Signaling free course is now available on YouTube

In Session 4 of the 4G End-to-End Signaling Course, we break down LTE RRC states, RRC Idle vs RRC Connected, LTE to 5G state transitions, and the role of ECM and EMM states in the EPC/core network.

You will learn how the UE is viewed from both the radio access side and the core network side, including how paging, mobility, handover, cell reselection, and service reachability work in LTE networks.

Session 4 of my 4G E2E Signaling Course will be available tomorrow, 20 April 2026, on my YouTube channel.




This session is a direct continuation of Session 3. While Session 3 focused on the overall LTE picture, including the architecture, main nodes, and interfaces, Session 4 moves one step further to explain RRC, ECM, EMM, and the mapping between them.




This is an important transition point in the course, because after Session 4, we will start the deep dive into the end-to-end signaling procedures.

Session 3 of my 4G End-to-End Signaling free course is now available on YouTube. In this session, I cover the LTE network architecture from both the RAN and EPC perspectives, including the main node functions such as eNB, MME, SGW, PGW, HSS, PCRF, and EIR. I also go through the key interfaces and protocols used between these nodes, explain the difference between control plane and user plane, and give a brief introduction to physical connectivity, virtualization, and Cloud EPC concepts to support the upcoming signaling sessions.

One of the improvements I am trying to add to my content, beyond the usual RAN and end-to-end signaling topics, is to gradually open the door to adjacent areas that are becoming more important for telecom engineers.

Along with the RAN and E2E learning path, I want to start adding both theoretical and practical exposure to:

- Cloud and Cloud-Native
- AI / ML
- Open RAN

The main idea is not to move away from telecom fundamentals, but to help RAN and E2E engineers build a wider technical vision, better understand where the industry is moving, and open a wider view of market opportunities.

At the same time, I also would like to highlight that I am learning in parallel while preparing and recording these new videos. I am not yet expert in these areas but i do believe that i can connect the dots between theoretical and practical understanding, and part of this journey is to keep learning, simplifying the concepts, and sharing that learning path step by step.

As part of this direction, next session in my 4G End-to-End Signaling course will introduce:

- Legacy Virtual EPC (vEPC)

- Cloud-Native EPC architecture


The target of this session is not to go too deep into cloud details, but to build a clear high-level understanding of the concepts, the architecture evolution, and why this topic matters for telecom engineers today.

My goal is to keep connecting the radio side with the wider end-to-end ecosystem around it, while continuing to grow in these topics together with the audience.

Stay tuned.

Finally, my new voice kit has arrived.

One of the main comments on my videos was about voice quality not always being stable, so this was an important step for me. It was delayed a bit, but better late than never.

A lot of effort goes into preparing the materials, and that effort deserves trying to deliver the content with clear sound and better overall quality.

This should help me record clearer YouTube videos and courses in the coming period.

Step by step, trying to make the content better.

This week, I’ll be sharing Session 3 of my 4G End-to-End Signaling Course. Sessions 1 and 2 explained how the UE gets onto LTE, Session 3 explains what happens next.




In session 3, we move from access basics into the bigger LTE picture:

network architecture, key interfaces, RRC states, ECM/EMM states, and how they all fit together.




The goal is to make the LTE signaling story easier to follow before we move deeper into the next procedures.













Stay tuned this week.

*Note: the video was slightly delayed due to a cold/flu, which also had a small impact on my voice in the recording.

Stay tuned for Session 2 of my 4G E2E Signaling Course which will be released by 30~31 March 2026. 📶

In this session, I will continue covering the main 4G access foundation concepts in a simple and practical way.


The session will focus on key topics such as RACH basics, RRC states, mobility, paging, tracking area update, call flows, network nodes, interfaces, and protocols.

You can also watch Session 1 from the link provided below.

The first session of the 4G E2E Signaling course will be available soon. This session is designed to build the right foundation before we move into the detailed signaling flows.


We will cover the main 4G access/mobility fundamentals, including PLMN, Cell Search, System Info acquisition, Cell Selection, TAC/TAI, Cell Reselection, RACH basics, RRC states, handover overview, E2E 4G network architecture, interfaces, protocols and more.

The aim is to give a clear background so the full E2E signaling procedures become easier to understand later.

Please subscribe to my YouTube channel so you do not miss the upcoming sessions of the 4G E2E Signaling course. The channel is designed to explain complex telecom topics in a simple, practical, and easy-to-follow way.

Stay tuned for Tableau Training – Session 6: Advanced Maps 🗺️

Working with maps is one of the most powerful tools in data analytics. It helps reveal patterns that are often impossible to see in tables or charts. In several real projects using crowd-sourced network data, map analysis helped us quickly identify transport bottlenecks and problematic sites generating the lowest DL speeds, etc.. By combining distance calculations, nearest-site analysis, polygons, sector locations, and spatial categorization, we were able to visualize network issues clearly on the map and focus optimization efforts where they mattered most.

In this week’s session we’ll cover Advanced Mapping techniques in Tableau, including:

• Spatial data types and spatial files
• Key spatial functions (MAKEPOINT, DISTANCE, BUFFER, MAKELINE, INTERSECTS)
• Spatial joins and point-in-polygon analysis
• Dynamic buffers and counting points within coverage areas
• Multi-layer map design (points + lines + polygons (Sectors, Voronoi, etc.))
