5G Is Not Just About Speed: How Next-Generation Networks Are Built and Why Engineers Should Take the asibiont.com Course

Five years ago, when 5G was just beginning commercial deployment, many perceived it as another step in the evolution of mobile communications — faster than 4G, and that's it. Today, in mid-2026, we see: 5G (and especially 5G-Advanced, described in 3GPP Release 18) has become the foundation for the digital transformation of industry, autonomous vehicles, smart cities, and telemedicine. But to build, operate, and develop these networks, we need engineers who understand not only the physical layer but also software-defined architecture, Open RAN, Network Slicing, and edge computing.

The course "Telecommunications — 5G and Next-Generation Networks" on the asibiont.com platform is designed specifically for such specialists. It doesn't just retell a textbook — it immerses you in the real architecture of the 5G Core and Radio Access Network, provides hands-on experience with the Open5GS and UERANSIM reference implementations in Docker, and most importantly, adapts to your current knowledge level through AI-generated lessons. In this article, I'll tell you what you'll learn, how the training works, and why it's effective for engineers, architects, and technical managers.

What Is a Modern 5G Network and Why It's Important to Understand Its Architecture

Before talking about the course, let's briefly examine what 5G is today. According to industry reports (e.g., Ericsson Mobility Report and GSMA Intelligence), by the end of 2026, more than 50% of mobile traffic will be on 5G networks. But the main change is not in speed, but in flexibility. The 5G Core architecture is built on the Service-Based Architecture (SBA) principle, where network functions (AMF, SMF, UPF, etc.) interact via APIs. This allows dynamic allocation of resources for different use cases:

• eMBB (Enhanced Mobile Broadband) — ultra-high speeds for streaming video and VR.
• URLLC (Ultra-Reliable Low-Latency Communications) — critical applications, e.g., remote control of robots.
• mMTC (Massive Machine-Type Communications) — connecting millions of IoT devices.

Network Slicing allows "slicing" one physical network into multiple logical networks with different characteristics. And Open RAN (O-RAN Alliance) opens interfaces between base stations, allowing the use of equipment from different vendors and the implementation of AI/ML solutions for radio resource optimization.

The asibiont.com course covers all these topics — from the basics of OFDM and Massive MIMO to practical configuration of the 5G Core in containers. Importantly, it does not require deep prior knowledge of telecommunications: a basic understanding of IP networks and Linux is sufficient.

What You Will Learn in the Course "Telecommunications — 5G and Next-Generation Networks"

The program is built around three axes:

1. Physical Layer and Radio Access (5G NR). You will understand how OFDM (Orthogonal Frequency Division Multiplexing), Massive MIMO (multiple antennas), beamforming, and the use of the millimeter wave spectrum (mmWave) work. This is not abstract theory — in practice, you will analyze signals and configurations.

2. 5G Core Architecture and Network Functions. Starting with Service-Based Architecture and interfaces N1-N16, ending with deploying Open5GS (a 3GPP implementation) in Docker. You will configure AMF, SMF, UPF, learn how registration, PDN session, and handover work.

3. Advanced Concepts: Open RAN (O-RAN), Network Slicing, MEC (Multi-access Edge Computing), SDN/NFV for telecom. All these are not just presentations, but configuration and testing using UERANSIM (UE and gNB emulator).

Specific skills you will gain:

• Ability to deploy and configure a test 5G network on your local computer using Docker containers.
• Understanding how end-to-end network slices are implemented for different service classes.
• Skills in analyzing NAS and NGAP messages from Open5GS and UERANSIM logs.
• Readiness for real-world tasks: from Open RAN integration to network capacity planning.

How Learning on asibiont.com Works: AI Personalization Without Marketing Hype

The asibiont.com platform uses its own AI engine to generate learning materials. This is not just "lectures" — the system analyzes your level at the start, your answers to questions, and your progress, and then adapts the content of each subsequent lesson.

How it works in practice:

1. Initial testing. You take a short entry survey: what is your experience in telecom? Are you familiar with Docker? Have you heard of O-RAN? The AI determines your starting point.

2. Lesson generation. For each topic (e.g., "Service-Based Architecture in 5G Core"), the neural network creates text that explains the material specifically for your level. If you are a beginner, there will be more analogies and connections to already familiar concepts (e.g., comparison with microservices in IT). If you are an experienced engineer, the focus will be on protocol details and configuration parameters.

3. Practical assignments. After each module, you receive a task: deploy a container with Open5GS, connect UERANSIM, check UE registration. All commands are in text format, no videos. This is convenient: you can copy commands, take notes, return to steps.

4. Explaining complex topics in simple language. The AI can rephrase material if you don't understand something. For example, if in a lesson on Network Slicing you didn't grasp the concept of SST (Slice/Service Type), the neural network will offer a simpler explanation with an analogy from the world of cloud computing.

5. 24/7 access. The entire course is text-based, so it's always in front of you. No fixed schedules — learn at your own pace.

Important: The AI tutor does not respond in real-time chat like a messenger. But the system is built so that you can request clarification on any block, and the neural network will generate an additional explanation. This is not a replacement for a live mentor, but an excellent tool for self-study.

Why AI Learning Is Modern and Effective for Telecom Engineers

Traditional online courses often suffer from "one size fits all": everyone watches the same recorded videos, reads the same slides. AI generation on asibiont.com solves several problems:

• Adaptability to pace. If you quickly mastered a topic, the AI will not hold you back with repetition. If something went wrong, the system will offer additional explanations.
• Relevance. Materials are generated based on the latest 3GPP specifications (Release 15-18). You won't encounter outdated descriptions like in textbooks from five years ago.
• Focus on practice. Instead of lectures on "how UPF works," you launch UPF in Docker and look at the logs. This approach gives an understanding that is impossible to obtain from theory alone.

For example, when studying O-RAN, you will not just read about CU/DU/RU splitting, but also be able to configure a Near-Real-Time RIC (RAN Intelligent Controller) in an emulated environment. This is a direct path to jobs with operators and vendors actively implementing Open RAN (e.g., Vodafone, Deutsche Telekom, Rakuten Mobile).

Who Is This Course For?

The course will be useful for:

• Network support and operations engineers — to understand new 5G functions and automate routine tasks.
• Solution architects — to design network slices and edge computing.
• Technical product managers — to understand the capabilities of 5G-Advanced and estimate deployment costs.

Experience in telecom is not required, but basic knowledge of Linux and TCP/IP will be helpful. If you are a developer looking to move into Telecom Cloud, this is also a good start.

Practical Example: Deploying Open5GS and UERANSIM on Your Laptop

One of the first practical blocks of the course is local emulation of a 5G network. Here's what it looks like (abbreviated example):

1. Install Docker and docker-compose on your computer.
2. Clone the repository with Open5GS and UERANSIM configurations.
3. Run docker-compose up -d — and within a few minutes you have AMF, SMF, UPF, and a base station emulator (gNB) running.
4. Connect a UE emulator (user device) — you see registration, PDU session setup.
5. Analyze logs: see the InitialUEMessage request, Identity Request/Response, Authentication Request/Response exchange.

You don't just read about signaling — you see it in real time. You can change parameters (e.g., TAI, PLMN) and observe how the network behavior changes.

It is precisely these tasks that allow you to move from abstract diagrams to a real understanding of how the 5G Core works.

Conclusion

The world of telecommunications is changing: software is replacing hardware monoliths, networks are becoming "programmable," and AI is beginning to manage radio resources. To remain a sought-after specialist, you need to understand not only legacy but also new paradigms — from Service-Based Architecture to O-RAN and Network Slicing.
