2026: The Year 6G Moves from Theory to Engineering Challenge
Although commercial 6G network deployments are planned for 2030, 2026 is a critical moment for the Research & Development (R&D) sector. Right now, in laboratories in Krakow, Wroclaw, or Warsaw, the foundations for 3GPP Release 19 and 20 standards are being created, which will define the 6G architecture. For systems engineers, this means transitioning from optimizing existing 5G solutions to designing an entirely new reality: from ubiquitous intelligence (AI-Native) to the integration of communication with sensing (ISAC).
1. AI-Native RAN: Artificial Intelligence in the Physical Layer
In 6G, artificial intelligence is not an add-on – it is an integral part of the architecture. An R&D engineer in 2026 must be proficient in Deep Learning applied to the physical layer (PHY). Key competencies include:
- Designing neural networks to replace traditional signal processing blocks (e.g., channel estimation or decoding).
- Knowledge of frameworks such as PyTorch or TensorFlow in the context of radio optimization.
- Ability to implement TinyML algorithms on resource-constrained edge devices.
2. Exploration of Sub-THz and Terahertz Bands
6G aims for speeds of around 1 Tbps, which requires moving beyond millimeter-wave bands. Systems engineers must tackle propagation challenges in bands above 100 GHz. Highly valued skills include:
- Advanced radio channel modeling for extremely high frequencies.
- Next-generation Massive MIMO technology and high-precision Beamforming.
- Design of integrated circuits (RFIC) capable of operating in sub-THz bands.
3. ISAC and RIS: A Network That Sees and Feels
One of the most revolutionary aspects of 6G is Integrated Sensing and Communication (ISAC). The network is to function as a radar, allowing for object localization with centimeter precision without the use of GPS. Equally important are Reconfigurable Intelligent Surfaces (RIS) – smart mirrors that control the reflection of radio waves. A candidate for the R&D elite should understand the physics of these solutions and real-time signal phase control algorithms.
4. Cloud-Native and Programmability (O-RAN 2.0)
The era of monolithic base stations has come to an end. In 2026, full virtualization of network functions is the standard. A systems engineer is required to have:
- Proficiency in microservices architecture and orchestration (Kubernetes, Docker).
- Knowledge of Open RAN standards, which enable interoperability between vendors.
- Programming skills in languages C++ (for time-critical components) and Python (for automation and data analysis).
Where is 6G Being Built in Poland?
Poland is one of the most important telecommunications R&D hubs in Central Europe. Global players such as Nokia, Ericsson, Samsung, and the domestic Comarch are intensively recruiting specialists for their research centers. Engineers in Poland work on algorithms that will become the global standard in a few years. Working in these centers provides not only prestige but, above all, access to unique measurement equipment and a real impact on shaping the digital future.
How to Prepare for Recruitment?
The entry threshold for 6G R&D is high, but the development path is clear. In addition to a solid degree in a relevant field (Telecommunications, Electronics, Computer Science), a project portfolio or participation in scientific publications regarding the next generation of networks is key.
