In-depth articles, research and technology experiments
The mission of TechLab
TechLab is for readers who want to understand how technology actually works, beyond product announcements and surface-level explanations. We examine systems, test tools and connect technical details with their real-world consequences.
It brings together in-depth educational articles, original laboratory work and clearly identified opinion. The aim is not to tell you what to think, but to give you enough context to reach your own conclusions.
What we explore
- Radio, spectrum and modern communications
- Local artificial intelligence and autonomous systems
- Digital privacy, surveillance and data leaks
- Public infrastructure, networks and critical systems
- Security, encryption and emerging technologies
- Experiments with SDR, hardware and applied electronics
