From 6G to quantum computing and AI: How a 1950s invention shapes tech giants of today and tomorrow
Ever wondered what makes your smartphone, satellite, or self-driving car function flawlessly? Meet an unsung hero behind it all: the Vector Network Analyzer (VNA). This 75-year-old technology was invented by Rohde & Schwarz pioneers and is an invisible enabler of RF engineering. In this episode, we unravel its journey from analog labs to AI-driven precision, and why it’s more vital now than ever.
