What's Next in Wireless Communication? An Insider's Perspective

Joaquin Torrecilla began his engineering career programming a Sinclair Spectrum in Basic and Assembler. He later tested some of the industry's very first commercial Bluetooth solutions. Today, he remains at the forefront of RF and protocol testing. In this episode, Joaquin shares key insights from his 20 years with the 3GPP RAN Plenary. He also discusses the complex balance required to create and certify global wireless testing standards. The conversation dives deep into the game-changing capabilities of 5G Advanced. Joaquin breaks down the impact of: Network Slicing: Customizing virtual channels for specific industry needs. Time-Sensitive Networking (TSN): Keeping strict synchronization across wired and wireless systems. Non-Terrestrial Networks (NTNs): Connecting standard devices directly to space. Joaquin explains how fast-moving low Earth orbit (LEO) satellites manage continuous handovers overhead. We also learn how these satellites use high-precision laser links to talk to each other in orbit. Finally, he explains RedCap (Reduced Capacity) 5G. This technology acts as a cost-optimized, low-power bridge for smartwatches and IoT devices. Looking to the future, Joaquin discusses the early stages of 6G. This next generation of wireless will be AI-native from day one. Its architecture will automatically optimize network layers and manage massive amounts of test data. Joaquin now leads software transformation at Keysight. This background allows him to highlight how modern networks are moving away from proprietary hardware boxes and shifting to virtualized software stacks. To wrap up, Joaquin offers great advice for younger engineers. He explains why the test and measurement industry provides unmatched, system-level knowledge.
