Japan’s National Institute of Information and Communications Technology, better known as National Institute of Information and Communications Technology, is bringing a very deliberate message to Mobile World Congress Barcelona 2026 this March: the future of mobile networks is no longer just faster radio links, but a fully AI-native communications fabric designed for what comes after 5G. From March 2 to 5, inside Hall 6 at Stand F54, NICT’s booth is less about static panels and more about proof-in-motion, with live systems running, blinking, translating, transmitting, and, in some cases, thinking on their own. You can almost feel the shift in emphasis walking past — fewer buzzwords, more physics, more code, more real-world constraints being tackled head-on.
The centerpiece is terahertz-band wireless transmission, demonstrated live rather than promised on slides. Terahertz sits in that uneasy zone between theory and deployment, and NICT leans into that tension, showing ultra-high-speed data transfer that hints at what Beyond 5G and early 6G architectures might actually look like when pushed into dense, urban, European-style environments. Alongside it, AI-driven ultra-spot communications take aim at one of today’s quiet network frustrations: delivering extreme performance exactly where it’s needed, for milliseconds or minutes, without overbuilding everything else. It’s a subtle idea, but standing there watching the system adapt in real time, it clicks — this is less about blanket coverage and more about intelligent precision.
Then there’s the human layer, where things get oddly futuristic and oddly practical at the same time. NICT is demonstrating cybernetic avatar teleoperation that feels less like a lab trick and more like an early draft of remote presence for hazardous work, healthcare, or cross-border collaboration. Nearby, real-time multilingual communication runs continuously, translating speech across languages with a naturalness that makes you forget how computationally heavy that process actually is. In the background, advanced security technologies quietly monitor, detect, and respond, including live cyberattack visualization and quantum-based secure communications that underline a simple truth: higher capacity without trust is just a bigger problem at higher speed.
What ties all of this together is NICT’s internal structure, built around three pillars that feel unusually coherent for a public research organization. CONNECT focuses on Beyond 5G and 6G infrastructure as a tool for digital inclusion rather than just peak throughput. EXPAND is about augmenting human capability through AI and advanced communications, not replacing it, which shows in the demos. SECURE grounds everything in resilience, from real-time cybersecurity monitoring to quantum technologies that assume hostile conditions as the default, not the exception. It’s a worldview that feels shaped by earthquakes, supply-chain shocks, and cyber conflict — and that perspective travels well to Europe.
By showing up at MWC Barcelona 2026 with working systems instead of future tense language, NICT is clearly signaling its intent to collaborate, not just to impress. The booth feels like an open invitation to European operators, vendors, researchers, and policymakers to test assumptions together, argue over architectures, and maybe sketch out a shared path toward a more connected, secure, and genuinely intelligent digital society. You leave with the sense that Beyond 5G isn’t a marketing phase label anymore — it’s already being built, quietly, at Stand F54.
