The Facts: What Was MWC 2026?
MWC (Mobile World Congress) 2026 is the world's largest ICT exhibition, hosted by the GSMA. Alongside CES in the U.S. and IFA in Germany, it is one of the world's top three ICT expos. This year it was held from March 2–5 at Fira Gran Via in Barcelona, Spain.
The theme was "The IQ Era." It was organized around six exhibition tracks: Intelligent Infrastructure, Enterprise AI, Connected AI, Tech4All, Game Changers, and Spatial Computing.
"In the past, MWC was a venue for new smartphone unveilings. But in the AI era, it has firmly established itself as the stage where AI-driven network innovation is showcased." — Unicorn Factory
The Growth Drivers: Why Is MWC Surging Again?
1. Samsung Electronics — Planting the Flag for Agentic AI
Samsung unveiled a massive booth spanning 1,745㎡ divided into 9 zones. At the entrance, visitors were greeted by an art installation called 'RE:Birth Crystals' (by artist Park Sun-ki), made from quartz fragments discarded during semiconductor manufacturing.
The centerpiece displays were the Galaxy S26 series and the Galaxy AI ecosystem. Beyond mere smartphones, Samsung presented its vision of "Agentic AI" — where AI understands context and acts autonomously on behalf of users. Its network division and Samsung Display also operated separate exhibition halls, expanding its B2B market offensive.
2. SK Telecom — Full-Stack AI Portfolio
From a 992㎡ booth, SKT announced its "AI for Infinite Possibilities" strategy, covering infrastructure, models, and services. The key features were technology that embeds AI directly into network operations management systems and enterprise solutions supporting digital transformation.
3. LG Uplus — Physical AI and Humanoids
CEO Hong Bum-sik took the keynote stage personally to unveil the "Humanizing Every Connection" vision. The concept of Physical AI — combining its proprietary AI call agent ixi-O with humanoid robotics — generated significant buzz.
4. KT — Human-Centered AI
KT set up an independent exhibition hall in Hall 4, presenting AI solutions at the network infrastructure level alongside a human-centered AI service strategy.
5. K-water's Surprise Debut
K-water (Korea Water Resources Corporation) attended MWC for the first time, showcasing AI-based water purification plant automation, the dam operations digital twin 'Digital Garam+', and a smart water supply network management system. Technology cooperation meetings with Google and Meta were also held.
Context and Background: From Smartphone Show to AI Platform Arena
In the early 2010s smartphone boom, MWC was the launchpad for Samsung, Apple, and Sony's new devices. But with smartphone market maturation + the generative AI explosion, its character has fundamentally changed.
- MWC 2024: Competition for AI-enabled smartphones
- MWC 2025: On-device AI + 6G roadmap reveals
- MWC 2026: Expansion into AI infrastructure, agentic AI, and physical AI (robotics)
Notably, China's Xiaomi unveiled an EV concept design, signaling that mobile companies are now crossing over into mobility.
Outlook: K-AI's Global Competitiveness
In terms of number of participating companies, Korea ranked 4th globally after Spain, the U.S., and China. It was the first time Korea's three major telecoms each independently presented their own AI strategies on the global stage simultaneously.
However, challenges remain. The surge in energy costs from the Middle East war and the KOSPI -12% shock are direct pressure factors on domestic ICT companies' capital expenditure (CapEx) plans. Before the AI vision presented at MWC translates into actual revenue, key hurdles remain: the commercialization of 6G (expected around 2030) and establishing viable AI monetization models.
