The 2026 Mobile World Congress in Barcelona framed the next decade of telecom as “The IQ Era,” but the conversations on the floor were dominated by an even more prosaic subject: timing. A clearer 6G timetable emerged, with 3GPP’s R21 expected to be finalised in June 2026, industry roadmaps pointing to pre‑commercial 6G handsets in 2028 and broad commercial rollouts aimed at 2029 when standards are anticipated to freeze.
What separates 6G from a mere speed upgrade is its ambition to expand the reach of connectivity itself. Presentations and prototypes at MWC sketched a multi‑layered network that stitches together terrestrial base stations, high‑altitude platforms, constellations of low‑, medium‑ and high‑earth‑orbit satellites, and maritime nodes into a single “space–air–ground–sea” fabric. That architecture promises ubiquitous coverage and new functions — from pervasive sensing to network‑level intelligence — that go beyond sending data faster.
Chinese equipment makers, led by Huawei and ZTE, used the stage to convert concepts into prototypes and spectrum claims. Huawei showcased a U6GHz product family and a 256T AAU that it says combines 1,000+ antenna elements to push single‑user peak rates into the multi‑gigabit (ten‑gigabit) range while supporting what the company describes as tens of terabits of capacity per cell. U6GHz (6425–7125MHz) is presented as a strategically valuable sub‑6GHz block: wide contiguous bandwidth that balances coverage and capacity and offers operators a smoother path from 5G‑Advanced to 6G.
ZTE countered with a 2,000+ antenna‑element U6GHz prototype claiming a tenfold capacity increase versus 5G‑A when paired with AI algorithms. Huawei also publicised developments in terahertz chips, AI energy‑saving base stations and a “starry sky” architecture for satellite integration; its published 6G patent share was cited at roughly 15.7% globally. The message was clear: Chinese vendors are fighting to lock in spectrum, standards influence and early deployments.
Chipmakers and western vendors emphasised systems and use cases rather than just radio hardware. Qualcomm outlined an endpoint‑driven strategy that embeds AI on smartphones, PCs, cars, wearables and XR devices, arguing that 6G will be a platform for scaling AI across the economy. Qualcomm expects 6G pre‑commercial terminals in 2028 and stressed that 6G innovation will span end devices, RAN, edge servers and data centres — creating opportunities in connectivity, wide‑area sensing and distributed network compute.
Ericsson’s demos focused on integrated sensing and communications (ISAC) and real‑time orchestration: networks that can detect a fallen person, upload context to a command centre and trigger an automated dispatch that routes drones or ambulances along optimised corridors. The firm stressed ecosystem work — testing interoperability with MediaTek, Qualcomm and even Apple on multi‑radio spectrum sharing — to enable smooth migration paths and cost‑efficient deployments from 5G to 6G.
The timetable and commercial expectations on show at MWC matter for operators making multi‑billion‑dollar investment decisions now. U6GHz is being pitched as a pragmatic, harmonisable band that protects past 5G investments while unlocking new capacity; several countries, including China and the UAE, have already announced allocations. That creates a two‑track dynamic: operators can upgrade towards “5G‑Advanced” with an eye on 6G, while vendors race to populate the value chain — chips, RAN, satellites, software and services — that will define vendor lock‑in and national technological influence.
This sprint exposes risks as well as opportunities. Spectrum harmonisation, cross‑border satellite coordination, energy and compute demands, and the geopolitics of supply chains and patents could fragment the market. Standardisation choices and intellectual‑property stakes will influence who captures the high‑margin services around sensing, digital twins and industrial automation. For consumers and enterprises, practical benefits may take years to materialise, but the groundwork being laid at MWC 2026 suggests the form of a future in which networks perform sensing, compute and orchestration as native functions rather than add‑ons.
