MWC Shanghai observations: 6G and satellite internet enter the scale-up cost-cutting phase

MWC Shanghai 2026 opened as scheduled. Unlike last year's heated atmosphere, when 5G-A commercial orders landed densely, this year's halls were more pragmatic — focused on when technology can turn into real money. The newly independent "6G Industry Ecosystem Zone" and the "Future Constellation" satellite section drew strong crowds, but industry discussion centered on the path and trade-offs required to turn vision into something that can actually be realized.

In the 6G direction, three paths — integrated sensing and communication, AI-native, and space-air-ground integration — are already undisputed; chipmakers have even started pre-research and inventory preparation early. In the satellite internet field, the "land-grab war" for orbital frequency resources is basically over, and scale deployment plus cost reduction have become the new theme. Meanwhile, terminal vendors and investment institutions are largely waiting: terminals are waiting for killer applications, while investors can't figure out the payback cycle; even international satellite players that are already profitable still feel the strain in early civil-market cultivation.

With the financial bill from 5G investment not yet fully settled, 6G and satellite internet are now jointly entering a transitional period of "clear vision, hard monetization." The technical route is getting narrower and narrower, but the commercial path is getting wider and wider. Under real investment-return constraints, the industry needs more pragmatic answers than grand narratives.

6G technical routes converge, but the commercial loop is still being explored

Walking into the 6G industry ecosystem area in Hall N3 at MWC Shanghai, the five major sections — Beijing 6G Lab overall zone, communication enhancement, integrated sensing and communication, integrated communication-computing-intelligence, and space-air-ground integration — make the core 6G vision much clearer. For the first time in MWC Shanghai history, an entire hall was dedicated to 6G, sending a clear industry signal: 6G has moved from conceptual discussion into a critical stage of system validation.

"If last year people were still arguing over what 6G should do, this year the argument is about how to do it and what trade-offs to make," said a technician at the Beijing 6G Lab overall zone. At present, the three enhancement paths — integrated sensing and communication, AI-native, and space-air-ground integration — have basically formed an industry consensus, while key technologies such as terahertz communication and intelligent metasurfaces have entered prototype verification.

Upstream deployment is accelerating. Qualcomm showcased an end-to-end 6G prototype system; Galaxy Space publicly displayed for the first time its self-developed second-generation phone-direct-connect phased-array antenna in the 6G ecosystem zone; vivo presented its 6G pre-research prototype and technical roadmap. Unlike Xiaomi, which focuses on underlying transmission algorithms, and OPPO, which focuses on communication paradigm innovation, vivo's direction leans more toward end-to-end systems and application landing: its full 6G trial system covers MR terminals, 6G terminal prototypes (UE), 6G base stations (RAN), and core network links.

The head of a domestic chipmaker's on-site team said the company's internal 6G pre-research team has doubled versus last year, because "if we wait until standards are frozen to start, it's already too late; we must build the technical reserves ahead of time."

However, terminal vendors are relatively cautious. When Blue Whale Technology reporters asked several phone brands about 6G terminal plans in the 6G zone, most replied that they are "closely watching," and there were few consumer-product demos aimed at 6G on the booths. A 6G pre-research director at a global top-five smartphone maker said he could not yet provide a clear 6G phone commercialization roadmap, not because of technical limits, but because the path from terminal-side user demand to application scenarios is still under evaluation. He believes the experience dividend of 5G has not yet been fully released, and 6G's envisioned immersive holographic and multi-sensory scenes are still some distance away from mass consumption.

Investors are also cautious. After watching several 6G demos, an early-stage investor said the technology trajectory is impressive, but from an investment standpoint the capital returns from 5G are still being digested, and the future R&D and network-deployment investment for 6G will be huge. The exit cycle and return expectations lack enough data support. He admitted that for now he is mainly staying in tracking mode, waiting for a clearer commercial signal before making a move.

"Future constellation": the pattern is taking shape, but the profitability path still needs validation

Unlike the 6G zone, which emphasizes key technology validation, the first-time "Future Constellation" satellite industry zone presents a different rhythm: orbital patterns are taking shape, and participants are entering a stage of refined resource and cost management.

Operators of domestic low-orbit broadband and narrowband constellations such as Geespace, China Electric Power Science and Technology, and Galaxy Space built booths alongside international players like Iridium. Geespace showcased real low-orbit satellite internet terminal devices for scenarios such as ocean-going vessels and desert mining areas; China Electric Power Science and Technology promoted Tianqi constellation use cases in IoT; and Galaxy Space engineers played a live video-call test based on the Qianfan constellation.

On site, a representative from China Electric Power Science and Technology said that the scramble for orbital and frequency resources in satellite internet is largely over, and the key now is large-scale deployment and cost control. He revealed that the mass-production cost of the company's narrowband communication payloads continues to fall, but also noted that user scale for satellite internet services has not yet reached breakeven, so at least in the next few years government and industry orders will remain the basic foundation of revenue.

In the process of forming a profitability model, terminal cost is a major focus. Antenna and module vendors generally said in discussions that costs are falling quickly and the products are already capable of being integrated into mainstream handset designs, but most vendors did not disclose specific numbers.

The business manager at Iridium's booth said Iridium has achieved positive cash flow thanks to narrowband voice and low-speed data services, but the traditional market is nearing saturation. The next growth phase needs to expand into IoT and emergency communications. Domestic low-orbit broadband constellations are still in the stage of scaling up first, and reaching breakeven will require time and user accumulation.
