China First in the World to Approve 6G Trial Spectrum, Accelerating Commercial Deployment by 2030

World’s First 6G Trial Frequency Band Approved: China Opens a Generational Investment Window for Communications Infrastructure

The Ministry of Industry and Information Technology (MIIT) recently officially approved the use of the 6 GHz band (5925–6425 MHz) for 6G technology trials—making China the first country globally to issue a 6G trial frequency license. Though seemingly a technical administrative decision, this move represents a pivotal watershed in the evolution of the communications industry: it marks the formal transition of 6G R&D from purely theoretical modeling and simulation into system-level validation under real-world channel conditions. Unlike the incremental “standards-first, spectrum-later” approach adopted during early 5G development, this proactive allocation of the 6 GHz band reflects China’s strategic initiative to seize technological leadership. With 3GPP not yet having initiated formal 6G standard freeze (expected by end-2025) and ITU-R still finalizing the IMT-2030 vision framework, China has already established a full-stack trial infrastructure covering chip tape-outs, over-the-air (OTA) testing, and scenario-based integrated debugging. This milestone is not merely the starting point for transforming lab results into engineering reality—it is also a policy-driven, generation-scale investment mobilization explicitly geared toward commercial deployment before 2030.

Technical Rationale and Strategic Intent Behind the Spectrum Choice

The selection of the mid-band 6 GHz spectrum as the inaugural trial band is no coincidence. This band uniquely balances coverage capability and capacity potential: its propagation characteristics lie between those of Sub-6 GHz (the primary 5G band) and millimeter wave (above 24 GHz), offering relatively strong penetration while supporting up to 500 MHz of contiguous bandwidth—sufficient to meet core 6G targets, including a peak data rate of 1 Tbps, air-interface latency of 0.1 ms, and connection density exceeding 10 million devices per square kilometer. Crucially, the 6 GHz band is already designated as an “ideal band” for IMT applications by major global regulatory bodies—including the U.S. FCC and the European CEPT. By taking the lead in deploying it, China effectively secures agenda-setting authority on critical standardization issues such as spectrum compatibility and coexistence mechanisms. In contrast to the 5G era—when delayed spectrum allocation constrained base station deployment rhythms due to protracted international coordination—the “first-mover” adoption of 6 GHz will significantly shorten industrial validation cycles for frontier technologies, including terahertz communications, Reconfigurable Intelligent Surfaces (RIS), and Integrated Sensing and Communication (ISAC). According to calculations by the China Academy of Information and Communications Technology (CAICT), leveraging the 6 GHz trial platform could compress the iteration cycle for new RF front-end modules by 40%, and improve calibration efficiency for space–air–ground integrated network satellite–ground links by over threefold.

Accelerated Commercialization Timeline: Peak Capital Expenditure Shifts Forward to 2027–2029

Historical experience shows that the allocation of trial spectrum serves as the definitive trigger for capital expenditure (capex) initiation. Looking back at the 5G rollout: MIIT issued 5G trial licenses in 2018 → official commercial licenses followed in 2019 → equipment vendor order peaks occurred in 2020–2022 → and deep coverage and application expansion began in 2023. The 6G trajectory, however, is markedly accelerated: the recent 6 GHz approval coincided with the launch of tendering for Phase III projects under the “National 6G Technology R&D Promotion Working Group,” focusing specifically on terahertz chip prototypes, low-Earth-orbit (LEO) satellite 6G payloads, and AI-native air-interface protocol stacks. Modeling by CITIC Securities’ telecom research team forecasts that domestic 6G-related capex will exhibit a “front-loaded surge” pattern:

• 2025–2026: Intensive pre-research investments and chip tape-outs by equipment vendors (estimated average annual investment exceeding RMB 30 billion);
• 2027–2029: Concentrated procurement peaks for base station equipment, satellite payloads, and test instrumentation (CAGR reaching 35%), approximately two years earlier than the corresponding phase in the 5G cycle.

This acceleration stems from two key drivers: (1) continuous policy reinforcement under the “New Infrastructure” initiative—6G has been explicitly incorporated into the “14th Five-Year Plan for Digital Economy Development” as a special project; and (2) improved industrial maturity—Huawei HiSilicon and UNISOC have completed multiple multi-project wafer (MPW) tape-outs for 6 GHz RF SoCs, while ZTE, in collaboration with Galaxy Space, has entered the second phase of in-orbit verification for LEO satellite 6G payloads.

Industrial Chain Catalyst: Structured, Medium-Term Transmission from Equipment Vendors to AIoT Edge Computing

This policy breakthrough delivers structural and medium-term catalytic effects across the industrial chain.

• Communications Equipment Vendors: Directly benefit from trial network construction demand—ZTE and Huawei’s 6G prototype base stations have already entered joint debugging in operator laboratories.
• RF Front-End: Companies such as Maxscend and Wisol are accelerating mass production ramp-up of 6 GHz power amplifiers (PAs) and BAW/FBAR filters; domestic substitution rates are projected to rise from 35% in the 5G era to over 60%.
• Satellite Internet: As the core enabler of 6G’s “space–air–ground integrated” architecture, China Satellite Network Group (China SatNet) has launched tenders for its first batch of 6G satellite-mounted phased-array antennas—significantly enhancing order visibility for supporting firms including Chengchang Technology and Shanghai Hanxun.
• Most profoundly, AIoT Edge Computing: The “integrated communication–sensing–computation” architecture defined by 6G demands terminals capable of real-time environmental perception and local decision-making. AI chipmakers such as Cambricon and Horizon Robotics are deeply coupling their edge inference chips with 6G protocol stacks—ushering in a new paradigm where “the network itself becomes computing power.” Importantly, this round of catalysis differs fundamentally from past speculative hype: every beneficiary segment corresponds to clearly defined trial network milestones (e.g., deployment of the first 6 GHz field test system by Q3 2025), quantifiable technical targets (e.g., achieving 100 Gbps per-link throughput by 2026), and dedicated policy funding support (MIIT’s initial tranche of 6G special funds—RMB 1.28 billion—has already been disbursed).

A New Global Landscape of Competition and Cooperation: Technological Sovereignty Enters Uncharted Waters

China’s world-first 6G trial frequency allocation will also reshape the global technology governance landscape. Currently, the U.S., EU, Japan, and South Korea are all still at the stage of publishing 6G roadmaps (e.g., the U.S. Next G Alliance prioritizes terahertz, while the EU’s Hexa-X-II emphasizes AI-native networks), but none has yet granted formal spectrum authorization. China’s pioneering step may either accelerate ITU-R’s coordination of the IMT-2030 spectrum framework—or heighten risks of fragmentation and “camp formation” in technical standards. Particularly on critical issues like integration rules for satellite internet and terrestrial networks, and AI-driven dynamic spectrum sharing mechanisms, empirical trial data will constitute foundational leverage for influence. Notably, the MIIT approval explicitly mandates that “trial results must be openly shared with ITU-R and 3GPP,” underscoring China’s pragmatic stance in global governance. Yet geopolitical complexities cannot be ignored: recent intensified scrutiny of communications supply chains across multiple countries—including the U.S. updating its Entity List to add export controls on semiconductor test equipment—is compelling China to accelerate development of an independently controllable 6G validation ecosystem. This requires the industrial chain to simultaneously pursue international collaboration and build a comprehensive, secure foundation spanning EDA tools, advanced packaging, and test instrumentation.

The approval of the 6G trial frequency band is far more than just a radio-frequency usage license. It is the starting pistol for a generational upgrade of communications infrastructure; it is a new racetrack in the contest for technological sovereignty; and it is a stress test for China’s manufacturing sector as it strives to ascend to the apex of the global value chain. When 6 GHz radio waves begin propagating across Chinese soil for the first time, they carry not only terabyte-per-second data streams—but also a nation’s strategic resolve and engineering ambition in shaping the evolution of digital civilization.
