Asia-Pacific 5G Infrastructure Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Asia-Pacific 5G Infrastructure Market Trends and Insights

Rising 5G Traffic Density and Low-Latency Demand

China had more than 1.204 billion 5G subscriptions and 2.888 billion mobile IoT terminal connections by the end of 2025. This scale requires operators to add capacity while also upgrading their standalone core networks. China’s 5G-Advanced service covered 330 cities in March 2026, supported by active antenna systems that can manage beamforming at scale. The parallel buildout of dense radio sites and standalone architecture shortens the path to low-latency services, but it also increases early capital requirements for vendors and site specialists. Smart factories using 5G and industrial internet programs recorded 20.5% gains in product quality and 24.7% gains in production capacity. These operating results support wider demand for capacity and latency-sensitive industrial connectivity in the Asia-Pacific 5G infrastructure market.

Government-Led Spectrum Allocation and Rollout Programs

India’s Telecom Regulatory Authority released auction recommendations in February 2026 for 11,789.15MHz across 9 frequency bands. The proposal carried a reserve value of INR 2.10 lakh crore (USD 23.1 billion).^{[1]Telecom Regulatory Authority of India, “Recommendations on the Auction of Radio Frequency Spectrum in the Frequency Bands Identified for International Mobile Telecommunications,” Telecom Regulatory Authority of India, trai.gov.in} It also linked a 10% reduction in the reserve price to new base stations in coverage gaps, directing operator spending toward underserved areas. Vietnam paired spectrum discounts with equipment-cost support for operators that build 20,000 5G base stations, using policy to encourage infrastructure investment. South Korea required standalone upgrades by 2026 and used lower LTE reallocation fees to support operators that meet indoor coverage goals. Government measures now extend beyond spectrum allocation and shape the pace, location, and architecture of network investment across the Asia-Pacific 5G infrastructure market.

Expansion of Private 5G for Industrial Automation

ZTE Corporation and Telkomsel deployed a UE-transparent Hybrid Private Network at an automotive facility in Karawang, Indonesia, in November 2025.^{[2]ZTE Corporation, “ZTE Collaborates with Telkomsel to Build a UE-Transparent Hybrid Private Network,” ZTE OpenLab, zte.com.cn} The design provided industrial-grade 5G without hardware changes to existing factory devices. This approach can reduce compatibility costs that have limited private 5G adoption in ASEAN factories. China had more than 25,000 5G and industrial internet projects and 1,260 specialized 5G factories active in the first quarter of 2026. The reported 18.4% reduction in operating costs and 24.7% increase in production capacity at benchmark facilities give manufacturers practical evidence for private-network investment. Industrial automation, therefore, gives the Asia-Pacific 5G infrastructure market a demand base that public consumer coverage alone cannot provide.

Accelerating Open RAN and Cloud-Native Network Adoption

NTT DOCOMO and NEC launched Japan’s first commercial 5G Core on Amazon Web Services on February 26, 2026.^{[3]NTT DOCOMO, “DOCOMO and NEC Launch Japan’s First Commercial 5G Core on AWS, Built with World’s First AI-Automated Network Construction Technology,” NTT DOCOMO, docomo.ne.jp} The companies stated that AI automation reduced deployment time by 80%, enabling cloud-native core infrastructure to move from trials into carrier operations. Rakuten Symphony received a Japanese Ministry of Economy, Trade and Industry grant of up to JPY 8 billion (USD 50.2 million) in April 2026 for Open RAN and RAN Intelligent Controller deployments in 7 countries.^{[4]Rakuten Symphony, “Rakuten Symphony Selected for METI Grant to Accelerate Open RAN and RIC Deployment in the Global South,” Rakuten Symphony, rakuten.com} The program combines deployment activity with interoperability testing and helps diversify radio supply chains. Nokia’s cloud-native IMS and subscriber data management functions also went live on Rakuten Mobile’s network in March 2026. These production systems indicate that the Asia-Pacific 5G infrastructure market is moving toward multi-vendor core and radio environments.

High Densification and Fiber Backhaul CAPEX

Dense small-cell networks require fiber links to each site, especially where operators use mmWave spectrum or add capacity layers. China’s optical fiber network reached 74.99 million km by the end of 2025, providing a strong foundation for its large 5G rollout. Many Southeast Asian and South Asian markets have less last-mile fiber, which makes densification more expensive and slower to deliver. The wider region faced a USD 200 billion infrastructure investment shortfall through the end of the decade, including gaps in backhaul financing. Operators without strong fiber networks must choose between expensive wireless backhaul and delayed capacity expansion. Site acquisition, power access, and landlord negotiations can add 18-24 months to small-cell rollouts in markets such as India and Indonesia.

Spectrum Cost Pressure and Uneven Mid-Band Availability

Mid-band spectrum from 1-6GHz supports most 5G deployments in the region, with 3.5GHz operating as the main workhorse band. Indonesia’s planned 3.5GHz award remained delayed until 2027 in March 2025, limiting the country’s access to new mid-band capacity. High reserve prices can redirect operator capital from network construction toward auction payments. India’s 2026 recommendations proposed reductions of 7-37% across relevant bands, showing how price reforms can change the investment balance. The effect is particularly significant for new entrants and second-network operators that must compete with providers holding earlier spectrum awards. Uneven band availability may therefore result in varying coverage quality and rollout schedules across the Asia-Pacific 5G infrastructure market.

Segment Analysis

By Communication Infrastructure: RAN Investment Anchors the Deployment Cycle

5G Radio Access Network held 60.96% of the Asia-Pacific 5G infrastructure market share within communication infrastructure in 2025. RAN remains the main destination for capital spending as operators densify base stations across China, India, Japan, and Southeast Asia. China Tower deployed more than 900,000 base stations per year by mid-2026 and had helped build more than 5.6 million sites in total. This operating scale shows why radio equipment, antennas, and site infrastructure continue to account for a large part of spending. Transport/xHaul is the second-largest sub-segment because every new macro site and small cell requires fronthaul, midhaul, or backhaul links.

Core Network is projected to expand at a 14.80% CAGR through 2031, making it the fastest-growing sub-segment of communication infrastructure. The Asia-Pacific 5G infrastructure market size for cloud-native core systems is supported by the shift away from legacy packet gateways. NTT DOCOMO’s commercial cloud-native core reduced power consumption by 70%, according to the company, offering an operating-cost benchmark for other operators. Nokia and Tune Talk completed an ASEAN cloud-native core deployment in January 2026, extending this architecture to a developing operator market. Cloud-native core platforms can help operators scale capacity, automate network functions, and support enterprise services. Open Telecom Ecosystem practices and 3GPP Release 17 and Release 18 requirements are also affecting vendor selection for these deployments.

By Spectrum Band: Mid-Band Dominance Faces Targeted mmWave Demand

Mid-band spectrum held 69.21% share of the spectrum band segment in 2025. It remains the primary coverage and capacity layer for macro 5G networks because regional regulators have broadly adopted plans for the 3.5 GHz band. The band offers a practical balance between propagation range and network capacity. Low-band spectrum below 1 GHz supports rural coverage and indoor service in countries with extensive underserved areas. India and Australia give policy priority to the 600 MHz and 700 MHz bands because those frequencies can extend coverage beyond major cities.

High-band/mmWave is projected to expand at a 17.22% CAGR through 2031. Japan’s operators have commercial 28GHz deployments, while South Korea has enterprise licensing for 28GHz use. India also included 26GHz in its forthcoming spectrum auction framework. The Asia-Pacific 5G infrastructure market is likely to use mmWave first in factories, stadiums, transit facilities, and similar concentrated locations rather than broad consumer coverage. Samsung’s live trial with KDDI showed a 52% increase in throughput on the 3.7GHz band using its AI-powered RAN Speed Optimizer. Equipment costs can improve as Japan and South Korea build more operational experience, which could support use in other regional markets after 2027.

By Network Architecture: NSA Remains Large As SA Adoption Accelerates

Non-Standalone architecture held 66.30% of the network architecture segment in 2025. NSA uses a 4G LTE anchor with a 5G New Radio overlay, which allowed many operators to introduce 5G on their existing core networks. This approach offered better consumer download speeds at a lower incremental cost. Its installed base remains important across much of the region. Operators continue to rely on NSA, where the business case for a dedicated 5G core is not yet established.

Standalone architecture is projected to expand at a 15.55% CAGR through 2031. The need for network slicing, low-latency services, and enterprise-focused revenue models is driving the Asia-Pacific 5G infrastructure market for SA deployments. South Korea required operators to upgrade to 5G SA by 2026 and used LTE reallocation fee incentives linked to indoor base-station goals. KT launched South Korea’s first 5G SA service for iPhone users in March 2026, while SK Telecom targeted a commercial SA launch in the fourth quarter of 2026. SA migration aligns products with 3GPP Release 16 and later standards, reducing the integration risk that previously slowed dedicated 5G core adoption.

By Core Network Technology: NFV Retains Scale While Network Slicing Builds Demand

Network Function Virtualization held 35.12% share of the core network technology segment in 2025. It represents the installed base created when operators moved functions from dedicated hardware to virtualized systems. Software-Defined Networking supports traffic control across these systems. Multi-Access Edge Computing provides local processing capacity for workloads that need faster response times. Ports, logistics facilities, and manufacturing sites are among the settings where edge computing can support private 5G services.

Network slicing is projected to expand at a 17.48% CAGR through 2031. The Asia-Pacific 5G infrastructure market share for network slicing reflects a shift from standard data plans to service tiers tailored to specific use cases. Asia-Pacific accounted for 36% of commercial network slicing offerings worldwide in November 2025. Jio Platforms launched 10 active nationwide 5G slices in August 2025 for IoT, gaming, fixed wireless access, and mission-critical communications. Bharti Airtel launched commercial 5G network slicing in India in 2026, using Ericsson technology and Nokia’s 5G Core capabilities, enabling operators to offer service characteristics that conventional consumer connectivity cannot provide.

By End-User Vertical: Consumer Electronics Leads While Manufacturing Expands

Consumer electronics accounted for 42.00% of the end-user vertical segment in 2025. Smartphone adoption across China, South Korea, Japan, India, and Southeast Asia continues to drive demand for broad macro-layer coverage. This demand supports investment in the radio networks that later serve enterprise use cases. Automotive and mobility, healthcare and life sciences, energy and utilities, public safety and defense, and smart cities require more specialized connectivity. Their needs include stronger device density, low latency, service separation, and predictable performance.

Industrial manufacturing is projected to expand at a 16.50% CAGR through 2031. The Telkomsel-Pegatron Smart Manufacturing Lighthouse in Batam achieved latency below 10ms and planned to increase the number of connected devices from 600 to more than 1,200. Nokia and Indosat agreed in June 2026 to a nationwide AI-RAN rollout in Indonesia, supported by NVIDIA’s USD 1 billion investment in Nokia. These projects show that industrial users are seeking automated operations, local computing, and secure connections between machines and control systems from the Asia-Pacific 5G infrastructure market. The IEC 62443 standard is also becoming more relevant as private 5G operators establish cybersecurity practices for operational technology networks.

Geography Analysis

China held 51.20% of the Asia-Pacific 5G infrastructure market share in 2025. The country had 4.958 million active 5G base stations in March 2026, equal to 34.4 sites per 10,000 people. 5G coverage had reached all towns and more than 95% of administrative villages. Co-build and co-share programs involving China Mobile, China Unicom, and China Telecom supported this broad deployment. China projected a 5G contribution of CNY 5.6 trillion (USD 767 billion) to national economic output and planned to deploy 500,000 additional 5G-Advanced base stations and 1 million high-speed optical ports under its 15th Five-Year Plan. 

India is projected to expand at a 17.20% CAGR through 2031, the fastest rate among the national markets cited. More than 518,000 5G base transceiver stations had been installed by 2025, supporting around 380 million wireless data subscribers on 5G services. The proposed reduction in auction reserve prices and incentives for coverage-deficient areas supports the growth of the Asia-Pacific 5G infrastructure market in India. India’s National Frequency Allocation Plan 2025 identified approximately 700 MHz in the 6 GHz band for future 5G, 5G-Advanced, and 6G use. 

Japan and South Korea form the region’s technology leadership corridor for standalone networks and early AI-RAN work. South Korea’s government-required SA upgrades, KT’s March 2026 iPhone service, and SK Telecom’s planned fourth-quarter 2026 launch support a near-term architecture shift. Japan’s NTT DOCOMO, SoftBank, KDDI, and Rakuten Mobile operate commercial or near-commercial SA networks, while Ericsson and SoftBank signed a multiyear framework in March 2026 to modernize SoftBank’s core toward standalone operation. Australia also has a programmable 5G-Advanced initiative with Ericsson and Telstra that includes Open RAN-ready radio hardware and AI-based automation. Southeast Asia and Taiwan offer varied entry points, including Vietnam’s spectrum measures, Indonesia’s private 5G manufacturing projects, and Taiwan’s AI-native network work.
