Asia-Pacific Industrial Communication Market Trends and Insights

Growing Adoption of Industry 4.0-Driven Automation

Manufacturers across the region lifted smart-technology capital allocations to a range of 11%–15% in 2024, a step-change from sub-5% pre-pandemic levels. Investments extend beyond programmable logic controllers to digital twins and predictive-maintenance platforms, all of which require deterministic multi-protocol backbones. An Industry 4.0 pilot factory in the Philippines, funded by Siemens and Union Bank, showcases interoperability between legacy Modbus devices and next-generation OPC UA servers and lowers adoption barriers for small manufacturers. Such regional demonstrators are accelerating proof-of-value cycles and spurring follow-on orders for converged networks.

Expansion of 5G and Private-LTE Industrial Campuses

Private 5G deployments have transitioned from trials to production, replacing legacy Wi-Fi in electromagnetically noisy environments and supporting mobile robots that require seamless, microsecond-class handovers. Cisco, Mitsui, and KDDI opened a dedicated 5G laboratory in Japan to validate ultra-reliable low-latency applications for automotive assembly and pharmaceutical cleanrooms.^{[2]Rockwell Automation, “The State of Smart Manufacturing Report,” rockwellautomation.com} Japan’s communications ministry reported 23,363 millimeter-wave base stations online in 2024, with a target of 50,000 by 2027, laying the groundwork for pervasive industrial IoT. Licensed spectrum and deterministic quality-of-service policies make private-LTE particularly attractive for mission-critical control.

Proliferation of IIoT Edge Devices Demanding Low-Latency Links

The installed base of wireless field devices is doubling roughly every four years as plants replace 4–20 mA loops in hazardous or mobile equipment. Emerson, for example, surpassed 10 million WirelessHART pressure-transmitter shipments, many of which serve offshore platforms where cable runs are uneconomical.^{[3]Emerson, “WirelessHART installations milestone,” emerson.com} Predictive-maintenance algorithms running at the edge now require sensor refreshes every 50 milliseconds, deterministic wireless options, combining ISA100 and Wi-Fi 6, lower latency, and reduce the bill of materials, thereby accelerating adoption.

Government-Backed Smart-Manufacturing Initiatives

India’s fiscal-2024 budget earmarked INR 11.11 trillion (USD 132.3 billion) toward infrastructure, including dedicated allocations for semiconductor fabs and electric-vehicle supply chains that rely on cleanroom-grade Ethernet and redundant ring topologies. Similar programs in China and Indonesia provide tax holidays and fast-track permitting for factories adopting carbon-efficient automation. The resulting demand for hybrid wired-wireless architectures is fueling integrator pipelines across Southeast Asia.

High Upfront Cost of Retrofitting Legacy Equipment

Plants built before 2010 rely on Modbus-RTU or PROFIBUS networks that cannot natively carry Ethernet traffic, forcing operators to install gateways or entirely new cabling. Siemens’ Infrastructure Transition Monitor surveyed 1,400 executives and found 48% view decarbonization and digitalization as cost-prohibitive. Small enterprises across Indonesia and Thailand face higher financing hurdles, slowing upgrades despite modular retrofit kits entering the market.

Lack of Protocol Standardization Across Vendors

More than 20 Industrial-Ethernet variants persist, each with unique real-time extensions, complicating tool-chains and sparing-parts inventory. HMS Networks confirmed no single protocol exceeds 23% of new nodes, illustrating major fragmentation. Although OPC UA over TSN promises unification, mass firmware updates across millions of devices remain years away.

Segment Analysis

By Component: Services Surge as Operators Shift to Subscription Models

Hardware dominated 72.73% of Asia-Pacific industrial communication market size in 2024. Capital outlays covered industrial switches, gateways, and ruggedized field devices essential for greenfield plants and retrofits. Nevertheless, the migration to cloud-hosted analytics and cybersecurity overlays lifts services revenues at a 12.99% CAGR, the highest among component segments. Rockwell Automation’s State of Smart Manufacturing survey revealed that 79% of facilities operate connected devices, yet only 63% utilize artificial intelligence for efficiency, underscoring a latent appetite for managed analytics.

A parallel pivot toward software-defined networking compresses hardware margins. Vendors are increasingly bundling device management, threat monitoring, and firmware patching into tiered subscription plans, thereby widening their recurring revenue streams. Mitsubishi Electric’s BRIDGE remote-maintenance service and newly launched Serendie industrial-cloud platform exemplify a strategy to decouple earnings from hardware refresh cycles. Over the forecast horizon, services composition will likely shift toward outcome-based guarantees, such as “zero unplanned downtime” contracts tied to performance metrics.

By Communication Type: Wireless Gains as Factories Replace Cable Runs

Wired networks accounted for 63.75% of Asia-Pacific industrial communication market size in 2024, with Industrial Ethernet supporting high-precision motion control and protective relaying. Fieldbus protocols continued a secular decline, losing 2% of absolute installations. Safety-critical applications, governed by IEC 61508, still favor deterministic wired links that deliver microsecond-class jitter.

Wireless usage, however, is rising at a 12.56% CAGR. Private-5G campuses and Wi-Fi 6E now serve mobile autonomous vehicles, wearables, and hazardous-area sensors where cabling costs or vibration risks are prohibitive. WirelessHART retains niche strength in process plants, but IP-based wireless options are expanding rapidly as spectrum-sharing frameworks mature. Factories adopting licensed private-LTE report paybacks under three years due to reduced downtime and faster line re-configuration. As regulatory clarity around 6 GHz and mm-wave bands spreads beyond Japan and South Korea, adoption is expected to accelerate across ASEAN.

By Industrial Network Protocol: 5G and Private-LTE Disrupt EtherNet/IP Hegemony

EtherNet/IP captured 55.72% Asia-Pacific industrial communication market share in 2024 because of its deep penetration in automotive body-in-white lines and discrete assembly. Rockwell Automation’s live showcase of EtherNet/IP over 5G reveals efforts to extend wired determinism into wireless domains. PROFINET, EtherCAT, and CC-Link IE address regional or performance niches, yet none threatens EtherNet/IP’s installed base before 2030.

The headline challenger is private-5G. Licensed spectrum ensures predictable latency, and built-in network slicing supports segregation of safety and enterprise traffic. The Ministry of Internal Affairs and Communications' target of 50,000 millimeter-wave base stations by 2027 underpins capacity for mobile robotics. As equipment costs fall, greenfield plants may bypass cable-heavy topologies altogether, allowing 5G to chip away at wired leadership positions in flexible production cells.
