Industrial Automation Wireless Market Shows Strong Growth Momentum
The industrial automation industry continues to adopt wireless IoT technologies as manufacturers seek better visibility, asset management, and operational efficiency. According to industry research from Berg Insight, global shipments of wireless devices for industrial automation applications reached approximately 5.8 million units in 2025.
These wireless devices represented around 6% of newly connected industrial nodes worldwide. Moreover, market analysts expect annual shipments to grow at a compound annual growth rate (CAGR) of 8.1%, reaching about 8.5 million units by 2030.
From an industrial engineering perspective, this growth reflects a major shift in how companies design control systems. Wireless technologies are no longer limited to temporary monitoring tasks. Instead, they now support long-term industrial data acquisition, predictive maintenance, and digital transformation strategies.
Wireless IoT Supports Continuous Monitoring in Process Industries
Process industries such as oil and gas, chemical production, power generation, and water treatment require continuous monitoring of critical variables. Therefore, industrial wireless instrumentation has become an important extension of traditional wired control architectures.
Field devices collect data related to pressure, temperature, vibration, flow, and equipment status. These measurements help operators improve process stability and reduce unexpected downtime.
In modern DCS and PLC environments, wireless sensors increasingly complement conventional field networks. They provide additional measurement points without requiring extensive cable installation or complex infrastructure modifications.
Based on practical industrial projects, wireless monitoring solutions often provide the greatest value in locations where cable installation creates safety risks or high maintenance costs.
Factory Automation Adopts Wireless Condition Monitoring Solutions
Wireless technology is also expanding beyond process industries into factory automation applications. Manufacturers increasingly deploy wireless sensors for machine condition monitoring, production equipment diagnostics, and maintenance optimization.
For example, vibration sensors installed on rotating equipment can transmit real-time machine health data to industrial gateways. Maintenance teams can then analyze this information through industrial software platforms and schedule repairs before failures occur.
However, wireless solutions do not completely replace traditional industrial communication networks. Ethernet-based systems, fieldbus networks, and industrial backplanes remain essential for high-speed control applications.
Instead, wireless technologies create additional monitoring layers that improve visibility across manufacturing facilities.
Industrial Wireless Technologies Improve Connectivity in Difficult Areas
Many industrial facilities still rely on wired communication between sensors, controllers, and supervisory systems. However, wiring becomes challenging in hazardous zones, remote locations, mobile equipment, and temporary installations.
Wireless networks provide an effective alternative in these environments. They reduce installation complexity and allow engineers to connect equipment that was previously difficult to monitor.
Leading industrial wireless technologies include Wi-Fi, IEEE 802.15.4, Bluetooth, cellular communication, IO-Link Wireless, and proprietary radio solutions operating in ISM frequency bands.
Moreover, industrial wireless networks often support gateway-based architectures. These gateways collect field data and transfer information to PLC, DCS, SCADA, or cloud-based platforms.
Major Industrial Automation Suppliers Expand Wireless Product Portfolios
Major automation manufacturers continue to strengthen their wireless industrial solutions. Companies such as ABB, Emerson, Honeywell, Omron, Rockwell Automation, Schneider Electric, Siemens, and Yokogawa now provide wireless field devices and communication products.
These suppliers integrate wireless capabilities into broader industrial automation ecosystems. Their solutions support applications ranging from process control and factory automation to remote asset monitoring.
In addition, specialized sensing companies such as Balluff, Banner Engineering, Endress+Hauser, ifm electronic, Pepperl+Fuchs, SICK, Turck, and Vega provide industrial wireless sensing products for different manufacturing environments.
The increasing involvement of established automation suppliers shows that wireless communication has become an important component of future control system architectures.
Industrial Wireless Gateways Connect Remote Assets and Control Systems
Industrial networking companies are also expanding wireless product offerings. Siemens, Cisco, Belden, Moxa, and Phoenix Contact provide industrial routers, gateways, and access points that support both wired and wireless infrastructure.
These products allow factories to connect isolated equipment areas while maintaining communication with existing PLC and DCS platforms.
Cellular IoT gateways are especially useful for distributed automation systems. They support remote monitoring of pipelines, substations, renewable energy installations, and geographically separated industrial assets.
Major suppliers in this segment include Teltonika Networks, Cisco, Moxa, Siemens, HMS Networks, Phoenix Contact, Advantech, Robustel, Digi International, and InHand Networks.
Cyber Security Becomes a Core Requirement for Industrial IoT Systems
As industrial networks become more connected, cyber security has become one of the highest priorities for automation engineers and system integrators.
The integration of operational technology (OT) and information technology (IT) increases the number of communication points inside industrial environments. Therefore, manufacturers must protect wireless devices, gateways, controllers, and control software from potential security threats.
Modern industrial wireless solutions increasingly include security functions such as encrypted communication, device authentication, network segmentation, and secure remote access.
From field experience, cyber security should be considered during the initial system design stage rather than added after installation. A secure industrial automation architecture requires cooperation between control engineers, IT specialists, and equipment suppliers.
Wireless IoT Drives the Future Development of PLC and DCS Systems
Wireless connectivity will continue to influence the evolution of industrial automation systems. PLC, DCS, SCADA, and industrial edge platforms will increasingly combine wired control with wireless data collection.
However, engineers must select communication technologies according to application requirements. High-speed closed-loop control still depends on deterministic wired networks, while wireless solutions provide flexibility for monitoring and diagnostics.
Moreover, the growth of industrial AI and digital twin technologies will increase demand for more connected field data sources.
The future industrial plant will likely use a hybrid communication model that combines Ethernet, fieldbus, wireless sensors, and edge computing platforms.
Industrial Wireless IoT Application Scenarios
Remote Equipment Monitoring in Energy Facilities
Power plants and renewable energy sites often contain equipment distributed across large areas. Wireless vibration and temperature sensors can monitor transformers, motors, pumps, and rotating machinery.
These systems reduce manual inspection requirements and improve maintenance planning.
Hazardous Area Monitoring in Process Plants
Chemical and petrochemical facilities require continuous monitoring in areas where cable installation is expensive or difficult.
Wireless instruments can provide additional process measurements while reducing installation complexity.
Smart Factory Machine Health Management
Manufacturing plants use wireless sensors to collect machine condition data. Production teams analyze this information to improve equipment availability and reduce production interruptions.
Industry Outlook: Wireless Connectivity Becomes a Key Layer of Automation Architecture
The rapid growth of industrial wireless IoT devices indicates a broader transformation within the automation industry. Wireless communication is becoming a practical tool for improving asset visibility, operational efficiency, and maintenance strategies.
Although traditional PLC and DCS communication networks remain fundamental, wireless technologies add valuable flexibility for modern industrial applications.
In the coming years, successful industrial automation projects will depend on balancing connectivity, reliability, cybersecurity, and application requirements. Companies that adopt suitable wireless solutions will gain better control over complex industrial operations.
