    What is IoT (Internet of Things)?

    The Internet of Things (IoT) refers to the vast network of physical devices integrated within sensors, software, and other technologies to connect and exchange data over the internet. These IoT-connected devices enable smart automation and data-driven insights across a wide range of applications, including homes (climate control, security systems), industries (IIoT, supply chains), cities (traffic management, parking), and healthcare (patient monitoring, fall detection). The premise of IoT is about making common technologies “smart” by sharing data and improving their efficiency and performance.

    IoT extends digital intelligence beyond virtual worlds by merging the physical and digital realms. The integration of hardware and software enables greater efficiency, higher levels of automation, and improved decision-making. For example, a sensor on industrial machinery could monitor its own wear and tear, well before it fails. On the other hand, a connected vehicle can provide performance-related information to engineers thousands of miles away.

    The day-to-day lives of consumers and the operational efficiencies of large-scale industries will continue to experience changes due to the IoT. For product-based companies navigating complex manufacturing systems, IoT-generated data creates new requirements for managing product information across the entire lifecycle.

    The stream of performance data generated by connected products provides continuous feedback to product designers, engineers, and service personnel across all stages of the product lifecycle. As such, today’s product lifecycle management (PLM) systems are no longer simply responsible for providing access to product specifications. These systems must also provide access to real-world usage data collected from deployed products.

    How IoT works

    The operation of the IoT is based on a multi-layered, interconnected design that transforms raw physical data into actionable intelligence. Each layer has a defined function: collect, transmit, process, and act on data.

    • Device layer: Sensors and communication modules embedded in physical objects collect data about the object’s environment and/or status (temperature, motion, location, etc.) and report this information to the next layer in the IoT stack.
    • Connectivity layer: Devices send their collected data across networks such as WiFi, Bluetooth, Low-Power Wide Area Network (LPWAN), or cellular networks to either cloud-based platforms or an edge device.
    • Data processing layer: Incoming data streams received by cloud-based platforms or edge devices are processed, analyzed, and stored for future use.
    • Application layer: Processed data is sent to users through applications (dashboards, mobile applications, enterprise systems) to enable them to make decisions, automate actions, optimize operations, etc.
    • Feedback and control layer: IoT devices use processed data to autonomously respond to changes and adjust as needed, i.e., turn off a piece of malfunctioning equipment or adjust thermostat temperatures.

    This multi-layered structure allows IoT devices to always operate automatically with very little, if any, direct human involvement. Data flows continuously between the layers of the IoT stack creating continuous feedback loops, which optimize the overall system’s performance over time.

    Fundamental components of IoT

    Smart devices are made possible by several IoT technology building blocks working together to provide connected intelligence. These building blocks form the foundation of the structure on which smart devices are built.

    • Sensors and devices: Sensors capture environmental data (e.g., temperature, movement, humidity, pressure, etc.) and send this data to a central system for processing. Sensors convert the physical phenomenon they measure into a signal, which is then sent to a computer.
    • Connectivity: Networks and communication protocols are used to connect devices to the system’s processing capabilities via cellular networks, WiFi, Bluetooth, MQTT, Zigbee, LoRaWAN, etc. Connectivity options depend on a variety of factors, such as how far from the system a device will be located, how much power it will consume, how much data it sends to the system, and where the system will be deployed.
    • Data processing and analytics: Once raw sensor data reaches a processing center (which could be an on-site server, an edge device, or a cloud-based service), the data is processed and transformed into actionable information using algorithms, AI, or predefined rules. It’s at this level that decisions are made about what information is important and what actions need to be taken.
    • User interfaces and applications: User interface applications (dashboards, mobile apps, and enterprise software) provide users with the ability to view device status and trends, configure devices, and respond to alerts. In essence, these applications serve as a connection point between the data generated by machines and the decisions made by humans.
    • Security and compliance: IoT systems must have robust security measures in place to prevent unauthorized access to the system (e.g., encryption, authentication, access control), ensure that all collected data remains private (regardless of its location within the system), and meet all applicable regulatory requirements. Security must exist across every aspect of an IoT system, from device firmware to cloud-based infrastructure.

    Performance features and capabilities of IoT

    Certain performance characteristics of IoT differentiate it from other technologies (traditional IT) and allow for the development of new methods of operation. These features enable IoT to deliver responsive, smart environments that can adapt their behavior to changing situations.

    REAL-TIME DATA COLLECTION AND STREAMING

    Continuous collection and streaming of live data by devices is a key feature of IoT technology. An IoT device’s ability to collect data enables continuous monitoring of an organization’s operating environment, providing awareness of changes and the opportunity to act in response as they occur.

    AUTOMATION AND INTELLIGENT CONTROL

    Systems execute automated responses based on sensor readings and predefined logic without human intervention. A manufacturing line can adjust parameters when quality metrics drift. A hotel building can optimize energy usage based on guest occupancy patterns.

    REMOTE ACCESS ACROSS DISTRIBUTED ENVIRONMENTS

    Cloud platforms enable users to monitor and control devices from anywhere with internet access. Aras notes that bringing “real-time IoT and analytics into the digital thread” enables manufacturers to “deepen visibility across the product lifecycle, elevate service operations, and accelerate data-driven decision-making – all within a unified PLM environment”. For global enterprises managing products across distributed facilities, this remote capability is essential.

    INTEGRATION WITH AI AND MACHINE LEARNING

    The use of AI and machine learning to analyze IoT data streams and develop predictive insights lays the foundation for advanced analytical techniques. Analysis of IoT data streams using machine learning algorithms can predict when equipment will fail, optimize resource allocation, and identify efficiencies buried in vast data volumes that would be impossible for humans to process manually.

    SCALABILITY AND INTEROPERABILITY

    The scalability and interoperability of IoT architecture enable the integration of tens of thousands or even millions of devices across a wide variety of environments. Standardized communication protocols and APIs enable devices from multiple manufacturers to communicate with one another, forming an integrated ecosystem rather than isolated silos.

    Advantages propelling IoT forward

    Implementing IoT-based solutions for businesses delivers benefits in three main areas: operational (the way you work), financial (your bottom line), and strategic (your competitive advantage). The technology delivers measurable improvements that justify the $298 billion in enterprise IoT spending recorded in recent data.

    • Increased operational performance: By automating non-productive, manual processes, you need less employee intervention, and you can allocate resources more effectively. For example, an IoT-based manufacturing environment can adjust its production parameters based on data collected from each device’s performance on the shop floor.
    • Data-driven decision-making: Using concurrent information from connected devices makes for quicker, more confident decisions about their actual status, rather than relying on educated guesses. Businesses can evaluate trends in sensor data to identify new opportunities and address problems before they escalate into major issues.
    • Reduced costs: IoT-based predictive maintenance and process improvement result in significantly reduced operating costs. Manufacturers, in particular, leverage connected sensors to reduce costs and downtime and improve operational efficiency. Additionally, smart inventory systems send notifications to management when stock levels are low, reducing excess inventory carrying costs.
    • Safety and security: Continual monitoring and automatic alerts help prevent accidents and security breaches. IoT-based sensors detect abnormal behavior (such as equipment malfunctions or unauthorized access attempts) and automatically alert for immediate response, protecting both personnel and assets.
    • Enhanced customer experience: Providing personalized, intelligent services increases customer satisfaction and loyalty. Smart devices provide customized experiences for customers based on their preferences across industries, such as retail, hospitality, and consumer products.
    • Optimization of energy consumption and sustainability: Energy monitoring provides organizations with the ability to identify inefficiencies and improve their operations. IoT devices track energy usage patterns, predict when maintenance is required to prevent unnecessary equipment operation, and enable integration with renewable energy sources to optimize sustainability for product development.
    • Faster product development cycles: Feedback from connected products’ field data to design and engineering teams creates a continuous development cycle. Product development cycles are accelerated by actual usage patterns (rather than laboratory testing), resulting in faster, better product iterations and improvements.
    • Competitive advantage: Organizations that develop and implement early IoT-based solutions establish significant advantages in markets where speed and responsiveness are critical. With over 18 billion IoT devices in use and growing 13% year over year, organizations that leverage these technologies position themselves ahead of competitors still relying on traditional approaches.

    Different types of IoT applications

    The types of IoT differ by sector, with each type having unique uses depending on the requirements of the different businesses’ processes. Identifying these categories will help organizations develop an IoT application strategy aligned with their strategic goals.

    CONSUMER IOT

    Consumer IoT encompasses smart homes, wearable devices, connected vehicles, and health-monitoring devices that improve consumers’ day-to-day lives. Examples of consumer IoT products include smart thermostats that learn household temperature preferences, wearable devices such as fitness trackers that monitor an individual’s physical activity, and connected vehicles that can monitor vehicle operation issues, such as navigation and diagnostics. The consumer segment is the largest driver of IoT adoption, as individuals seek to automate and make their personal lives easier with technology.

    INDUSTRIAL IOT (IIOT)

    Industrial IoT connects industrial equipment, supply chain assets, and production systems to improve efficiency and reduce downtime. Industrial sensors are used to monitor equipment health for predictive maintenance before failure and to track inventory movement through global supply chains. As manufacturers recognize the benefits of real-time operational data for improving production efficiency, the IIoT market has grown to approximately $275.7 billion.

    COMMERCIAL IOT

    Commercial IoT applications exist in retail, hospitality, office buildings, and commercial enterprise facilities. Commercial IoT enhances business operations for these entities. For example, smart building systems that can optimize HVAC and lighting based on occupancy, and retail store applications that use sensors to measure customer movement patterns and inventory levels. Implementing IoT solutions for commercial businesses reduces energy costs and improves customer experience by optimizing business operations through data.

    SMART CITY IOT

    Cities use IoT to manage traffic, ensure public safety, monitor the environment, and maintain infrastructure. Smart traffic management systems adjust signal timing in response to current conditions, smart streetlights reduce energy usage, and sensors monitor air quality and water systems. Cities implement IoT to improve citizens’ quality of life and deliver more efficient municipal services.

    HEALTHCARE IOT

    Healthcare IoT enables remote patient monitoring, continuous vital signs monitoring, and connected diagnostic equipment. Patients wear sensors that continuously transmit health information to their providers, and hospitals use connected diagnostic equipment to improve asset utilization and patient care. Healthcare IoT has been growing rapidly as healthcare providers seek to extend the reach of healthcare services beyond traditional clinical environments.

    IoT vs. IIoT

    While both IoT and IIoT (Industrial Internet of Things) rely on the same core technologies, they address different use cases with distinct requirements. IoT’s use cases include general-purpose consumer applications such as smart homes, wearable technology, and office automation. Some IIoT use cases include industrial manufacturing equipment, production systems, and supply chain networks.

    The scale and reliability requirements differ significantly between IoT and IIoT. In the case of consumer IoT devices, an occasional loss of connectivity or a short period of downtime will likely have minimal to non-existent impact on the end user. Conversely, IIoT systems require extremely reliable connectivity and performance; failure of either communication or equipment can lead to downtime of entire production lines, wasted material, and losses of potentially thousands of dollars per minute.

    In addition to the security concerns of IoT devices, security breaches in industrial settings bring far greater risks. While a breach of a smart thermostat may create inconvenience, a breach of an industrial control system (ICS) could result in damage to equipment, the environment, or workers. In turn, IIoT systems must adhere to stringent safety certifications and cybersecurity standards due to their critical mission-critical nature.

    For product-driven enterprises, IIoT creates new demands on PLM systems. Aras’s partnership with BellaDati to integrate real-time IoT analytics into PLM platforms demonstrates how manufacturers need unified environments that connect product design data with operational data from deployed assets. This integration enables organizations to close the loop between how products are designed and how they actually perform in industrial environments.

    Challenges and considerations

    Despite the many advantages of IoT, companies face many hurdles when implementing it. The barriers to implementing IoT are not limited to technical challenges; they also include operational and strategic ones. Understanding these challenges will help companies prepare for effective deployment.

    • Security and privacy risks: Since IoT devices are vulnerable to cyberattacks when they connect to an open network, every connected device becomes a potential entry point for hackers.
    • Interoperability: Different devices and platforms developed by different companies cannot interact with one another if no standard communication protocols or interfaces are established between them.
    • Data management: Companies must also develop methods to manage the massive volumes of data produced by IoT sensors. Companies need scalable data storage solutions and processing capacity, along with established processes for determining which data to retain and which to delete.
    • Regulatory compliance: Organizations must meet industry-specific data privacy and safety standards and regulations that vary by region and sector.
      Scalability and maintenance: As companies deploy thousands of IoT devices across the globe, they must figure out how to manage and update the firmware of those devices remotely and efficiently.
    • Network reliability and bandwidth: IoT systems depend on consistent connectivity, but network outages, latency issues, or insufficient bandwidth can disrupt critical operations.
    • Initial implementation costs: The initial cost of deploying IoT systems in the form of hardware, software, and personnel to integrate and implement the system could be a barrier to some organizations wanting to use IoT.

    Future trends in IoT

    Ultra-fast, low-latency 5G connectivity has opened up possibilities for IoT, which has historically been limited by networking issues. For example, manufacturing robots can now communicate with millisecond accuracy. Vehicles can process sensor information instantaneously and make adjustments as needed. This also supports edge computing, where data is processed at the same location as the IoT device rather than on a remote server in the cloud.

    AI is enabling IoT to transition from being a reactive monitoring system to a predictive intelligence system. AI uses algorithms to predict when equipment will fail, optimize energy use, automate complex decision-making, and continue learning from experience. In addition to AI, digital twins are another technology that enables predictive intelligence for IoT. A digital twin is a replica of an asset in a virtual environment that replicates the conditions of the physical environment. Using digital twins, engineers can test different scenarios and optimize their operations in the virtual model before physically interacting with the actual asset.

    The development of green IoT will promote sustainability through energy-efficient IoT devices, smart grid management to balance renewable energy sources, and systems that minimize industrial waste. Sustainable IoT will also provide connected sensors to measure environmental impacts and identify opportunities to optimize operations and improve efficiency, while promoting ecological responsibility.

    For manufacturers navigating these trends, integrating IoT data with product lifecycle management becomes essential. Aras’s approach to bringing real-time IoT analytics into unified PLM environments positions organizations to leverage emerging capabilities while maintaining visibility across the complete product lifecycle. Platforms that seamlessly link design, manufacturing, and operational intelligence will hold a competitive advantage as connected products generate unprecedented volumes of field data.
