Industrial Internet of Things will Reach 43.5M Devices

As more machine-to-machine (M2M) applications are being created, Internet connectivity will become essential to numerous heavy industries around the globe. The installed base of wireless Internet of Things (IoT) devices in industrial automation reached 10.3 million in 2014, according to the latest worldwide market study by Berg Insight.

The number of wireless IoT devices in automation networks is now forecast to grow at a compound annual growth rate (CAGR) of 27.2 percent to reach 43.5 million by 2020.

There is a wide range of wireless technologies used in industrial automation with different characteristics and use cases. As an example, 802.15.4 based standards such as WirelessHART and ISA100.11a are major contenders at the field level in process automation networks.

Wi-Fi and Bluetooth are the most widespread technologies in factory automation while cellular connectivity typically is used for remote monitoring and backhaul communication between plants.

The increasing popularity of Ethernet based networks in factory automation is one of the key drivers for the popularity of Wi-Fi in such applications. Increased usage of standard devices such as tablets and smartphones in for example mobile HMI solutions is also an important driver for the adoption of Wi-Fi as well as Bluetooth in automation equipment.

"Companies are now deepening the integration between industrial automation systems and enterprise applications and the promise of IoT is getting more tangible by the day," said Johan Svanberg, senior analyst at Berg Insight.

Industrial Internet of Things Marketplace

The wireless IoT device market is served by a multitude of players from various backgrounds including global automation solution providers, automation equipment and solution vendors, industrial communication specialists and IoT communication specialists.

Emerson, Honeywell, GE and Yokogawa are leading vendors of 802.15.4 devices in industrial automation. Siemens, Cisco, Belden, Moxa, Schneider Electric and Eaton are major vendors of Wi-Fi devices while Eaton, GE and Sierra Wireless are important vendors of cellular devices for industrial automation applications.

Large multinational corporations are beginning to systematically develop and adopt best practices to maximize the benefits of IoT technology in every part of their organisations.

IT/OT convergence, smart factories, Industry 4.0 and the Industrial Internet of Things are all concepts which are part of the ongoing evolution of industrial automation.

According to Berg's assessment, innovation in sensor technology, wireless connectivity, energy harvesting, 3D printing, big data and cloud solutions -- along with seamless exchange of information between devices, systems and people -- paves the way for improved performance, flexibility and responsiveness throughout the enterprise value chain.

IoT Device Management Demand Gains Momentum

More forward-thinking CIOs and CTOs are focused on the adoption of the Internet of Things (IoT). Management challenges are top of mind for those who have already deployed a large number of sensors and associated network edge devices. Device management services are evolving in response to a greater breadth of new device technologies such as edge intelligence and related connectivity solutions, as well as the customer scalability and security of IoT deployments. But forward-looking suppliers are also preparing for a world where 41.3 percent of the connected devices will be using some form of Low Power Wide Area (LPWA) technologies by 2026. IoT Device Management Market Development Since IoT customers increasingly need to manage a larger fleet of connected devices, ABI Research now forecasts that IoT device management services will exceed $36.8 billion in revenues by 2026. Standardization is beginning to play a bigger role in device management services, as more connected devices use LPWA t

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service. Anywhere, Anytime Workplace Market Development   Although converging networking and security capabilities offer enterprises a promising solut

Cloud Edge Computing Demand Continues to Grow

Public cloud computing solutions are moving closer to the edge of networks where CIOs and CTOs are hosting new apps. The edge journey is well underway for forward-looking organizations as they seek to connect with customers, improve operational efficiency, and adopt digital business technologies to drive innovation. The latest worldwide market study by International Data Corporation (IDC) found that three-quarters of organizations plan to increase their edge computing spending over the next two years with an average increase of 37 percent. A combination of factors is driving this increased spending at the edge. Cloud Edge Computing Market Development The performance requirements of expanding workloads and new use cases that leverage artificial intelligence (AI) and machine learning (ML) demand greater compute capacity at the edge. In addition, the amount of data being stored in edge locations are rapidly expanding, and organizations plan to keep this data longer. As a result, the numbe
