Antennas Designed for Hazardous-Classified, Industrial Hardened Applications

Wireless communication has seen increasing prevalence in the industrial process measurement and control field for several years.  It has provided years of reliable communications for monitoring and controlling processes, where using cables is either too costly or impractical. The absence of wires saves space, reduces the potential for damage, and simplifies modifications to the equipment layout. Implementing wireless communications in hazardous areas, whether through WiFi or other radio frequency channels, presents a particular set of challenges to successful implementation. Points of network access and further transmission and receiving equipment can require a level of isolation and hardening appropriate for the hazardous environment. In response to customers' desire to incorporate the technology across an ever-widening array of application scenarios, vendors continue developing and releasing new products and technologies that expand the potential for industrial wireless communication.

IIoT Developments and Security Concerns

Upward of 27 billion devices connect as part of the massive confluence of technologies, networks, protocols, standards, and devices known as the Internet of Things (IoT). IoT is a network of computers and devices that capture and exchange vast volumes of data, which is then sent to a cloud-based service, aggregated with other data, and then exchanged with end-users to provide valuable insights. IoT is growing automation in homes, classrooms, shops, and several other industries and industries. 

The Industrial Internet of Things (IIoT) leverages many of the same technologies like IoT and applies them to the industrial world's diverse needs. IIoT is a category of technologies that capture and distribute data inside historically isolated industrial devices, contained in Supervisory Control and Data Acquisition (SCADA) systems and other Industrial Control Systems (ICS). They track and control essential industrial infrastructure, including factories, power plants, water systems, ports, other industrial installations, and some U.S.

Sensitive industrial infrastructure owners and operators are rapidly implementing IIoT technologies to maximize the development and distribution of goods and services, increase performance, improve safety and minimize costs. IIoT sensors and devices provide real-time monitoring and control to operators.  They also collect data on system output, further improving plant performance or production performance. For example, smart tools used on a production line could allow a company to monitor and evaluate its production process. Real-time production data could provide insight into plant conditions, discover additional plant capability, and predictive analytics can help detect corrosion within the refinery pipe.

These threats to modules, firmware and software, wireless networking, and most devices must include mitigation at the computer and system engineering level. The U.S. National Institute of Standards and Technology (NIST) and the European Union Agency for Cyber Security (ENISA) seek to guide the government and industry with some of their voluntary attempts to describe IIoT cybersecurity. Industry is collaborating with original equipment manufacturers (OEMs) and other manufacturers to establish reasonable safety capabilities in IIoT products to avoid burdensome regulations that are likely to quickly get out of date as the IIoT industry is vast and changing much faster compared to government legislation. 

Key Concerns

• Critical infrastructure owners and operators are rapidly adopting the IIoT to boost performance and maximize productivity, but this technology also brings increased cyber and other vulnerabilities. 
• The increased adoption of the IIoT, historically unsafe and isolated legacy systems come with new connected devices against a background of diverse yet growing safety standards for components, creates further possibilities for system access and eventual critical infrastructure access to the computer network by several malicious cyber players. 
• The rise in publicly and commercially accessible cyber resources makes it easier for more players to access vulnerable IIoT components. These devices are contained in critical infrastructure, allowing them to seek a range of effects that may not be detected, and present financial and possibly physical consequences.

IIoT and Wireless Connectivity

The Industrial Internet of Things (IIoT) refers to sensors, controllers, actuators, tools, and other devices interconnected with industrial computer applications, including manufacturing and energy management. This connectivity facilitates collecting, distributing, and reviewing data, potentially promoting productivity and quality improvements, and other economic benefits. The IIoT is an evolution of a distributed control system (DCS) that uses cloud computing to refine and optimize process controls, allowing for a greater degree of automation. 

In the manufacturing industries, the term industrial internet of things refers to the IoT industrial subset. Improved efficiency, analytics, and the workplace's transformation are future advantages of the industrial Internet of things. 

While connectivity and data acquisition is essential for IIoT, they are not the ultimate objectives but rather the basis and path to something larger. Predictive maintenance is an "easier" application of all technology related to current asset and management systems. Smart maintenance systems will minimize unnecessary downtime and improve efficiency, estimated to save up to 12 percent over planned repairs, reduce total maintenance costs by up to 30 percent, and eliminate breakdowns by up to 70 percent.

Wireless connections are increasingly used in IIoT deployments to boost industrial data services' operational communication, such as capturing vast process data, interacting with industrial robots, and monitoring machines/parts/products on and beyond the factory floor. 

Industrial users typically play a much more decisive and active role in deciding wireless services in their plants than personal customers in the wireless market. A collaboration between operational technology (OT) engineers, information technology (IT) device architects, and wireless network planners is inherently a wireless system architecture for IIoT applications.  The newly founded 5G Alliance for Connected Industries and Automation (5G-ACIA) has provided some inputs from industrial manufacturers in the form of white papers.  

There are no one-size-fits-all wireless solutions for industrial use cases as the service requirements, and operating environments may differ vastly from one another. Earlier industrial wireless networks provided connectivity in each single vertical manufacturing sector. As a result, the solutions that function well under the specific service requirements and operating conditions may only yield limited value in different use cases. Wireless success in more emerging IIoT applications will require wireless networks to facilitate the broader and deeper digital contact with industrial systems and provide flexible interfaces and quick deployments while keeping data integrity.

An Excellent White Paper for Understanding Wireless Networking in Hazardous Areas

A potentially explosive atmosphere exists when a gas, vapor, mist, or dust, alone or in combination, occurs in situations where it may ignite under specific conditions. A "hazardous" or "classified" area are places with highly combustible atmospheres that are potentially explosive.

Local and international regulations exist to minimize the risk posed in explosive atmospheres by the energy contained in and required by operating networks and IoT products. A gradual harmonization of these regulations continues to be structured and defined by the IEC and European and US standards.

Industry associations and standards bodies continue to work together to resolve classifying explosive materials and establish standards for the safe operation of networking equipment and IIoT (Industrial Things Internet) products in hazardous areas. Because different organizations perform the work in other areas, understanding which criteria are applicable under different conditions can be difficult.

Aruba Networks has been at the forefront of wireless networking in industrial environments. Their white paper entitled "BUILT TO BLAST: Industrial Internet of Things Hazardous Environment Infrastructure" discusses the various types of dangers, criteria, and conditions that need to be considered before deploying wireless network infrastructure in explosive environments. You can download the white paper here.

The growth of connected industrial IoT devices moves in unison with initiatives to improve operations, maximize efficiency, allow better inventory management, and enhance plant safety. Understanding the unique requirements of wireless networking and communications in hazardous areas is critical.
