Busting the Myths About FHSS for Industrial IoT
IT/OT convergence has shaken the way businesses operate from a networking, connectivity and communications perspective. As IT decision makers look to find technology that will support the needs of modern digital networks, it is easy to overlook Radio Frequency (RF) solutions. Frequency Hopping Spread Spectrum (FHSS) technology is a viable option that has been around for decades. With the right solution in place, FHSS technology is reliable and robust enough to get important data from the field back to the central office. With newer, high-speed and high-throughput options, it can be ideal for helping solve modern convergence challenges. FHSS technology is well-known for its use in OT networks in industrial settings, but the IT side might not be as familiar with the technology. There are a number of myths about FHSS technology that need to be clarified in order for an IT decision maker to understand its potential. Today we’re going to bust three big myths: Myth One: FHSS Technology is Not Secure Enough for Modern IIoT Networks 900 MHz FHSS technology leverages an unlicensed spectrum which has led to the misperception that it is vulnerable to jamming and DoS attacks. The reality is that the signal is constantly hopping in the spectrum and does not stay on a single frequency for long. This one of its greatest strengths and makes it much more difficult to jam. IT decision makers who are greatly concerned with security should also know that some manufacturers offer two layers of security. The first is the natural built-in protection from the frequency hopping and the second is 128 or 256 bit AES encryption. Myth Two: Crowded Spectrums Lead to Poor Coverage Network congestion is a long-standing misperception associated with FHSS technology. Operators are often concerned that performance could be affected in an unlicensed spectrum if too many devices are trying to use it at once. However, the frequency hopping nature of the technology actually serves as a strength. The jumping allows the technology to identify the better channels, even in areas that are known for being noisy and congested. FHSS technology has been proven and trusted by the U.S. military for decades to perform in situations where lives are on the line. Myth Three: FHSS Technology is Best Suited for Industrial Environments Like Oil and Gas In oil and gas and military circles, FHSS is frequently used and widely known as a strong wireless communication option. However, the technology may not even be on the radar of an IT decision maker tasked with new responsibilities as the OT/IT divide closes. What IT decision makers need to know is that FHSS technology is also currently used in networks completely outside the scope of traditional industrial networking. Here are a handful of unique ways FHSS is currently being used: Oceanic Monitoring and mapping Auto and Boat Racing Testing for Electric Cars Plant Automation Asset Tracking in Healthcare Golf Course Communications and Golf Cart Monitoring Aquarium research A Good Fit FHSS technology fits nicely into the evolving technology landscape – especially when data needs to be transported from the access layer back to the business office. Despite the challenges that OT and IT teams face as they learn to work closer together, FHSS remains a proven, reliable option to help bridge the gap.
Robotics & IoT Merging Together
The Internet of Things (IoT) has made its appearance in a substantial number of industries, most recently manifesting itself in the the realm of robotics. IoT technologies and standards open the door for new robotic capabilities that are powered by cloud computing, communication with other robotic systems and sensor input from the environment around them. Recent research has pointed to a new opportunity for robotics to operate beyond the scope of what was possible just a few years ago. As we look at a future of data and connectivity at every end point – from our cars, to our homes, to our businesses – it’s clear that we’ve just begun to scrape the surface of what is possible with the rapid expansion of IoT throughout the world. In a recent report, ABI research coined the, “Internet of Robotic Things (IoRT),” defining the concept, “where intelligent devices can monitor events, fuse sensor data from a variety of sources, use local and distributed ‘intelligence’ to determine a best course of action, and then act to control or manipulate objects in the physical world, and in some cases while physically moving through that world.” The research certainly backs recent claims that robotics are going to leave a significant mark on the IoT industry. Take a look at the key statistics that Forbes recently reported on Robotics: 4% of developers are building robotics apps today. 45% of developers say that Internet of Things (IoT) development is critical to their overall digital strategy. 4% of all developers are building apps in the cloud today. RF Technology in the IoRT World As the entire technology landscape changes it is more important than ever for RF technology to adapt in order to meet new industry demands. Manufacturers in the hardened, wireless communication industry have taken note and set their eyes on all things IoT by developing Sensor-to-Server (S2S) communication solutions. Some of these wireless IoT communication solutions providers are offering platforms to host third-party applications in addition to creating the communication links for devices. This is an entirely new class of wireless IoT communication solutions that has the staying power needed in the midst of technology evolution. Robotic IoT Future Some companies using wireless S2S solutions, have already begun to incorporate IoRT into their networks. Real-life use case examples of robotics for IoT networks that are in the works today include: Semi-autonomous robotic geophysical surveying platforms for detection of unexploded ordnance. With an S2S communication solution, this use case will provide real time kinematic base station GPS corrections and combined geophysical data to a mobile command and control vehicle for concurrent advanced data processing by rear support group linked by MiFi or Satellite communications. A ‘ship-to-shore’ link for an ocean going wave-powered autonomous robot. As robotics systems adapt to the new technology landscape, they will increasingly integrate with IoT networks. With these new advanced robotics capabilities, businesses will see new opportunities for automation and efficiency to further advance operations and will be able to leverage this new technology for competitive advantage.
Where is RF Technology for Oil and Gas Headed?
The entire landscape of the oil and gas industry is changing. Not only has the industry downturn forced operators to rethink their business models, but the RF technology supporting industry operations is quickly changing. It is more important than ever to make intelligent business decisions with the right technology in place. As a decision maker for your organization, you need to be aware of the technology that is pointing towards the future of automation and RF technology. Challenge yourself to think beyond basic command and control and picture a fully connected network – from Sensor-2-Server. Here’s a quick snapshot of the technology movement we are seeing in the oil and gas industry right now: The installed base of wireless Machine-to-Machine (M2M) devices is growing. More technology in the field allows operators to access more data from more sensor access points – on a grander scale than ever before. The ability to leverage Big Data supports intelligent decisions that will optimize business operations and cut down on expenses. The Industrial Internet of Things (IIoT) is the future of communication technology. With IIoT, data can be transported from its collection point to wherever it needs to go – anywhere in the network. This has sparked a convergence of OT and IT operations, driving RF technology networks closer to the concept of complete connectivity. With a fully connected network, decisions are made based on comprehensive data, which drives intelligent problem-solving. With that type of insight, you could better disperse your resources, leaving a positive impact on the organization for years to come. Sensor-2-Server (S2S) solutions that deliver intelligence to the access layer are critical to industry success. S2S solutions bring intelligence to the access layer, enabling edge devices to do more than simply transmit data. They support highly detailed data analysis such as predictive analytics. Imagine the operational decisions you could make with a complete set of data from the outermost edge of your network all the way back to the server. IoT App development is the next big thing. Programmable third-party applications are on the horizon of the wireless RF solutions market. These apps will support machine learning, distributed intelligence, predictive maintenance, and more at the edge of the network. Technology is being designed to enable these applications – which have the potential to lead the industry to the next frontier of RF technology.
