Solving The Challenges of Remote Wi-Fi in the Industrial Internet of Things
Most of us can relate to the frustration of when the Wi-Fi is down, or running slowly, or if we travel away from an established network and aren’t able to connect to another one nearby. The lack of Wi-Fi makes it impossible to check our emails, look up something on the internet, connect with others, or get our work done efficiently. In short, it makes us feel a little helpless and a whole lot of cranky because we’ve become way too accustomed to getting the information we want – when we want it – and staying in 24/7 connection with our world. Now, if we’re challenged by our Wi-Fi experiencing a service blip in a metropolitan area, imagine a remote industrial setting like an oil pad, a water treatment plant, or a rural electric tower. All of these reside in what is known as the access layer – or at the very outer edge of an IT network. Not only is there usually no internet connectivity in the access layer, but these devices are typically operating in rugged terrain where they’re experiencing extreme and volatile weather conditions such as wind, snow, blistering heat, tornadoes, dust storms, etc. Each of these access layer settings is part of a larger industrial Internet of Things (IIoT) network that connects the information gathered from local sensors that transmit or receive operational data. From there, they pass it along through subsequent network touch points all the way to the IT department at headquarters where this data is collected, analyzed, and acted upon for improved decision making. So, at the access layer – sometimes in the middle of nowhere where there can be no Wi-Fi networks for miles – talk about being disconnected from the world! Adding the environmental component to that, as well as the fact that most of these remote sites aren’t adequately monitored and data security is at risk, it makes your occasional Wi-Fi challenges seem a bit tame, yes? Here’s where wireless IIoT communications technology can help transmit this critical sensor data from remote industrial locations with no Wi-Fi connectivity all the way to where they’re supposed to go – and at very high speeds. This week, FreeWave is launching its new WavePro™ WP201 shorthaul and Wi-Fi platform that delivers secure collection, control, and transport of Voice, Video, Data, and Sensor (VVDS™) information from the access layer. Think of it as high-speed, rugged Wi-Fi connectivity that can be positioned in that oil pad, power plant or wherever Wi-Fi is needed. It will not only connect these sensors to the internet, but can also transport voice and video to create an instant in-field network, provide greater visibility into what’s going on at these sites, and better protect remote assets. The Advent of Short Haul and the Access Layer Change is inevitable, and change is taking place in SCADA, M2M and IIoT networks. SCADA networks started as networks that transported periodic process updates and used low bandwidth networks with longer links to meet their mission. Today, remote SCADA and Wi-Fi networks are transporting more data from more sensor data with greater frequency in order to drive operational efficiency into business processes. SCADA and M2M networks are becoming more multi-functional than their predecessors. These networks are transporting more than sensor data from the remote site to the enterprise. These networks linking remote sites to the enterprise network are now transporting: Video for remote process monitoring, enhanced site security and theft deterrence Voice, since cellular coverage is not ubiquitous Data so field personal have access to information needed to work efficiently This combination of data types is what FreeWave terms as VVDS™ (voice, video, data and sensor). VVDS transport is now a requirement for your wireless network. Another change occurring in traditional SCADA networks is that link distances are decreasing. In the past, SCADA networks with wireless links of more than 10 miles were common. Today, wireless links in excess of 10 miles typically use high speed, microwave, point-to-point (PTP) systems because of the increased capacity demands of VVDS. The WP201 links the formerly unconnectable and is designed to not only meet the harshest environmental conditions, but also encrypts the data to keep it secure and protected. It can be used in a wide variety of industries like oil & gas, utilities, mining, disaster recovery, facility automation – anywhere where field sensor information needs to be transmitted to servers for Sensor-2-Server™ (S2S™) connectivity. The applications are almost limitless. With higher speed, shorter wireless links, FreeWave defines wireless networks in three tiers: Long Haul (or the Distribution Layer) are wireless links from 5 miles, and greater and are typically implemented using high speed, PTP microwave systems. Short Haul (or the Aggregation Layer) are wireless links from 1 to 8 miles that are easily implemented using high speed, 2.4GHz or 5GHz radios with directional antennas to create point-to-multipoint (PMP) networks for data and information aggregation, or PTP links that provide network ingress/egress points. Close Haul (or the Access Layer) are PMP networks with wireless links operating from a few feet to a couple of miles to transport VVDS data. Designing and deploying wireless networks using a layer approach that enables each layer to be optimized for transport and for cost ─ leveraging the right equipment at the right point. The WP201 and its remote Wi-Fi and short haul capabilities is the first in a series of S2S products that FreeWave is offering to be that critical communication bridge in the IIoT world. So in your own operations, what are some ways you might incorporate the WP201 into your network?
IIoT Top News: 2015 News Round-Up
Let’s take a moment and appreciate the excitement 2015 brought for the IIoT: As we look back at the top articles from the year, we were intrigued to learn that cooperative utilities actually have the largest penetration of smart grid meters per percentage of customers, according to Greentech Media and the U.S. Energy Information Administration. It’s interesting to see the largest publicly-owned utility companies in the U.S. are not the leader in deploying smart meter systems. Another topic that caught our eye this year focused on big data initiatives and how they will improve operational efficiencies by the large-scale storage and transfer of volumes of information safely and securely. Companies don’t always see the value in updating information governance policies because there isn’t always a direct reward and no direct penalty for non-compliance. Tim Jennings, Ovum chief research officer, believes as big data continues to grow within the company infrastructure, it is time to consider the security, availability, and time spent storing data. Speaking of Big Data… It is hard to grasp the magnitude of data transferred throughout the cloud. Today, as big data goes to work, it is transforming industrial facilities, and as Forbes states, “they have grown increasingly complex and yes, every machine, every pipeline, every transmission point collects data ready to be read.” Of course, a 2015 news review would not be complete without at least one mention of unmanned systems. Whether the want/need was for industrial, commercial or government applications, the thing on everyone’s mind was how many cool ways this technology could be deployed in the future. While there were many examples to choose from, DARPA certainly caught a lot of attention from its new autonomous submarine-hunting ocean drone. Yes, you read that right! Finally, as we ease our way into 2016, we would like to share the rest of the top technology and IIoT stories from 2015. This year’s round-up highlights articles about: utilities, manufacturing, oil and gas, wireless, big data, security, drones and industry analyst perspectives. Hope you enjoy this week’s roundup, and as always, tell us what we missed! Energy Six Ways IoT Enables Innovation in the Energy Industry (IT World Canada) The energy industry is learning to use IoT to its advantage. IT World Canada details six ways IoT is enabling innovation and improving overall cost and efficiency for the industry. Yogi Schulz with IT World Canada believes that “Applying these IoT advances to a range of energy industry problems will be a major factor in helping the industry return to profitability in the new, lower commodity price environment through innovation based on better data.” Manufacturing Machine Learning (The Economist) As manufacturing becomes digitized, the industry has to adjust from being a product-focused world to a services market, with smart machines installed on the shop floor. The Economist believes that “For many manufacturers—in Germany and beyond—the principal sticking-point in making this digital leap is often cultural.” Manufacturing’s Digital Future (Industry Week) The digital future of manufacturing will incorporate the data analytics, cloud and many other wireless IoT solutions. Industry Week believes “many companies are leveraging interconnectivity to improve their own factory productivity, the factory-floor blocking and tackling of reducing downtime, cutting costs, reducing cycle time, improving OEE, etc.” Oil and Gas In the Digital Oilfield, “No Wires is a No-Brainer (World Oil) With the digital progression of our world, it seems only fitting we would find IoT in the oilfield. The question we must ask is: “Why, in 2015, has wireless I/O not overtaken hardwired infrastructure as the industry standard throughout the OFS sector?” Big Data Internet of Things Transforming Oil and Gas Operations (RigZone) Analytical movement has increased as the cost of oil continues to drop, therefore forcing the oil industry to gravitate toward more big data and IoT. It has been said, “the amount of data generated by oil and gas operations is starting to explode as real-time information from sensors is being collected at a rate of four milliseconds.” Wireless Tech Darpa’s RadioMap Detects RF Spectrum Congestion (GCN) An interconnected connected wireless world has created congested airways, thus making military communication and intelligence gathering requiring radio frequencies be managed. “RadioMap adds value to existing radios, jammers and other RF electronic equipment used by our military forces in the field,” said John Chapin, DARPA program manager. Big Data The Ethics of Big Data (Tech.Co) Big data has been defined as information that has been either unstructured or multi-structured as way to transform data into value. Once you have given value to the data, it is important to realize who owns the data. Tech.CO says that “when it comes to big data ethics, privacy is not necessarily dead, shared information can still have a reasonable degree of confidentially, but big data can still compromise identity and other information that customers and businesses prefer to be confidential.” Security IoT Security Needs to Stop Being an Afterthought (PCR) In the age of smart homes and smart devices it is time to improve the IoT security across the board. The Internet Society (ISOC) recently released a white paper stating, “the vendors who use IoT should take more responsibility for the security issues that can occur with IoT products.” Drones Robo-Bulldozers Guided By Drones Are Helping Ease Japan’s Labor Shortage (The Verge) Komatsu had to find a way to complete construction projects, as Japan gets closer to the 2020 Olympics. The aging population makes it hard to find anyone able to complete the work. The fix Komatsu has found is to offer a service called Smart Construction where, “a team of robotic vehicles scoops rock and pushes dirt without a human behind the wheel. They are guided in their work by a fleet of drones, which map the area in three dimensions and update the data in real time to track how the massive volumes of soil and cement are moving around the site.” Deforestation: British Firm Developing Tree-Planting Drone to Counter Industrial-Scale Logging (The Independent) A British engineering company is hoping to get international backing for an automated tree planting drone system. The purpose of these drone planting fleet’s, would be not
IIoT Bold Prediction Series Part 4: New Networking Protocol Changes IoT Connectivity
Before we move on to the next prediction in our IIoT Predictions series, let’s take a quick look back at the first three: A major security breach of an industrial SCADA system will bring new focus to IoT security. The government will become heavily involved in the regulation of IoT and IIoT devices. Predictive analytics will alter fundamental IT/OT practices. Part of the difficulty in procuring “predictions” for something like the Internet of Things is that the possibilities are truly endless. We know that “IoT” as a concept will increasingly touch on almost every single facet of our daily lives with each passing month, so part of the excitement is being attuned to the new concepts, technologies and thought leaders that seem to pop up near daily. It is an interesting time to be both a creator and user of technology! Today’s prediction, courtesy of Brad Gilbert, director of product management at FreeWave, continues our path toward the more technical side of the Industrial Internet of Things. We know that the technology will continue to progress, but what about the “internet” side of IoT – the enabler of the comprehensive connectivity we’ve come to expect? Prediction #4: Wireless Networking Protocol will Change the Way We Think about IoT Connectivity 802.11ah is a new wireless networking protocol that has the potential to enable a range of connectivity that was previously deemed improbable to obtain – greater sensor connectivity and the potential for even faster data transmission. It is scheduled to be released in mid-2016, and Brad predicts it will garner quick adoption. Here’s the why behind it: 802.11ah Unifies GHz and sub-GHz bands with a Wi-Fi protocol Reduces the need for protocol conversions and gateways Highly congested 2.4GHz band can now be offloaded to either 5GHz or now 900MHz The essence of these features is that they provide a greater diversity for device enablement by offering more networking and frequency band options. The unification of bands reduces the potential for interference and offloads traffic from the 2.4GHz band that is used for wide-range networking needs. 802.11ah Addresses long range communication and battery operation not met with existing 802.11 standards Much needed for IIoT applications, especially those in remote and hazardous locations Better RF propagation than 2.4GHz or 5GHz frequency bands In conjunction with band unification, the new protocol will enable the extension of high-speed connectivity to rural areas without overloading cell tower traffic. It will allow devices to use less battery power by predetermining wake and doze times, and by incorporating relay access points, it will allow networking stations to transmit data more quickly, reducing the overall wake time. Chipset availability The availability of chipsets (specifically SoC technology) will enhance data transmission even further by better managing integrated components and data flow to and from different networks and IoT enabled devices. What’s next? So far, most IIoT devices have been built with traditional band usage in mind. Introducing a new and efficient networking protocol will allow for a greater diversification of device capabilities, as well as a proliferation of sensor networks at a scale that would be unachievable with current standards.
IIoT Bold Prediction Series Part 3: Predictive Analytics Alters Fundamental IT/OT Practices
So far, our series of IIoT Bold Predictions for 2016 has focused on the concepts of IIoT security and government’s regulatory role in the development of IoT and IIoT devices. Today, we’re changing gears a bit, with a prediction from Scott Allen, FreeWave’s CMO, which focuses on the implementation of IIoT technology into big data practices to create real-time, data-driven intelligence. Prediction #3: Predictive Analytics Alters Fundamental IT/OT Practices Predictive analytics will change the nature of industrial communication systems and networks significantly over the next five years. Certain industrial sectors have long utilized machine-to-machine (M2M) technology, like manufacturing, utilities, and oil and gas, as the backbone to operations technology. However, as IIoT communication technology continues to improve at a rapid pace, these industries will begin implementing tech and business practices designed to create data synergy that will ultimately provide predictive analytics for better decision making. There are two elements at work that will push predictive analytics to the forefront of industrial communication systems. The first is the advancement of technology. Big data companies are making serious progress with comparing data-at-rest with data-in-motion as a strong basis for predicting outcomes with maximum accuracy. As the network infrastructure advances at the access layer in ways that allow analytic applications to be executed locally while communicating globally this trend will do nothing but accelerate. The second element that will drive change is the retiring or soon to be retiring workforce that drove the implementation and use of SCADA networks. This will create a knowledge gap that will require new technology to fill – and predictive analytics will be the one that fills that gap. Although an aging workforce is not unique to the IIoT sector, the transition will be pronounced and could, without incorporating predictive analytics practices, be accompanied by some significant growing pains. Looking Ahead Sensor-2-Server (S2S) technology will begin to ease the synergy between IIoT technology and big data. Ensuring accurate data transmission, collection and analysis in critical industries is an important step along the path to a connected world. As S2S technology proliferates, companies will see a significant impact on IT and OT practices, along with the ability to converge those two silos into more efficient and streamlined decision-making.
Announcing the 2016 IIoT Bold Prediction Series!
The year 2015 is soon coming to an end as the year 2016 looks to be ushering in exciting new ways in which the Internet of Things (IoT) is changing our way of life. It’s easy to see these transformations taking shape on the consumer side (home automation, smart appliances, connected cars, personal computers, smart devices, etc.), but what will 2016 hold for the Industrial IoT (IIoT) space? (Note: Go here for a quick rundown on the difference between consumer IoT and industrial IoT) 2016 IIoT Bold Prediction Series As stated in our introductory blog post (Are We All on the Same Industrial IoT WaveLength?), we at FreeWave Technologies are thrilled for the future of the IIoT and what it means for the entire business ecosystem. That is why we are excited to present the “connected world” community with a bold prediction in IIoT each day this week – aptly named the 2016 IIoT Bold Prediction Series! We of course encourage everyone to contribute your perspectives and experiences – whether in response to our predictions or a submission of your own – to help advance the dialogue around the emergence of the industrial internet. Our first bold prediction in the series comes from Glenn Longley, Regional Manager of Energy Markets at FreeWave: Prediction #1: Major Security Breach of Industrial SCADA System Brings New Focus to IoT According to Longley, “There will be a major security breach of an industrial SCADA system in 2016, which will drive industrial organizations to shift more of a focus on IoT and newer, more secure communication systems.” If you may not already know, cyber attacks against supervisory control and data acquisition (SCADA) systems are not new. In fact, Homeland Security Magazinereported earlier this year that “Cyber attacks against industrial targets—including power plants, factories and refineries—increased 100 percent in the past year, according to a new study conducted by computer technology company Dell.” Additionally, IT World Canada reported on a new InfoSec survey by the SANS Institute in 2015 where, “Both the degree of uncertainty and the rising number of known incidents are red flags calling for the dedication of greater resources to monitoring, detecting and analyzing anomalous activity in control system networks.” The survey also found that only 65 percent said vendor qualification of security technologies and solutions to be either highly important or mandatory. So with a proliferation of new cyber attacks seemingly happening more frequently, Longley explains how this widespread issue will impact IoT adoption in industrial businesses in the coming years: “Each company is different in how it handles the influx of IoT and the resulting IT/ OT convergence. With the merging/blending of Information Technology (IT) and Operations Technology (OT), the firewall that separates the two becomes more complicated and less well-defined. Traditionally, each was a separate entity; however, with IP-enabled devices and blending of technologies in enterprise networks, that dividing line becomes less clear. IT and OT professionals themselves might put a different emphasis on security, but in 2016, the two will need to come together (more than ever before) to prioritize security in their quest to create end points for all of their field assets. Therefore, security will ultimately be the limiting factor on how much IIoT is deployed.”
IIoT Top News: Manufacturing Today and Tomorrow
The age of manufacturing is moving past the dusty, oversized, broken-down warehouse located on the edge of town and into industrial 4.0. This new technological revolution is changing the way manufacturing operates within the digital sphere. Nowadays, manufacturers can track production status, machine functionality and operational flow with sensors, automation and wireless IIoT solutions. That’s why this week’s top news is dedicated to manufacturing of today and tomorrow, realizing this industry is evolving with the digital revolution. This is an exciting time for manufacturing, with more innovation integration happening across the board than in the last twenty years. As the IIoT starts to take center stage in many shop floors, new digital upgrades will require a new plan of action to deploy wireless pilot projects for automation and control. Now with the rise of smart machines in manufacturing, this industry has to shift from a product oriented world to a services market. Sensors that tell you why it is not working or machines ordering products independently when supplies run low are all examples of this new industry 4.0 revolution in action. Naturally this technological movement began in Germany back in 2011, where twenty-two percent of their GDP comes from manufacturing, this compared to only twelve percent of the GDP in the US. Although, a recent report by Cisco finds that the majority of manufacturers are not capitalizing on this digital push. It is true most manufacturers do see the importance of the digital transformation on their shop floors, but the problem comes with the implementation of those new technologies without disrupting the current production process. As manufacturers digitize, it is vital to first find the correct infrastructure to implement the IIoT, and then to adapt a new model to incorporate the technology to the main business plan. So what does the future hold for manufacturing? As some companies adapt to this digital age, it is true manufacturing can now create digital prototypes, use 3D printers and operate remotely with sensors and wireless monitoring. Being able to collect data in real-time utilizing cloud-based IIoT solutions will be the key to succeeding in manufacturing going forward. Yet, according to Information Age 2016 top predictions, “Manufacturers will have to start thinking and acting more like software companies, leveraging the software applications they build into their products as a driver to reduce manufacturing costs, increase product innovation, and capture new revenue streams.” Furthermore, IoT, data analytics, cloud, and other wireless technologies have the potential to drastically improve manufacturing. The trick, as we march to the beat of this new technological revolution, will be to look at examples of how early adaptors have grasped the IIoT. It’s understandable with everyone shouting about the IIoT, it is easy to get overwhelmed. So stop thinking about all things connected and focus on what infrastructure will support your growing digital needs on the shop floor, and then your plan of action will seem a bit more manageable. Hope you enjoy this week’s reading. As always, tell us what we missed! Enabling Manufacturing Transformation with the IIoT (PTC) This push for IIoT is transforming the way manufacturing operates and functions as a whole. PTC suggests that, “As these innovations and pilot projects begin to emerge as broadly deployed best practices, the industry will start to see the emergence of business model transformation and the visions of Industries 4.0 and Smart Manufacturing will start to become a reality.” Machine Learning (The Economist) As manufacturing becomes digitized, the industry has to adjust from being a product focused world to a services market, with smart machines installed on the shop floor. The Economist believes that, “For many manufacturers—in Germany and beyond—the principal sticking-point in making this digital leap is often cultural.” Survey: Manufacturers’ Digital, Service Capabilities Lagging (Manufacturing.net) Manufacturers see the need for adding more digital components to the shop floor, but recent CISCO report finds that many manufacturers are still not capitalizing fully on the IIoT. “One challenge is on the technology side, making sure that the right infrastructure is provided,” said Dirk Slama of Bosch Software Innovations. “The second challenge I would see is more on the organizational level, to make sure that you somehow help your organization move towards these new business models.” The Factory Future (Manufacturing Today) The future of manufacturing will depend on the industries abilities to incorporate real-time results with their wireless IIoT solutions. Manufacturing Today has stated that, “More manufacturing will need to be able to harness all that data via the cloud to meet demands from customers and potentially legislators to fully track the entire lifecycle of their products—from creation to disposal of ideally recycling.” Manufacturing’s Digital Future (Industry Week) The digital future of manufacturing will incorporate the data analytics, cloud and many other wireless IoT solutions. Industry Week believes that, “Many companies are leveraging interconnectivity to improve their own factory productivity, the factory-floor blocking and tackling of reducing downtime, cutting costs, reducing cycle time, improving OEE, etc.
Today’s IIoT Security Challenges
For decades, Supervisory Control and Data Acquisition (SCADA) systems have played a significant role in industrial operations. Industries like oil and gas, electric power/smart grid, agriculture and utilities have implemented SCADA systems and networks to collect data and automate processes, and are always looking to automation systems for more effective ways to operate. The ability to collect more data from geographically dispersed field assets in remote locations has driven the need for enhanced communication technologies. With the emergence of continuously improving wireless machine-to-machine (M2M) technologies, networks have more access to data points than ever before. The number of sensors and data points collected will continue to rise dramatically with improved connectivity. This collected data helps operators improve operational decisions, save manpower and, in many instances, keep employees safe by avoiding dangerous environments. Today, industrial network operators are increasingly implementing end-to-end Internet Protocol (IP) connectivity or the Internet of Things (IoT), enabling more capabilities at the edge of these networks. This does not make SCADA systems obsolete by any means; it opens the door to greater possibilities of enabling new applications and analytics with every single data point being captured in the system. So What’s the Security Tradeoff? There are many implications for the concept of a completely connected enterprise in terms of network security. Critical infrastructure projects are only as reliable and secure as the technology serving them. Security, therefore, will ultimately be the limiting factor on how much IoT technology is deployed. With security, the traditional trade-off is either “easy to use” or “secure”— but not both. We often consider a third tradeoff as well of features, though in most cases, operators are not willing to trade off features, but it is certainly part of the equation. An operator striving for an Industrial IoT (IIoT) network must look at SCADA security, the convergence of Operations Technology (OT) and Information Technology (IT), and make a thorough assessment of what will allow them to achieve a secure data communications network. Some of the top security challenges for the IIoT today include: With more data being transported than ever before, it’s important not only to secure assets, but to secure the communication link itself. Traditionally, SCADA systems have been on the outside of a firewall from the corporate IT network. Newer SCADA systems that use Ethernet devices are more security focused with measures such as VPN, secure sockets, encryption and dedicated log-ins on the devices. One Final Thought There are many benefits to the concept of a completely connected IoT system, but this also implies more crossover between IT and OT systems. Companies need to prioritize security in their quest to create end points for all of their field assets. Some industries, like the smart grid, are already experiencing mandates that ensure a more cyber-secure network. With others, however, it is still up to the organization to make security a top priority.
