Network Management Solutions for IIoT

The shift towards digital technology solutions and the rise of the industrial Internet of Things (IIoT) have transformed operations for many organizations. Currently, there are a number of wireless communication solutions available that are specifically designed for IIoT, M2M and SCADA networks. These technologies monitor, collect and transfer critical data in challenging environments to support mission critical use cases. As technology continues to advance, Sensor-to-Server (S2S) technologies have emerged to support advanced data practices, such as predictive analytics. IIoT has not only increased the number of devices in the field, but has also brought the OT and IT departments closer together. This convergence is challenging for many businesses as they look to find technology that will meet evolving demands. IT, for example, needs better field visibility as industrial networks become more connected every day. This need has driven a strong demand for detailed, real-time information solutions that will support IT network operations. Having a network management system (NMS) at the access layer helps meet those needs and companies like E2E have begun to offer NMS solutions specifically for IIoT, M2M and SCADA networks. These networking solutions help overcome some of the major visibility issues from an IT perspective and are suitable for operation in challenging environments . FreeWave’s NMS Partnership FreeWave recently announced a new technology partnership with E2E Technologies. E2E’s Stingray Network Management System (NMS) will support FreeWave’s WavePro™ wireless communication solutions. Stingray is optimizable for IT professionals looking to manage individual components of a limited IoT or M2M communications system within a larger IT network management framework. Companies in energy, utilities, municipalities, government, oil and gas, and more will benefit from this solution as they now have a technology solution designed to help bridge the IT/OT convergence gap.

Outdoor Wi-Fi Solution in Your Future?

Is an outdoor Wi-Fi solution in your future? Modern Sensor-to-Server (S2S) communication networks call for high-speed solutions that support massive amounts of data collection, control and transport. Today, industrial organizations are experiencing high demand for voice, video, data and sensor (VVDS) information in wireless outdoor networks. The challenge is finding Wi-Fi networks that can ensure connectivity in outdoor environments that are often volatile and unpredictable. The good news — robust, secure outdoor Wi-Fi hotspot platforms designed for shorthaul communications enable a variety of data collection options that can withstand the harshest outside elements. Reputable outdoor Wi-Fi networks can leverage multiple networking protocols and services. They are designed to meet the needs of enterprise-scale communications across a wide range of critical infrastructure industries like oil and gas, utilities, mining, municipalities, perimeter security, disaster recovery, and outdoor recreation. Keep in mind this is just snapshot of the industries that can benefit from Wi-Fi – there are numerous applications in just about any outdoor Internet of Things (IoT) network. Outdoor Wi-Fi | Real-life Scenario Recently, an electric power company based out of North Carolina needed to transition the Direct Load Control (DLC) switches for its residential load management program. The transition affected 275 air conditioning (AC) units across two rooftops at a residential senior living community. WavePro (WP201) shorthaul point-to-point and Wi-Fi platform units were used to enable the transition. In this instance, Wi-Fi was leveraged to increase the Load Management System’s (LMS) effectiveness by creating two-way communications to switch monitoring and control, instead of the previous one-way paging system that was in place. A local internet service provided communications from the LMS to a rooftop Internet Point of Presence (PoP). Additional solutions, including Wi-Fi enabled controllers and Wi-Fi access points (four WavePro Units) were selected for the installation.  The WavePro units were configured to solve three communication requirements in the Wi-Fi network: wireless communications between the controllers and a WP201; wireless communications between the four WP201s on the two rooftops; and communication between one WP201 and the single Internet PoP. The completed Wi-Fi solution enabled real-time communication between the LMS and each of the HVAC controllers on the two residential towers. The energy company can now effectively manage and confirm power curtailment events in real time. Win a WavePro Network You have a chance to win your own WavePro high-speed outdoor Wi-Fi network.

Who Needs Rugged, Outdoor Wi-Fi Networks?

When we think about Wi-Fi, we tend to lean towards the idea of connections that allow us to access our mobile devices. With a Wi-Fi connection we can stream videos, access our apps, check email, work and basically manage our digital lives. In non-traditional settings, the need for outdoor Wi-Fi connectivity is increasing, but it is accompanied by some unique challenges. Outdoor Wi-Fi  Connectivity Industries that operate mostly outdoors are finding a greater need for Wi-Fi connectivity. Campgrounds are providing Wi-Fi as both an amenity and as a tracking and booking tool for managers and campers alike. Golf courses have deployed industrial-scale Wi-Fi networks to monitor irrigation, golfers and other assets throughout a course, and marinas are using Wi-Fi networks for both communication and vessel management needs. There has also been a strong uptick in the use of industrial Wi-Fi networking for security programs and disaster response. Companies can use  high-speed Voice, Video, Data and Sensor (VVDS) data transport as building blocks for a security network capable of real-time monitoring. These Wi-Fi solutions are especially ideal for video monitoring, as they provide the bandwidth necessary to transport large amounts of data. Disaster response has also been an ideal application for industrial-scale Wi-Fi. Often times, cell networks can get knocked out during environmental disasters, effectively eliminating a critical component for communication. Today, organizations can deploy these Wi-Fi platforms on vehicles or other response assets that can enable communications in emergency or disaster situations. For any industry with outdoor operations, assets will be exposed to the worst natural elements – extreme heat, freezing temperatures, heavy snow, strong wind, dust storms and more. The challenge is finding a shorthaul, Wi-Fi solution that is rugged and secure enough to withstand the elements, but also advanced enough to enable new types of high-speed, high throughput application solutions. Rugged Wi-Fi Communication Solutions There are solutions designed for robust, secure transport of VVDS information for the edge devices in industrial communication networks. These rugged, shorthaul communication networks are specifically designed for outdoor Wi-Fi connectivity and have proven reliability in extreme environmental conditions. These types of solutions are ideal for oil and gas, utilities, mining, power plants, municipalities, disaster recovery or any other type of industrial applications. They also suit innovative deployments at golf courses, marinas, campgrounds and other settings that require outdoor Wi-Fi connectivity.

All Aboard the IoT Railway

In many parts of the world, rail represents a major component of infrastructure – for the transportation of both humans and goods. In fact, railways are critical to some of the major industries like oil and gas, agriculture, and food refrigeration/transport. Much like those industries have, over the years, adopted automated, machine-to-machine (M2M) technology, railroads have similarly deployed more advanced technology over the years as well. Railways began the “automation” process by adding Automatic Equipment Identification (AEI) tags back as early as 1989. These sensors track the specific item tagged, but they have no way of knowing how the train is operating as a whole. Companies also began deploying RFID tags to track goods being transported along the different lines. The AEI sensors could provide information on the rail car and would interact with the various readers along the route. The additional sensors were great for location awareness, but still lacked the ability to monitor all the moving parts on the train. Still, with these two initial steps, the early stages of Internet of Things (IoT) technology began to come into focus for the railroad industry. IoT Railway Solution The rail industry needed a way to develop a more intelligent infrastructure that enabled Sensor-2-Server (S2S) data transmission via a network of Wi-Fi and voice, video, data and sensor control systems. Due to the massive amount of data collection a system like this would develop, railways are now developing a fully digital service that is directed toward centralized facilities capable of aggregating data from different sources and streams and analyzing that data in real-time. For instance, today, railroad sensors monitor everything from rail car and locomotive health, to track conditions, air temperatures, stress gauges and component conditions. Having a centralized system allows operators to take that data being collected  and use it to develop predictive maintenance practices; that is, the ability to predict when a section of rail or a specific component is in need of repair or near failure. Predictive maintenance is only one component of IoT integration for the rail industry, but it is one that can potentially transform practices across the board, ultimately saving companies time and money – valuable elements for an industry centered on logistics. Across the pond, the University of Huddersfield’s Institute of Railway Research has found that tracks can be monitored with inexpensive sensors set to operate by the vibrations of oncoming trains. According to the research, the sensors will still operate if one of the sensors is damaged, because of a built-in fail-safe. These sensors are projected to detect both approaching trains and the real-time conditions of the track. Adding an IoT network to trains can help improve safety and efficiency with traffic congestion, monitoring and control speed. Even the non-critical business operations have the ability to operate efficiently on the train with the help of modern sensors. Beyond rail sensor networks, there is also the consideration of the passengers as well. If railroads can implement Wi-Fi networks on passenger cars, passengers will be able to receive travel updates, railroad companies can develop specific apps for their travelers, and riders can enjoy the utility of internet in areas that previously lacked service. Although rail remains largely an industrial consideration in the United States, the growth of IoT technology available to the greater industry bodes well for the continued development of this infrastructure around the world.

Smart Golf Courses = A Hole in One!

Smart golf courses are coming to a green near you. A modern day golf course requires many things, including real-time monitoring for irrigation and pump systems, automated vehicle location capabilities for carts and players, and the ability to provide employees with the internet connectivity necessary to manage the sprawls of the course itself. As a result, golf course managers are turning toward some of the cutting edge Internet of Things solutions on the market to meet that demand. As far as preferred pastimes go, golf ranks relatively highly for young and old alike. In fact, according to the National Golf Foundation, there are more than 15,000 18-hole golf courses throughout the United States. The American Society of Golf Course Architects estimates that a full-size golf course would need up to 200 acres of usable land, which means that courses in the U.S. take up at least three million acres. By comparison, that’s nearly three times the size of the Grand Canyon National Park. With that in mind, the management of golf courses is a minor feat in advanced agricultural practices and logistics. Smart Golf Course Solution For one Colorado course, the smart golf course solution to its connectivity conundrum lay in the deployment of an industrial-scale Wi-Fi network capable of handling communication, accessibility and maintenance needs. Course managers selected a dual-band, mesh networking platform that provides Wi-Fi coverage in the necessary areas, and with the help of the provider, set up a network that strategically positioned the platforms so that devices and sensors could remain connected via the mesh networking capabilities as they moved from place to place. However, any outdoor Wi-Fi network does come along with its challenges. For example, another factor that golf courses need to consider when determining the best networking option is the weather. Although most courses are situated in areas that don’t typically draw extremely cold temperatures, many are consistently faced with hot or humid climates that can knock networks offline as the communication platforms succumb to the elements. The last thing any course manager wants is to have their communication network fail, especially if that impacts their customer experience. Adopting ruggedized outdoor networking and communications solutions means being confident that the platforms are designed to function without failure – even in areas with extreme weather events or consistently hot temperatures. Additionally, to ensure that the data being collected from irrigation and pump systems is being delivered in real-time allows grounds teams to monitor and predict when the systems are in need of maintenance, or when certain areas of the course are in greater need of water than others, for instance. Today, grounds crews can track this data via handheld devices that can quickly aggregate and analyze data, rather than spend time manually checking each individual service point. Although modern golf courses often look pristine to players and observers alike, upkeep and ongoing service requires constant attention. As these courses begin to deploy more advanced networking systems to become smart in its communication and monitoring practices, the ability for courses to streamline workflow and maintenance needs will only continue to grow.

Behind the Scenes: Airports Across the Country

Many of us have been in airports around the country a lot lately. Summer vacations are a time when families converge at our local airports, anxious to spend time with loved ones and get to their destinations for fun, relaxation and adventure. However, we tend to take for granted all that goes into running our airports, along with the safety and security required to ensure the smooth operation each airport requires. Plus, we generally only think about what is happening inside the airports, but the truth of the matter is, there is potentially more activity happening outside of the airport at any given time. From aircraft maintenance crews and air traffic controllers to airfreight handlers and runway security personnel, there is a slew of machines and people conducting airport operations outdoors that need to be coordinated and as efficient as possible. According to a 2010 report by the Bureau of Transportation Statistics, a total of 631,939,829 passengers boarded domestic flights in the United States that year. This averages to 1.73 million passengers flying per day. It’s mind-boggling to think how this number has increased since that time as it’s clear that general aviation airports of all sizes are an integral part of our National Aviation System. Many airports have aging facilities, shifting demands to accommodate the changes in the general aviation industry, and diminishing revenue sources. These trends coupled with limited staff and budgets have made it difficult to properly maintain the facilities beyond responding to immediate needs. Automator of Airports The automation of processes and industrial communications can help. Setting up an outdoor industrial wi-fi network is one way field managers at airports can ease the burden of maintaining a safe and efficient infrastructure. For instance, establishing a hardened and ruggedized commercial-grade wi-fi network around the perimeter of an airport not only creates a safe and secure enclosed zone, but, also provides a way for maintenance crews to monitor and ensure the overall outdoor field operations of the airport facility. This can be easily achieved through resilient wireless networks because they allow for easy and relatively inexpensive modification as outdoor airport infrastructures and policies change (which can be frequent). In addition, besides obvious benefits to airport maintenance crews, there are indeed FAA requirementsthat need to be adhered to for compliance – making it even more imperative that airport facility personnel find more effective ways of ensuring proper airport operations and safety procedures are maintained at all times. Some examples of how outdoor wi-fi networks can assist in a smoother, more automated airport infrastructure include: Establishing a communications link with all airport maintenance crew through VoIP, video and data so that all personnel are able to communicate with one another and send immediate notifications if/when needed – saving time, effort and money. Adhering to FAA mandates which require personnel to provide reports on outdoor lighting, runways, vehicles and the overall airport infrastructure three times per day. Great efficiencies can be obtained through automating these various tasks reducing the amount of time and labor needed to maintain, monitor and report these things. Installing communication devices on airport maintenance vehicles connects all of them so that personnel can notify proper authorities of outages through their tablets versus manually having to inform supervisors that action needs to be taken. These are just a few of the ways an industrial outdoor wi-fi network can help airports maintain a safe, secure and well-functioning infrastructure. So what will the future airports look like and how will they operate? If the current IoT landscape has shown us anything its that any manual process or operation that can be automated through the use of machines or smart devices eventually will be (automated). As airport field operations continue to be held to higher standards and increasingly rigid regulations, the faster they can adapt to the pressures of an on-demand economy, the better.

Critical (Outdoor) IoT Applications Need Robust Connectivity

It’s safe to assume that the majority of all Internet of Things (IoT) devices operate near large populations of people. Of course, right? This is where the action happens – smart devices, smart cars, smart infrastructure, smart cities, etc. Plus, the cost of getting “internet-connected” in these areas is relatively low – public access to Wi-Fi is becoming widely available, cellular coverage is blanketed over cities, etc. But what about the devices out in the middle of nowhere? The industrial technology that integrates and communicates with heavy machinery that isn’t always “IP connected,” operating in locations not only hard to reach, but often exposed harsh weather. The fact remains, this is where IoT connectivity is potentially most challenging to enable, but also perhaps the most important to have. Why? Because these numerous assets help deliver the lifeblood for our critical infrastructures – electricity, water, energy, etc. Without these legacy and geographically dispersed machines, a smart world may never exist. But let’s back up for a second and squash any misconceptions about the “industrial” connectivity picture we’re painting above. Take this excerpt from Varun Nagaraj in a past O’Reilly Radar article: “… unlike most consumer IoT scenarios, which involve digital devices that already have IP support built in or that can be IP enabled easily, typical IIoT scenarios involve pre-IP legacy devices. And unfortunately, IP enablement isn’t free. Industrial device owners need a direct economic benefit to justify IP enabling their non-IP devices. Alternatively, they need a way to gain the benefits of IP without giving up their investments in their existing industrial devices — that is, without stranding these valuable industrial assets. Rather than seeing industrial device owners as barriers to progress, we should be looking for ways to help industrial devices become as connected as appropriate — for example, for improved peer-to-peer operation and to contribute their important small data to the larger big-data picture of the IoT.” It sounds like the opportunity ahead for the industrial IoT is to  provide industrial devices and machines with an easy migration path to internet connectivity by creatively addressing its constraints (outdated protocols, legacy equipment, the need for both wired and wireless connections, etc.) and enabling new abilities for the organization. Let’s look at an example of how this industrial IoT transformation is happening. Voice, Video, Data & Sensors Imagine you are a technician from a power plant in an developing part of the world with lots of desert terrain. The company you work for provides power to an entire region of people, which is difficult considering the power plant location is in an extremely remote location facing constant sand blasts and extreme temperatures. The reliance your company places on the industrial devices being used to monitor and control all facets of the power plant itself is paramount. If they fail, the plant fails and your customers are without power. This is where reliable, outdoor IoT connectivity is a must: With a plethora of machinery and personnel onsite, you need a self-healing Wi-Fi mesh network over the entire power plant so that internet connections aren’t lost mid-operation. Because the traditional phone-line system doesn’t extend to the remote location of the power plant, and cell coverage is weak, the company requires Voice over IP (VoIP) communications. Also, because there’s no physical hardware involved, personnel never needs to worry about maintenance, repairs or upgrades. The company wants to ensure no malfeasance takes place onsite, especially due to the mission-critical nature of the power plant. Therefore, security camera control and video transport is required back to a central monitoring center.  Power plants require cooling applications to ensure the integrity and safety of the power generation taking place. The company requires Supervisory Control and Data Acquisition (SCADA) networking for monitoring the quality of the inbound water being used to cool the equipment. The company wants to provide visibility to its customers in how much energy they are consuming. This requires Advanced Metering Infrastructure (AMI) backhaul networking to help manage the energy consumption taking place within the smart grid. Since the power plant is in a remote location, there is only one tiny village nearby being used by the families and workers at the power plant. The company wants to provide a 

Remote Wi-Fi: Enabling Wireless Video Transport

(Image courtesy Flickr Creative Commons) The topic is not new, but it is increasingly common in conversations with customers and potential users of wireless networks for M2M and IIoT applications. In fact, this topic now occurs in almost every conversation regarding networks and their wireless video transmission capabilities. Our topic is the transport of video and the applications it enables. As reference, a few areas where wireless video is being used are: Security operations, such as facility assess control and perimeter monitoring Work safety to monitor hazardous areas Deterrence of vandalism and theft Process monitoring for improved quality and efficiency For these video integrated systems, they perform several functions: Capture video of the area or process being monitored Transport the video stream to the video analytics, which typically resides in the enterprise network and not at the remote site with the video camera Analysis of the video stream to derive actionable information or data from the real-time feed, and Act upon the information or data extracted from the video where the system may or may not be collocated with the video camera. High-speed wireless networks are well suited for transporting data from remote sites to centralized locations, and again transporting information from the centralized location to remote or other sites where it is acted upon. These high-speed networks require high data rates, low latency and quality of services (QoS) capabilities. Application Examples An example of an integrated wireless video system employing a high-speed wireless network is remote facility access control. The video stream is transported from a remote site to the analytics engine located in the enterprise network where facial or license plate recognition is performed on the video stream. If the person or vehicle is to be on site, the on-site assess control system locks or unlocks a gate or door. In this example, the integrated system has the video source and assess the control system collocated. Another example is improving worker safety through transporting video and analytics where the analytics detects worker presence and activity. If the activity stops, the worker can be contacted through an emergency management system. If the worker does not respond to the contact, an emergency response team can be dispatched. In this example, video transported from the remote site is analyzed and drives inputs into emergency response systems that are not collocated. Video analytics is promising with a wide range of possible applications. However, it is the wireless high-speed network that makes these services viable and cost effective since the wireless network has the bandwidth to be used for multiple applications (voice, video, data and sensor) across multiple departments within the enterprise.

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?
