Organizational alignment is a key driver of Internet of Things solutions.
“One of the biggest challenges for organizations today? Alignment goals, measures, performance across functional groups.” - Maha Muzumdar, Oracle

Successful IoT strategies and systems consider the end result first.
“People aren’t buying the tools, they’re buying the end results. Like the saying, ‘we don’t want the hammer and nails we want the picture on the wall.'” - Matt Meshulam, TempoIQ

It’s time for new systems in the enterprise, not just for operational efficiencies, but for the productivity of employees.
“Legacy Tools are failing us…” - Beverly Macy, UCLA

We took the stage and shared how the systems that our customers like Clean Hands Safe Hands, ATEK and Heat Seek have implemented can not only revolutionize customer service, but put data in the hands of employees to set them up for success like never before. As technologists and business leaders, it’s our responsibility to utilize technology to equip great people to do their jobs even better. You can learn about more living Internet of Things solutions here.

Keep an eye out for a recap of our session, we’ll post it here soon.

Wireless Technology Driving Business Transformation in the Oil & Gas Industry

Posted on:

As the demand for oil and gas increases, reduction in operating and maintenance costs and an increase in reliability are top priorities for the industry. However, that is easier said than done when you’re talking about assets deployed in harsh environmental conditions and widespread, remote locations. Even minutes of production downtime can result in hundreds of thousands of dollars lost. Ensuring that production machinery and other critical equipment downtime is minimized not only reduces operating and maintenance costs, but also increases production revenue and improves worker safety.Screen Shot 2015-04-02 at 12.29.50 PM

Oil and gas companies will benefit by moving away from a reactive analog maintenance model where action isn’t taken until a field operations team arrives at the location and identifies the asset is no longer functioning, resulting in unplanned downtime and lost revenue. Many companies have migrated to a proactive (scheduled) maintenance model, which is characterized by maintenance being performed at manufacturer-recommended intervals. This philosophy is actually the most expensive to follow because components could be unnecessarily overhauled or replaced. In addition, assets can and will still fail between maintenance cycles.

preventative maintenance model on the other hand, brings assets and data into business operations to enable companies to remotely monitor, control and identify problems. Being able to predict failures and maintenance requirements, you can better forecast and schedule maintenance activities, which reduces operational and maintenance costs.

With our XLR Pro long-range wireless radios, industrial grade Transport WR21 cellular routers and Digi Remote Manger, companies can quickly deploy a comprehensive global connectivity model today. You can seamlessly connect your assets, gather and integrate data to better control those assets, and remotely manage the network devices for security compliance and system updating. This kind of solution results in:

  • Connected assets and their data have increased visibility across an entire organization.
  • A proactive approach to maintenance whereby issues are resolved before they even occur
  • Field service operations teams are empowered by a rich set of device data and information to begin troubleshooting issues. This includes not only the real-time status of mission critical equipment, but also historical data points for trending and long term analysis
  • Deployments and truck rolls are made on a needs-based approach, which manages costs more effectively and positively impacts the bottom-line.

How We Built a 4G LTE Connected Digital Signage Solution

Posted on:

We’re getting settled back in after an eventful few days at Digital Signage Expo. It was our first time at the event and we had a blast! Here at Digi, we mainly focus on the connectivity side of things whether it’s RF modules or a cellular router– that’s our expertise. But, in a digital signage solution, there are so many elements that come into play.

For this special event, we wanted to make sure we had a digital signage demo ready to go and we didn’t have much time to put it together. With some extremely helpful advice and easy-to-use tools we were able to get it up and running in less than a week (thanks to Amazon Prime overnight shipping).

PeerlessandAndrew (2)

How We Did It
Here are the basic elements of the demo. First we needed an enclosure– something that we could mount a big ol’ monitor to. Our friends at Peerless-AV hooked us up. Their kiosk gave us an enclosure for not only the screen, but also the mini PC, TransPort cellular router, and other accessories like antennas and power supplies.

Screen Shot 2015-02-25 at 2.08.33 PM

So now that we had all the gear hooked up and ready to go, we needed to figure out what we wanted to display on the screen. Screenfeed paid us a visit and set us up with some live RSS feeds.

These feeds allow us to send out fresh, new content to the display. Specifically, we had live financial data, major headlines of the day, and most importantly…weather updates. Another crucial aspect of serving up content to our display was the software to manage the images and RSS feeds.

Using our Wondersign free trial we plugged in our RSS feeds and .jpgs and had our screen displaying content in under an hour. Here’s a quick video that walks you through the display live on the DSE show floor!


There are many distinct advantages of delivering content via 4G LTE. For one, you get a high bandwidth connection that doesn’t need existing infrastructure like Ethernet or Wi-Fi, which offers the flexibility to deploy signage anywhere with network coverage. 4G LTE also provides a secure connection and the ability to easily manage a large deployment of devices via the cloud. This is just a demo, but many of Digi’s customers have realized the value of cellular connected signage. Learn how Monster Media is using cellular technology out in the field.

Cellular Connections You Never Knew Existed

Posted on:

You drive into a gas station and notice the LED sign that reads how high the Powerball® is this week. You pull up to the pump and make a mental note to buy a ticket. As you wait for your tank to fill, the screen on top of the pump shares today’s weather and a few specials you can find inside. Then, you walk into the gas station to buy that lottery ticket. The lottery register greets your purchase, and you’re ready to move on with your day—hopefully with the winning ticket in your pocket.

During your time at the gas station did you ever consider how many wireless connections were at work? Probably not.

When you do think of wireless connections, it’s likely Wi-Fi hotspots or smartphone payment tools like Square that come to mind. However, there are many little-known and less visible ways that retailers and service providers use 4G LTE connections to make operations work. From digital signs to lottery terminals, wireless connections help make our world go around in ways you may have never imagined. They’re all working to create an experience for you as a customer and a return for merchants and manufacturers. Let’s dive deeper into a few applications where invisible wireless “workers” are impacting your retail environment.

Lottery TerminalsScreen Shot 2014-07-15 at 10.20.07 AM

Tucked behind the counter at your local convenience store, you’ll find that signature register or lottery terminal. You might just think of this as the machine that prints your easy-pick, but if the terminal gets disconnected the vendor is on the hook for much more than your ticket alone. It’s up to the store to ensure the machine is up and running at all times, so no revenue is lost. In fact, the damage can add up to more than all of the numbers on your ticket combined. For that reason, many of these terminals are connected to a datacenter with both a satellite and a 3G or 4G LTE connection.

Although the vast majority of lottery revenue is returned to players in prize money, the remainder pays for the operation of the lottery—including paying the retailer for hosting the lottery terminal. More importantly, the lottery also contributes hundreds of millions of dollars to state budgets. In 2012 in the state of Minnesota alone, $124M was contributed to funds such as environment and natural resources, game and fish, metropolitan parks and trails, zoos and infrastructure. The State Gaming Commission authorizes one vendor to operate their entire statewide lottery. In exchange for that level of access, the commission holds the gaming contractor accountable to maintain a high service level. If terminals aren’t able to communicate, the gaming contractor can be held accountable for damages of $20 per minute or more—per terminal.

Tire Air Vendingairtire

Hopefully, it’s your lucky day and you have a winning ticket in your pocket, but in the case that your day started out rough and your dealing with a flat tire, you can pull up next to an air-pump kiosk. Don’t have change? No problem. Swipe your credit card and the transaction is sent over a cellular connection.

While the connection makes payment collection more convenient for you, there’s a lot more at stake than meets the eye. In the past, technicians had to phisically visit every single machine to empty the coin bin– whether it was full or not. Not, a cellular connection enables the machine to report back how full the coin bin is, along with the health of the machine. This saves the manufacturer millions of dollars in employee and transportation costs, and it ensures all machines are up and running properly creating even more revenue– not to mention better customer service for the retail operations that host these machines.

In many cases, manufacturers experience a loss between money collection and revenue that makes it back to the business. In one example, receipt reconciliation loss was $11M per year. In the first year, a connection improved that loss by 80%, providing a bottom line impact of $8.8M. Lack of pick-up optimization (sending someone to collect the money after the machine is already too full to accept more coins) created an annual loss of $5.5M; that was improved by 50% and impacted the bottom line by almost $3M. Downtime, which caused the most significant loss at $12M per year, was improved by 30%. With numbers like these, an air vendor could easily double the value of the system in one year alone.

Charging Stations & Digital Signs

Have you ever charged your mobile phone while enjoying a cup of coffee at Starbucks? If you have, you know that finding a free plug in a packed coffee house can be hard. These charging stations can be even more valuable at the airport —we’ve all fought for that prime spot in the flight gate waiting area. Now, Monster Media has created a digital experience to accompany the convenience. You’ll see a digital ad while your phone or laptop is being charged. That content is delivered by a 4G LTE connection—the same type of connection that can also deliver information to the display screen on a gas pump.

Wireless charging stations are a huge value-add to customers, and in Starbucks’ case they encourage people to stick around longer—which leads to more coffee sold. For advertisers, this value can be paired with their message—a message that might even be specific to your currently location. Similarly, at the gas pump, customers have the convenience of catching the news or relevant information while pumping gas, and gas stations are able to advertise deals to lure customers into the store to make purchases.

Bottle Recycling Machine

For some of us, returning bottles is a well-known past-time. But for many states, reverse vending machines are becoming common-place. In either case, the system enables consumers to recycle, make money and keep neighborhoods clean. Recycling is so popular today that machines can fill up fast, which causes downtime. How does the vendor know when the machine is full? A cellular connection to HQ. recycling-logo

rePLANET added a cloud connection to their recycling center solution. Without a wireless connection to the machine, a technician would have to drive hours, costing the company hundreds of dollars. Now, with a wireless VPN connection, the machine reports its capacity remotely. The technician’s PC can be remotely controlled with the cellular connection to get updates and new configurations. The new method costs less than 20% of the cost of drive time and shipping and takes about 10% of the total time previously required to correct problems.

So, the next time you pull up to a gas station or visit a store, take a closer look at the digital sign, lottery terminal, air pumps and bottle recycling machines—you won’t be able to see the wireless connection, but you can be sure that it’s working for you and for the stakeholders who put it there. Those wireless connections are making your life easier and more interactive, and driving revenue and extreme savings for organizations all around the world.

Devergy Expands Solar Power Possibilities in Africa

Posted on:

Did you know that roughly 1.7 billion people are not connected to a power grid? In Sub-Sahara Africa, the number is around 500 million. For many, the infrastructure simply doesn’t exist. The modern day conveniences we take for granted such as being able to read at night, cooking on the stove top and refrigeration can be a hassle, or close to impossible, with no access to a reliable source of electricity.

The challenges of installing a power grid in remote and undeveloped areas can be numerous, so how do we reimagine how to deliver reliable electricity and move past the traditional power grid system? Thankfully, Devergy is solving this tricky problem. Using solar power and wireless technology, Devergy has built a sustainable business that’s helping villages in Tanzania and Ghana meet their energy needs.download

Who is Devergy?
Founded in 2010 by Fabio De Pascale, Gianluca Cescon and Daniel Ponz, Devergy is a social enterprise committed to providing an affordable and reliable source of energy to low-income people throughout Tanzania.

Their customers live in rural areas of the country where a power grid is nonexistent and residents do not have the money necessary to purchase a personal solar home system.

Residents in Tanzania typically spend between 6 and 25 USD per month on kerosene, phone charging, and dry-cell batteries for radios. After the installation of Devergy’s solar grids, residents spend as much as 20% less than what they were spending on kerosene for lighting and 50% less for phone charging. Not only does Devergy provide a clean, renewable and reliable source of energy, but it’s also substantially more affordable.

The service is based on village-sized energy micro-grids, which provide solar power to households and small businesses; it allows the users to connect lights and appliances such as radios, TVs and refrigerators. With the smart micro-grids, the usage of installed power is up to 70% more efficient than with equivalent solar home systems.

The key feature of the system is an energy meter that powers the household or business with a pre-paid pay-per-use approach, where customers top up their credit by using a mobile commerce platform, such as Vodacom M-Pesa. This is just like the system you would use to top-up a pre-paid mobile phone.

How it Works
Devergy uses Digi XBee technology for the communication network in its grids. Hundreds of nodes are connected with XBee–making the solar micro-grids smart, cost effective, and manageable. Devergy relies on XBee modules for its smart meters and is using Digi’s ConnectPort X4 for its ZigBee to GPRS gateways. Fabio, co-founder of Devergy says, “The plug and play, flexible nature of the Digi product was fundamental to get our services to the market faster.”

Devergy’s customers receive an unprecedented service thanks to a system that is designed to require no user maintenance and is remotely monitored for faults, so that the reliability and availability of the service is unmatched. Local representation of the company is ensured by the appointment of a village agent, selected based on recommendation by the village committee and trained by Devergy to perform technical support and sales. This ensures the customers always have a well-known and trusted counterpart to deal with.

Devergy has successfully connected more than 800 customers since 2012 to reliable, clean and safe electricity with a service sufficient to satisfy their needs for many years to come.  Currently, they are active in two regions and quickly growing their customer base. In addition to Tanzanaia, the Devergy grids are also licensed to third parties in Ghana, where they power 3 villages.

Today’s Industrial Internet of Things Solutions Are Built, Not Bought

Posted on:

-Every industry and solution requires a
 

The article “Don’t hold your breath for the industrial IoT platform” by Cormac Foster caused quite the buzz when it made its debut on Gigaom last month. With rebuttals from industry players like Mike Dolbec, managing director of Venture Capital GE Software, we took notice.

What stood out the most? Despite the tensions expressed in reader comments, we agree with Foster and thought that some of the best points of the piece were overlooked.

What others overlooked is that Foster isn’t downplaying the role of the Industrial Internet of Things. He’s simply pointing to its enormity.

“The industrial IoT will eventually eclipse consumer markets, in terms of both the number of connected devices and the volume and value of connections. But the market’s potential is so large because it’s not just one market.”

We couldn’t agree more. The Industrial IoT is a mega trend, and its economic value add will show that in time. It is not a single market, but rather a market of markets. For example, our business at Digi International spans over half a dozen different vertical industries and even more underlying applications and use cases.

Different solutions may require different hardware approaches, networking technologies, cloud data storage, reporting and security requirements. We’ve had to learn the different languages of proprietary machines–becoming ‘machine linguists’ in the process.

To approach this vast “megatrend” landscape requires a versatile toolkit of wireless and embedded technologies and software and integration services, because each customer use case and scenario has its own optimized solution.

In the industrial world, you build an IoT solution, you don’t buy one. You might be able to go and buy a wearable at Best Buy or Target, but here in the Industrial IoT there’s no one-size fits all standard today. Furthermore, a lot of new entrants in the supplier space offer one point solution or one point product. They have a single hammer, so everyone’s problem is declared a nail. That’s why their ability to deliver value to customers is limited.

Industrial Internet of Things solutions today are about creating a strategic competitive advantage for your business. If it were easy to do–if you could just buy one off the shelf and implement it–would it be a real advantage? For how long? As early adopters of IoT realize the business benefits of lower costs or the ability to deliver superior customer service, laggards will find themselves at a competitive disadvantage.

As I said before, every industry and solution requires a different combination of technologies and approaches to get the job done. A solution for a city looking to reduce their electricity bill using a smart street lighting system is completely different than a medical device maker who needs to bluetooth-enable products. The same goes for someone deploying precision agriculture equipment, or industrial fuel tanks.

For example, wireless mesh networking technology often powers smart street lighting IoT projects, which can reduce electricity costs that can account for a big chunk of a city’s energy expenses. One of our customers’ systems, which gives city crews a view into every light and its status via a web application, helps cities save up to 85 percent on energy costs. And, with reduced CO2 emissions, it also helps to protect the environment.

The Bottom Line: There’s No Panacea or Single Standard today

Our IoT customer solutions span dozens of industries and hundreds of applications– each with different business goals and technology needs. So, yes, we have to agree with Foster. There’s no one Industrial IoT platform. We wouldn’t hold our breathe either. Internet of Things systems for commercial use are created with industry and application specifications in mind, as they should be. As Foster said, “the market’s potential is so large because it’s not just one market.”
