Customer Showcase: Wireless for Today’s Connected City

Posted on:

Every day Digi works with customers around the world to deploy connected solutions that businesses rely on. From the ability to monitor device health to using data to make more informed decisions-connected devices are modernizing business operations. Here are a few of the many companies we are proud to work with.

EMTEST | Public Transitcss-featured-emtest (1)
As city populations continue to grow and public transportation demand rises, public transit agencies are finding innovative ways to handle the influx of passengers. Implementing wireless technology at ticketing kiosks and on-board displays helps streamline operations while also helping to improve the overall rider experience.

EMTest, a technology solution provider for transportation, uses the ConnectCore® 6 as the engine that powers its Emlines system. The ConnectCore 6, based on Freescale’s i.MX 6 applications processor, is a compact module that provides engineers all of the features necessary to build unique wireless applications.

EMTest gives transit operators the ability to facilitate ticket sales more efficiently, optimize vehicle routes—and it provides passenger Wi-Fi. With the fare collection system tied into the rest of the operations team, riders are provided with information such as next stop, travel times, and transfer information. The data collected is also essential for more efficient fleet management.

Owlet Nightshift by Schreder | Connected LightingRoundabout at twilight
As cities deploy LED street lights to cut energy costs, they’re also turning to wireless technology for data collection and remote monitoring for their street lighting.

Utilizing Digi wireless technology, Schréder developed the Owlet lighting solution, which enables cities to retrofit out-of-date lighting infrastructure with long lasting intelligent technology. Within each light is an LED array along with a Digi XBee ZigBee module. The XBee radios create ZigBee mesh network-connecting all of the city’s street lights wirelessly. Data from each light is then sent to a single point, a cellular XBee Gateway, which then  connects to a cellular network.

The XBee Gateway allows the city to monitor and control lighting with Owlet’s web-based management tools. Also, municipalities don’t have to wait for a citizen to report an outage or check lights via scheduled inspections. The lights themselves can tell the city when they need to be serviced or replaced.

AddÉnergie | Electric Vehicle Chargingcss-inline-addenergie
Electric vehicles are a rapidly growing market, and with it, so has the need for charging. AddEnergie specializes in providing charging station networks for electric vehicles. The company provides the charging infrastructure for both the Electric Circuit and the VERnetwork™, the two largest charging networks in Canada.

AddEnergie uses XBee modules to connect stations throughout entire parking lots and a single gateway is used at each lot to enable cloud connectivity. In addition to relying on Digi wireless technology, AddEnergie uses the ConnectCard i.MX 28 as the brains of their system.

The system includes proprietary software, PowerSharing™ and PowerLimiting™, which interface with Digi products and notify the charging stations when energy should be lowered to help reduce costs.

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.


Come see Digi at the spring Entelec Communication Show in Houston April 7th through the 9th at booth #228

These are just some of the ways a preventative maintenance model built on Digi’s award winning wireless devices and cloud solutions can benefit the Oil & Gas industry. If you would like to learn more about how connected assets are driving business transformation in the Oil & Gas industry, join us at the Entelec Trade Show at booth #228 Tuesday, April 7 through Thursday, April 11 at the George R. Brown Convention center in Houston, TX.

Australian Researchers Improve IEQ with ZigBee Based Sensor System

Posted on:

As the cost of energy rises and environmental concerns move us toward new sources of energy, how do we ensure we make the most out of every watt? There are a number of companies and organizations emerging to address this truly global issue.

University of Sydney Indoor Environmental Quality (IEQ) researchers Tom and Alex Parkinson, built SAMBA to help solve the balancing act between comfort and reducing energy consumption. SAMBA is a platform comprised of remote sensors deployed throughout commercial office environments and a web interface for data visualization. The system collects data points — enabling building managers to improve IEQ and save costs.

The platform is made possible by wireless technologies like ZigBee mesh networking and cellular data communications. Additionally, recent advancements in sensor technology have made it possible to create sensor nodes capable of measuring a variety of parameters, while maintaining a small form factor and remaining affordable.


How SAMBA Works
Within each node you’ll find sensors to monitor thermal comfort, acoustics, lighting, and indoor air quality. Processing at each node is handled by an ATmega328 chip running an Arduino sketch. A cool feature of the node is a flash memory chip. This helps prevent any data loss in case there’s a network failure by allowing data to be stored locally. Once the data is collected it hops from XBee to XBee until it reaches the central hub. Data is sent from each node at an interval of once every 5 minutes.

The central hub/cellular gateway is currently a Raspberry Pi with a cellular module. The gateway does some minor processing before sending data over the cellular network to SAMBA’s server. Due to the mesh networking capabilities of the sensor nodes, it is possible to just have one central hub per building. This makes the solution extremely cost efficient. As the team works to take this to production and scale their operation, they’re evaluating replacing the Raspberry Pi with the XBee Gateway.

Why ZigBee
The development team chose to use ZigBee for a multiple reasons. For one, the mesh networking capability makes the deployment of nodes more flexible and, in many cases, only one central hub is needed per building. Another factor was the development tools at their disposal like the open source Arduino library for the XBee ZigBee Radios. You can access that library here. This library helped them to cut down development time significantly.

The SAMBA crew is already getting some nice recognition throughout Australia. Just last week, Green Cities included them on their list of Weapons of Mass Creation! To learn more about the University of Sydney’s Indoor Air Quality Lab, click here visit their site.

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.
