Smart City Series: 4G LTE & Smart Infrastructure – Q&A Follow-Up

If your inbox is anything like ours, it’s full of emails touting “Smart Cities” as the next big thing, but how are cities actually using cellular technology to run smarter?

In a recent webinar, Digi’s Cellular Product Manager, Andrew Lund, shared real-world examples of 3G/4G LTE in infrastructure applications, along with the challenges and questions that need to be answered to get there.

Below, Andrew covers questions from the Q&A that we didn’t have time to answer live. If you’d like to watch the webinar recording and learn more about how Digi enables Smart Cities.

What accelerated lifecycle testing have you performed on the WR31 and are you able to share your results?
Specific test results are shared on a business case basis and only under NDA, but we can share that the WR31 was subjected to a Highly Accelerated Life Test (HALT) in line with our standard testing.  This testing is divided into three sections: temperature, vibration and a combination of vibration and temperature.

In each section, the Unit Under Test (UUT) is tested at the operational limit, the functional limit, and the destructive limit (if applicable). For the WR31, the functional limit was above the operating limit, meaning it functioned above and beyond the threshold we expected it to.

Who does the integration with energy meters / HVAC controllers ? Does Digi do that type of integration or is it some system integrators who are Digi partners who are responsible for integration?
Both options are available, depending on the customer and the goals. In cases where, for example, an OEM wants to add cellular connectivity to their offer, Digi and its partner would work directly with the OEM. In cases where the customer is an end user, for example an city or state department, Digi would work with a system integrator or value added reseller to deliver the final solution.

Can you please share how the Garbage Collection and Emailing System was implemented?
This was done by Digi’s Wireless Design Services group. More details and a video can be found here.

Does the WR31 product have the relevant Australian compliance e.g. C-Tick, A-Tick?
Yes.

Are there plans to support LTE 700 Mhz Band 28 in future?
Yes—stay tuned for details.

Rather than offer a device management application for us to use, does Digi offer a managed service for its product set?
Digi has implemented bespoke managed services programs for customers, but it is more common for us to partner with 3rd party managed services companies.

Does the WR31 support DNP3/IP?
Yes, the TransPort WR line supports DNP3.

Does the WR31 has an LTE to NextG fallback?
Yes, the WR31 offers LTE with fallback to Telstra’s NextG (i.e. 850MHz) network.

Do you have an example of an application in France?
We have many, many customer and applications in France—please contact your Digi rep or Digi partner for details.

WR31 is a nice product, but how to beat the competition having this form factor in the market for many years. E.g. Welotec, Moxa, etc.
“How to beat…” questions are a bit tough to answer in the abstract, but you can discuss specifics with your Digi rep or partner. Nor now, let’s focus on positioning the WR31 where it will have clear advantages. The WR31 is the best fit in applications that DO NEED: LTE, strong price/performance (i.e. affordable), Modbus/DNP3 bridging, and advanced security and routing (VPN, authentication, encryption, etc, and DON’T NEED vendor-specific object libraries or Modbus/DNP3 translation.

Is there a version that supports XBee 868 LP?
No, currently there are no versions of the WR31 with an XBee radio, although that is an interesting concept, and worth discussing further with your Digi rep or partner.

Is it possible for the hardware to move from Cellular communications to a WiFi network and use this to communicate, WiFi becomes available – and if so – what product fits best?
The TransPort WR44 supports Wi-Fi and 4G/4G LTE comms and is used in this kind of least cost routing scenario.

What is different in terms of speed in WR21 and WR31?
The WR21 and WR31 share the same WWAN radio and processor architecture—there is no material performance difference between the two.

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

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.”
