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.

The Evolution of LTE for IoT and M2M Devices

Posted on:

When you hear LTE you probably start thinking of fast speed, high bandwidth, HD video, your favorite apps…lots of data. But, LTE can also be dialed back to create power-efficient cellular connected devices. This is a useful solution for connecting IoT devices like sensors and actuators to the Internet since they don’t transmit lots of data and operate under strict energy budgets.

Did you know there’s more than one type of LTE?

Within LTE there are multiple categories as defined by the global cellular standards body, 3GPP. Some of the categories are still in the process of being developed but one thing is clear, there will be split in the evolution of LTE. In one direction, LTE will continue to increase speed and bandwidth for smartphones and other data-hungry applications.  In the other direction, we’ll see cellular providers accommodating machine-to-machine communication with LTE designed for low power, low data, and low cost.

In the video below, Digi CTO, Joel Young, provides an in-depth look into how LTE technologies are evolving to accommodate the various needs of cellular connected devices.

We’re still in the early days of LTE for machines, but more advancements in LTE for M2M/IoT are on the horizon. Check out our technical brief “M2M in an LTE World,”  for more details on how these LTE categories differ and what it means for M2M/IoT product designs.

Enlight Teams with Digi to Create Smarter, Safer, and More Cost-Efficient Lighting Environments

Posted on:

For ten years, Portugal-based Enlight has been working to meet ever-increasing municipal demands for higher levels of control, monitoring, and energy-efficiency. Enlight designs and deploys sophisticated urban lighting systems around the world.

EnlightAmong the highest areas of demand for cities are their networks of thousands of street lights deployed throughout the urban landscape. For cities, street lighting can cause maintenance headaches, safety concerns, and become surprisingly expensive. Increasingly, cities are turning to external partners to handle city lighting. Enlight saw the opportunity to provide smart solutions for monitoring, energy control, and maintenance.

Today, Enlight devices meter all electrical parameters of a light and they can send notifications about burned-out bulbs and other maintenance issues. To enable monitoring and control they built their own network and created a smartphone app. The Enlight engineering team worked with Digi’s API framework. It was a fast and easy solution which enabled communication for all their smart lighting devices.

Enlight’s street lights contain a smart device that controls light. It communicates through a mesh network to a local control box on that street. At the control box, Digi’s cellular gateway manages all the street lighting groups assigned to it using programmed instructions from a centralized operations center. This enables remote control, monitoring, and large-scale data collection for lighting systems in municipalities around the globe.

How to Meet Critical Infrastructure Requirements with Cellular Devices

Posted on: 1 Comment

Critical infrastructure operations—whether it be an electrical substation, wastewater treatment plant, or traffic control center–are relying more and more on networked assets like sensors and control switches. But, the introduction of connected devices also raises security risks. Since these systems control services both businesses and consumers heavily depend upon, regulations are in place to ensure our infrastructure remains in working order and secure from threats.

Much like the laws you abide by while driving such as wearing your seatbelt, staying within the speed limit, etc., utility providers connecting assets with cellular LTE must follow certain standards and protocols to ensure security and reliability. In North America, these rules and standards are referred to as North American Electric Reliability Corporation Critical Infrastructure Protection or more conveniently as NERC-CIP. For our friends in Europe, the standard is called “European Programme for Critical Infrastructure Protection” or EPCIP for short.

What makes a network solution NERC-CIP compliant? In this video, Brad Cole, Device Cloud Product Manager, walks through the steps many of our utility customers take in order to deploy secure and connected critical infrastructure.

In short, critical infrastructure operators must comply with these reliability standards—or face large penalties. The mandatory Reliability Standards include CIP standards 001 through 009 (see below), which address the security of cyber assets essential to the reliable operation of the electric grid.

  • CIP-001: Covers sabotage reporting;
  • CIP-002: Requires the identification and documentation of the Critical Cyber Assets associated with the Critical Assets that support the reliable operation of the Bulk Electric System;
  • CIP-003: Requires that responsible entities have minimum security management controls in place to protect Critical Cyber Assets;
  • CIP-004: Requires that personnel with authorized cyber or unescorted physical access to Critical Cyber Assets, including contractors and service vendors, have an appropriate level of personnel risk assessment, training, and security awareness;
  • CIP-005: Requires the identification and protection of the Electronic Security Perimeters inside which all Critical Cyber Assets reside, as well as all access points on the perimeter;
  • CIP-006: Addresses implementation of a physical security program for the protection of Critical Cyber Assets;
  • CIP-007: Requires responsible entities to define methods, processes, and procedures for securing those systems determined to be Critical Cyber Assets, as well as the other (non-critical) Cyber Assets within the Electronic Security Perimeters;
  • CIP-008: Ensures the identification, classification, response, and reporting of cybersecurity incidents related to Critical Cyber Assets; and
  • CIP-009: Ensures that recovery plans are put in place for Critical Cyber Assets and that these plans follow established business continuity and disaster recovery techniques and practices.

The Digi TransPort WR31 comes with features and configuration options to simplify securing critical infrastructure assets like electric and gas meters or traffic control cameras. The Digital I/O can address physical security concerns and Remote Manager will log user information and even device changes.
