Last time, in part 1, we explained how the growing M2M market is motivating a move to standards-based solutions, and how the Intel® Intelligent Systems Framework (Intel® ISF) and Digi International M2M Solution Builder Kit meet this need. This time we take a closer look at the elements of Digi’s Kit.


Long History in H/W Gateways

Digi International started over 25 years ago as a commercial networking company focusing mostly on hardware. Their original product was a multiport serial controller for the PC, which evolved by first adding wired Ethernet and LAN connections, then Wi-Fi, RF (such as ZigBee), and finally cellular radios. Today the company emphasizes embedded modules—of their own manufacture and by third parties such as Kontron—integrated with ready-to-go software into wireless M2M gateway products and services.


The company created the scalable iDigi Device Cloud and iDigi Manager Pro software to remotely manage configurations of thousands of connected M2M devices, manage software and firmware updates,  set security policies, and even reboot,  all with centralized access and control of devices or Digi gateways (Figure 2).  Both the iDigi Device Cloud and iDigi Manager Pro software can be used on Digi's or third party products using the iDigi Device Connector (Figure 3).

Under the Hood: Hardware

A residential example of a typical Digi design starts with the M2M Solution Builder kit acting as a home gateway or concentrator, bridged between myriad wireless devices and the home's Ethernet LAN or the on-board 3G cellular radio providing Internet access to the cloud. An 802.15.4-enabled smart meter would report energy usage and time-load statistics, while a Wi-Fi equipped thermostat, washer/dryer and heater blower would accept remote instructions while providing updates on their operational state. The heater blower, for instance, might report increased current draw as a result of a dirty filter. Smart appliances can be scheduled to turn on during off-peak electricity times, or lights can turn on as the homeowner's smartphone broadcasts a text message saying "I'm nearly home" based upon GPS coordinates.


The Digi M2M Solution Builder Kit solves the "connectivity" portion of ISF with many options. Myriad flavors of 2G/3G cellular radios provide high bandwidth data at up to 14.4 Mbits/s (HSUPA at 900 MHz), and Wi-Fi options include 802.11a/b/g/n with WPA2 security.  There's also Gigabit Ethernet plus 802.15.4, although ZigBee remains a future add-on, as is Bluetooth 4.0 and 4G/LTE. Other I/O includes USB 2.0 and audio/video, plus up to four PCI Express mini card connectors for user-added I/O or processing.


But the heart of the hardware remains the Intel Atom E620T 600 MHz CPU and the x86 architecture. Instead of blindly transferring M2M data to the cloud, the Intel Atom Processor allows local processing and computing decision-making. Data can be routed between the gateway I/O (say, from a Wi-Fi connected sensor to USB disk). Image and audio processing can be done on a camera video/sound feed, and only clips or alerts that meet certain criteria need to be broadcast to the cloud. With the power of the E620T, the companion Intel Platform Controller Hub E620T, 1 GB of DDR2 SDRAM, and additional processing that a designer adds to the open PCI Express slots, the Solution Builder is a powerful platform to test-bed an M2M gateway. Future connectivity such as ZigBee or Bluetooth can be plugged in, while the Atom concurrently handles all protocols.


But besides the performance of the CPU itself is the ubiquity of the Intel x86 architecture, instruction set, and huge PC-based ecosystem. Instead of using any old embedded architecture with the challenge of creating device drivers and a custom boot sequence, the x86 architecture and its BIOS-like boot process make development a snap. Linux drivers are available for plenty of components and add-in boards, and existing x86-based applications from other designs can be easily and quickly transported into the Atom/Linux environment. Time-to-market is dramatically reduced from months of embedded development down to weeks or even days.



M2M promises to be the next wave of the Internet, bringing new services, productivity, and connections between previously "dumb" devices that will soon sport intelligence while broadcasting exabytes of data. Digi International's M2M Solution Builder Kit with Intel Atom 620T CPU is a flexible design platform from which to create an M2M gateway design or test platform. Compliant with Intel's Intelligent Systems Framework and connected to the iDigi Device Cloud, the Kit promises interoperability, manageability, and secure data transmission with other M2M nodes.

We're all more connected to the Internet than ever before.  The telecommunications giant Cisco estimated  that in 2012 over 100 million smartphone users will each consume over 1 GB per month and that global data traffic will increase 18 fold between 2011 and 2016. That's a 78 percent CAGR topping out at 10.8 exabytes (10E18) per month by 2016. [February 2012 "Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2011-2016"]

But here's the killer stat: M2M traffic will grow faster (22-fold) than human-initiated data during that timeframe, representing 5 percent of the total. Analyst firm IDC drills down even further: 1.8 billion intelligent systems (not smartphones or tablets) in 2010 doubles to 4 billion by 2015, representing trillions of intelligent connections, many autonomous M2M transactions created without human intervention via the Internet cloud. The point: M2M represents the next wave in embedded systems, with machines talking to machines more often than to humans. [IDC, "Intelligent Systems: The Next Big Opportunity", August 2011.]

Yet despite the tendency to focus on the design task of connecting all those machines and intelligent systems, the real challenge -- and business opportunity -- rests with harnessing the value the M2M data flowing across the Internet. Digi International, a member of the Intel Intelligent Systems Alliance, is a systems integrator focused on providing hardware, software and services designed to connect these systems. Digi recently started shipping  (December 2012) the Digi M2M Solution Builder Kit based upon Intel's Intelligent Systems Framework (ISF) and an Intel Atom processor running Wind River Workbench and Wind River Linux.

The Kit provides a comprehensive out-of-the-box cloud-enabled solution to help M2M developers rapidly get their hardware connected to the cloud by "Making Wireless M2M Easy" (Figure 1). But most importantly, the kit focuses on what developers are going to do with their machine's data before it hits the cloud, how the machine is remotely managed, and what options are available to secure the machine and its data. Not coincidentally, these are all core tenets of Intel's Intelligent Systems Framework.

Figure 1: Digi's M2M Solution Builder Kit makes "Wireless M2M Easy". It includes hardware, software and connectivity to the iDigi Device Cloud. It also supports Intel's Intelligent Systems Framework and is interoperable with other ISF solutions.


Digi International and Intel's ISF

The emphasis on services and systems is what sets Digi apart from most integrators and is why Intel's Intelligent Systems Framework is so appealing. ISF is a "set of recipes" for connected devices, solving the problem of connectivity -- that is, how devices attach to the cloud -- and so much more. The framework brings together hardware, operating systems, tools and more with a focus on: connectivity, security and manageability.

The key ingredients, according to Intel, are:

  • Processor platforms (including Intel® Atom™, Intel® Core™ and Intel® Xeon® ) and related tech like Intel® vPro and Intel® TXT, as well as a range of I/O for flexible communications
  • OSs including Microsoft* Windows*, Wind River* Linux*, and Wind River* VxWorks*
  • Security including McAfee Embedded Control and McAfee Deep Defender
  • Remote manageability capabilities that support third-party management consoles


More importantly, Intel is assuring compatibility between compliant solutions between suppliers. That means Digi's M2M Solution Builder Kit and the iDigi Device Cloud are compatible with ISF compliant products from other Intel Intelligent Systems Alliance partners like Eurotech, McAfee, Wind River and others.  In fact, the Builder Kit itself is composed of Alliance member components: the hardware is Kontron's M2M Smart Services Developer Kit, which when sold by Digi uses a module from Telit Wireless that's based upon an Intel RF component.


Intel's plan with ISF is to take the focus off of the computers that make up M2M and shift it to the task of intelligent computing. For example, previously a DVD rental vending machine designer might've focused exclusively on connecting their machine to the Internet and creating a rudimentary data exchange protocol. The data gathered by the machine is essential for billing and in-machine inventory management.


But there's no reason the video rental machine can't also communicate with other close-by rental machines or even retail stores, advising the customer where to locate an out-of-stock DVD and the best route to get there. Taken further, why not have all similarly branded DVD vending machines share data with close-by soda machines or fast food restaurants to offer customers incentives for food and drinks to go with their movie? Databases of renters' habits could make intelligent suggestions, increasing the revenue per transaction for the cooperative retailers, in this example.


For this to become reality, it's essential that the machines interoperate, for sure. But the future of M2M is monetizing the data flowing into the cloud by parsing it in new ways: aggregating machine- and human-generated data to create new services and increase productivity. Intel's goal with ISF focuses on connectivity, manageability, and security with an emphasis on off-the-shelf hardware, software, and services from ISF-compatible vendors like Digi.


Next time, in part 2, we’ll look under the hood of Digi’s kit to see how they achieve this goal.
