SOLUTION BRIEFIntel® M2M Reference Design based on the Intel® Atom™ processorMachine-to-Machine (M2M) ApplicationsIntel® M2M Reference Design for Smart ServicesDevelopment based on the Intel® Atom™ ProcessorWith a footprint the size of a credit card† the design supports a variety of wireless connectivity and delivers thecomputing performance required for M2M (machine-to-machine) applications. The Connected World Intel and Ericsson* both forecast that tens The need for M2M connectivity and compute of billions of devices will communicate is accepted worldwide by technology over the Internet this decade.1,2 Cellular leaders who share the vision that most, if carriers worldwide believe their networks not all, electronic devices will be connected will serve more machines than people.3 to the Internet in the not too distant future. This will create a pervasive Internet that When those devices become connected, enables more intelligent devices, and Intel new opportunities for services, delivery of is ready to meet the needs of a connected content, system optimization and a limitless world. number of other possibilities will emerge. Small Connected Compute Platform Sparing system designers from mastering the complexities of wireless connected computer technology, the Intel® M2M Reference Design, based on the Intel® Atom™ processor, provides a manufacturing- ready platform supporting a variety of wireless connectivity, including 3G/4G wireless broadband, WiFi* and solutions using the IEEE 802.15.4 WPAN technology such as ZigBee*. Now, manufacturers of connected devices can dramatically lower development and product cost with this Intel Atom processor-based platform based on COM Express* form factor architecture. Measuring a mere 84 mm x 55 mm, this “nano” form factor (Figure 1) is ideal for space-constrained, fanless environments. The compute module sits on a carrier board in a case measuring 100 mm x 67 mm, not including antennas or connectors.

Connectivity Example for Gateways and Direct/Indirect Nodes M2M Direct node: “Direct” interface to the cloud. Attaches directly to a wireless broadband network using 2.5G, 3G or 4G radios. M2M Gateway: “Direct” interface to the cloud and indirect nodes. Has a wired or wireless broadband network interface and one or more short haul or WLAN interfaces for connecting to indirect nodes.
