Why connect to the cloud with the Atmel | SMART SAM W25?

The “thing” of IoT does not have to necessarily be tiny.

The Atmel | SMART SAM W25 is, in fact, a module — a “SmartConnect Module.” As far as I am concerned, I like SmartConnect designation and I think it could be used to describe any IoT edge device. The device is “smart” as it includes a processing unit, which in this case is an ARM Cortex-M0-based SAMD21G, and “connect” reminds the Internet part of the IoT definition. Meanwhile, the ATWINC1500 SoC supports Wi-Fi 802.11 b/g/n allowing seamless connection to the cloud.

What should we expect from an IoT edge device? It should be characterized by both low cost and power! This IoT system is probably implemented multiple times, either in a factory (industrial) or in a house (home automation), and the cost should be as low as possible to enable large dissemination. I don’t know the SAMD21G ASP, but I notice that it’s based on the smallest MCU core of the ARM Cortex-M family, so the cost should be minimal (my guess). Atmel claims the W25 module to be “fully-integrated single-source MCU + IEEE 802.11 b/g/n Wi-Fi solution providing battery powered endpoints lasting years”… sounds like ultra low-power, doesn’t it?

The “thing” of IoT does not necessarily have to be tiny. We can see in the above example that interconnected things within the industrial world can be as large as these wind turbines (courtesy of GE). To maximize efficiency in power generation and distribution, the company has connected these edge devices to the cloud where the software analytics allow wind farm operators to optimize the performance of the turbines, based on environmental conditions. According with GE, “Raising the turbines’ efficiency can increase the wind farm’s annual energy output by up to 5%, which translates in a 20% increase in profitability.” Wind turbines are good for the planet as they allow avoiding burning fossil energy. IoT devices implementation allows wind farm operators to increase their profitability and to build sustainable business. In the end, thanks to Industrial Internet of Thing (IIoT), we all benefit from less air pollution and more affordable power!

The ATWINC1500 is a low-power Systems-on-Chip (SoC) that brings Wi-Fi connectivity to any embedded design. In the example above, this SoC is part of a certified module, the ATSAMW25, for embedded designers seeking to integrate Wi-Fi into their system. If we look at the key features list:

• IEEE 802.11 b/g/n (1×1) for up to 72 Mbps
• Integrated PA and T/R switch
• Superior sensitivity and range via advanced PHY signal processing
• Wi-Fi Direct, station mode and Soft-AP support
• Supports IEEE 802.11 WEP, WPA
• On-chip memory management engine to reduce host load
• 4MB internal Flash memory with OTA firmware upgrade
• SPI, UART and I2C as host interfaces
• TCP/IP protocol stack (client/server) sockets applications
• Network protocols (DHCP/DNS), including secure TLS stack
• WSC (wireless simple configuration WPS)
• Can operate completely host-less in most applications

We can notice that host interfaces allow direct connection to device I/Os and sensors through SPI, UART, I2C and ADC interfaces and can also operate completely host-less. A costly device is then removed from the BOM which can enable economic feasibility for an IoT, or IIoT edge device.

The low-power Wi-Fi certified module is currently employed in industrial systems supporting applications, such as transportation, aviation, healthcare, energy or lighting, as well as in IoT areas like home appliances and consumer electronics. For all these use cases, certification is a must-have feature, but low-cost and ultra-low power are the economic and technical enablers.

Kaivan Karimi talks IoT and wearables at Designers of Things

Designers of Things — a two-day conference dedicated to the explosive and exciting potential of wearable tech, 3D printing and the Internet of Things — kicked off this morning with a session from Kaivan Karimi. During his presentation, the Atmel VP and GM of Wireless Solutions broke down the evolution of technologies necessary for wearable devices to succeed.

Undoubtedly, wearables have emerged as an extremely hot topic within the technology industry with big name enterprises and small startups alike working endlessly to develop the next high-profile device. Wearables, which are not only being integrated into smart fashion and allowing users to access technology hands-free, are now accelerating the self-quantification movement and paving the way for the upcoming always-on healthcare revolution. Using specific examples from the smartwatch and smart fashion realms, Karimi educated event attendees on the underlying hardware, software, sensing, connectivity, and security technologies needed to make wearables happen, and get them integrated into already existing broader networks.

Karimi began the session by making it clear that wearables are a subset of the IoT, which is the wider umbrella of connected things. When explaining the size of this umbrella, Karimi stated, “The Internet of Things is like sunlight, it covers everything.” He emphasized to attendees that the IoT will go on to impact all aspects of industry and commerce, therefore migrating to devices that collect data: “If you can’t track it, you can’t improve it”.

Despite the fact that it is a mere subset in today’s ever-evolving, constantly-connected world, Karimi stressed that the wearable tech space is not a single entity. “Wearables are not a single segment. There are different categories with different requirements,” he urged. High-end or local processing wearables include smartwatches that run standalone systems such as Android Wear, Tizen for the Gear line of devices and the upcoming Apple Watch. Mid-range wearables are more along the lines of smartphone accessories, which use thin client models and rely on applications on the smartphone. The third category, low-end or limited devices, usually boast no display or feature a limited user interface and act more as a sensor aggregator. This category includes devices such as Fitbit, Polar Loop and other fitness trackers.

“Wearables is one of the edge nodes of the IoT infrastructure,” Karimi continued as he put wearables in perspective of the IoT. Karimi then went on to share several reasons as to why wearables have experienced immediate adoption so far — seamless and ability to integrate into our lives; ease-of-use; inexpensiveness; health and fashion-focused; the potential to save lives; and, the quantified self movement. “The value created by IoT is not just dollars and cents but how we live our lives,” he added.

However, as more devices become connected particularly those adorned to bodies, security and privacy concerns will arise. According to Karimi, this can and will inhibit the growth of wearable tech and IoT as a whole; therefore, how we secure the devices will play an integral role in the development of IoT. “Security and privacy are major growth inhibitors of wearables,” explained Karimi.

Karimi then depicted a time in the relatively near future where hackers could open your doors, access your neighborhood’s streetlights, as well as take control of your toaster oven. Creating the necessary hierarchal gateways to protect access to connected devices and its data will be key in a connected tomorrow. “When it comes to security for the Internet of Things, stakes are much more severe,” he told the Designers of Things audience.

Major advancemetns in technologies like semiconductors are attributed to growth of wearable tech, Karimi revealed. Semiconductors are getting faster, cheaper, smaller and more powerful yet less power consuming, which make them well-suited for smaller devices that need to be on all-day. But one of wearables biggest allies will be contextual computing, which Karimi revealed “will be the driving force behind the next wave of technology.”

The use of big data, sensor fusion, personal history, GPS and social media will also enable computers to know who we are which in turn will let them better serve us. “The future of data analytics will see a shift from reporting to prediction,” Karimi said. “In the future, your devices will know you better than your spouse knows you or you even know yourself.”

Wearables aren’t limited to smartwatches and fitness trackers; in fact, Karimi teased the audience with new form factors coming down the chain. “New form factors are on the way. It’s like pills you take to authenticate yourself,” he noted.

Karimi went on to conclude with a discussion around wearables and IoT in the healthcare setting. “The future of healthcare with wearables is the always-on revolution,” he told attendees. “In order for IoT and wearables to work in healthcare, you have to link the databases.”

So what does the future have in store for wearables? According to Karimi, over the next four to five years, we can expect that wearables will:

• Be here for the long-haul
• Enable a variety of new services
• Allow medicine to become more personalized
• Revolutionize healthcare
• Focus on prevention vs. disease management

According to analysts at ABI Research, over the next five years businesses will integrate into their wellness plans more than 13 million wearable devices with embedded wireless connectivity. Wearable tech also ties into the rapidly evolving Internet of Things, which refers to a future world where all types of electronic devices link to each other via the Internet. Today, it’s estimated there are nearly 10 billion devices in the world connected to the Internet, a figure expected to triple to nearly 30 billion devices by 2020. The inherent versatility of Atmel’s microcontrollers and radio chips have made our silicon a favorite of Makers and engineers. As allude to in Kaivan Karimi’s presentation, Atmel is smack dab in the middle of the wearable revolution, with a comprehensive portfolio of versatile microcontrollers (MCUs) that power a wide range of platforms and devices.

$25 device lets doctors diagnose from anywhere

Remote diagnostics is an emerging field that allows healthcare workers to perform tests on patient samples in the field and to get results interpreted by medical experts remotely. However, providing care in this manner is often associated with expensive equipment, extensive training and access to relatively developed telecommunication infrastructure. In an attempt to overcome these obstacles, a group of scientists have published a new paper describing a device dubbed the universal Mobile Electrochemical Detector (uMED). The machine itself can currently test for Malaria — with hopes to one day diagnose diseases such as Ebola, HIV, E. Coli, hepatitis, influenza, West Nile virus and Dengue fever — by analyzing drops blood and water for chemicals or disease. Once the uMED is linked up to a cell phone, it can then upload the information to the cloud for instant analysis – all for just $25 a unit.

The inexpensive design could make the rising trend of remote diagnostics an everyday reality across the globe. The team developed a custom electrochemical sensor compatible with an Atmel-based Arduino in order to power the inner workings, while a simple audio cable connects the medical gadget to a cell phone for uploading. Subsequently, uMED can easily adapt to geographic needs and updated with minimal training. Many of the medical tests are conducted with an electrode, testing and receiving various data from drops of liquid on test strips. The devices also features a vibration motor to mix samples, whenever the need arises.

“Integration with the cloud is important especially if the required expertise is not present on site to interpret the tests,” Head study scientist Alex Nemiroski tells Popular Mechanics. Once the information is collected by the uMED, it is uploaded to a cloud database just by making a phone call. This device does not require a strong data connection or a smartphone, making it viable almost anywhere on the globe.

Nemiroski breaks down this choice to not create a smartphone app to Popular Mechanics, “We decided instead to focus on a universal solution that is compatible with all generation of cellular technology.”

Although the use of mobile devices continues to rise throughout most of the world, there are still billions of people still required to use older, often times obsolete, technologies for means of communication. “People in many of these regions routinely use their low-end mobile phones for banking, news, education, and healthcare,” he concluded. “Even in many of the poorest rural areas in the world that lack resources to pave roads, run power lines, or install pipes, people still have access to mobile phones.” Therefore incorporating medical testing into this handheld technology could only help improve the general well-being of the world population.

China is leading the IoT pack

Analysts at GSMA confirm that China is the global leader in the adoption of M2M technology – with over 50 million connections or more than one quarter of the total M2M market in 2013.

 Indeed, close collaboration between the country’s leading mobile operators China Mobile, China Unicom and China Telecom, state-owned enterprises and the government has enabled the market to grow dramatically in a relatively short period of time, laying the foundations for further expansion and the development of the Internet of Things (IoT).

“China is a rapidly developing country that is investing in communications technologies that will make its cities smarter and provide a better quality of life for its citizens,” explained GSMA CTO Alex Sinclair.

“Proactive government support has benefited China and its mobile operators, whereas in many global markets, regulatory uncertainty has held back the deployment of M2M solutions. The addressable market and the opportunity for further growth is immense, especially when one considers the sheer number of ‘things’ such as cars or domestic appliances that could potentially be connected by mobile.”

According to Sinclair, Asia is currently the largest regional M2M market, accounting for 40 per cent of the world’s 189 million M2M connections at the end of 2013. To be sure, Asia added 55 million M2M net connections between 2010 and 2013 and China was the primary driver of growth in the region, adding nearly 39 million M2M connections during the period.

Demand from the energy and transportation industries has driven much of this early growth, while M2M solutions are also gaining traction in the automotive, smart city, healthcare, education and retail sectors.

It should also be noted that China’s leading mobile operators have developed sophisticated 
M2M service propositions that go beyond the provision of basic connectivity. These typically combine a generic horizontal platform, designed to work across all industry sectors with dedicated vertical platforms for specific application areas, such as automotive or healthcare.

An $18 billion wearables enterprise market

Analysts at ABI Research confirm that wearable device technologies will become an integral part of enterprise mobile enablement strategies – increasing at an impressive CAGR value of 56.1% over the next five years.

As expected, the North American region will be the largest, growing at a CAGR value of 39% over the next five years. Meanwhile, the Asia-Pacific region is slated to become the second largest market, outpacing Europe by 2019 with a CAGR of 90%.

“There are cases being made for wearables in the enterprise despite the relative newness of the technology. However, which wearables are primed for enterprise usage and adoption is a more important question,” senior ABI Research enterprise analyst Jason McNicol explains.

“Wearable technology such as smart glasses and those used for healthcare are better suited for the enterprise as corporate-liable devices. Smartwatches, on the other hand, will most likely follow the trend of BYOD into the enterprise.”

More specifically, ABI Research has identified six types of wearable devices: smart glasses, cameras, smart watches, healthcare, sports and activity trackers and 3D motion trackers. Healthcare wearables, smart glasses and smart watches will be the dominant form-factors purchased by the enterprise and used by employees.

“Like any digital device supporting the enterprise, wearables will need to be secured and managed,” ABI practice director Dan Shey adds.

“Wearable use cases in field services, maintenance, training, etc., highlight the need for enterprise mobility management providers, mobile operators, enterprise application and platform vendors, system integrators, device OEMs and other enterprise mobile suppliers to add services to support wearables. Enterprise connectivity continues at a rapid pace and its benefits are only achieved when end-to-end solutions – including security and management services – support the devices and connections.”

It should be noted that ABI Research expects a total of 90 million wearable devices to ship in 2014 across multiple markets. As senior analyst Joshua Flood notes, wearable tech will be characterized by a diversity of products, although only those with clear use-cases and target audiences are likely to succeed.

“[2014] will be a critical period for the acceptance and adoption of wearable devices. Healthcare and sports and activity trackers are rapidly becoming mass-market products,” the analyst says.

“On the flipside, wearable devices like smart watches need to overcome some critical obstacles. Aesthetic design, more compelling use cases, battery life and lower price points are the main inhibitors. How vendors approach these challenges and their respective solutions will affect the wearable market far in the future.”

According to Flood, chipset vendors are beginning to pave the way with interesting wearable reference designs that will allow non-technology OEMs and brands to quickly jump upon the wearable device bandwagon and offer diverse, innovative, unique and stylish solutions.

“While smart glasses could be the starting point moving away from today’s touchscreen smartphones to eyewear devices using a voice interface, pricing, battery life and style will all play crucial roles for market traction,” he continues.

“Due to these limitations, the enterprise sector will be the early target for smart glasses before they are ready for mass-market adoption. [We] expect more than two million smart glasses [to] ship in 2014, [with] the category forecast to grow rapidly from 2015 onwards. Mobile enabling technologies like augmented reality will play a vital part in enhancing smart glass capabilities.”

Indeed, smart glasses and smart watches will account for a relatively small segment of the wearable device market in 2014, with medical, wellness and sports and activity wearable devices expected to provide the bulk of wearable device shipments this year.

“Activity trackers will continue to be the most popular wearable device as people carefully monitor their activity levels and energy output,” Flood concludes. “Concerns around weight management and even obesity are the prime drivers behind this wearable device type. The collection and analysis of the captured personal performance data through associated websites and their communities is also a crucial element in building out the use-case.”
