Iridium teams with Amazon Web Services for satellite IoT

By Nick Flaherty

Iridium Communications is working with Amazon Web Services (AWS) to tackle the challenges of using satellite links for the Internet of Things.

Low data rate sensors are a suitable candidate for satellite links, especially in rural areas and the 80% of the Earth's surface that doesn't have cellular coverage, but the latency and timing is a major issue.

Iridium CloudConnect should be the first satellite cloud-based solution that offers global coverage for Internet of Things (IoT) applications when it launches 2019.

Iridium has a constellation of 66 crosslinked satellites and is completing a $3 billion project to replace its entire original satellite constellation with new satellites, known as Iridium NEXT. Seven launches have taken place with launch provider SpaceX, delivering 65 new satellites to Low Earth Orbit (LEO), with the final launch of 10 satellites planned for later in 2018. Upon completion, a total of 75 Iridium NEXT satellites will have been delivered to space, with 66 in the active constellation and nine serving as on-orbit spares. The LEO architecture has much shorter signal transit times than geostationary satellite systems, giving lower latencies.

Through CloudConnect, Iridium customers will be able to take advantage of AWS IoT, while existing AWS customers will have a cost-effective way to expand their geographic IoT footprint to anywhere on the globe.

According to IHSMarkit the global IoT is expected to continue rapid growth to approximately 75 billion devices by 2025. 

 AWS IoT will create a simplified process for companies to integrate Iridium's satellite reach with AWS, increasing speed to market. Through this arrangement, customers will be able to reduce engineering efforts, lower fixed operating costs, and reduce time to develop new products and services, through the power and capabilities of AWS IoT.

The Iridium IoT service has approximately 630,000 active devices as of June 30, 2018, growing at 19 percent a year over the last three years. Each existing Iridium partner will be able to rapidly adopt AWS services though the automated translation of the Iridium network's proprietary protocols and industry standard IoT protocols supported by AWS IoT, to and from the appropriate devices and databases.

"Iridium CloudConnect will completely change the speed at which a satellite IoT solution can be deployed and will allow existing AWS customers to keep everything the same on the back end, while opening up the opportunity to quickly expand their coverage," said Matt Desch, CEo of Inridium. "This is a major disruption for satellite IoT. Costs will drop, time to market will speed up, risk will be reduced, and AWS IoT customers that choose Iridium CloudConnect can now enjoy true global connectivity for their solutions."

Full open source mbed stack for Bluetooth Low Energy links to Pelion IoT platform

By Nick Flaherty

Arm is launching the industry's first open-source, fully qualified and product-ready Bluetooth 5 Low Energy (BLE) software stack, giving developers more flexibility in developing new designs for the Internet of Things (IoT) with BLE wireless connectivity.

The Mbed Cordio Stack sits alongside a set of Mbed OS connectivity for Thread, Wi-Fi, 6LoWPAN, LoRa and cellular to provide the different options for flexible, secure and connected IoT designs.

According to the 2018 Bluetooth Market Update, there will be more than 5 billion Bluetooth device shipments by 2022, with 97% of them containing BLE. Bluetooth Mesh will also drive new market opportunities across building automation, sensor networks, and other IoT solutions.

Bluetooth 5 supports 2x the data rate, 4x the range and 8x the broadcast capability compared to the previous version, Bluetooth 4.2. The Cordio BLE stack is integrated with the free, open-source embedded operating system, Mbed OS so that 350,000 Mbed developers can access it and get forthcoming access to Bluetooth Mesh.

This also allows devices to be securely connected and managed through the Pelion IoT Platform,

For silicon partners, the solution gives them access to a full-featured, production-ready Bluetooth 5 stack as part of their Mbed OS offering and the ability to port to additional platforms. Having complete open source access to the stack removes the risk of relying on a stack vendor says Arm, and allows them to meet changing requirements where full source code availability is critical.

Embedded drives microcontroller growth

By Nick Flaherty

Sales of microcontrollers will be driven to a record high by the spread of embedded control in systems, more sensors, and the rush to connect end-use applications to the Internet of Things (IoT), according to a new report by IC Insights.

The market for microcontrollers is expected to continue hitting record-high annual revenues through 2022 after worldwide sales dropped 6% in 2016. After reducing inventories in 2016, systems manufacturers stepped up purchases of microcontrollers in 2017 with unit shipments surging 22% and strong growth continuing in 2018. IC insights has raised its projection for MCU shipments to 18% in 2018 with the unit volume reaching nearly 30.6 billion and revenues are forecast to rise 11% in 2018 to an all-time high of $18.6 billion, followed by 9% growth in 2019 to about $20.4 billion (Figure 1).

Figure 1

The Mid-Year Update also raised the five-year growth projection of MCU sales to a CAGR of 7.2%, reaching nearly $23.9 billion in 2022, with unit shipments increasing by a compound annual growth rate of 11.1% to about 43.8 billion in the final forecast year.

Prices dropping 
The average selling price (ASP) for microcontrollers fell to the lowest point ever in 2017 and prices are continuing to drop at about the same rate in 2018. However, the annual rate of decline has eased in the last five years compared to earlier this decade. The new forecast for MCU ASP shows the average selling price falling by a CAGR of -3.5% in the 2017-2022 period, much slower than the -5.8% decline seen during the 2012-2017 period and the 20-year CAGR of -6.3% between 1997 and 2017.

A key factor in the 2017 recovery of MCU sales from the decline in 2016 was a turnaround in the smartcard microcontroller segment. About 40% of total MCU shipments are currently for smartcard applications, but that is down from about half early in this decade. 

Excluding smartcard MCUs, sales of “general” microcontrollers for embedded systems, automated control, sensing applications, and IoT-connected things are forecast to grow 11% in 2018 to $16.4 billion after rising 14% in 2017. Shipments of general MCUs are projected to climb 25% in 2018 to 18.9 billion units after rising 21% in 2017. General microcontrollers now represent a little over 60% of MCU unit shipments and are forecast to reach 68% of the total in 2022. Currently, general MCUs generate about 88% of total microcontroller revenues, and they are expected to reach 90% of the entire market value in 2022.

Across nearly all MCU applications, strong growth in 32-bit microcontrollers has reshaped the market as suppliers aggressively promote more powerful designs that are cost competitive with 8-bit and 16-bit devices, which have typically been used in consumer products and other high-volume systems. In some cases new 32-bit MCUs are being priced below the cost of 8-bit microcontrollers. On average, 32-bit MCUs were selling for about twice the amount of the ASP for all microcontrollers in 2012 ($1.76 for 32-bit versus $0.88 for total MCUs). In 2018, the ASP for 32-bit MCUs is expected to be just $0.09 higher than the ASP for all MCUs, and by 2022, the difference is forecast to shrink to $0.05 ($0.60 for 32-bit versus an average of $0.55 for total MCUs).

Wireless LED kills cancer cells

By Nick Flaherty

Researchers from Waseda University in Japan and the Japan Science and Technology Agency developed a new bioadhesive, wirelessly-powered light-emitting device which could better treat cancers in delicate organs.

Conventional photodynamic therapy induces cancer cell death by using photosensitizing agents, which localize in tumors and activate with exposure to a specific wavelength of light. In recent years, low-dose and long-term photodynamic therapy (metronomic photodynamic therapy, mPDT) has shown promise in treating cancers in internal organs. The problem with mPDT is, however, is that because the light intensity is extremely low (1/1000 of the conventional method), the antitumor effect cannot be obtained if the light source shifts even slightly away from the tumor, making the illumination insufficient.

"To address this issue, we have developed a wirelessly-powered optoelectronic device that stably fixes itself onto the inner surface of an animal tissue like a sticker with bioadhesive and elastic nanosheets, enabling a continuous, local light delivery to the tumor," says Toshinori Fujie, associate professor of biomedical engineering at Waseda University. The nanosheets are modified with a protein-inspired adhesive polymer called polydopamine, which can stabilise the device for more than 2 weeks without surgical suturing or medical glue. The light-emitting diode chips in the device are wirelessly powered by near-field-communication technology.

To test its effectiveness, tumor-bearing mice implanted with the device were injected with a photosensitizing agent (photofrin) and exposed to red and green light, approximately 1,000-fold intensity lower than the conventional PDT approaches, for 10 consecutive days. The experiment showed that the tumor growth was significantly reduced overall. Especially under green light, the tumor in some mice was completely eradicated.

Associate Professor Fujie points out, "This device may facilitate treatment for hard-to-detect microtumors and deeply located lesions that are hard to reach with standard phototherapy, without having to worry about the risk of damaging healthy tissues by overheating. Furthermore, because the device does not require surgical suturing, it is suitable for treating cancer near major nerves and blood vessels, as well as for organs that are fragile, that change their shape, or that actively move, such as the brain, liver, and pancreas."

Flexible circuit can be produced on a home printer

By Nick Flaherty
Students from Canada has developed a technique to produce flexible electronic circuits on an unmodified home printer in under 3 minutes, writes eeNews Europe.

Perumal Varun Chadalavada and Gowtham Ramachandran from the University of Toronto were frustrated by the week-long wait between sending a printed circuit board (PCB) design for fabrication and receiving a prototype to test.

So they developed the Printem Film, a multilayer stack of different photosensitive materials that fits into a home printer to create the final copper circuit patter. Printing the circuitboard pattern on the Printem Film with a normal office printer creates a photo-mask that, when exposed to light from a laptop or phone, initiates a reaction that selectively "sticks" the copper to the substrate. When the user peels back the layers, the copper 'tears' in exactly the right pattern to create the final circuit, all in under three minutes and for US$15 to $20.

New security for LoRa IoT networks

By Nick Flaherty

Engineering firm Occam Technology Group has joined Syniverse’s recently launched Innovation Lab, which provides companies with a secure environment to test new technologies and business models for the internet of things (IoT), 5G, blockchain and artificial intelligence.

As part of this, Occam has created a new smart parking lot at Syniverse’s headquarters in Florida to demonstrate and test secure non-cellular IoT connectivity across a LoRa narrowband network. Sensors in the car park identify empty parking spaces and communicate the status of each space back to the Innovation Lab across a secure connection to the Syniverse Secure Global Access network.

“LoRa connectivity is often used in devices that are stationary in nature and rely on lower amounts of battery usage over an extended time span. Traditionally, while these connections have used minimal power, they have been vulnerable from a security perspective, so we are solving that challenge via our work with Occam,” said Michael O’Brien, Syniverse Group Vice President, Corporate Development and Strategy. “As the world’s most connected company, Syniverse offers an Innovation Lab that serves as a collaboration centre for service providers, cloud enablers and other businesses to develop IoT strategies and business models that are backed by secure connectivity.”

Occam designs and develops IoT solutions using multiple communication protocols with special expertise in non-cellular IoT LoRa connectivity for low-power, wide-area networks. The company incorporates radio transceivers into IoT devices and adds its gateway software to connect those devices into Syniverse’s Innovation lab across a secure connection to Syniverse Secure Global Access that mitigates the risks of cyberattacks by operating independently from the public internet.

LoRa technology enables wide signal coverage with low power usage that results in sensor batteries that only need to be maintained every five to 10 years, on average. This flexibility is proving increasingly important in scenarios with large volumes of fixed sensors, like monitoring agricultural crop production or for sensors located deep inside a building to monitor electricity or parking usage. In these cases, the sensors are not easily accessible and need to span larger geographic areas, so they must have long battery life with minimal required maintenance. At the same time, they cannot afford to risk exposure to cyberattack.

“IoT devices that connect via non-cellular LoRa networks are missing a security layer of protection, representing significant potential risk,” said Raymond Carr, Occam Technology Group’s Chief Technology Officer and founder. “Our collaboration with Syniverse is critical in providing the missing security component, so we can help businesses grow and maintain a hardened IoT infrastructure at scale.”
