Top 10 IoT technologies for the next two years


Gartner has revealed a list of the top technologies that will unlock the Internet of Things’ full potential in 2017 and 2018.


Fresh on the heels of CES and Mobile World Congress shows, Gartner has compiled a list of the top 10 Internet of Things technologies that should be on every company’s radar over the next two years. Among the key takeaways include security, device management and low-power, short-range networks. According to the firm, this handful of principles will have a broad impact on organizations, affecting everything from business strategy and risk management to a wide range of technical areas such as architecture and network design.

top-Internet-of-Things-technologies

So without further ado, Gartner’s top 10 IoT technologies for 2017 and 2018 are:

IoT Security

The IoT introduces a wide range of new security risks and challenges to the IoT devices themselves, their platforms and operating systems, their communications, and even the systems to which they’re connected. Security will be required to protect IoT devices and platforms from both information attacks and physical tampering, to encrypt their communications, and to address new challenges such as impersonating ‘things’ or denial-of-sleep attacks that drain batteries. IoT security will be complicated by the fact that many ‘things’ use simple processors and operating systems that may not support sophisticated security approaches.

IoT Analytics

IoT business models will exploit the information collected by ‘things’ in many ways, whether that’s understanding customer behavior, delivering services, or improving products. However, IoT demands new analytic approaches. These tools and algorithms are necessary now, but as data volumes increase through 2021, the needs of the IoT may diverge further from traditional analytics.

IoT Device (Thing) Management

Long-lived nontrivial ‘things’  will require management and monitoring. This includes device monitoring, firmware and software updates, diagnostics, crash analysis and reporting, physical management, and security management. The IoT also brings new problems of scale to the management task. Tools must be capable of managing and monitoring thousands and perhaps even millions of devices.

Low-Power, Short-Range IoT Networks

Selecting a wireless network for an IoT device involves balancing many conflicting requirements, such as range, battery life, bandwidth, density, endpoint cost and operational cost. Low-power, short-range networks will dominate wireless IoT connectivity through 2025, far outnumbering connections using wide-area IoT networks. However, commercial and technical trade-offs mean that many solutions will coexist, with no single dominant winner and clusters emerging around certain technologies, applications and vendor ecosystems.

Low-Power, Wide-Area Networks

Traditional cellular networks don’t deliver a good combination of technical features and operational cost for those IoT applications that need wide-area coverage combined with relatively low bandwidth, good battery life, low hardware and operating cost, and high connection density. The long-term goal of a wide-area IoT network is to deliver data rates from hundreds of bits per second (bps) to tens of kilobits per second (kbps) with nationwide coverage, a battery life of up to 10 years, an endpoint hardware cost of around $5, and support for hundreds of thousands of devices connected to a base station or its equivalent. The first low-power wide-area networks (LPWANs) were based on proprietary technologies, but in the long term emerging standards such as Narrowband IoT (NB-IoT) will likely dominate this space.

IoT Processors

The processors and architectures used by IoT devices define many of their capabilities, such as whether they are capable of strong security and encryption, power consumption, whether they are sophisticated enough to support an operating system, updatable firmware, and embedded device management agents. As with all hardware design, there are complex trade-offs between features, hardware cost, software cost, software upgradability and so on. As a result, understanding the implications of processor choices will demand deep technical skills.

IoT Operating Systems

Traditional operating systems such as Windows and iOS were not designed for IoT applications. They consume too much power, need fast processors, and in some cases, lack features such as guaranteed real-time response. They also have too large a memory footprint for small devices and may not support the chips that IoT developers use. Consequently, a wide range of IoT-specific operating systems has been developed to suit many different hardware footprints and feature needs.

Event Stream Processing

Some IoT applications will generate extremely high data rates that must be analyzed in real time. Systems creating tens of thousands of events per second are common, and millions of events per second can occur in some telecom and telemetry situations. To address such requirements, distributed stream computing platforms (DSCPs) have emerged. They typically use parallel architectures to process very high-rate data streams to perform tasks such as real-time analytics and pattern identification.

IoT Platforms

IoT platforms bundle many of the infrastructure components of an IoT system into a single product. The services provided by such platforms fall into three main categories:

  • Low-level device control and operations such as communications, device monitoring and management, security, and firmware updates
  • IoT data acquisition, transformation and management
  • IoT application development, including event-driven logic, application programming, visualization, analytics and adapters to connect to enterprise systems

IoT Standards and Ecosystems

Although ecosystems and standards aren’t precisely technologies, most eventually materialize as APIs. Standards and their associated APIs will be essential because IoT devices will need to interoperate and communicate, and many IoT business models will rely on sharing data between multiple devices and organizations.

Many IoT ecosystems will emerge, and commercial and technical battles between these ecosystems will dominate areas such as the smart home, the smart city and healthcare. Organizations creating products may have to develop variants to support multiple standards or ecosystems and be prepared to update products during their life span as the standards evolve and new standards and related APIs emerge.

The smart router is ready for IoT play


The evolution of router has reached the IoT’s doorsteps, and it raises some interesting prospects for industrial and smart home markets.


The router used to be largely a dumb device. Not anymore in the Internet of Things arena where node intelligence is imperative to make a play of the sheer amount of data acquired from sensors, machines and other ‘things.’ The IoT router marks a new era of network intelligence — but what makes a router smart?

owtbrd.png

For starters, it employs embedded hardware platforms with DIY capabilities while balancing the performance and power consumption requirements. Next, an IoT router provides the operational status on an LCD screen while manipulating the data from different interfaces. In human machine interface (HMI) applications, for example, a smart router offers LCD and touch screen interfaces on expansion I/Os.

Take the case of the DAB-OWRT-53 smart router, which is developed by the Belgian design house DAB-Embedded. The sub-100 euro device — based on Atmel’s SAMA5D36 processor and OpenWRT router hardware platform — is mainly targeted at smart home and industrial IoT applications.

The smart router of DAB-Embedded

The IoT router supports popular wireless interfaces such as Wi-Fi, ZigBee and Z-Wave, as well as a diverse number of wired interfaces including Ethernet, USB, CAN 2.0A/B, KNX and RS-232. And all the data from these interfaces can be stored in either microSD card or NAND flash.

Anatomy of Smart Router

The Atmel | SMART SAMA5D36 is at the heart of the smart router design. First and foremost, it optimizes power consumption in the battery-operated router that features 3.7V lithium polymer battery support with charging capability over a microUSB connector. The router boasts eight hours of battery lifetime while being in full ON mode with Wi-Fi communications.

Second, the ARM Cortex-A5 processor shows a robust performance in the communications domain. For instance, the SAMA5D36 implements routing functionality to transfer data from one Ethernet port to another in a way that router designers don’t require an external hardware hub or switch. Moreover, Atmel’s MPU offers greater flexibility to run a lot of embedded software packages such as OpenZWave and LinuxMCE.

Third, the SAMA5D36-based IoT router offers users the ability to manipulate firewall settings, Disable PING, Telnet, SSH and UPnP features. Furthermore, the hardware security block in SAMA5D3 processor allows the use of CryptoDev Linux drivers to speed up the OpenSSL implementation. The Wi-Fi module — powered by Atmel’s WILC3000 single-chip solution — also supports the IEEE 802.11 WEP, WPA and WPA2 security mechanisms.

The smart router of DAB-Embedded employs Active-Semi’s ACT8945AQJ305-T power management IC, but the real surprise is Altera’s MAX 10 FPGA with an integrated analog-to-digital converter (ADC). That brings the additional flexibility for the main CPU: Atmel’s SAMA5D36.

The FPGA is connected to the 16-bit external bus interface (EBI) so that IoT developers can put any IP core in FPGA for communication with external sensors. All data is converted inside the FPGA to a specific format by using NIOS II’s soft CPU in FPGA. Next, the SAMA5D36 processor reads this data by employing DMA channel over the high-speed mezzanine card (HSMC) bus.

An FPGA has enough cells to start even two soft cores for data preprocessing. Case in point: A weather station with 8-channel external ADC managing light sensors, temperature sensors, pressure sensors and more. It’s connected to the FPGA together with PPS signal from GPS for correct time synchronization of each measurement.

OpenWRT Framework

The SAMA5D36 embedded processor enables DAB’s smart router design to customize free OpenWRT Linux firmware according to the specific IoT application needs. The OpenWRT framework facilitates an easy way to set up router-like devices equipped with communications interfaces such as dual-port Ethernet and Wi-Fi connection.

What’s more, by using the OpenWRT framework, an IoT developer can add now his or her own application (C/C++) to exchange data with a KNX or Z-Wave transceiver. OpenWRT even supports the Lua embedded interpreter.

Next, while DAB-Embedded has built its smart router using the embedded Linux with OpenWRT framework, Belgium’s design house also offers a board support package (BSP) based on the Windows Embedded Compact 2013 software. That’s for IoT developers who have invested in Windows applications and want to use them on the new hardware: the DAB-OWRT-53 smart router.

Later, the embedded design firm plans to release smart router hardware based on the Windows 10 IoT software and Atmel’s SAMA5D family of embedded processors. The Belgian developer of IoT products has vowed to release the second version of its router board based on Atmel’s SAMA5D4 embedded processor and WILC3000 chipset that comes integrated with power amplifier, LNA, switch and power management. Atmel’s WILC3000 single-chip solution boasts IEEE 802.11 b/g/n RF/baseband/MAC link controller and Bluetooth 4.0 connection.

Atmel wireless connectivity supports industrial IoT revolution


The BTLC1000 exhibits the lowest BLE power consumption in the industry.


With both this year’s CES and Embedded World now behind us, it’ll be interesting to see which of the gadgets unveiled during these shows find a way to market — some will go to production, others won’t. I am skeptic about the smart shoe offering self-fastening mechanism… And during these two weeks, the IoT revolution has silently progressed in industrial automation. (You will be surprised if you read some very serious white papers extracted from the Internet of Things series published by Bosch.)

ble1000_google-banner.jpg

While attendees flocked to Vegas, progresses were made in industrial automation thanks to hard work being done in Germany. In fact, these two worlds — consumer oriented and industrial — are both relying on wireless connectivity, including products from Atmel: the ATWILC1000, ATWILC1500 or ATWILC3000 supporting Wi-Fi and ATBLC1000 supporting BTLE 4.1,which  was recently crowned “Product of the Year” from Electronic Products.

According to Bosch’s white paper “Leveraging the Internet of Things: Companies can streamline business processes for stakeholders across the extended enterprise,” we realize that Bosch’s managers have brainstormed about the IoT to extract the added business value for the enterprise, like for example, “in manufacturing, data automatically collected from smart and connected products, give companies meaningful feedback as to how products should be reengineered, and provides opportunities for additional revenue through selling services.”

In order to become smart and connected, industrial products need to integrate either a Wi-Fi connection supported by ATWINC1500, or a Bluetooth supported by the very tiny (see above) ATBTLC1000.

Shows the requirements for scalability on two current customer PoCs at Bosch Software Innovations. These PoCs start in year one with a very low umber of connected devices and sensors. However, in a short space of time, they scale massively upward for commercial launch and rollout.

From the above graphic, extracted from another white paper from Bosch, “Realizing the connected world-how to choose the right IoT platform,” we can derive two crucial information. The first is the fact that IoT is already a reality in the industrial market segment, not really known to be fashion driven like could be consumer electronic. The second information is about scalability. In both examples, the number of connected devices was very low, but in a short space of time they scale massively, reaching 500k devices for the first and up to 3 million for the other. A single industrial automation application can generate a very good semiconductor business, including sensors, MCU and wireless connectivity device. In our previous blog, we have investigated the ATWINCxx00 family bringing Wi-Fi connectivity to any embedded design. Let’s take a look at the award winner ATBTLC1000 device supporting BT 4.1 connectivity.

Atmel's BTLC1000

The BTLC1000 is an ultra-low power Bluetooth SMART (BLE 4.1) SoC with an integrated ARM Cortex-M0 MCU, a transceiver, a modem, MAC, PA, TR Switch, and a power management unit (PMU). It can be used as a BLE link controller or data pump with external host MCU, or as a standalone applications processor with embedded BLE connectivity and external memory. If we look at the key features list:

  • BLE4.1 compliant SoC and protocol stack
  • Lowest BLE power consumption in industry
  • Smallest BLE 4.1 SoC — Available in WLCSP (2.26×2.14mm) or QFN ( 32p 4×4 mm)
  • Optimized system cost — High level of integration on chip reduces external Bill of Material significantly
  • Wide operating Voltage range — 1.8 – 4.3V
  • Host Interface — SPI or UART
  • Certified modules — FCC, ETSI/CE, TELEC
  • Enterprise Development support & tools with the ATBTLC1000 Xplained Pro

The main reasons why the Atmel BTLC1000 has won the Electronic Design award are power, cost and certification. This chip not only exhibits the lowest BLE power consumption in the industry, it’s also the smallest BLE 4.1 SoC (see picture) offering optimized system cost, thanks to high level of integration. If companies like Bosch supporting industrial automation segment for years (if not centuries) start to be seriously involved into smart connected IoT systems, no doubt that ATBTLC1000 and ATWILC1000 devices have a bright future…

Atmel launches the industry’s first hardware interface library for TLS stacks used in IoT edge node apps


The new HW-TLS platform provides an interface between software TLS packages and the ATECC508A cryptographic co-processor.


With the rise of the Internet of Things, security has become a pressing topic because autonomous remote devices are now routinely connecting to wireless networks to form complex smart device and cloud-service ecosystems. As a result, autonomous IoT gadgets constitute a significant part of those networks and must be able to authenticate themselves to the network resources to maintain the integrity of the ecosystem. In addition, these remote, resource-constrained clients must be able to perform this authentication using minimal processing, memory and power.

Cognizant of this, Atmel has launched the industry’s first hardware interface library for TLS stacks used in Internet of Things edge node applications. Hardening is a method used for reducing security risks to a system by applying additional hardware security layers and eliminating vulnerable software. This new Hardware-TLS (HW-TLS) platform provides an API that allows TLS packages to utilize hardware key storage and cryptographic acceleration even in resource constrained edge node designs. HW-TLS is a comprehensive solution pre-loaded with unique keys and certificates designed to eliminate the complexities of generating secure keys in the manufacturing supply chain.

OpenSSL is a general-purpose cryptography library that provides an open source implementation of the Secure Sockets Layer (SSL) and TLS protocols. wolfSSL is a cryptography library that provides lightweight, portable security solutions with a focus on speed and size. Atmel’s new ATECC508A-OpenSSL and ATECC508A-wolfSSL are available for immediate download at their respective software distribution repositories, offering seamless adoption of more secure elements without disruption to the developer workflow.

OpenSSL

Secure hardening for both OpenSSL and wolfSSL is made possible with HW-TLS which enables those TLS software packages to interface seamlessly with the ATECC508A CryptoAuthentication co-processor. This IC provides protected key storage as well as hardware acceleration of Elliptic Curve Cryptography (ECC) cipher suites including mutual authentication (ECDSA) and Diffie-Hellman key agreement (ECDH). As such, HW-TLS allows developers to substantially harden Transport Layer Security (TLS), enhancing security for IoT ecosystems.

When used together, HW-TLS and the ATECC508A let even extremely small, low-cost IoT nodes implement strong cryptographic security. All private keys, certificates and other sensitive security data used for authentication are stored in secure hardware and protected against software, hardware and back-door attacks. Beyond that, the integrated ECC accelerators in the ATECC508A offload cryptographic code and math from the MCU allowing even a low-end processor to perform strong authentication.

ATEC

“Everyone with an interest in IoT security should be excited about Atmel HW-TLS with wolfSSL,” explains Larry Stefonic, wolfSSL CEO. “The combination of our secure software and Atmel’s new chips brings TLS performance and security to a level unrivaled in the industry. Atmel’s HW-TLS platform also makes it easier than ever for developers to incorporate truly hardened security into our TLS stack.”

Traditionally, TLS performed authentication and stored private keys in software. However, Atmel’s latest platform closes the vulnerability gap in this arrangement by offloading the crucial key management responsibility to dedicated, tamper-resistant secure elements such as the ATECCC508A crypto engine. What’s more, the intensive crypto algorithms are processed in the CryptoAuthentication device, offloading the MCU on the remote devices and enabling the IoT edge node to authenticate to the cloud without a user-perceptible delay. Furthermore, Atmel Hardware-TLS comes as a complete platform pre-loaded with unique keys and certificates for eliminating the complexities of adding secure keys to each device in a manufacturing supply chain.

“With more and more remote devices being connected to the cloud every day in the era of the IoT, it becomes increasingly critical to ensure these devices are not vulnerable to attack,” adds Nicolas Schieli, Senior Director of Atmel’s Secure Products Group. “Such devices can be entirely secure only when they are hardware secure, meaning the ‘secret’ keys are stored in a separate hardware unit. We are excited to bring this innovation to market, enabling device manufacturers that need to connect to the cloud to take advantage of hardware security.”

Cry

The Hardware-TLS complements Atmel Certified-ID, a seamless and secure keys provisioning platform for assigning trusted identities to devices joining the IoT.

New gateway will connect billions of Bluetooth devices to the IoT


The Bluetooth SIG’s new architecture and toolkit will enable developers to create Internet gateways for Bluetooth products.


The Bluetooth Special Interest Group (SIG) just introduced a new architecture and supporting set of educational tools that enables developers to quickly create Internet gateways for Bluetooth products.

These gateways allow any Bluetooth sensor to relay data to the cloud and back again. This architecture expands the potential functionality of the IoT by giving anyone the ability to monitor and control fixed Bluetooth sensors from a remote location, whether that’s turning off their lights while away or unlocking their front door for a pet sitter.

luet.png

The Bluetooth Internet gateway architecture and toolkit show developers, Makers, hackers and OEMS how to quickly and simply create a connection between Bluetooth and the cloud without the need for a smartphone or tablet to serve as the middleman. This essential communication capability is the next step to enabling the IoT by giving people and systems control of sensors regardless of proximity.

The new architecture will meet an immediate need for smart home developers looking to create a hub for all the sensors in a home or to integrate gateway functionality into existing products. It couldn’t come at a better time either. A recent report has revealed that out of the 4.5 million people identified as IoT developers in 2015, 1.4 million of them were focused on building smart home applications.

“People want to monitor their home security system from their couch and office. The Bluetooth Internet gateway architecture provides a standard way for any developer to create this gateway functionality. Routers, thermostats, security systems – the always on, always connected infrastructure in the home – can now speak to and control tiny, low power sensors and relay that information to the cloud, providing control from anywhere,” explains Steve Hegenderfer, Director of Developer Programs.

This architecture is part of Bluetooth SIG’s bigger play to grow throughout the IoT and home automation markets. Plus, it will help them extend the range of Bluetooth data transfers beyond the wireless range of Bluetooth itself.

“The key value promised by the IoT is that we can make life a little better by linking technologies and giving people more knowledge and control,” said Errett Kroeter, Bluetooth SIG VP of marketing. “Our new Bluetooth gateway architecture enables the IoT to do just that. We are extending the monitoring and control of Bluetooth enabled sensor devices to the cloud and making the data accessible.”

Beast

Fabulous Beasts is like Jenga with an IoT twist


Fabulous Beasts is a game of strategy and balance in which you build a tower of animals on your tabletop, then help them evolve in a connected digital world.


Video games have come a long way in the past several years, yet they’ve also increased children’s fascination with screened devices. And unfortunately, alternatives like board and card games seem to lack the high-tech pizzazz kids are looking for these days. This was a problem London-based studio Sensible Object wanted to solve.

press-gallery-1

Fabulous Beasts is the startup’s first game, which combines the physical interaction of old-school fun with today’s digital savviness. Inspired by the Internet of Things, players take turns in constructing a Jenga-like tower by balancing multi-colored, animal-shaped blocks on top of each other.

Similar to popular games like Disney Infinity and Skylanders, Fabulous Beasts is hoping to bridge the gap between the physical and virtual worlds, all while creating a deeper and more dynamic experience for the younger generation.

The game itself is made for one to five players, each of whom become “gods” ruling over an app-connected world, visible on any phone or tablet over Bluetooth. Before each turn, players scan their RFID-embedded game pieces, also known as “Beast Artefacts,” via a reader and then place them atop the stack. As this happens, the animals will appear on the mobile device, and evolve and augment in interesting ways.

As time goes on, the tower becomes taller and more complex, and consequently worth more points. The objective is get the highest score (or fabulousness) before the tower eventually falls down. Once this occurs, just like Jenga, the game comes to an end.

What’s more, Fabulous Beasts is a fine example of a project that has transcended from beyond the MakerSpace and into the MarketPlace, having originally prototyped with 3D printing and Arduino. The studio is now launching a crowdfunding campaign to draw attention from the public.

Novi is a 4-in-1 DIY home security system


Say goodbye to contracts, monthly fees and false alarms.


Did you know that four burglaries occur every minute in the United States alone? That’s a startling one every 15 seconds. The good news is that most convicted burglars (90%) claim they want to avoid homes with alarm systems, saying that if they did encounter an alarm, they would abandon the attack. However, the bad news is that nearly two-thirds of homeowners fail to turn it on at all times. And, when it comes to security, many are often faced with expensive systems and pricey monitoring fees. Understandably so.

12471337_1222782587738909_6064261952724678011_o

However, one Provo, Utah-based startup is looking to change that with their new IoT solution. Novi Security is a 4-in-1 DIY security system that’s making it increasingly easier for homeowners to install small detectors throughout their house that can notify them of any motion or smoke — all without the need of contracts and monthly costs!

Seurit

The kit is comprised of a base station and sensors, and are equipped with an ATmega128 radio and an Atmel | SMART SAM4S processor. The battery-powered sensors are simply affixed to the ceiling and boast an HD camera, motion and smoke detectors, and siren. This allows the system to provide homeowners a peace of mind by sending a series of three photos right to their mobile device, while immediately emitting a siren if smoke or motion are recognized while away.

SmartphoneNovi

In the event that this occurs, the alarm will sound, the monitor will relay the images to the base station (plugged directly into a router), and the base station will transmit the photos over to an accompanying app. Once the alert is received on the smartphone, the user will then have the option to call for help, check in at home, arm/disarm, as well as request more pictures for greater clarity.
