By Nick Flaherty www.flaherty.co.uk

 ZTE is boosting its move to dominate the Internet of Things through a deal with Intel.

The company aims to use 5G as a key technology, and the two will set up an innovation lab for research and development of future key IoT technologies, including experimental verification, evaluation and research and development of related technologies.
The two have previously cooperated in many fields, such as IoT access technologies, open-source collaboration, IoT platforms and solution integration.

"In Intel’s vision, 5G will bring us a smarter Internet and deliver a world of connectivity in a more flexible, effective and cheaper way. We are looking towards the infinite possibilities that come from 50 billion smart devices and Intel and ZTE will make joint efforts for the IoT lab," said Rose Schooler, Vice President of Intel’s Sales Group and General Manager of Intel Global Internet of Things Sales. "We will create a new generation of IoT solutions for promoting the construction of an IoT application ecosystem as well as the development and prosperity of the IoT industry."

"IoT is not only an important part of the ‘Made in China 2025’ plan and the Internet+ strategy, but also an important way to promote China's industrial advancement and economic revitalisation," said Chen Jie, CIO of ZTE. "ZTE actively explores business models, and is focusing on creating two major support platforms: an IoT ecosystem platform and capital platform. I am very pleased with the progress Intel and ZTE are making in the IoT field in joint R&D and the construction of the IoT Innovation Lab.

Arqiva and Samsung test out early fixed 5G technology in the UK

By Nick Flaherty www.flaherty.co.uk

The race to provide 5G for the Internet of the Things is hotting up as Arqiva is set to test out the technology in London using kit from Samsung.

This will be the first field trial of 5G Fixed Wireless Access (FWA) technology in the UK as an alternative to fibre. The preliminary 5G standard was published last week, and the UK will publish its 5G strategy 'shortly'.
The trial is set to take place in the second half of 2017 in central London and will involve the deployment of an end-to-end 5G FWA network, operating in the 28GHz band. Arqiva owns the national license in the UK for this spectrum, which is also the standard band being used for 5G trials in the USA, Japan and South Korea.

“Arqiva delivers millions of vital connections in the UK every day and we have been watching the development of 5G very closely. Our experience of running critical communications networks places us in a strong position, alongside a number of our operator customers, to take the lead in shaping how this country prepares itself for the introduction of 5G," said Simon Beresford-Wylie, CEO Arqiva. “5G will be a crucial pillar of the UK’s economy in the 2020s. It will provide higher speeds: 1Gbps and significantly reduced latency (delay), along with super high reliability for mission critical applications. Mobile video streaming and virtual reality will be key applications with customer usage of c100GB per month being the norm vs c1-5GB per month at present. Over time, smarter network infrastructure and an enhanced ability to support exponential scale for connectivity will open the doors to further applications across a variety of markets such as IoT, industrial applications and the full promise of autonomous vehicles.
“Our existing network of infrastructure assets, including mobile masts and street furniture, will be essential to providing the network over which 5G will be delivered by MNOs across the UK. Our trial with Samsung will demonstrate the enormous potential of 5G FWA as an alternative to fibre for delivering ultra-high speed connectivity to homes and businesses.”
Samsung’s 5G Access Units (the base stations) will use the 28GHz millimeter wave spectrum and beam-forming to provide high-density coverage and ultra-high-bandwidth connectivity to CPEs (or Customer Premise Equipment) installed in nearby locations. These can be self-installed, reducing costs, and can bring a subscriber online in a matter of minutes. This gives 5G FWA considerable advantages over comparable FTTH or FTTB (Fibre-to-the-Home/Building) deployments in terms of service rollout times and the costs to both the service provider and the subscriber.
The CPEs will be based at locations in London including Arqiva’s offices at Percy Street, London W1 and will provide ultra-high speed connectivity to multiple devices. The locations will be selected because of the wide range of customer groupings in business and residential premises.
“With advanced news of 5G trials already being made in the US and Korean markets, we are really excited to be partnering with Arqiva to jointly demonstrate just how important the UK and Europe is to the 5G revolution," said Thomas Riedel, Head of Samsung Networks Europe.
"The Government wants the UK to be a world leader in 5G and we're already laying the foundations for a successful launch. We are investing £1bn to boost the UK’s digital infrastructure and support 5G trials, and will shortly be publishing our 5G strategy," said the governent's Culture Secretary, Karen Bradley MP. "But industry will continue to play the leading role, and investments like Arqiva's will help make sure the UK gets the benefits of new 5G networks early on, including faster, more reliable connections, new services like connected cars and the Internet of Things."

King Cobra rugged server design provides a “total rack” in only 2U


While it is not itself an embedded component, the S2U 'King Cobra' rack server highlights the best in embedded system design writes Nick Flaherty .


The S2U developed by General Micro Systems (GMS) can replace up to 15U of equivalent server rack functions by using a modular and scalable architecture that is a breakthrough in electro-mechanical design. Each sub-system is optimized for maximum performance, lowest power, highest efficiency thermal profile and modular replacement in the field. Each subsystem is scalable and upgradable to lower the total cost of ownership (TCO) over the life of the system.

With more and more computing resources needed in the data centre to support the Internet of Things, a compact, scalable rack that can add multiple accelerators is a key technology.

The design starts with the field-removable OpenVPX single-board computer (SBC) motherboard with dual 18 core Intel Xeon E5-2600v4 CPUs and up to 1024GB (1TB) of DD4 DRAM, supported with a completely PCI Express-based storage subsystem with up to 48TB of solid state disks.

The 17-inch deep short rack includes a 24 port (22x 1GigE; 2x 10GigE) Ethernet switch subsystem, a hardware or enterprise-class Cisco intelligent router, two Power Supply Unit (PSU) options with Auxiliary Power Unit (APU), and scalable add-in modules for algorithm coprocessors, sensor interfaces, additional I/O or legacy system interfaces. On-board removable smart fan trays finely manage airflow and noise using side-mounted inlet/outlets.

“This server is not what everyone else is doing. It’s a revolutionary concept in server design,” said Ben Sharfi, GMS CEO and Chief Architect. “We looked at the entire rack, identified the functions most needed in a rugged system—from the server to the switch, and from backup power in our patent-pending APU to the existing system I/O—and designed a ‘total rack’ into a 2U, 17-inch deep box. It’s a future way of thinking about a server solution to the problem.” 

S2U King Cobra has been awarded or has pending a total of 12 patents. “If it wasn’t unique,” said Sharfi, “the patents wouldn’t have been issued. No server company is even close to this technology, nor will be in the near future.” The patents include the Xeon CPU sockets and PCIe interconnects as well as the distributed airflow that is managed via 12 individual smart fans with tachometers, to the 100 percent only-12Vdc internal power buses that eliminate the inefficiencies of typical server power supplies with standard (and often unneeded) multi-voltage power rails and up/down converters.

The OpenVPX motherboard is also designed by GMS and based upon a proven GMS compute-engine design that is used in defence applications, with the CPUs cooled via a patented version of the company’s RuggedCool technology; the heatsinks are also custom designed for maximum thermal transfer to the finely managed in-box airflow. Dual hot-swappable fan trays each contain six smart fans which blow air in/out of the system to the side—not the front/rear as in typical servers. The side-facing fans operate based upon real-time cooling needs using input from in-system sensors. The advantage of this system is that it minimizes fan noise to the server environment by keeping the fans at the minimum speed to cool the system.

Internal PCIe buses move data to the subsystems, including the 12-tray drive network-attached storage array.  While the system supports traditional SATA and SAS SSDs (up to 4TB per tray), S2U is best used with PCIe-based NVMe drives that provide a direct PCIe path between CPU and storage, eliminating the typical server drive controllers that rob performance by converting from PCIe to another interface and protocol.

The advantage of this architecture is that a hardware RAID controller isn’t needed. Instead, Intel’s CPUs support RSTe and RST2 software RAID to directly control NVMe drives without performance penalty. With 12 drive trays available, S2U supports up to 48TB of SSD storage with performance of well over 20X better than standard SAS/SATA drives. 

Traditional servers have minimal ability to add-in specialty I/O or co-processors. While there may be one or two PCIe card slots for off-the-shelf modules, this is rarely sufficient for systems interfacing with multiple legacy I/O interfaces. S2U offers four different ways to add up to 25 I/O and co-processors:

1) 4x PCIe x16 card slots
2) 3x 3U OpenVPX defence-quality modules
3) GMS’s SAM I/O (miniPCIe) on each drive tray and on the 6U VPX modules
4) Defence-quality XMC card can be added to the OpenVPX SBC motherboard

This allows the S2U to support up to 24 TFLOPS of arithmetic processing via just two Nvidia Quadro P6000 processor GPGPU compute engine modules.



The S2U includes two ways to the power the system: via the three N+1 3U OpenVPX power supplies or via the add-in PSU/APU. The PSU/APU replaces the PCIe card cage and provides battery power to allow orderly suspend-to-disk or shutdown. Regardless of which option the user selects, the power supply is optimized for maximum efficiency. All S2U internal power buses are +12VDC, eliminating the need for multiple in-system power converters. This dramatically differs from traditional servers that use commodity “black box” power supplies with multiple (often unneeded) voltage outputs. S2U’s power distribution system gets the energy where it is needed without superfluous power rails.

Finally, the S2U is designed to be more than a high-performance server with NAS and scalable I/O. There’s also a 22-port intelligent managed Layer 2/3 Ethernet switch with POE+ on all ports, plus an additional four 10GigE ports (SBC plus switch).

Tri-mode chips become a thing


By Nick Flaherty www.flaherty.co.uk

Qualcomm Technologies is launching a System-on-chip (SoC) device for the Internet of Things (IoT) that combine three key wireless technologies -  Bluetooth Low Energy 5, Dual-band Wi-Fi, and 802.15.4 ZigBee and Thread.

The tri-mode QCA4020 has a dedicated ARM Cortex M4 processor core for customer applications aongside a low power ARM Cortex M0 core for Bluetooth Low Energy drivers and 802.15.4 control and security functions. It also supports the CSRmesh mesh networking capability which Qualcomm acquired with Cambridge Silicon Radio in 2015.

A smaller dual mode chip, the QCA4024, integrates Bluetooth Low Energy 5 and 802.15.4 without the WiFi. 
Both use Qualcomm's Network IoT Connectivity Platform, including  coexistence across technologies with pre-integrated support for HomeKit and the Open Connectivity Foundation (OCF) specifications, as well as support for AWS IoT software development kit (SDK) and Microsoft Azure Internet-of-Things (IoT) Devices SDK to connect with Azure IoT Hub. 

With the surge of connected devices in the home and public places, implementing security features for IoT device attacks is a challenge felt industry-wide. Qualcomm Technologies has a strong foundation in device security that stems from our experience with mobile platforms and therefore is uniquely positioned to support IoT security based solutions to help address vulnerabilities and provide advanced security features for devices. The QCA4020 and QCA4024 both have hardware-based security with secure boot, trusted execution environment, encrypted storage, key provisioning and wireless protocol security. This gives OEMs the option of replacing external security chips and potential for bill of materials (BOM) savings.

“Qualcomm Technologies is bringing new interoperability for IoT and addressing ecosystem fragmentation by offering multiple radio, standards, protocols and connectivity framework support on a single-chip solution. This is a game-changer for manufacturers and consumers alike,” said Raj Talluri, senior vice president, product management at Qualcomm Technologies. “The addition of our industry-leading hardware security features allows manufacturers and developers to support applications including smart cities, toys, home control and automation, networking and home entertainment and offer their customers more advanced security that are cost effective.”

These solutions can be used to integrate Bluetooth Low Energy 5, Wi-Fi and 15.4 connectivity capabilities across the Qualcomm Network range of solutions complementing portions of the product portfolio beyond IoT devices, such as the recently announced IPQ8074 and QCA6290

The QCA4020 and QCA4024 are sampling with select OEMs today and expected to be commercially available in the second half of 2017.

    STM32 evaluaton boards for long-range IoT connections

    By Nick Flaherty www.flaherty.co.uk

    STMicroelectronics has launched two ready-to-use prototype boards to evaluate LoRaWAN and other Low-Power Wide Area Network (LPWAN) technologies including 6LoWPAN for long range connection sin the Internet of Things. 

    The boards are based on the smallest and lowest-power LoRaWAN modules that exist on the market today, with a footprint not larger than 13x12mm and current consumption of 1.2µA in standby mode.
    The B-L072Z-LRWAN1 STM32 LoRa Discovery kit ($46.50) builds on the all-in-one open module from Murata that integrates a STM32L072CZ microcontroller (MCU) and Semtech SX1276 transceivers. The module features a LoRa modem that provides ultra-long-range spread-spectrum communication and high interference immunity whilst minimizing current consumption.

    Since the module is open, developers have access to the STM32L072 MCU and its peripherals such as ADC, 16-bit timer, LP-UART, I2C, SPI and USB 2.0 FS (supporting BCD and LPM). Applications use the STM32L0 HAL and LL embedded software libraries, and designers can further extend the board’s functionality choosing from expansion boards within the STM32 Nucleo ecosystem or Arduino expansion boards.

    The B-L072Z-LRWAN1 kit includes an on-board debugger, a 64-pin STM32 Nucleo morpho connector, an Arduino-compatible connector, and a battery socket. It also comes with access to a completely free development ecosystem that includes the MDK-ARM Integrated Development Environment (IDE), STM32CubeMX configurator and software tools, and ST’s LoRaWAN protocol stack (I-CUBE-LRWAN).

    The I-NUCLEO-LRWAN1 ($25.00) is an expansion board for STM32 Nucleo or Arduino boards that can be simply plugged in to quickly start work developing a full LoRa-based and/or FSK/OOK (Frequency-Shift Keying/On-Off Keying) connectivity applications. The board features a LoRaWAN module from USI together with an STM32L052T8 MCU and Semtech SX1272 transceivers.

    The USI module comes pre-loaded with an AT command stack that helps streamline development and saves programming. The I-CUBE-LRWAN stack is available free of charge. As an extra bonus, to aid development of Internet-of-Things (IoT) applications, the I-NUCLEO-LRWAN1 board is also equipped with ST’s LIS2DS12 3-axis accelerometer, LPS22HB MEMS pressure sensor, and HTS221 humidity-and-temperature sensor.

    Both boards are LoRaWAN-certified and fully compliant with wireless regulations in the US, EU, Russia, India, and other countries using the 860-930MHz frequency bands. In addition to the industry-standard protocols, they also support proprietary LPWAN protocols for long-range connection of IoT devices like smart meters, alarm systems, tracking devices, positioning devices, environmental sensors, and activity sensors.

    The B-L072Z-LRWAN1 Discovery kit and I-NUCLEO-LRWAN1 are ready for distributors to order now, and will be available via st.com by the end of this month.

    Microsoft Azure signs up another global IoT network

    By Nick Flaherty www.flaherty.co.uk

    Microsoft has picked up another potentially large Internet of Things (IoT) deployment for its Azure cloud service in a deal with Ingenue.

    Ingenue will use the Azure IoT Hub for its end-to-end IoT networks using its Random Phase Multiple Access (RPMA) low power network technology. This uses globally available spectrum for M2Mand IoT long range links. It enables devices to connect more efficiently and cost-effectively in both the uplink and downlink and requires less towers to provide coverage to large areas (1:10 to 1:30 radio towers for RPMA vs. cellular) and has been used in 38 networks so far.
    Azure IoT Hub supports a broad set of operating systems and protocols, giving IoT solution developers the ability to quickly connect, monitor and manage IoT assets. Ingenu’s Intellect RPMA device management platform, will integrate with the Azure IoT Hub to provide secure bi-directional communication between RPMA-enabled devices and web applications. The solution will further enhance the processing of collected IoT data using Azure services such as Stream Analytics, SQL Database, Event Hubs, App Service, and Power BI Embedded.

    “The inherent characteristics of the Microsoft Azure cloud platform spurred the seamless development of this innovative solution,” said Joshua Builta, vice president, product management at Ingenu. “The Microsoft and Ingenu application teams collaborated to create an extremely simple and useful tool which extends the capabilities of the Intellect platform.”

    “This integration enables complete network visibility and an end-to-end robust data management solution,” said Sam George, Director, Microsoft Azure IoT at Microsoft.

    Shop windows to become screens - video

    By Nick Flaherty www.flaherty.co.uk



    Panasonic will start shipping its high image contrast transparent screen that enables the use of glass, such as shop windows, as digital signage next month.

    The system includes a unique glass (XC-CSG01G) with a high contrast light control film placed in between two sheets of glass, which when voltage is applied changes from the screen mode to the transparent mode, as well as the XC-CSC01G-A1 control box. 

    Images are projected (from the rear) onto the glass during the screen mode. The control box will synchronously operate the projector and the screen per the image content, and change the screen from transparent mode to screen mode. During the transparent mode, it will serve as a shop window showcasing products and exhibits, and during the screen mode it can reproduce high resolution images on the glass to introduce information about new products or about various campaigns during the sale season, helping transform the show window into an even more captivating environment. Multiple screens may be combined to create one large screen to create 

    Traditionally, images have been projected onto cloudy white, electric switchable glass, but this type of glass was incapable of displaying high contrast images due to image degradation caused by external light.



    Panasonic has combined glass with a high contrast light control film, which is comprised of a transparent-cloudy white switching layer containing special polymers and capsules and a color hue control layer. The color hue control layer will absorb a great deal of external light in screen mode, thereby significantly reducing image degradation and bringing to life high contrast images on par with digital signage, even in brightly lit environments.

    By adjusting the colour hue control layer's permeability depending on the level of lighting in the installation environment, the screen can maintain the same level of high contrast in environments of varying brightness. In brightly lit spaces, it can reproduce images with rich blacks, and in dark environments, it can reproduce high contrast images even with a compact projector.

    Numerous screens may be combined horizontally, so for example, a 221-inch (16:9) screen measuring 4.9m wide and 2.75m tall can be created. The control box will switch between transparent and screen modes, control the projector, and turn ON/OFF the lighting in the exhibition space behind the glass.

    The company has been working on this type of technology for several years:  Panasonic gives 3D gesture control to outdoor signs and industrial apps - video


    Picowatt switch slashes standby power

    Researchers at the University of Bristol have developed an ultra-low power switch that operates from a few picowatts, allowing sensors in the Internet of Things (IoT) to save power and cut standby power to zero.

    The voltage detector chip uses five picojoules of energy and requires only around half a volt to operate, which can be delivered directly from a sensor such as a photodetector. This would cut standby power to zero.

    Gartner predicts 8.4bn connected devices in the IoT in 2017
    Four trends driving IoT in 2017

    The research group are providing samples of their chip to companies to use, and the team have demonstrated a TV with no continuous draw of power during standby by using a voltage detector that is powered up at a distance, directly from the infrared signal of a standard TV controller.

    “The ultra-low power UB20M voltage detector provides sensing that is continuous and free," said Dr Stark, Reader in Electrical & Electronic Engineering in the Department of Electrical & Electronic Engineering. "This is because it is able to respond to minute quantities of power from unpowered sensors. No battery or other power is needed for the device to stay alive and listening, and battery maintenance is therefore reduced or not needed.  We are now actively seeking commercial partners to use the voltage detector chip in their product, and would welcome companies to get in touch."

    Flexible solid state battery just 0.25mm thick opens up embedded design options

    By Nick Flaherty www.flaherty.co.uk


    A $1.5m collaborative project is set to develop and produce a flexible, solid-state lithium battery that is just 0.25mm thick. By integrating an ultra-thin flexible ceramic substrate, more embedded design options open up.

    The FlexTech consortium, set up by the SEMI semiconductor industry association, is working with ITN Energy Systems of Colorado on the 15 month project to produce a 500mAh cell no larger than 50 x 27 mm and just 0.25mm thick, says Brian Berland, chief science officer at ITN. The ceramic substrate is produced by ENrG of Buffalo, NY,  which licenses the technology from Corning.
    “This work will break new ground in flexible battery development and address the many challenges associated with this area,” said Melissa Grupen-Shemansky, chief technology officer for FlexTech | SEMI.  “This technology is one of the most promising for multi-cell packages and infinitely-expandable battery components.”
    An important part of the project is selecting a sealing material based on compatibility with the assembly process and the ultimate performance of the battery. “This new approach to flexible power supplies promises up to 10x the capacity with one-half the thickness of products currently in the market,” said Berland. “Once completed, we believe that rapid market adoption of this product is highly likely, since power availability and management is a significant bottleneck to many innovative FHE products.”

    Gartner predicts 8.4bn connected devices in the IoT in 2017

    By Nick Flaherty www.flaherty.co.uk

    Market researcher Gartner is predicting that 8.4 billion connected things will be in use worldwide in 2017, up 31 percent from 2016, and will reach 20.4 billion by 2020. Total spending on endpoints and services will reach almost $2 trillion in 2017. 
    Regionally, Greater China, North America and Western Europe are driving the use of connected things and the three regions together will represent 67 percent of the overall Internet of Things (IoT) installed base in 2017.
    Consumer Applications to Represent 63 Percent of Total IoT Applications in 2017
    The consumer segment is the largest user of connected things with 5.2 billion units in 2017, which represents 63 percent of the overall number of applications in use (see Table 1). Businesses are on pace to employ 3.1 billion connected things in 2017. "Aside from automotive systems, the applications that will be most in use by consumers will be smart TVs and digital set-top boxes, while smart electric meters and commercial security cameras will be most in use by businesses," said Peter Middleton, research director at Gartner.

              In addition to smart meters, applications tailored to specific industry verticals (including manufacturing field devices, process sensors for electrical generating plants and real-time location devices for healthcare) will drive the use of connected things among businesses through 2017, with 1.6 billion units deployed. However, from 2018 onwards, cross-industry devices, such as those targeted at smart buildings (including LED lighting, HVAC and physical security systems) will take the lead as connectivity is driven into higher-volume, lower cost devices. In 2020, cross-industry devices will reach 4.4 billion units, while vertical-specific devices will amount to 3.2 billion units.
              Business IoT Spending to Represent 57 Percent of Overall IoT Spending in 2017
              While consumers purchase more devices, businesses spend more. In 2017, in terms of hardware spending, the use of connected things among businesses will drive $964 billion (see Table 2). Consumer applications will amount to $725 billion in 2017. By 2020, hardware spending from both segments will reach almost $3 trillion.

              Total IoT services spending (professional, consumer and connectivity services) is on pace to reach $273 billion in 2017. These are dominated by the professional IoT-operational technology category in which providers assist businesses in designing, implementing and operating IoT systems. However, connectivity services and consumer services will grow at a faster pace. Consumer IoT services are newer and growing off a small base. Similarly, connectivity services are growing robustly as costs drop, and new applications emerge.
