Tiny, Rugged IoT Gateways Offer 10-Year Linux Support

By Eric Brown

Moxa has announced the UC-2100 Series of industrial IoT gateways along with its new UC 3100 and UC 5100 Series, but it offered details only on the UC-2100. All three series will offer ruggedization features, compact footprints, and on some models, 4G LTE support. They all run Moxa Industrial Linux and optional ThingsPro Gateway data acquisition software on Arm-based SoCs.

 

Moxa UC-2111 or UC-2112 (left) and UC-2101 (click image to enlarge)

Based on Debian 9 and a Linux 4.4 kernel, the new Moxa Industrial Linux (MIL) is a “high-performance, industrial-grade Linux distribution” that features a container-based virtual-machine-like middleware abstraction layer between the OS and applications,” says Moxa. Multiple isolated systems can run on a single control host “so that system integrators and engineers can easily change the behavior of an application without worrying about software compatibility,” says the company.

MIL provides 10-year long-term Linux support, and is aimed principally at industries that require long-term software, such as power, water, oil & gas, transportation and building automation industries. In December, Moxa joined the Linux Foundation’s Civil Infrastructure Platform (CIP) project, which is developing a 10-year SLTS Linux kernel for infrastructure industries. MIL appears to be in alignment with CIP standards.

Diagrams of ThingsPro Gateway (top) and the larger ThingsPro eco-system (bottom) (click images to enlarge)

Moxa’s ThingsPro Gateway software enables “fast integration of edge data into cloud services for large-scale IIoT deployments,” says Moxa. The software supports Modbus data acquisition, LTE connectivity, MQTT communication, and cloud client interfaces such as Amazon Web Services (AWS) and Microsoft Azure. C and Python APIs are also available.

 

Moxa’s UC-3100 (source: Hanser Konstruktion), and at right, the similarly Linux-driven, ThingsPro ready UC-8112 (click images to enlarge)

Although we saw no product pages on the UC-3100 and UC-5100, Hanser Konstruktion posted a short news item on the UC-3100 with a photo (above) and a few details. This larger, rugged system supports WiFi and LTE with two antenna pairs, and offers a USB port in addition to dual LAN and dual serial ports.

The new systems follow several other UC-branded IoT gateways that run Linux on Arm. The only other one to support ThingsPro is the UC-8112, a member of the UC-8100 family. This UC-8100 is similarly ruggedized, and runs Linux on a Cortex-A8 SoC.

UC-2100

The UC-2100 Series gateways runs MIL on an unnamed Cortex-A8 SoC clocked at 600MHz except for the UC-2112, which jumps to 1GHz. There are five different models, all with 9-48 VDC 3-pin terminal blocks and a maximum consumption of 4 Watts when not running cellular modules.

The five UC-2100 models have the following dimensions, weights, and maximum input currents:

  • UC-2101 — 50 x 80 x 28mm; 190 g; 200 mA
  • UC-2102 — 50 x 80 x 28mm; 190 g; 330 mA
  • UC-2104 — 57 x 80 x 30.8mm; 220 g; 800 mA
  • UC-2111 — 77 x 111 x 25.5mm; 290 g; 350 mA
  • UC-2112 — 77 x 111 x 25.5mm; 290 g; 450 mA

All five UC-2100 variants default to a -10 to 60°C operating range except for the UC-2104, which moves up to -10 to 70°C. In addition, they are all available in optional -40 to 75°C versions.

Other ruggedization features are the same, including anti-vibration protection per IEC 60068-2-64 and anti-shock per IEC 60068-2-2. A variety of safety, EMC, EMI, EMS, and hazardous environment standards are also listed.

The first three models ship with 256MB DDR3, while the UC-2111 and UC-2112 offer 512MB. These two are also the only ones to offer micro-SD slots. All five systems ship with 8GB eMMC loaded with the MIL distribution.

The UC-2100 systems vary in the number and type of their auto-sensing, 1.5 kV isolated Ethernet ports. The UC-2101 and UC-2104 each have a single 10/100Mbps port, while the UC-2102 and UC-2111 have two. The UC-2112 has one 10/100 and one 10/100/1000 port. The UC-2104 is the only model with a mini-PCIe socket for 4G or WiFi.

The UC-2111 and UC-2112 offer 2x RS-232/422/48 ports while the UC-2101 has one. It would appear that the UC-2102 and UC-2104 lack serial ports altogether except for the RS-232 console port available on all five systems.

The UC-2100 provides push buttons and dip switches, an RTC, a watchdog, and LEDs, the number of which depend on the model. A wall kit is standard, and DIN-rail mounting is optional. TPM 2.0 is also optional. A 5-year hardware warranty is standard.

Further information

The UC-2100 Series gateways appear to be available for order, with pricing undisclosed. More information may be found on Moxa’s UC-2100 product page. More information about the UC-2100, as well as the related, upcoming UC-3100 and UC-5100 Series, will be on tap at Hannover Messe 2018, April 23-27, at the Arm Booth at Hall 6, Booth A46.

LTE Cat M1, NB-IoT Module Provides 2G Fallback

U‑blox has announced the SARA‑R412M, an LTE Cat M1, NB‑IoT, and quad‑band 2G (EGPRS) module with worldwide coverage. Measuring just 16 x 26 mm, the module is the world’s smallest to provide both LTE and quad‑band EGPRS support in a single design. The flexibility extends further with dynamic system selection as Cat M1, NB‑IoT, and EGPRS in single mode or as a preferred connection that does not require a module reboot to switch between modes. It brings a rich feature suite optimized for LPWA (low‑power wide‑area) IoT applications that require the assurance of 2G connectivity to guarantee broad geographic coverage, even in areas where LTE Cat M1 and NB‑IoT are not widely available yet. New IoT devices deployed in the field today can activate on existing 2G networks and still leverage the benefits of LTE Cat M1 and NB‑IoT technology once it becomes available.

The SARA‑R4 series covers a whole host of IoT applications, especially those reliant on long‑term, low power use or requiring connectivity deep within buildings. Examples include gas, water, and electricity metering, city street lighting, building automation, HVAC (heating, ventilation, and air conditioning), industrial monitoring and control, telematics, insurance, asset and vehicle tracking, security systems, alarm panels, outpatient monitoring, and many consumer wearables.

SARA‑R412M enables global solutions based on a single hardware version, allowing developers to select their own desired frequencies and operator configurations. SARA‑R412M ensures data integrity between applications via secure communication protocols, notably including two‑way authentication between client and server, a strategy often used with cloud services.

Critical firmware updates can be delivered with the u‑blox proprietary uFOTA (firmware over the air) client/server solution that uses LWM2M, a light and compact protocol that is ideal for IoT applications. This allows end‑users to continue using the same hardware when features and functionalities are updated, making it well‑suited for critical applications running on devices that may be deployed in the field over long periods of time.

SARA‑R412M provides an extended temperature range of -40 to +85°C, and supports Power Save Mode (PSM) and Extended Discontinuous Reception (e‑DRX) for LTE Cat M1 and NB‑IoT connectivity, which can extend battery lifetime for up to 10 years.

3GPP Coverage Enhancement allows the module’s Cat M1 connectivity to reach deeper into buildings and basements, and even underground with NB‑IoT when compared to other air interface technologies such as GSM or Cat 1.

Technology and Test Solutions for 5G

Next-Gen Communications

As carriers worldwide prepare for 5G communications, chip suppliers and test equipment vendors are evolving their products to meet the challenges of the 5G era.

By Jeff Child, Editor-in-Chief

The technologies that are enabling 5G communications are creating new challenges for embedded system developers. Faster mobile broadband data rates, massive amounts of machine-to-machine network interfacing and daunting low latency constraints all add to the complexity of 5G system design. Feeding those needs, chip vendors over the past 12 months have been releasing building blocks like modem chips and wideband mixers supporting 5G. And test equipment vendors are keeping pace with test gear designed to work with 5G technology.

With standards expected to reach finalization around 2020, 5G isn’t here yet, But efforts worldwide are laying the groundwork to deploy it. For its part, the Global mobile Suppliers Association (GSA) released a report in October 2017 entitled “Evolution from LTE to 5G.” According to the report, there is a frenzy of testing of 5G technology and concepts worldwide. The GSA has identified 103 operators in 49 countries that are investing in 5G technology in the form of demos, lab trials or field tests that are either under way or planned. Operators are sharing their intentions in terms of launch timetables for 5G, or prestandards 5G. The earliest launch dates currently planned are by operators in Italy and the US. Those early launches are necessarily limited in scope to either specific applications, or in limited geographic areas where they will function as extended commercial trials. Figure 1 shows the countries and the current planned dates for the earliest 5G launches in those countries.

FIGURE 1
Here is a map of pre-standards and standards-based 5G network plans announced. It shows the countries and current planned dates for the earliest 5G launches in those countries. (Source: Global mobile Suppliers Association (GSA)).

THE BIG PLAYERS

Intel and Qualcomm have been the big players to watch for 5G enabling technologies. In October 2017, Qualcomm Technologies, a subsidiary of Qualcomm, hit a significant milestone successfully achieving a 5G data connection on a 5G modem chipset for mobile devices. The Qualcomm Snapdragon X50 5G modem chipset achieved speeds and a data connection in the 28 GHz mmWave radio frequency band. The solution is expected to accelerate the delivery of 5G new radio (5G NR) enabled mobile devices to consumers. Along with the chip set demo Qualcomm Technologies previewed its first 5G smartphone reference design for the testing and optimization of 5G technology within the power and form-factor constraints of a smartphone.

The 5G data connection demonstration showed the chip set achieving Gigabit/s download speeds, using several 100 MHz 5G carriers and demonstrated a data connection in the 28 GHz millimeter wave (mmWave) spectrum. In addition to the Snapdragon X50 5G modem chipset, the demonstration also used the SDR051 mmWave RF transceiver IC. The demonstration made use of Keysight Technologies’ new 5G Protocol R&D Toolset and UXM 5G Wireless Test Platform. Qualcomm Technologies was the first company to announce a 5G modem chipset in 2016. The Snapdragon X50 5G NR modem family is expected to support commercial launches of 5G smartphones and networks in the first half of 2019. …

Commercial Drone Design Solutions Take Flight

Chips, Boards and Platforms

The control, camera and communications electronics inside today’s commercial drones have to pack in an ambitious amount of functionality while keeping size, weight and power as low as possible.

By Jeff Child, Editor-in-Chief

There aren’t many areas of embedded systems these days that are as dynamic and fast-growing as commercial drones. Drones represent a vivid example of a technology that wouldn’t have been possible if not for the ever-increasing levels of chip integration driven by Moore’s law. Drones are riding that wave, enabling an amazing rate of change so that 4k HD video capture, image stabilization, new levels of autonomy and even highly integrated supercomputing is now possible on drones.

 

The Intel Aero Ready to Fly Drone is a pre-assembled quadcopter built for professional drone application developers. The platform features a board running an Intel 2.56 GHz quad-core Intel Atom x7-Z8750 processor.

To get a sense of the rapid growth of drone use, just consider drones from the point of view of the Federal Aviation Administration (FAA). Integrating commercial drones into the FAA’s mission has been a huge effort over the past couple years. To paraphrase Michael P. Huerta, Administrator of the FAA, there are over 320,000 registered manned aircraft today and it took 100 years to reach that number. In contrast, only nine months after the FAA put its drone registration process in place, there were more than 550,000 registered users—comprised of both hobbyists and commercial drone users.

Electronics for Drones

Today’s commercial/civilian drone technologies are advancing faster than most people could have imagined only a couple years ago. And drone designs will continue to reap the benefits of advances in processor / chip technologies, sensor innovations and tools that make them easier to create. Feeding those needs, chip and board vendors of all sizes have been rolling out solutions to help drone system developers create new drone products and get to market quickly. Among these vendors are large players like Intel and Qualcomm–along with a whole host of specialized technology suppliers offering video ICs, single-chip cameras and a variety of sensor solutions all aimed at drone platforms. ….

U-blox Modules Demo on T-Mobile’s NB-IoT Network

U‑blox featured a live Narrowband IoT (NB‑IoT or LTE Cat NB1) demo at MWC Americas in San Francisco, featuring SARA‑R410M‑02B, a configurable LTE Cat M1/NB1 multi‑mode module with worldwide coverage. NB‑IoT is a highly efficient type of spectrum and the globally preferred standard due to benefits like cost savings, extended battery life SARA-R410Mand the ability to support a large number of connected devices.

U‑blox has partnered with Bluvision, a provider of highly scalable end‑to‑end IoT platforms, to display Cold Chain Temperature Monitoring and Condition Monitoring using Bluvision’s BluCell. BluCell, a narrowband gateway that uses Bluetooth to wirelessly monitor hundreds of beacons, each measuring temperature, vibration analysis, door openings, location and movement. BluCell is connected via the U‑blox SARA‑R410M‑02B to T‑Mobile’s network, expected to be the first NB‑IoT network in North America. The module is expected to be certified and available in early 2018 for T‑Mobile’s NB‑IoT network, which is expected to launch nationwide in mid‑2018.

For the demo, Bluvision’s BEEKs beacons with sensors for temperature, vibration, magnetic fields and ambient light were attached to a cooler. The beacons transmited telemetry data, which includes real‑time and historical temperature log for the cooler and the vibration data from the compressor motor in the cooler, to the Bluzone cloud solution.

SARA‑R410M is a configurable LTE Cat M1/NB1 multi‑mode module with worldwide coverage. Measuring just 16 x 26 mm, it offers both LTE Cat M1 and Cat NB1 in a single hardware package, as well as software‑based configurability for all deployed global bands. It provides enormous efficiencies in logistics and SKU management. Customers can easily respond to changes in business or market conditions, since supported frequencies and operator configuration decisions can now be made at “zero hour” or even later in the field.
