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.

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.

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. ….
