Semtech has announced that machineQ, Comcast’s enterprise Internet of Things (IoT) network service, has connected operational LoRaWAN networks to 10 U.S. cities. The extensive and comprehensive network coverage in these markets increases access at the network edge to add value to solutions providers and enterprises, establishing a strong foundation for nationwide deployment.
According to ABI Research, IoT technology revenues across 12 key smart city technologies and verticals, including metering, parking and street lighting, is expected to grow from around $25 billion in 2017 to $62 billion in 2026 at an average growth rate of 11%. This rapid adoption will need a proven infrastructure that is able to scale and provide key LoRa capabilities to support multiple applications. MachineQ has rolled out networks in Philadelphia, Chicago, San Francisco, Atlanta, Baltimore, Boston, Denver, Detroit, Indianapolis, Miami, Minneapolis/St. Paul, Oakland, Pittsburgh, Seattle and Washington D.C. The comprehensive network presence in these 10 cities demonstrates the steady progress of enabling smart business decisions with the broad adoption of Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology) for their smart applications.

MachineQ’s widespread and comprehensive presence in these 10 cities demonstrates shows that Semtech’s LoRa Technology is able to support a diverse number of applications in making cities smarter, from improving parking congestion to remote lighting control for street lights.
STMicroelectronics has announced the availability to all–including students, makers, and budding engineers and computer scientists–of the online “Introduction to Embedded Systems with SensorTile” course. With a curriculum developed by Professor William Kaiser at the University of California, Los Angeles (UCLA), and used to teach his freshman engineering class, the online course resources provide a foundation to understand the fundamentals of a sensor-based Internet of Things (IoT)-enabled embedded system. Professors at other universities are also encouraged to adapt and contribute to the course.
The introductory course of 8 self-paced tutorials is designed around ST’s SensorTile, a unique real-time IoT-enabled embedded system on a postage-stamp-sized module. The tiny 13.5 mm x 13.5 mm module combines a high-performance, low-power STM32 Arm-Cortex-M-core microcontroller, 5 valuable MEMS (Micro-Electro-Mechanical Systems) sensors—an inertial sensor containing an accelerometer and gyroscope, an eCompass, a pressure sensor, and a microphone—and a Bluetooth network processor. A kit with the module, cables, cradle and a battery is available from major resellers for about $80.
The joint effort with ST makes the 8 tutorials freely available online, with a full complement of documentation, open-source algorithms and development solutions, and unfettered access to a growing user forum. Anyone interested in learning more about the tutorial or purchasing a SensorTile kit should visit the web site www.st.com/sensortile-edu). Additional information is available, as well, on the ST blog: blog.st.com/introduction-embedded-systems-sensortile-online-course/
Semtech has announced its next generation LoRa devices and wireless radio frequency (RF) technology (LoRa Technology) chipsets enabling innovative LPWAN use cases for consumers with its advanced technology. Addressing the need for cost-effective and reliable sensor-to-cloud connectivity in any type of RF environment, the new features and capabilities will significantly improve the performance and capability of IoT sensor applications that demand ultra-low power, small form factor and long range wireless connectivity with a shortened product development cycle.
The next generation LoRa radios extends Semtech’s industry leading link budget by 20% with a 50% reduction in receiver current (4.5 mA) and a high power +22 dBm option. This extends battery life of LoRa-based sensors up to 30%, which reduces the frequency of battery replacement. The extended connectivity range, with the ability to reach deep indoor and outdoor sensor locations, will create new markets as different types of verticals integrate LoRa Technology in their IoT applications including healthcare and pharmaceuticals, media and advertising, logistics/shipping and asset tracking.
The new platform has a command interface that simplifies radio configuration and shortens the development cycle, needing only 10 lines of code to transmit or receive a packet, which will allow users to focus on applications. The small footprint, 45% less than the current generation, is highly configurable to meet different application requirements utilizing the global LoRaWAN open standard. The chipsets also supports FSK modulation to allow compatibility with legacy protocols that are migrating to the LoRaWAN open protocol for all the performance benefits LoRa Technology provides.
Three new devices, SX1262 (+22dBm), SX1261 (+15dBm) and SX1268 (+22dBm, China frequency bands) are currently sampling to lead customers and partners and will be available in full production in late Q1 2018. Development kits for various regions and associated software will also be available at that time.

LoRAWAN is a Low Power Wide Area Network (LPWAN) based on LoRa technology that is opening up a world of possibilities to create networks of connected devices ideal to address a broad range of IoT applications. The benefits of LoRa especially suit applications where nodes have limited power capability, can be difficult to access, and data transfers don’t require high bandwidth. LoRa can target a wide spectrum of applications such as tracking, proactive maintenance, and many others. Industry analysts estimate there will be tens of billions of connected devices deployed in the world by 2020.
Objenious launched and operates the first LoRa network in France, with more than 4,200 antennas deployed around the country. Leveraging the network know-how inherited from Bouygues Telecom, Objenious now proposes its LoRa network, platform, and services for LPWAN IoT to partners and customers locally and internationally thanks to roaming agreements.
STMicro helps developers by providing tools and software libraries that aid the STM32 MCU-based embedded design as part of its freely available STM32 Open Development Environment (ODE). By integrating Objenious’ network access software on top of the STM32 ODE, developing connected devices is even easier. STM32 Nucleo LoRa kits are now certified and available to developers through ST sales channels.

Semtech has announced its collaboration with National Narrowband Network Communications (NNNCo) to build a nationwide rural IoT network to bring high-tech agriculture solutions to Australian farmers. The LoRaWAN open standard developed by the LoRa Alliance is expected to help transform Australia’s farms, giving farmers real-time data on soil moisture, rainfall, crops, water levels, and livestock through a network of in situ low-cost wireless sensors. One of the key comptabilities of a LoRaWAN is that it enables users to communicate bi-directionally with sensors on an individual or group level.
The sensors use limited power and can operate ‘in the field’ for years without the need for intervention. The farmer will be able to make intelligent, sound decisions to drive multiple functions, including irrigation, livestock feed stations, water pumps, and emergency signals. The LoRaWAN network will immediately cover one million acres of farmland across rural New South Wales (NSW) which will encompass dry land crops, horticulture and livestock and a number of rural towns. Within 18 months, the plan is to extend broadly across Australia.
Semtech’s LoRa wireless RF technology is a widely adopted long-range, low-power solution for IoT that gives telecom companies, IoT application makers and system integrators the feature set necessary to deploy low-cost, interoperable IoT networks, gateways, sensors, module products, and IoT services worldwide. IoT networks based on the LoRaWAN specification have been deployed in over 50 countries.
