An increasingly important aspect of operating a LoRaWAN network in a shared ISM band is avoiding interference from existing devices operating in the same band, and minimizing the interference caused to other users of the spectrum. To help network operators achieve this, Semtech is introducing two new features to the SX1302 LoRa Corecell gateway reference design: Listen-Before-Talk (LBT) and Spectral Scan.
As cities develop, the number of traceable assets continues to grow. Similarly, as physical asset management becomes increasingly difficult, the need for more efficient methods is growing.
Semtech recently launched the new LoRa SX1303 baseband processor. Smaller and more efficient than the SX1301, the SX1303 processor also introduces a new feature: Fine Timestamp. This feature provides an efficient solution that enables network-centric geolocation asset tracking—without the need for a power-hungry and expensive GPS.
Just getting started developing Internet of Things (IoT) solutions with Semtech’s LoRa® ICs? Interested in how to build and deploy a device? We have a great technical paper that will walk you through how to build a device from scratch using off-the-shelf components.
Sebastien Lebreton, Principal Applications Engineer at Semtech, has been building and testing devices featuring LoRa® chips for eight years. An expert in the field, he has been working with wireless technologies since 2001, and has regularly been called upon to teach engineers across the LoRa developer ecosystem how to be successful in this arena.
Over the years, I have explained how to test devices with LoRa® chipsets a dozen times or more during seminars, workshops and in informal meetings with customers. The need to write and publish these recommendations for the benefit of the industry has become more than apparent. So, sit back, enjoy a cup of coffee and read on.
In the How to Use LoRa Basics™ Station technical paper from Semtech, Anton Beitler provides in introduction to LoRa Basics Station including:
DLMS is the suite of standards developed and maintained by the Device Language Message Specification User Association (DLMS UA). The DLMS UA is an international and non-profit organization driving utilities and meter manufacturers to develop and support a common standard for data exchanges when it comes to smart metering. The DLMS suite supports a variety of wired and wireless communication standards, such as Cellular, PLC, Zigbee, WMBus, and Prime-PLC. DLMS has the flexibility to offer an application layer that is independent from the media layer, enabling the use of a single application over any of the supported communication technologies – or even a mix of them. For its part, the DLMS UA is now extending adoption to new markets and applications (such as private EV charging station and monitoring of smart infrastructure for electricity, gas and water) demanding a standardized data model and available application layer to enable more intelligent and interoperable devices.
1. The Role of the Gateway in LoRaWAN
The LoRaWAN-based gateway is the physical layer (PHY) interface for the LoRaWAN network server (LNS). On the one hand, it listens to certain parts of the radio spectrum and decodes LoRa®-modulated signals originating from LoRa-based sensors. On the other hand, the gateway transmits messages from the network down to a sensor as LoRa-modulated signals.
