UPDATED!  All You Need to Know About LoRa Edge™

Posted by Sree Durbha on Mar 14, 2022 8:00:17 AM

As you probably know, LoRa Edge™ is an ultra-low power platform that integrates a long range LoRa® transceiver, multi-constellation scanner, and passive Wi-Fi AP MAC address scanner targeting GNSS asset management applications. Additionally, the LoRa Edge LR1110 solution uses Semtech’s LoRa Cloud™ geolocation capabilities to significantly reduce power consumption by determining asset location in a Cloud-based solver.

UPDATED: Recent Developments in Long Range IoT

Posted by Roelof Koopmans on Sep 1, 2021 12:08:37 PM

LoRaWAN® has become a leading wireless protocol for many Internet of Things (IoT) applications that require long range wireless connectivity in combination with ultra-low power consumption. Many massive IoT applications are only economically viable when the batteries in the sensors, trackers or other devices can last years , in some cases even more than 10 years.

Certifying an End Device for LoRaWAN®: European Sub-Bands

Posted by Tim Cooper on Jul 19, 2021 12:00:00 AM

The European radio regulations can be ambiguous when it comes to certifying and understanding LoRaWAN® network operation. Here we take a look at how an end device built with a LoRa® chipset should be certified for regulatory compliance, as well as the duty-cycle capacity we can expect from an end device deployed in a practical LoRaWAN network.

Learn all about LoRa and LoRaWAN in French

Posted by Katy Koenen on Mar 4, 2021 1:12:05 PM

Sylvain Montagny, Associate Professor at Savoie Mont Blanc University, is passionate about the Internet of Things. So passionate, in fact, that he teaches a course at the university where students learn to create their own Internet of Things (IoT) solutions using Semtech’s LoRa® devices and the LoRaWAN® protocol.

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.

Expert Series: Testing Devices Featuring LoRa® [How To]

Posted by Sebastien Lebreton on Nov 9, 2020 12:00:00 AM

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.

UPDATED—New Official Communication Profile For Running DLMS Standard Over LoRaWAN®

Posted by Rémi Demerlé on Oct 12, 2020 12:00:00 AM

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.

Understanding the LoRaWAN® Architecture

Posted by Katy Koenen on Sep 9, 2019 2:28:26 AM

 

LoRaWAN® networks primarily use the Aloha method for communication between end devices and their associated network servers. Using the Aloha method, end devices send data through a gateway to the network server only when one or more of their sensors notice a particular change in their environment or when some other event is triggered, such as a timer expiring. After the end device sends the uplink, it “listens” for a message from the network one and two seconds after the uplink before going back to sleep.
