Buy Versus Build: Options for LoRa Cloud™ Geolocation Integrations

Implementing a Semtech LoRa Cloud™ geolocation application may be simpler than you think. Semtech, together with valuable Internet of Things (IoT) ecosystem players, offers the resources to help. In this article we explain both build and buy options to arrive at a full asset tracking application, which incorporates LoRa Cloud, to address your specific use case.

LoRaWAN® E-book from Savoie Mont Blanc University Now Available

An associate professor at the Savoie Mont Blanc University, Sylvain Montagny specializes in microprocessor systems and the Internet of Things (IoT). In his role at the university, he is in charge of the postgraduate master’s program in Electronics and Embedded Systems. Montagny and his colleagues on the teaching staff of Savoie Mont Blanc University have created a course dedicated to LoRa® and LoRaWAN®, based on the curricula of the following courses:

UPDATED! All You Need to Know About the LoRa Edge™ Asset Management Platform

An innovative software and hardware solution designed to enable cost-effective and energy-efficient asset tracking and management solutions, the LoRa Edge™ asset management platform addresses a wide variety of use cases and scenarios, thanks to the versatile and configurable components that make up the system. Furthermore, it uses Semtech’s LoRa Cloud™ geolocation capabilities to significantly reduce power consumption by determining asset locations in a cloud-based solver.

A wealth of information about the LoRa Edge asset management platform is available. Here, we’re packaging it all up in one place to make finding what you need easier.

UPDATED: Recent Developments in Long Range IoT

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.

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.

Enhancing Asset Tracking with the LoRa® SX1303 Fine Timestamp Feature

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]

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.

Expert Series: The Advantages of Chirp Technology

Chirps are great for low power wide area networks (LPWAN) because they occupy a single dimension.

Let’s start with a real-world analogy: it is difficult to get lost in a one-dimensional space. For instance, if you walk along a coastline or a river it is fairly easy to find your way back. Similarly, it is possible to set up an appointment with a friend in a one-dimensional space (in a loose manner) such as “Let’s meet on Main Street near the restaurants.” If you’re both walking along Main Street near the restaurants at roughly same time, you will very likely encounter one another.

The Key Advantage of LoRaWAN®

There are a number of differentiators for LoRa® devices and the LoRaWAN® protocol that have helped in its widespread adoption, including long range connectivity, battery lifetime, security, network architecture, and network capacity. However, there is one particular feature that will drive LoRaWAN adoption for years to come. Technical challenges or limitations (range, capacity, battery lifetime, etc.) are no longer a barrier to Internet of Things (IoT) adoption. The remaining challenges of the IoT are system integration, digital transformation, return-on-investment (ROI), service level agreements (SLA), and ensuring interoperability across an ecosystem.

Understanding the LoRaWAN® Architecture

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.
