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.

Shape the Future of the LoRa® Developer Portal

Posted by Katy Koenen on Jul 27, 2020 10:46:16 AM

We launched the LoRa® Developer Portal a little more than a year ago. Our goal was to provide a central hub for developers and solution providers in the LoRa ecosystem; a place to find education and training materials, best practices, user guides, and more. To this end, we have been providing the following resources:

Making the Most of the Unlicensed Spectrum

Posted by Frank Gielissen and Maarten Weyn (Aloxy) on Jun 22, 2020 12:00:00 AM

Low Power, Wide Area Networks (LPWANs) are key to the success of Internet of Things (IoT) deployments that need to cover a broad geographical area. LoRaWAN® is an open protocol for one type of LPWAN, while DASH7 is another. Both use the unlicensed spectrum and together they offer complementary benefits.

Expert Series: 5 Things You Need to Know about LoRaWAN®-based Gateways

Posted by Anton Beitler, Alexandru Caracas, and Richard Fuller on Jun 1, 2020 12:00:00 AM

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.

On-boarding Devices to the Helium Network

Posted by Kent Williams on May 18, 2020 12:00:00 AM

On-boarding Devices Securely

There are many diverse applications for LoRaWAN® devices. Similarly, there is a wide and diverse population of end users. These factors lead to a device on-boarding process that takes just as many forms. Device on-boarding is the process of associating a device with a particular network and application server. It is the foundation of a device's level of security. It precedes and enables device activation, whether over-the-air activation (OTAA) or through activation by personalization (ABP), which themselves become compromised if the device on-boarding is done incorrectly.

Provisioning Devices for Maximum Compatibility

Posted by Sebastien Lebreton on May 11, 2020 12:00:00 AM

To ensure that a LoRaWAN®-based device can be uniquely and securely identified on a network, it needs a unique ID and other security key material. Using a device’s unique, built-in identifier and deriving the appropriate key material is called provisioning the device. In this article, we’ll take a look at the best practices for provisioning your devices.
