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.

Expert Series: The Advantages of Chirp Technology

Posted by Olivier Seller on Mar 16, 2020 12:00:00 AM

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
