Developing LoRaWAN-based Devices:
Things to Know
Here you’ll find technical recommendations for developers of LoRaWAN devices. These best practices cover everything from provisioning and testing devices to managing them.
The Immune System | Avoiding RF Interference with LoRa
In this article, Tim Cooper tackles the problem of hard-to-predict power levels and unforeseen interference sources in the license-free ISM band, and shows you how to answer the deceptively simple question:
How likely is my radio to be immune to the interference it will encounter?
Understanding the LoRa® Adaptive Data Rate
Using Adaptive Data Rate (ADR), you can easily scale a LoRaWAN network, simply by adding gateways, thus drastically increasing its capacity. This technical paper explains what the ADR mechanism is and how it works.
LoRaWAN® Mobile Applications: An Introduction to Blind ADR
The LoRaWAN® adaptive data rate (ADR) mechanism slowly adapts the data rate between an end device (“end node”) and a gateway depending upon the prevailing channel conditions. However, when it comes to mobile applications, we run into conflicting requirements when it comes to power consumption, link budget, and airtime. Blind ADR helps mitigate these conflicts.
“Class A” Devices: What You Need to Know
LoRa®-based device can operate in three different modes, Class A, Class B, and Class C. In this paper we highlight the main differences between these three modes, and go into depth about how devices in Class A mode work.
“Class B” Devices: What You Need to Know
In this paper, we continue our discussion about the differences between the operating modes of LoRa-based devices, and dive deep into what it means for a device to operate in Class B mode.
“Class C” Devices: What You Need to Know
Here, we wrap up our discussion of the three modes in which a LoRa-based device can operate, and explain in more depth what sets Class C devices apart from the others.
LoRa® and LoRaWAN®: A Technical Overview
This article provides an introduction to the LoRa® and LoRaWAN® technologies. Here, we discuss key LoRa modulation properties and characteristics and explain the fundamentals of a LoRaWAN network.This article provides an introduction to the LoRa® and LoRaWAN® technologies.

Locating End Devices with Semtech’s LoRa Cloud™ Geolocation Service
Technology allowing you to locate wireless sensors is of key importance in realizing their full value. While the Global Positioning System (GPS) is probably the most widely known technology, it may not always be the best choice for locating such sensors. In this paper, we explore the merits of using LoRaWAN®-based networks to locate end devices.
Picocell Gateway User Guide
The LoRa PicoCell Gateway V1.0 is a multi-channel high performance transceiver designed to simultaneously receive several LoRa packets using random spreading factors.
From LoRaMAC-Node™ to TTN & myDevices User Guide V1.0
This user guide is a step by step guide describing how to use a LoRaMAC-Node stack to send a payload to The Things Networks (TTN), then to myDevices / Cayenne in Low Power Payload (LPP) format.
Smart Building Reference Kit User Guide
The Smart Building Reference Kit (“Kit”) is designed to provide validation of the network coverage within a building, accelerate solution development and facilitate a portable demonstration to a wide range of stakeholders. By moving the location of the sensors to different spots around the building, users can determine a gateway’s range of coverage.
The LoRaMote is a demo platform intended to showcase the capability of the SX1272 and especially the LoRa modulation. The platform is fitted with various sensors which provide a variety of applications.
