Frequently Asked Questions
When we talk about the accuracy of the ranging it is important to draw a distinction between the different kinds of measurements of accuracy and to distinguish between accuracy and precision which are separate technical terms in the context of ranging.
Precision is a measure of the spread of our ranging results, accuracy is a measure of how far the measured distance is from the actual distance, the real distance is referred to as Ground Truth. A full description of these terms is given in our application note on the SX1280 ranging functionality.
With the latest version of the SX1280 development kit ranging firmware (available from the "https://developer.mbed.org/components/SX1280RF1ZHP/" target="_blank">Tools and SW area) we attain +/- 3 m of overall accuracy in line of sight conditions using the standard development kits mounted at 1.8 m and following the ranging guidance outlined in the ranging explanation document. Note that the accuracy seen is not a function of range, but rather the environment and obstructions between the radios. As we can see below, the accuracy is not significantly different at 50 m and at 2005 m.

LoRaCloud.com has all the details about the Device Join service, the GLS and DAS
Unfortunately, no. The LoRa Basics™ Modem-E is a modem based on the LoRaWAN® protocol and is certified to run on LR1110.
There are dedicated landing pages for the LoRa Edge Tracker Reference Design for Europe and North America. From there, you can navigate to the LoRa Developer portal where you can find more technical collateral, including the LoRa Edge Tracker Evaluation Kit Quick Start Guide, the LoRa Edge Tracker Reference Design User Guide, and much more.
Actility and a lot more via the ThingExchange Peering Hub
They will have to make sure they are using a NS that has passed interop testing with the Semtech JS. Subsequently, they should go through interconnection setup (an IT procedure). Semtech JS is already connected to Actiliy's peering hub platform, ThingPark Exchange. Any network that is connected to ThingPark Exchange can be readily interconnected with the Semtech JS. Others will have to go through individual interconnection setup.
We are waiting for LoRa Alliance to ratify the spec for the FUOTA spec. You can rest assured that Semtech will make this feature commercially available as soon as the Alliance is ready to certify our product with it.
API details can be found in the LoRa Edge Tracker Reference Design User Guide
The LoRa Edge Tracker Evaluation Kit sold via Actility’s ThingPark Market includes two tracking devices and an indoor gateway that leverages the LoRaWAN networking protocol. The gateway comes pre-staged for the ThingPark Community Platform, from Actility, which allows you to add the gateways and the trackers on its network server. You can also create an account on TagoIO’s application platform to monitor and manage the trackers.
The Cloud solver is an integral part of the LoRa Edge platform for computing a position fix using GNSS and for acquiring a Wi-Fi based location fix using triangulation of static MAC addresses. Key advantages of using Semtech’s end-to-end LoRa Cloud solution include:
- Simplified means of joining a device to the network with the LoRa Cloud Device Join service
- Easy device management with the LoRa Cloud Device & Application Services
- Firmware Updates Over the Air (FUOTA)
- On-premise support
However, if you want to source, test and assemble these pieces independently, we will support that as well.
