Understanding the LoRaWAN® Architecture

Posted by Katy Koenen on Sep 9, 2019 2:28:26 AM


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.

Farming to Food Safety: How LoRa®-based Technologies are Changing Agriculture

Posted by Katy Koenen on Aug 21, 2019 6:24:19 AM

This week we’re exploring some of the ways that LoRa-based devices and LoRaWAN® networks are at work in the food chain.

The Internet of Things (IoT) is constantly expanding its reach. We’re getting accustomed to the notion of smart buildings and smart cities, but smart agriculture may not be top of mind when we think of the IoT. Nevertheless, farmers are quickly adopting IoT and LPWAN technologies – particularly solutions based on the LoRaWAN protocol – to great effect.

Announcing availability of workshop videos for LoRa Basics™ MAC and LoRa Basics™ Station

Posted by Katy Koenen on Aug 20, 2019 9:14:17 AM

LoRa Basics™ MAC and LoRa Basics™ Station are tools designed for developers creating LoRaWAN®-based solutions. LoRa Basics MAC is a portable implementation of the LoRa Alliance® LoRaWAN specification in the C programming language. LoRa Basics MAC supports multiple regions, selectable at compile and/or run-time, and supports Class A, Class B and Class C devices. LoRa Basics Station is an implementation of a LoRa® packet forwarder, which can be remotely managed by a Configuration and Update Server (CUPS) at regular intervals to obtain configuration, system and firmware updates.

Be a Part of the Developer Showcase

Posted by Steven Hegenderfer on Aug 5, 2019 6:30:00 AM

The Semtech Developer Ecosystem team is always looking for new ways to help enrich the developer community. It is with this in mind that we are getting ready to launch a new facet of our LoRa® Developer Portal, the Developer Showcase.

The Developer Showcase will be an area where developers can submit tips, tricks and best practices on how to solve LoRaWAN® application and deployment issues. We will back this launch with a marketing campaign, and share these ideas with the world.

After almost two years, the world record for distance traveled by a data packet based on the LoRaWAN® protocol – 702 kilometers (436 miles) – has been broken. Set in 2017, this record was regarded by many as nearly impossible to break; that is, until the recent Servet IV mission. On July 13, 2019, the previous record was exceeded by 64 kilometers for an astonishing distance of 766 kilometers (476 miles).

On Saturday, July 13, 2019, seven balloons of different sizes launched from Alfamen in Zaragoza, Spain. The balloons carried 20 experiments from developers, ranging from young talents to veteran makers. The balloons were tracked using The Things Network, LoRaWAN-based networking infrastructure by APRS and by satellite using Spot.

LoRaWAN® and NB-IoT Working to Connect the IoT

Posted by Steven Hegenderfer on Jul 18, 2019 1:28:46 AM

The Internet of Things (IoT) is all about connecting devices together to let users, and each other, know what’s going on.

What is my temperature? Where am I? What is the gas level? How are the acoustics near me? What level of vibration am I experiencing? And on and on and on.

While the range of devices that need to communicate their status varies greatly, there can be some commonalities. These devices are often in an area where connecting to mains-supplied power is not an option, so they will probably be either battery-powered or use scavenged energy to power themselves.

Don’t misunderstand me, there are use cases for things like self-driving cars and telemedicine that require much more detailed conversations between devices and exchange much more data, but for the majority of IoT devices, they really don’t send a lot of data at any one time. They just need to ‘phone home’ occasionally to report their status or an event.

LoRa Alliance® Device Certification

Posted by Malcolm Green on Jul 12, 2019 1:51:36 AM

The LoRa Alliance® has a certification program to test whether or not an end-device meets the functional requirements of the LoRaWAN® specification. LoRaWAN CertifiedCM end devices ensure interoperability and compliance with any LoRaWAN-based network, and device manufacturers may carry the LoRaWAN Certified mark. The certification mark provides end users with the confidence of using devices that are reliable and that behave according to LoRa Alliance specifications.
