LoRa® Developer Portal: Crossword Corner for October 2019

Posted by Katy Koenen on Oct 7, 2019 9:15:15 AM

Welcome to the October 2019 edition of our Crossword Corner.

Last month we focused on one of Semtech’s new tools: LoRa Basics™ MAC. This month we want to turn your attention to another: LoRa Basics™ Station.

LoRa Basics Station is a LoRa® packet forwarder, that is, a program that runs on the host of a LoRa-based gateway (with or without GPS), forwarding RF packets received by the concentrator (uplinks) to a LoRaWAN® Network Server (LNS) through a secured IP link. It also transmits RF packets sent by the LNS (downlinks) through the same secured IP to some device. Furthermore, it may transmit (potentially network-wide) GPS-synchronous beacon signals used for time coordinating devices within the network.

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.
