A Full Duplex LoRaWAN® Gateway for the U.S. 915MHz ISM Band

Posted by Steve Lee on Jun 21, 2021 12:00:00 AM

 

The LoRa® Corecell Full-Duplex gateway reference design is a highly integrated indoor and outdoor gateway solution designed specifically for the U.S.s 915MHz ISM band. This full-duplex gateway design makes it possible to expand network capacity for outdoor and indoor applications, such as smart metering, smart offices, smart buildings, and smart factories. Moreover, it increases the capacity of networks with fewer gateways, thus providing cost savings for end customers when compared to cellular charges.

Becoming a Better Listener: The SX1302 Gateway Reference Design

Posted by Devesh Katta & Tim Cooper on Jan 25, 2021 7:57:29 AM

An increasingly important aspect of operating a LoRaWAN network in a shared ISM band is avoiding interference from existing devices operating in the same band, and minimizing the interference caused to other users of the spectrum. To help network operators achieve this, Semtech is introducing two new features to the SX1302 LoRa Corecell gateway reference design: Listen-Before-Talk (LBT) and Spectral Scan.

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.
