LoRa Corecell Reference Design for Receiving and Transmitting Data Simultaneously in Full-Duplex Gateway Applications

LoRa Corecell Reference Design

Semtech Corporation has introduced the LoRa Corecell Reference Design for full-duplex gateway applications in the U.S. 902 - 928MHz ISM band. The new gateway solution allows users to expand the network capacity for outdoor and indoor applications such as smart metering, smart building, and smart factory. With the new reference design network owners can increase network capacity while deploying fewer gateways, providing cost savings to end customers.

 

The full-duplex LoRa Corecell Reference Design improves LoRaWAN protocol message response time for applications requiring fast acknowledgment from the gateway. This enables Firmware Update Over-The-Air (FUOTA) while processing uplink traffic and reduces the time and cost of operational management of end devices. With simultaneous data transmission and reception, the device can lengthen the downlink window to enable the gateway to send more data to end devices and remove the latency experienced with half-duplex gateways.
