Semtech Corporation has announced the LoRa Core™ portfolio with a new chipset, providing global LoRaWAN network coverage and targeted to several vertical industries including asset tracking, building, home, agriculture, metering, and factory automation.
The LoRa Core portfolio consists of sub-GHz transceiver chips, gateway chips and reference designs including SX126x series, SX127x series and LLCC68 transceiver chips, as well as the SX130x series gateway chips, legacy gateway reference designs and the LoRa® Corecell gateway reference designs. Together, they represent the essential capability of Semtech’s LoRa devices including long range, low power and cost effective LoRaWAN end-to-end communication.
New additions to the LoRa Core portfolio are a gateway baseband processor integrated with LoRa (SX1303) and an associated LoRa Corecell gateway reference design that supports the fine timestamp feature.
“The new LoRa Core gateway IC enables the network-centric geolocation of LoRa devices without requiring the inclusion of GPS hardware at each individual end node. Based on a fine timestamp capability that provides accurate time of arrival information for each demodulated message, the new chipset allows gateways to perform network-centric geolocation based on Time Difference of Arrival (TDOA). This is ideal for several cost-sensitive asset tracking applications,” said Pedro Pachuca, Director of Wireless Products in Semtech’s Wireless and Sensing Products Group.
