n-Fuse introduces SX1303 mPCIe LoRaWAN concentrator card

I first noticed Semtech SX1303 LoRa baseband processor for gateways was in RAKwireless WisGate Developer Base equipped with RAK5146 SX1303 mPCIe LoRaWAN concentrator card. But n-Fuse now offers another option with their LRWCC3-MPCIE mini PCIe card that is an update to their earlier SX1302 based n-Fuse LRWCC2-MPCIE card announced last year. n-Fuse LRWCC3-MPCIE specifications are very similar with the differences highlighted in bold: MCU – STMicro STM32 LoRa Connectivity Semtech SX1303 digital baseband processor with 2xSX1250 and 1xSX1261 Tx/Rx front-ends Frequency Range – 863 to 870 MHz or 915 to 928 MHz Sensitivity 868 Mhz <= -125dBm at SF7, BW 125KHz <= -140dBm at SF12, BW 125kHz 915 Mhz <= -125dBm at SF7, BW 125KHz <= -140dBm at SF12, BW 125kHz Max RF Output Power – Up to +27dBm Listen Before Talk prevents collisions while accessing the spectrum.

Check LoRaWAN deployments on the go with WisGate Developer Base USB dongle

RAKWireless just had their “Big Tech Bloom” event services they announced many new LPWAN products ranging from WisDM fleet management system, OpenWrt based Wisgate OS, new industrial LoRaWAN gateways like WisGate Edge Lite 2, their first STM32WL module, as well as 9 new modules for WisBlock modular IoT platform with MIC, e-Paper display, GPS, an ESP32 based WisBlock core, etc… But today, I’ll have a look at the new $99 WisGate Developer Base, a USB dongle that connects to a laptop for LoRaWAN networks evaluation, for example, to check the coverage before installing a new gateway. Alternatively, it could also be used to add LoRaWAN gateway capability to existing embedded hardware like routers or industrial PCs. Two variants of the WisGate Developer Base are available – RAK7271 & RAK7371 – with the following specifications: Concentrator modules RAK7271 – RAK2287 SX1302 based mini PCIe concentrator module RAK7371 – RAK5146 SX1303 based […]

LoRaWAN BACnet gateway uses Raspberry Pi CM3+ for building automation

Raspberry Pi BACNet Gateway with LoRaWAN

A few years about we wrote about BASpi I/O Raspberry Pi HAT compatible with BACNet, a data communication protocol for Building Automation and Control Networks, also known as the ISO 16484-6 standard, and used for HVACs, lightings, elevators, fire safety, and other systems found in buildings. But if you’d like a turnkey BACnet solution based on Raspberry Pi, UK-based Innovelec‘s DINGO LoRaWAN BACnet Advanced Gateway/Server may be easier to integrate into your building’s electrical installation and also offers low-power long-range LoRaWAN communication.
