RF power monitoring tools on the cheap

Recently we at @ttncat had to prepare a crash course on LoRa, LoRaWAN and The Things Network for a professional school in Barcelona. It was a 15 hours course that covered from the very basics to some more advanced topics on RF like link budget, attenuation or impedance matching. It was fun to go back to my years at college and revisit and update some of those topics. And at the same time it was a great opportunity to upgrade my toolbox....

Monitor your TTN gateways with Node-RED

This time I’d like to write a quick post about a small project we’ve been working on at the The Things Network community in Barcelona (@ttncat). We were worried about the monitoring of the gateways we have deployed, both as a community but also as individuals. Some of our partners have also deployed their own gateways and they are part of the community.

Often the families in that situation can’t afford an internet connection at home so WiFi is out of question. GPRS would be an option but lately other radio technologies have come to my interest....
