LoRaWAN From Space
summary
A cubesat LoRaWAN gateway built from commercial RF front ends, an FPGA and an MCU modem is presented, with hardware and field tests including high-altitude balloon flights and a live downlink demo. The project demonstrates working uplinks to small satellites and integration so devices appear through normal LoRaWAN provisioning and roaming, while documenting practical issues such as ~7.5 km/s orbital motion, short passes, and Doppler shifts/frequency deviations up to about 20 kHz.
