TinySDR: Low Power SDR Platform for Over the Air Programmable IoT Testbeds
summary
A 3×5 cm low-power SDR board that runs on battery, supports duty cycling and remote firmware updates, and targets real IoT testbeds. Hardware uses an SRAM FPGA and MCU split so MAC sleeps at 30 uW sleep while the FPGA handles real-time PHY; LoRa and BLE implementations use 4% and 11% of FPGA resources and reach LoRa −126 dBm and BLE −94 dBm sensitivities. Over-the-air delivery uses a low-rate background radio and updates an FPGA image in about 150 seconds.
