Experimenting with wireless protocols requires expensive equipment and specialized knowledge. Many developers just need occasional RF analysis.
Provide API access to remote SDR hardware with pre-configured decoders for common protocols like LoRa, Zigbee, and custom signals.
Charge by the hour for hardware access or per decoded packet.
MVP could be a Raspberry Pi cluster with basic SDR dongles.
Risk: May run afoul of radio transmission regulations in some regions.
