I wonder what the frequency of operation is -- 315, 433 or 869 MHz?

Shawn from Beep here. We use the 902-928MHz band in the US.

915 MHz in the US.

EDIT: Actually I suppose since it isn't LoRaWAN, it could be 433 MHz.

433MHz isn't unlicensed spectrum in the US, its in an amateur radio band. Wouldn't be legal for commercial use like this.

868 MHz band in Europe
