Bidirectional 868/915 MHz wireless module powered with energy harverster

Marcel Meli, Samuel Blättler, Martin Gysel, Valentin Kunz
In this paper, we present a work that allows bidirectional communications in the 868/915 MHz ISM bands, using the power generated by energy harvesters. Our investigations show that a clear channel assessment, receive of acknowledge and resend of the message are possible within a limited, but reasonable time. The design relies on the use of low power microcontrollers and transceivers, and low energy management techniques.
