Abstract
An innovative software-defined backchannel communication scheme is provided for use in ultra-low power devices. The technique enables interconnecting heterogeneous devices through a WiFi backchannel that can be realized with existing infrastructure without any hardware modifications. The backchannel communication scheme can also be extended to other OFDM based communication systems, such as cellular 4G LTE.
