1. A device, comprising:
one or more antennas configured to receive a radio frequency (RF) emission wirelessly from a source device;
a power splitting circuitry configured to:
split the RF emission into a first part and a second part of the RF emission based on a threshold; and
transmit the first part of the RF emission to an energy harvesting circuitry while transmitting the second part of the RF emission to a wireless transceiver;
the energy harvesting circuitry configured to charge the device using the first part of the RF emission;
the wireless transceiver configured to receive the second part of the RF emission; and
at least one processor communicatively coupled to the wireless transceiver and configured to:
determine that an energy level of an energy storage unit of the device is above the threshold; and
in response to determining that the energy level is above the threshold, transmit, using the wireless transceiver, the second part of the RF emission wirelessly to a second device to charge the second device.
