1. A wireless power transmission system comprising:
a first transmission antenna configured to couple with a first receiver antenna and transmit virtual alternating current (AC) power signals to the first receiver antenna, the virtual AC power signals generated based on a first driving signal;
a second transmission antenna configured to couple with a second receiver antenna and transmit virtual direct current (DC) power signals to the second receiver antenna, the virtual DC power signals generated based on a second driving signal;
a controller including at least one processor;
at least one non-transitory machine-readable medium; and
program instructions stored on the at least one non-transitory machine-readable medium that are executable by the at least one processor such that the at least one processor is configured to:
determine the second driving signal for driving the second transmission antenna based on a second operating frequency before transmission of the virtual AC power signals by the first transmission antenna;
determine initiation of transmission of the virtual AC power signals by the first transmission antenna by decoding in-band data signals from the second receiver antenna via the second driving signal;
determine the first driving signal based on a first operating frequency, a virtual AC power frequency, a slot length, and a slot timing;
determine the second driving signal for driving the second transmission antenna based on the second operating frequency, the slot length, and the slot timing for after the initiation of transmission of the virtual AC power signals by the first transmission antenna;
drive the first transmission antenna based on the first driving signal and the slot timing to transmit the virtual AC power signals; and
drive the second transmission antenna based on the second driving signal and the slot timing when the transmission of the virtual AC power signals by the first transmission antenna are halted.
