1. A wireless transmission system comprising:
an input power supply configured to provide power at a first voltage (V1);
a first wireless power transmission system configured to:
receive first direct current (DC) input power at a first power input from the input power supply, the first DC input power received at a voltage substantially similar to V1;
transmit first wireless power signals based on the first power input; and
receive wireless data signals, wherein the wireless data signals are encoded as variations in power of the first wireless power signals;
a second wireless power transmission system configured to:
receive second DC input power at a second power input from a low voltage drop out, the second DC input power having a second voltage (V2) that is lower than V1;
transmit second wireless power signals; and
the low voltage drop out configured to:
receive the first DC input power from the input power supply; and
generate the second DC input power, wherein the second DC input power is isolated from the variations in power of the first wireless power signals.
