Systems and methods for wireless transmission of a modulated audio signal to a receiver using near-field or proximity transmission are presented. In exemplary embodiments of the present invention, such systems and methods can receive a broadcast signal with a first receiver, generate an audio signal therefrom, and then use a modulation device to convert the audio signal into a modulated signal. The modulated signal can be retransmitted wirelessly via a radiating element. The radiating element can, for example, be placed in close proximity to a second receiver, thereby enhancing the wireless link from the modulation device to the second receiver, and allowing the radiating element to operate at a relatively low power. In exemplary embodiments of the present invention, the broadcast signal can be, for example, a satellite radio signal, and the retransmission can occur within a vehicle, the second receiver being, for example, an in-vehicle conventional AM/FM radio system. In exemplary embodiments of the present invention, the radiating element can be remote from the first receiver, and can be co-located or integrated with the modulating device in a remote location. In exemplary embodiments of the present invention, a digital to analog converter can also be collocated, in-line with, or integrated with the modulating device and radiating element in the remote location.
