WIRELESS FM REPEATER SYSTEM
First Claim
1. A wireless FM repeater system for converting an audio signal from a portable audio source and transmitting it to a vehicle'"'"'s FM tuner having an FM tuner antenna where the FM tuner lacks an input jack for coupling to the portable audio source, said system comprising:
- a transmitter, coupled to the audio source, for using a first frequency carrier signal comprising the audio signal to transmit a first transmitted signal, said transmitter comprising a channel select that permits a user to provide said transmitter with an FM frequency channel setting to which the vehicle'"'"'s FM tuner is tuned; and
a self-powered repeater that receives said first transmitted signal and downconverts said first transmitted signal, without demodulating said first transmitted signal, to an FM frequency band carrier signal, said repeater transmitting said FM frequency band carrier signal to form a second transmitted signal, said second transmitted signal being transmitted from a repeater antenna and received by the vehicle'"'"'s FM tuner antenna.

Abstract
A wireless FM repeater system for converting the audio signal from a portable audio source (e.g., iPod, MP3 player, a cell phone or satellite radio, etc.) and transmitting it to the FM tuner of a vehicle stereo system where access to a hard-wired input jack does not exist. The system includes a transmitter, coupled to the audio source, that transmits the audio source signals at a high frequency (e.g., 902-928 MHz, 2.4-2.483 GHz, 434/868 MHz) to a repeater located adjacent the vehicle'"'"'s audio system antenna and wherein the repeater downconverts, without demodulation, the high frequency carrier and includes an FM transmitter that transmits the audio source signal, in compliance with government regulations, to the vehicle'"'"'s audio FM system, via the vehicle'"'"'s FM antenna, without signal degradation.

29. A method for receiving an audio signal from a portable audio source on a vehicle'"'"'s FM tuner having an FM tuner antenna wherein the FM tuner lacks an input jack for coupling to the portable audio source, said method comprising:
-
inputting to a transmitter an FM frequency channel setting that corresponds to a channel to which the vehicle'"'"'s FM tuner is tuned; generating a first frequency carrier signal including the audio signal therein, provided from the audio source to said transmitter, and transmitting said first frequency carrier signal to form a first transmitted signal; receiving, by a self-powered repeater, said first transmitted signal and downconverting it, without demodulating it, to an FM frequency band carrier signal; transmitting, from a repeater antenna, said FM frequency band carrier signal to form a second transmitted signal; and receiving said second transmitted signal by the vehicle'"'"'s FM tuner antenna. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A wireless FM repeater system for converting an audio signal from a portable audio source and transmitting it to a vehicle'"'"'s FM tuner having an FM tuner antenna where the FM tuner lacks an input jack for coupling to the portable audio source, said system comprising:
-
a digital transceiver, coupled to the audio source, for digitizing the audio signal and digitally modulating a first frequency carrier signal with said digitized audio signal to form continuous digital audio that is streamed over a bi-directional link with a self-powered repeater, said transmitter comprising a channel select that permits a user to provide said transceiver with an FM frequency channel setting to which the vehicle'"'"'s FM tuner is tuned; and said repeater receiving said continuous digital audio and decoding said continuous digital audio, said repeater converting said decoded continuous digital audio into analog audio signals, said repeater comprising an FM frequency band transmitter which modulates an FM frequency band carrier signal with said audio signals to form an FM band transmitted signal that is transmitted by a repeater antenna and that is received by the FM tuner antenna. - View Dependent Claims (50, 51, 52, 53, 54, 55)
