Systems for transporting externally received signals within a motor vehicle

A system, comprising:

• a vehicle comprising:
• a device;
• an analog-to-digital converter;
• a digital-to-analog converter;
• a frequency conversion module;
• and
• an antenna;
• and
• an external apparatus outside the vehicle,
• wherein the device of the vehicle is configured to exchange high-frequency signals having a high value of frequency between the device of the vehicle and the external apparatus via the antenna of the vehicle using electromagnetic waves,
• wherein the antenna is connected via a first path to a first end of a line of the vehicle, and the device is connected via a second path to a second end of the line of the vehicle,
• wherein the analog-to-digital converter is arranged along at least the first path or the second path, and is configured to digitize the high-frequency signals prior to transport along the line,
• wherein the digital-to-analog converter along at least the first path or the second path is configured to analogize the signals after the transport along the line, and
• wherein the frequency conversion module is arranged along at least the first path or the second path.

A method for exchanging signals between a device of a vehicle and an external apparatus outside the vehicle, the method comprising:

• exchanging high-frequency signals having a high value of frequency between the device of the vehicle and the external apparatus via an antenna of the vehicle using electromagnetic waves;
• digitalizing, by an analog-to-digital converter of the vehicle, the high-frequency signals prior to transport along a line connecting the device of the vehicle and the antenna of the vehicle;
• analogizing, by a digital-to-analog converter, the high-frequency signals after transport along the line;
• adjusting, by a frequency reduction module of the vehicle, the high value of the frequency of the high-frequency signals to a low value prior to transport along the line;
• and
• adjusting, by a frequency increasing module, low-frequency signals back to the original high value of the frequency after transport along the line.
