Problems solved by technology

[0016] A disadvantage of DE 10 2013 207 898 A1 is that the detection device does not allow a distinction between which mobile radio frequency bands are active and which are not in order to control the amplification device in a targeted manner

Embodiment Construction

[0055] figure 1 The use of the mobile radio compensator 1 according to the invention in a motor vehicle 2 for compensating attenuations present on the signal path 3 between, for example, the mobile radio 4 and the vehicle antenna 5 is explained.

[0056] The mobile radio compensator 1 comprises a mobile radio device-side interface device 6a to which, for example, a coupling device 7 can be connected, which can be designed, for example, as a coupling housing (sometimes also referred to as a “base frame”). The mobile radio device 4 can, for example, be stored or inserted into the coupling case. The coupling device 7 can establish a signal transmission with the mobile radio device 4 in any suitable manner, for example electromagnetically, galvanically, inductively and / or capacitively.

[0057] In contrast, the mobile radio compensator 1 also includes an antenna-side interface device 6b. An antenna arrangement 5 of the motor vehicle 2 , which includes at least one vehicle antenn...

Abstract

The invention relates to a mobile radio compensator that comprises an adjustable signal-level amplification means and a central detection means in order to detect the signal level of the transmissionsignals. An adjustment and / or control means can adjust a signal amplification, produced by the signal-level amplification means, of the transmission signals on the basis of the signal level detected by the detection means. A decoupling means comprising at least two decoupling signal paths is provided, wherein the decoupling signal paths are connected to a power adding means of which the output isin turn connected to the detection means (13). The decoupling means comprises a filter means which is arranged on or in the at least two decoupling signal paths, wherein the pass-bands for each of theat least two decoupling signal paths differ. The decoupling signal paths comprise an adjustable amplification means, which are alternately switched on and off by the adjustment and / or control means.

Description

technical field [0001] The invention relates to a mobile radio compensator for use in a motor vehicle for compensating signal attenuation when transmitting signals from or to a mobile radio device, and to a motor vehicle. Background technique [0002] It is known to construct mobile radio networks cellularly for the widest possible coverage. Mobile radio cells are usually formed by base stations on which fixed mobile radio antennas are usually mounted. [0003] The antennas of the base stations "illuminate (ausleuchten)" the corresponding cells, with the result that participants who are located in these mobile radio cells and usually move carry out communication with the base station and can thereby, for example initiate communication with also other mobile radio cells. A conversation with other participants in a network or in a fixed network. [0004] Communication between a base station and a mobile radio device in a mobile radio cell is known to take place using radio ...
