Mobile wireless device for a motor vehicle, and method for operating the mobile wireless device
First Claim
1. A mobile radio apparatus for a motor vehicle, comprising:
- one or more processors to implement;
a first mobile radio module to interchange a first mobile radio signal with a first external mobile radio station via a first signal connector of the first mobile radio module, the first mobile radio signal being based on at least one first mobile radio standard; and
a second mobile radio module to interchange a second mobile radio signal with a second external mobile radio station via a second signal connector of the second mobile radio module, the second mobile radio signal being based on a second mobile radio standard, the second mobile radio standard being different from the first mobile radio standard;
first and second antennas to selectively transmit the first and second mobile radio signals; and
a switch connected to the first and second antennas and to the first and second signal connectors, to change over, based on a switching signal, between a first switching state, in which the first signal connector is coupled to the first antenna and the second signal connector is coupled to the second antenna, and a second switching state, in which the first signal connector is coupled to the second antenna and the second signal connector is coupled to the first antenna, whereinthe switching signal is produced so as to switch the switch to the second switching state at a beginning of a voice transmission and to maintain the switch in the second switching state during voice telephony.

Abstract
A mobile radio apparatus for a motor vehicle has a first mobile radio module and a second mobile radio module. Furthermore, a first antenna and a second antenna are provided for transmitting mobile radio signals. To provide robust voice telephony for the motor vehicle that can be implemented with little circuit complexity, a switching device is connected to the antennas and to a respective signal connection of the mobile radio modules and that is designed to take a switching signal as a basis for changing over between a first switching state, in which the first signal connection is coupled to the first antenna and the second signal connection is coupled to the second antenna, and a second switching state, in which the first signal connection is coupled to the second antenna and the second signal connection is coupled to the first antenna.
