20130045695 | TRANSMITTING AND RECEIVING RADIO SIGNALS IN VARIOUS FREQUENCY RANGES - A device transmits and receives radio signals, in particular radio signals in a cellular radio network. The device contains a first transmitting antenna for transmitting radio signals and a second receiving antenna. The antennas transmit and/or receive radio signals in different frequency ranges. The antennas are connected to a common cable connection via a radio signal splitter, by which cable connection the device can be connected to a radio terminal. The device contains a first radio signal amplifier disposed in a first radio signal path and/or a second radio signal amplifier disposed in a second radio signal path. The transmitting antenna and the receiving antenna have attenuation with respect to feedback of a radio signal transmitted from the transmitting antenna to the receiving antenna due to the arrangement thereof relative to each other and due to the transmitting and/or receiving characteristics thereof. | 02-21-2013 |
20120170519 | METHOD FOR CONNECTING SIGNAL PATHS, AND FUNCTION GROUP DESIGNED THEREFOR - A method and system for connecting signal paths in a circuit arrangement with multiband capability for processing and/or influencing signals in radio communication, on the basis of which at least the transmission paths of a corresponding circuit arrangement are activated or deactivated on the basis of the presence of a transmitted signal from a terminal which is operated with the circuit arrangement. The transmission paths, which are deactivated in a basic state of the circuit arrangement, are periodically checked in succession for the presence of a transmitted signal from the terminal with a multiplexer that forms a functional component of a detection unit and that is switched through by a controller for sequential scanning of the transmission paths for the presence of such a transmitted signal. If a signal is present, only a transmission path for the correct frequency band of the transmitted signal is activated and continuously checked for the presence of a transmitted signal. | 07-05-2012 |
20110116422 | RADIO TRANSMISSION SIGNAL DETECTION CIRCUIT - A detection circuit has a detector unit for detecting a transmitted signal from a mobile radio terminal. The detection circuit forms a part of a circuit arrangement for processing or influencing received signals and transmitted signals associated with the mobile radio terminal (accessory circuit). It is involved in the accessory circuit via a switching means, which is arranged in a transmission path upstream of at least one transmission power amplifier which can be activated upon detection of a transmitted signal, and is coupled to the transmission path via a coupling element which is arranged downstream of the transmission power amplifier. At the start of the transmission burst, the whole power of the transmitted signal is first of all supplied to the detector unit before said detector unit changes over the transmitted signal to the transmission power amplifier by operating the switching means. The detection circuit has a self-hold function, so that the detector unit leaves the accessory circuit in its operating state which is provided for the presence of a transmitted signal, even after the switching means has been changed over, at least until the transmission power amplifier has completed the circuit and the component of the amplified transmitted signal which is coupled out by means of the coupling element is applied to the detector unit. | 05-19-2011 |
20090305746 | Device for Coupling and Housing a Mobile Telephone in a Motor Vehicle - A system for accommodating a mobile telephone in a compartment in a motor vehicle. The compartment is electromagnetically shielded against the emission of radio signals from the mobile telephone. The system includes a connector for transmitting an antenna signal from an antenna of the motor vehicle to the mobile telephone, an electromagnetically shielded housing with an opening for inserting the mobile telephone into the housing and for removing the mobile telephone from the housing, and an elastically deformable retaining element that is designed to be electromagnetically absorbing. In a closed state of the housing in which the opening of the housing is at least partially closed, the opening at least partially shields against the emission of radio signals of the mobile telephone from the housing. In the closed state the retaining element secures the mobile telephone in a temporary position. | 12-10-2009 |
