The invention relates to a repeater system for forwarding radio signals. The repeater system comprises a donor unit for converting the frequencies of the radio signals from the transmission frequency to an intermediate frequency; a server unit for converting the converted radio signals from the intermediate frequency to the transmission frequency; and a cable, which connects the donor unit and the service unit and transmits the converted radio signals over a distance between the donor unit and the service unit at the intermediate frequency. The donor unit has an uplink donor antenna and a separate downlink donor antenna and/or the service unit has an uplink service antenna and, at the same time, a separate downlink service antenna.

Repeater system

A mobile communications transmission system provides a plurality of mobile communications cells in a building or campus. It comprises a first baseband unit and a first gateway device, which is connectable to a data network. At least one transceiver unit is connected to the first baseband unit. The at least one transceiver unit is configured to provide at least one first mobile communications cell. By way of this first mobile communications cell, a subscriber device in the building can exchange information with the data network. A first control device is connected to the first baseband unit and the first gateway device. The first baseband unit and the first gateway device are installed in the building or campus in which the at least one transceiver unit provides the at least one first mobile communications cell, whereas the first control device is accommodated remote therefrom at an operating company.

Mobile communications transmission system for providing a multiplicity of mobile communications cells in a building or campus

A distributed antenna system with a plurality of remote radio units is disclosed. The distributed antenna system includes a jammer signal generator for generating a jammer signal in at least one frequency range to be blocked on detection of an uplink signal in a coverage area, as well as at least one antenna element for transmitting the generated jammer signal in the coverage area. The jammer signal will ensure that any mobile devices or stations within the coverage area are unable to transmit radio signals as the frequency range(s) on which the radio signals should be transmitted are blocked by the jammer signal.

Method and system for producing a jammer signal

An antenna transmission control device has a base-station-side and an antenna-side multiplexer circuit. There is an alternating protocol transfer between these two multiplexer circuits to control components close to the antenna. The current-alarmed or protocol-alarmed signals present at the antenna-side terminals of the multiplexer provided on the antenna side can be measured or detected by the multiplexer circuits and supplied to the transmission link together with a terminal-dependent or load-dependent protocol.

Antenna system, in particular mobile communication antenna system, and associated transmission and control device

An improved GPS mast module is characterized by the following features: the GPS mast module may be connected in a HF main transmission line () between a base station (BS) and an antenna assembly (ANT), in particularly a mobile radio installation, and the satellite signals from an internal or connectable GPS antenna (GPS-ANT) can be supplied by a directional coupler () to the HF main path ().

A multi-beam-shaping structure is distinguished by the following features: the multi-beam-shaping structure is provided with at least one electronic communication interface for controlling the multi-beam-shaping structure for setting the at least two radiation diagrams differently, the multi-beam-shaping structure comprises at least one driver, preferably comprising an electric motor, and preferably a power unit, the multi-beam-shaping structure comprises at least two first mechanical interfaces and/or coupling points, a drive connection engages on each of the at least two first mechanical interfaces and/or coupling points, the at least one driver of the multi-beam-shaping structure is connected to the at least two mechanical interfaces and/or coupling points via a multidrive, it being possible to actuate selectively at least one of the plurality of drive connections in each case via the at least one driver and the associated controller, and the number of interfaces and/or coupling points being greater than the number of driver.

Multi-beam-shaping structure

An improved device for receiving and transmitting mobile telephony signals comprises at least 4 channels. Each of the at least 4 channels (K, K, K, K) can be controlled with a transmission signal, that is different from the other channels, which can be generated with a separate channel module (KM, KM, KM, KM) from various data streams. A controller device is provided for, via which several or all of the power amplifiers, which are connected in several or all channels (K; K, K, K, K), can be operated in-phase or phase-locked with each other, in such a way that the transmission signals (TX) amplified in the channels concerned (K; K, K, K, K) can be synchronized and interconnected. As a result, a transmission signal can be radiated with a higher transmission power.
