摘要： A mobile testing system for optimizing wireless coverage in a distributed antenna system is disclosed. In some aspects, the mobile testing system includes a measurement receiver that can determine signal levels for a respective signals communicated via the distributed antenna system. A processing device of the mobile testing system can identify a subset of the signals by decoding a respective identifier encoded in each of the subset of signals. The identifiers specify that the subset of signals is targeted to at least one coverage zone in which the mobile testing system is located. A subset of signal levels is obtained by the measurement receiver that corresponds to each of the subset of signals. The processing device can generate coverage contour data based on the subset of signal levels that describes signal coverage for at least one coverage zone.

摘要： A digital repeater system for repeating RF signals can include a receiving section for receiving an RF input signal that includes a frequency band with at least one subband associated with a communication channel of a telecommunications network. The receiving section can digitize the RF input signal to obtain a digital signal. A filter device includes a digital filter with a passband for filtering the digital signal. The digital filter is configurable by setting filter coefficients. A gain control device can set the gain of at least a portion of the digital signal. A transmitting section can transmit an RF output signal and can convert the digital signal to the RF output signal for transmission. A control unit can configure the filter coefficients of the digital filter based on the gain setting of the gain control device.

摘要： A repeater system includes a first master unit and a second master unit located on the movable object, such as a train. The master units are each connected to an antenna for receiving a downlink RF signal from at least one base station outside of the movable object and for transmitting an uplink RF signal towards the base station. Remote units are associated with different coverage areas within the movable object and are connected to the master units unit via a transport medium. The remote units are each connected to an antenna system for transmitting the downlink RF signal into the associated coverage area of the movable object and for receiving the uplink RF signal from the coverage area. A control unit can control first gain for the connection with the first master unit and a second gain for the connection with the second master unit.

摘要： A repeater system (1) comprising a front end section (10) constituted to, in a downlink direction, receive signals from multiple communication sources (3, 4, 7, 8, 9) associated with different operators and located outside of a coverage area (20) of the repeater system (1) and to, in an uplink direction, transmit signals to the at least one communication source (3, 4, 7, 8, 9). The repeater system further comprises a back end section (13, 14) constituted to, in the downlink direction, transmit an RF communication signal into the coverage area (20) and to, in the uplink direction, receive an RF communication signal out of the coverage area (20). Herein, in the downlink direction the front end section (10) combines multiple signals from multiple communication sources (3, 4, 7, 8, 9) into a combined signal common to all operators and to transmit the combined signal to the back end section (13, 14), wherein the back end section (13, 14) produces, from the combined signal, the RF communication signal for transmission into the coverage area (20). In the uplink direction the back end section (13, 14) produces, from a received RF communication signal, a combined signal, wherein the front end section (10) produces multiple signals from the combined signal received from the back end section (13, 14) for transmission to the multiple communication sources (3, 4, 7, 8, 9). By these means a repeater system is provided which may provide an approved coverage in a coverage area with the potential of high data rates for communication links in that coverage area.
