摘要： A telecommunications system is provided that is controllably operable as a sectorized antenna system and as an omnidirectional antenna system without requiring hardware reconfiguration. The telecommunications system includes a phase correlation measurement unit that can be between a sectorized antenna sub-system and a remotely located RF source site. The phase correlation measurement unit can be coupled to the RF source site over at least one feed line. The phase correlation measurement unit can output signals for controlling a phase shifter at the RF source site for phase shifting downlink signals and for causing operation of the sectorized antenna sub-system as an omnidirectional antenna sub-system. In a sectorized operation mode, the phase correlation measurement unit and the phase shifter can be inactivated.

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 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.

摘要： The invention relates to a master unit (2, 2') and a remote unit (3) for a multiband transmission system (1) for distributing and combining signals of at least one wireless communication network and at least one digital network. According to the invention, a reference frequency generator (12) is arranged in the master unit (2), said reference frequency generator being designed to clock a master modem (5, 5', 6, 6') for converting the signals of the at least one digital network. The reference frequency signal emitted by the reference frequency generator (12) is transmitted to the remote unit (3) in the downlink direction (DL). There, the reference frequency signal is restored by means of a reference frequency receiver (40) and used for clocking a remote modem (38, 38', 39, 39') that is located there for demodulation.

摘要： Certain aspects involve an interface device for a distributed antenna system (“DAS”). In some aspects, the interface device can include an interface, a power detector, and a processor. The interface can include one or more ports for communicatively coupling the interface device to a base station and a switch that is switchable between first and second configurations. The first configuration connects a port to a downlink path of the DAS, and the second configuration connects the port to a signal reflection path. The processor can switch the switch between the first and second configurations based on a signal power measured by the power detector at the port. In other aspects, the interface device can include additional ports and termination loads. The processor can cause a signal path to be connected to a termination load instead of a port based on the port being disconnected from a unit of the DAS.
