摘要： Certain aspects are directed to a configuration sub-system for telecommunication systems. The configuration sub-system can include a test signal generator, a power measurement device, at least one additional power measurement device, and a controller. The test signal generator can be integrated into components of a telecommunication system. The test signal generator can provide a test signal to a signal path of the telecommunication system. The power measurement device and the additional power measurement device can respectively be integrated into different components of the telecommunication system. The power measurement device and the additional power measurement device can respectively measure the power of the test signal at different measurement points in the signal path. The controller can normalize signals transmitted via the telecommunication system by adjusting a path gain for the signal path based on measurements from the power measurement device and the additional power measurement device.

摘要： Repeater systems and methods are disclosed. In one embodiment, a repeater system located within a coverage area comprises: a host configured to combine multiple downlink signals from multiple communication sources located outside the coverage area into a first combined downlink signal; at least one remote coupled to the host and configured to transmit the first combined downlink signal as a second downlink RF communication signal to terminals within the coverage area. The at least one remote is configured to produce a combined uplink signal from multiple uplink signals received through multiple communication links from the terminals, and configured to forward the combined uplink signal to the host. The host produces multiple signals from the combined uplink signal for transmission to the multiple communication sources, wherein a first of the plurality of terminals communicates with a different one of the multiple communication sources than a second of the plurality of terminals.

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.

摘要： A distributed antenna system includes a plurality of remote antenna units with a passive element coupled to at least one of the remote antenna units at a connection juncture. An RFID system is associated with the first passive element and has RFID data identifying the first passive element. An interrogator unit is associated with the remote antenna unit and is configured for generating a least one signal for transmission to the passive element to be reflected at the connection juncture and received at the interrogator unit. The interrogator unit is also configured for generating at least one signal for transmission to the RFID system to obtain the RFID data identifying the passive element. Processing circuitry processes the reflected signal and measures a parameter of the first passive element. The processing circuitry correlates the measured parameter with the RFID data for the passive element.

The repeater (1) comprises a master unit (2) for communicating with a base station (3) of a wireless network, at least one remote unit (4) for communicating with a network terminal, as well as a waveguide (11) connecting the remote unit (4) with the master unit (2) for transmitting the communication signals in an uplink direction (6) from the remote unit (4) to the master unit (2) and in a downlink direction (5) from the master unit (2) to the remote unit (4). Both the master unit (2) and the remote unit (4) comprise one switch (19, 20) each for changing over the signal transmission between uplink direction (6) and downlink direction (5). Both switches (19, 20) are selected by a synchronizing unit (21) arranged in the master unit (2), the synchronizing unit (21) being designed for determining a clock pulsing from the communication signal fed to the master unit (2)—in particular from the base station (3)—and for supplying a control signal corresponding to this clock pulsing to the switches (19, 20).

摘要： Aspects and features are directed to an uplink integrity detection sub-system. In one aspect, a distributed antenna system is provided that includes a remote antenna unit that communicates with wireless devices in a coverage area, additional remote antenna units that communicate with wireless devices in additional coverage areas, and a unit that communicates with the remote antenna unit and the additional remote antenna units. The unit includes a distributed antenna system controller. The distributed antenna system controller can determine that an undesirable signal component having a power level exceeding a threshold power is communicated via an uplink path from the remote antenna unit. The distributed antenna system controller can also minimize an impact of the undesirable signal component on the additional coverage areas of the additional remote antenna units. Minimizing the impact can include modifying the gain of the uplink path over which the undesirable signal component is communicated.
