摘要： Embodiments disclosed herein include combining power from isolated power paths for powering remote units in distributed antenna systems (DASs). In one example, a remote unit(s) is configured to include multiple input power ports for receiving power from multiple power paths. The received power from each input power port is combined to provide a combined output power for powering the remote unit. Thus, a remote unit can be powered by the combined output power. To avoid differences in received power on the multiple input power ports causing a power supply to supply higher power than designed or regulated, the input power ports in the remote unit are electrically isolated from each other. Further, the received power on the multiple power inputs ports can be controlled to be proportionally provided to the combined output power according to the maximum power supplying capabilities of the respective power supplies.

摘要： Optimizing performance between a wireless distribution system (WDS) and a macro network(s). In this regard, a macro network optimization system is configured to detect a performance indicator(s) between a WDS and a macro network and optimize the performance of the macro network based on the detected performance indicator(s). The macro network optimization system analyzes a macro network performance report provided by the macro network and/or a WDS performance report provided by the WDS to detect the performance indicator(s) between the WDS and the macro network. The macro network optimization system reconfigures operations of one or more macro network elements to optimize performance between the WDS and the macro network based on the detected performance indicator(s). By detecting and optimizing performance between the WDS and the macro network, capacity, throughput, and/or coverage of the WDS and the macro network can be improved, thus providing better quality of experience (QoE).

摘要： Power management techniques in distributed communication systems in which the power available at a remote unit (RU) is measured and compared to the power requirements of the RU. Voltage and current are measured for two dummy loads at the RU and these values are used to solve for the output voltage of the power supply and the resistance of the wires. From these values, a maximum power available may be calculated and compared to power requirements of the RU.

摘要： Individualized gain control of remote uplink band paths in a remote unit in a distributed antenna system (DAS) based on combined uplink power level in the remote unit. The combined uplink power of a combined uplink communications signal in a remote unit is measured. If the combined uplink power level exceeds a defined uplink threshold power level for the remote unit, the gain is reduced for individual uplink band paths that provide a higher power contribution to the combined uplink power of combined uplink communications signal in the remote unit. This allows the initial uplink gain of the uplink band paths in a remote unit to be set higher to increase sensitivity, because the gain of the uplink band paths providing higher power contributions to the combined uplink power in the remote unit can be reduced, without reducing gain in other uplink band paths of the remote unit.

摘要： A voltage controlled optical directional coupler (VCODC) having a coupling ratio that can be adjusted to any desired value through voltage tuning is disclosed. The VCODC may include a first optical hybrid coupler and a second optical hybrid coupler, which may be coupled with each other via one or more voltage controlled optical elements having a variable transparency depending on a voltage applied to the one or more voltage controlled optical elements.

摘要： Determining noise levels in frequency band(s) for communications paths in distributed antenna systems. Noise may be induced in communications paths in distributed antenna system as a result of electromagnetic interference from communications media located in close proximity and/or from other electronic devices. Noise induced on communications media may not be evenly distributed across the frequency spectrum, but instead concentrated in certain portions of the frequency spectrum. The frequency band(s) of communication signals distributed in the distributed antenna systems are therefore adjusted to be provided outside of frequency band(s) having unacceptable noise levels. Using frequency bands outside of high noise level bands improves system performance (e.g., the signal-to-noise (S/N) ratio) in the distributed antenna system.

摘要： Time-division duplexing (TDD) in distributed communications systems, including distributed antenna systems (DASs) is disclosed. In one embodiment, a control circuit is provided and configured to control the TDD transmit mode of a DAS to control the allocation of time slots for uplink and downlink communications signal distribution in respective uplink path(s) and downlink path(s). The control circuit includes separate power detectors configured to detect either a transmit power level in a downlink path or a receive power level in an uplink path. If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.
