In this regard, in one exemplary embodiment, a method for triggering channel handoffs in a DAS is provided. The method comprises routing a first channel of a communications service to a predetermined area in the DAS at a predetermined power level. The first channel provides a service to at least one network terminal in the predetermined area in the DAS. The method also comprises routing a second channel of a communications service to the predetermined area in the DAS. The method also comprises lowering a power level of the first channel to trigger handoff of the service to the at least one network terminal from the first channel to the second channel.

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： 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： Frequency shifting a communications signal(s) in a multiple frequency (multi-frequency) distributed antenna system (DAS) to avoid or reduce frequency interference is disclosed. Related devices, methods, and DASs are disclosed. Non-limiting examples of frequency interference include frequency band interference and frequency channel interference. As a non-limiting example, frequency interference in a multi-frequency DAS may result from non-linearity of a signal processing component generating an out-of-band harmonic of a first, in-use communications signal in a first frequency band, within different frequency band(s) of other in-use communications signal(s). To avoid or reduce such interference, embodiments disclosed herein involve predicting frequency interference that may result from processing received, in-use communications signals in multiple frequency bands to be distributed in a multi-frequency DAS. Frequency shifting is performed to avoid or reduce any interfering signal products produced from the signal processing of any in-use communications signals, from interfering in the frequencies of other in-use communications signals.

摘要： One embodiment of the disclosure relates to radio frequency (RF) communication channel reconfiguration in remote antenna unit (RAU) coverage areas in a distributed antenna system (DAS) to reduce RF interferences. In this regard, a spectrum optimization unit dynamically reconfigures RF communication channels employed by RAU coverage areas in a DAS to reduce or avoid adjacent-channel and/or co-channel RF interferences. Each of the RAU coverage areas provides a respective sniffed RF signal to the spectrum optimization unit. The spectrum optimization unit analyzes the respective sniffed RF signal to determine a respective lesser-interfered RF communication channel for an RAU coverage area and dynamically reconfigures the RAU coverage area to communicate on the respective lesser- interfered RF communication channel. By dynamically reconfiguring the RAU coverage areas to communicate on respective lesser-interfered RF communication channels, it is possible to reduce or avoid RF interferences to provide improved capacity, throughput, and coverage in the DAS.

摘要： Embodiments of the disclosure relate to digital interface modules (DIMs) for flexibly distributing digital and/or analog communications signals in wide-area analog distributed antenna systems (DASs). In this regard, in one aspect, a DIM is a multi-functional device capable of distributing the digital and/or analog communications signals to a local-area DASs in the wide-area DAS. The DIM comprises a digital communications interface for coupling with a digital signal source, an analog local distribution interface for coupling with an analog signal source, and at least one digital remote distribution interface for coupling with a head-end unit (HEU) of the local-area DAS. By employing the DIM in the wide-area DAS, it is possible to flexibly reconfigure the wide-area DAS for distributing digital and/or analog communications signals over the digital communications mediums.

摘要： Embodiments disclosed in the detailed description include supporting an add-on remote unit(s) (RU) in an optical fiber-based distributed antenna system (DAS) over existing optical fiber communications medium using radio frequency (RF) multiplexing. An existing DAS comprises at least one existing head end equipment (HEE) communicatively coupled to a plurality of existing RUs through an existing optical fiber communications medium. In aspects disclosed herein, an add-on RU is added to the existing DAS to support additional wireless communications. No new optical fibers are required to be deployed to support communications to the add-on RU in the existing DAS. Instead, the existing DAS is configured to support the add-on RU through the existing optical fiber communications medium using RF multiplexing. As a result, the add-on RU can be added to the existing optical fiber-based DAS without adding new optical fibers, thus leading to reduced service disruptions and deployment costs.
