A telecommunications system including a processor and a non-transitory computer-readable medium storing a signal distribution engine is provided. The signal distribution engine is executable by the processor device to detect incoming signals received by a DAS that includes a headend unit coupled to RAU(s) using a communication cables or optical fiber; determine information about the detected signals; assign specified signals received by the DAS to a specified RAU in response to a user input via a signal distribution graphical user interface, which includes representations of and associations between the specified signals, headend unit, and RAU(s), that manually associates the specified signals with the specified remote antenna unit; and in response to the user input, output instructions regarding how to route the specified signals from the headend unit to the specified remote antenna unit over a communication cable or optical fiber communicatively coupled to the specified remote antenna unit.

Signal distribution interface

Systems and methods for optimized telecommunications distribution are provided. For example, a distributed antenna system can include a master unit for transceiving signals with remote units operable for wirelessly transceiving signals with mobile devices in a coverage area. A self-optimized network analyzer can be in a unit of the distributed antenna system. A self-optimized network controller in the distributed antenna system can output commands for changing operation of a component in the distributed antenna system in response to analysis results from the self-optimized network analyzer. In some aspects, the master unit includes base transceiver station cards for receiving call information in network protocol data from a network and for generating digital signals including the call information from the network protocol data for distribution to the remote units.

Optimized telecommunications distribution system

A direct current (DC) power distribution system is provided. The system includes a passive splitter and an active splitter. The passive splitter includes an input port that is configured to receive a first DC power input and multiple output ports that are configured to provide a first DC power outputs to corresponding ones of multiple power only devices. The active splitter includes an input port that is configured to receive a second DC power input and network data corresponding to at least one network communications data channel and multiple output ports that are configured to provide second DC power outputs and network communications data to corresponding power and/or data devices.

Apparatus and systems for providing DC power using communication networks

A user interface for a distributed antenna system (DAS) is provided. When executed by a processor, a signal distribution engine receives information about signals transported by the DAS and components of the DAS. The signal engine generates a signal set assignment user interface including a list of signals transported by the DAS and a signal set formation area for receiving a signal set. The signal engine also generates a signal distribution user interface that includes representations of signal sets, hardware components, and associations between hardware components. In response to receiving a request to associate the signal set with a specified hardware component, a command is output to configure a signal path so that signals in the signal set are provided to the specified hardware component.

The present disclosure relates to transport link quality measurement in a distributed antenna system. A link quality indicator associated with the functional performance of a digital transport link in the distributed antenna system can be determined by a component of the distributed antenna system. An indication of a potential fault condition can be determined based on the link quality indicator before a fault condition associated with the potential fault condition occurs. The indication of the potential fault condition can be presented, for example, via a graphical user interface, a table, or an email alert.

Distributed antenna system transport link quality measurement

Certain features relate to configuring a distributed antenna system ('DAS') to interface with and manage components of facility control and monitoring systems while providing wireless communications in a cellular or public safety network. A communications module is configured for receiving facility control signals from facility control and monitoring centers and associated nodes and sensors. A signal processing module is configured to convert the facility control signals a format transportable in the DAS. The signal processing module is also configured to multiplex the facility control signals with mobile voice and data signals being transported in the DAS. The DAS configured to manage components of facility control and monitoring systems can route facility control signals to appropriate facility control centers or the nodes and sensors associated with the facility control centers.

Telecommunications system for transporting facility control data and wireless coverage information

Certain aspects involve power management subsystems for a distributed antenna system ('DAS') or other telecommunication system. The power management subsystem can include a measurement module and an optimization module. The measurement module can monitor a utilization metric for a remote unit in the DAS or other telecommunication system. The power optimization module can determine whether the remote unit is underutilized based on the monitored utilization metric. The power optimization module can configure the remote unit for a low-power operation in response to determining that the remote unit is underutilized.

Power management for distributed antenna system

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.

Reconfigurable single and multi-sector cell site system

Certain aspects involve distributing power in a distributed antenna system. A subsystem of the distributed antenna system can receive key performance indicators for remote units and system factors that affect the key performance indicators. The subsystem can determine a radio frequency power to achieve key performance indicators based on the one or more system factors and configure the remote units to operate at the radio frequency power.

Power allocation in distributed antenna systems based on key performance indicators

Systems and methods for automatically configuring a distributed antenna system are provided. A configuration sub-system of the distributed antenna system can identify signal parameters for downlink signals received from one or more base stations via inputs of a unit in the distributed antenna system. The configuration sub-system can automatically determine a configuration plan for the distributed antenna system based on the automatically identified signal parameters. The configuration plan specifies how to combine subsets of the downlink signals for routing to remote antenna units of the distributed antenna system.

Automatic configuration sub-system for distributed antenna systems

A remote unit of a distributed antenna system includes: a transceiver configured to communicate RF signals between a master unit of the distributed antenna system and a terminal device, and receive downlink RF signals from a base station; and signal processing circuitry configured to provide downlink signals to the master unit. The remote unit receives instructions from a host unit of the distributed antenna system to establish a communication link with the base station in response to detecting a malfunction with respect to an additional communication link between the master unit and an additional base station.

Remote unit for communicating with base stations and terminal devices

A remote unit of a distributed antenna system is disclosed that can communicate analog RF signals with both base stations and terminal devices in a coverage zone serviced by the remote unit. In some aspects, the remote unit can include a signal processing module and a transceiver. The transceiver can communicate RF signals between a master unit of the distributed antenna system and a terminal device. The transceiver can also receive analog downlink RF signals from a base station. The signal processing module can convert the analog downlink RF signals to digital downlink signals and provide the digital downlink signals to the master unit.
