Abstract: Transport of differential signals is provided. In one aspect, a telecommunications system includes a first unit and a second unit. The first unit can calculate a differential signal from an original signal. The differential signal can represent a change in signal levels between constant time intervals in the original signal. The second unit can estimate the original signal from the differential signal received from the first unit over a communication medium.

Abstract: Certain aspects involve selectively combining uplink transmissions in a distributed antenna system (“DAS”). For example, a unit of the DAS can receive baseband uplink transmissions from remote units of the DAS via a first channel and a second channel. The unit can generate a first combined uplink signal by combining baseband uplink transmissions received from a first subset of the remote units via the first channel that include data for transmission to a base station. The unit can generate a second combined uplink signal that includes baseband uplink transmissions received from a second subset of the remote units via the second channel and excludes or attenuates baseband uplink transmissions that are received from the first subset of the remote units via the second channel and that lack data for transmission to the base station are excluded or attenuated. The unit can transmit the combined uplink signals to the base station.

Abstract: A communication system includes a receive antenna for receiving communication signals, processing circuitry for processing the received communication signals and repeating the signals for further transmission and at least one transmit antenna for transmitting the repeated signals. The processing circuitry utilizes configurable settings for controlling the operation of the communication system and the configurable settings are variable for varying the operation of the system. The processing circuitry is further operable for receiving inputs regarding current operating conditions of the communication system and for selectively adapting the configurable settings of the system based upon the operating condition inputs.

Abstract: Embodiments are disclosed for extracting sub-bands of interest from signals in a frequency domain for transmission via a distributed antenna system. In one aspect, a transformed downlink signal is generated by performing a frequency transform on a downlink signal. The transformed downlink signal represents the downlink signal in a frequency domain. At least one sub-band of the transformed downlink signal is identified as including data to be transmitted via the distributed antenna system. The sub-band is extracted from the transformed downlink signal for transmission via the distributed antenna system.

Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

Abstract: 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.

Abstract: Certain aspects and aspects of the present invention are directed to a distributed antenna system having a downlink communication path, an uplink communication path, and a non-duplexer isolator sub-system. The downlink communication path can communicatively couple a transmit antenna to a base station. The uplink communication path can communicatively couple a receive antenna to the base station. In one aspect, the non-duplexer isolator sub-system can be electronically configured for isolating uplink signals traversing the uplink communication path from downlink signals. In another aspect, a non-duplexer isolator sub-system can be configurable in one or more mechanical steps selecting a frequency response. In another aspect, a non-duplexer isolator sub-system can include an active mitigation sub-system.
