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.

Abstract: Method and apparatus for generating a jitter reduced clock signal from signal transmitted over a communication medium includes receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream. A recovered clock signal is generated from the modulated signal and tracks the long-term drift in the modulated signal. A jitter reduced clock signal is generated by filtering the recovered clock signal with a filtering circuit having a bandwidth sufficient to remove jitter while allowing the jitter reduced clock signal to track the drift in the modulated signal.

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: A system includes: a unit configured to communicate a modulated signal via a signal interface; and at least one additional unit configured to receive the modulated signal from the unit. The at least one additional unit includes circuitry configured to remove jitter from a recovered clock signal to generate a jitter reduced clock signal that tracks long-term drift in the modulated signal, wherein the at least one additional unit is configured to generate the recovered clock signal from the modulated signal.

Abstract: A system is provided for adjusting power provided over a channel to a device. The system can include power sourcing equipment and a sub-system. The power sourcing equipment can provide power to a powered device via a channel. The sub-system can determine an amount by which to increase the power based on a resistance of the channel. The power sourcing equipment or the powered device can adjust the power (or load) in response to a command from the sub-system. The sub-system can include at least one measurement device and a processor. The measurement device can measure an output voltage of the power sourcing equipment, an input voltage of the powered device, and a current on the channel. The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current. The processor can output a command specifying an increase or decrease in the level of power supplied by the power sourcing equipment.
