摘要： In an example, a configuration circuit includes a connector and a controller communicatively coupled to the connector via one or more signal lines. The configuration circuit further includes a microcontroller communicatively coupled to the controller via an interface. The configuration circuit further includes a connection detection circuit communicatively coupled to the microcontroller and the one or more signal lines. The connection detection circuit is configured to determine whether communication traffic between the connector and the controller on the one or more signal lines is detected, and output an interrupt signal to the microcontroller in response to detecting communication traffic between the connector and the controller on the one or more signal lines. The microcontroller is configured to instruct the controller to wake from a low-power sleep mode in response to receiving the interrupt signal from the connection detection circuit.

摘要： In an embodiment, a signal repeater includes a master unit and a remote unit that are optically coupled to one another by, e.g., an optical fiber. The master unit includes master-unit circuitry configured to receive an input electrical signal from a satellite-signal receive antenna, and to convert the input electrical signal into an optical signal. And the remote unit includes remote-unit circuitry configured to convert the optical signal into an intermediate electrical signal, to amplify the intermediate electrical signal to generate an output electrical signal, and to couple the output electrical signal to a retransmission antenna. Because an optical channel, such as an optical fiber, typically attenuates an optical signal significantly less per unit of distance than a coaxial cable attenuates an electrical signal, such a signal repeater allows a satellite receive antenna to be located at a significant distance from a retransmit antenna.

摘要： One embodiment is directed to a radio access network (RAN) system comprising a baseband unit (BBU), a plurality of remote radio units, wherein each of the remote radio units is located remotely from the BBU, and an intermediary unit The BBU, the remote radio units, and the intermediary unit are communicatively coupled to each other via a switched Ethernet network. The BBU is configured to transmit downlink fronthaul data to the intermediary unit via the switched Ethernet network. The intermediary unit is configured to receive the downlink fronthaul data from the BBU and simulcast the downlink fronthaul data to the remote radio units via the switched Ethernet network. Each remote radio unit is configured to receive the downlink fronthaul data and generate therefrom at least one downlink radio frequency signal for wireless communication to user equipment (UE) via an associated at least one antenna.

摘要： A re-configurable distributed antenna system that includes a plurality of base transceiver stations and a plurality of remote antenna units is provided. The plurality of the remote antenna units are configured and arranged to provide communication services for a plurality of coverage zones. A signal router selectively routes signal communication paths between a plurality of base transceiver stations and the plurality of the remote antenna units. At least one memory is configured to store routing scenarios and distributed antenna system configurations associated with the stored routing scenarios. Moreover, at least one controller dynamically controls the signal router to selectively route the signal communication paths between the plurality of base transceiver stations and the plurality of remote antenna units based at least in part on a then current need of communication service capacity within the plurality of coverage zones and the stored coverage routing scenarios.

摘要： A sequenced transmit muting wideband power amplifier is provided that includes at least one pre-driver stage having at least a first pre-driver and a second pre-driver. A mute switch selectively establishes a communication path between the first and second pre-drivers or couples the second pre-driver to a termination resistor. A pre-driver switch selectively activates/deactivates the first and second pre-drivers. A driver stage is in communication with the pre-driver stage and includes a first driver. A final amplifier stage is in communication with the driver stage and includes at least one second driver. At least one S-NBS switch is configured to selectively activate/deactivate the first driver and second driver. A controller is configured to activate the at least one pre-driver switch, the mute switch, the at least one S-NBS switch to selectively place the amplifier in one of a transmit mode and a mute mode.

摘要： A repeater with redundancy functions for a wireless communication system is provided. The repeater includes downlink repeater circuitry, uplink repeater circuitry, a detection function, at least one memory and a controller. The detection function is configured to detect conditions of communications between the base stations and the repeater. The at least one memory is used to store a primary configuration that sets out parameters for interfacing communications between the repeater and a primary base station of the base stations and at least one secondary configuration that sets out parameters for interfacing communications between the repeater and at least one secondary base station of the base stations and/or a secondary signal line of signal lines between the repeater and the primary base station. The controller is configured to implement the at least one secondary configuration to communicate with an associated secondary base station upon the detection function detecting abnormal communications between the repeater and the primary base station.
