  • Patent number: 10785827
    Abstract: A master unit and a remote unit is provided for a multiband transmission system for distributing and combining signals of at least one wireless communication network and at least one digital network. A reference frequency generator is arranged in the master unit, the reference frequency generator being designed to clock a master modem for converting the signals of the at least one digital network. The reference frequency signal emitted by the reference frequency signal is restored via a reference frequency receiver and is used for closing a remote modem that is located there for demodulation.

  • Patent number: 10651893
    Abstract: In one embodiment, a TDD repeater system comprises: a master unit comprising separate uplink and downlink signal paths defined therein, and configured to couple in an uplink direction to a base station and in a downlink direction to at least one remote antenna unit, wherein the uplink path communicates uplink communication signals, wherein the downlink path communicates downlink communication signals; a switch configured to change direction of signal transmissions within the master unit between the uplink communication signals and the downlink communication signals; a synchronizing unit is configured to receive via the downlink signal path a clock signal from the downlink communication signals, wherein the synchronizing unit supplies a control signal to the switch corresponding to the clock signal; wherein the switch swaps the direction of signal transmissions within the master unit between the uplink communication signals and the downlink communication signals in response to the control signal.

  • Patent number: 10623340
    Abstract: Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous communication frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming communication frames based on frame information extracted from previously received communication frames. For example, a remote unit can be configured to receive one or more communication frames, each of the one or more communication frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next communication frame. The remote unit can extract the payload data from the next communication frame based on the predicted value for the additional start-of-frame field.

  • Patent number: 10499253
    Abstract: A distributed antenna system is provided for communicating with a plurality of base stations. The distributed antenna system includes a system controller and a master unit communicating with at least one of the plurality of base stations. A remote unit communicates over a high data rate media with the master unit and/or a downstream remote unit. Alternatively, the distributed antenna system includes a controller and a digital time/space crosspoint switch controlled by the controller. A digitizing transceiver is in communication with the digital time/space crosspoint switch. The crosspoint switch is configured to transmit and receive digital data through the digitizing transceiver.

  • Patent number: 10251154
    Abstract: Certain features relate to configuring a remote unit in a distributed antenna system (DAS) to switch between a baseband mode of operation and a measurement receiver mode of operation. In the baseband mode of operation, the remote unit can transmit a subset of baseband channels to a head-end unit or an extension unit of the DAS. The subset of baseband channels can carry wireless communication information. In the measurement receiver mode, the remote unit can transmit wideband data to the head-end unit or the extension unit of the DAS. The wideband data can include one or more of a measurement data for additional baseband channels other than the subset of baseband channels and information for use by the head-end unit to modify a configuration of the distributed antenna system.

  • Patent number: 9929980
    Abstract: Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous Ethernet frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming Ethernet frames based on frame information extracted from previously received Ethernet frames. For example, a remote unit can be configured to receive one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next Ethernet frame. The remote unit can extract the payload data from the next Ethernet frame based on the predicted value for the additional start-of-frame field.
