摘要： In one example, a system includes a central unit and a plurality of radiating points communicatively coupled to the central unit and located remotely from the central unit. Each respective radiating point includes a detector configured to evaluate uplink signals received from a coverage area of the respective radiating point. The detector is further configured to determine which services of a plurality of services supported by the system are needed and which services of the plurality of services supported by the system are not needed based on the evaluation of the uplink signals. The detector is further configured to send a request, to the central unit, to activate a service determined to be needed.

摘要： Repeater systems and methods are disclosed. In one embodiment, a repeater system located within a coverage area comprises: a host configured to combine multiple downlink signals from multiple communication sources located outside the coverage area into a first combined downlink signal; at least one remote coupled to the host and configured to transmit the first combined downlink signal as a second downlink RF communication signal to terminals within the coverage area. The at least one remote is configured to produce a combined uplink signal from multiple uplink signals received through multiple communication links from the terminals, and configured to forward the combined uplink signal to the host. The host produces multiple signals from the combined uplink signal for transmission to the multiple communication sources, wherein a first of the plurality of terminals communicates with a different one of the multiple communication sources than a second of the plurality of terminals.

摘要： A repeater system includes a first master unit and a second master unit located on the movable object, such as a train. The master units are each connected to an antenna for receiving a downlink RF signal from at least one base station outside of the movable object and for transmitting an uplink RF signal towards the base station. Remote units are associated with different coverage areas within the movable object and are connected to the master units unit via a transport medium. The remote units are each connected to an antenna system for transmitting the downlink RF signal into the associated coverage area of the movable object and for receiving the uplink RF signal from the coverage area. A control unit can control first gain for the connection with the first master unit and a second gain for the connection with the second master unit.

摘要： A repeater system including bi-directional amplifier circuitry that is configured for repeating signals between at least one device and a first signal source. Receiver circuitry is coupled with the amplifier circuitry provides at least one signal associated with at least one of a device or the first signal source or a second signal source. Controller circuitry is configured for monitoring a parameter of a provided signal that is reflective of a property of a signal source or a device. The monitored parameter is used to make a determination of whether repeated signals associated with the first signal source will desensitize the operation of the second signal source. The controller circuitry is also operable for adjusting the power level of the signals that are repeated by the bi-directional amplifier circuitry based on the determination that repeated signals will desensitize the operation of the second signal source.
