A distributed antenna system includes at least one master unit communicatively coupled to at least one base station and a plurality of remote units located remotely from the at least one master unit. The plurality of remote units are communicatively coupled to the master unit over at least one transport communication link. The system is configured to distribute uplink and downlink signals between a base station and mobile units. A digital unit generates digital samples indicative of spectrum included in at least one of the uplink and downlink signals. A network interface communicates with an external computer. The digital unit is configured to process the digital samples and communicate information indicative of the spectrum to the external computer via the network interface.

Interface module for a unit of an antenna distribution system, and antenna distribution system

An interface module for a unit designed to transmit and/or amplify communication signals inside an antenna distribution system includes a first analog interface for forwarding and receiving communication signals from mobile terminals and a second interface for forwarding and receiving communication signals from the antenna distribution system. A signal path forwards the received communication signals between the first and second interfaces. A controllable digital unit in the signal path is configured for digitizing incoming communication signals to digital signals and converting outgoing communication signals to analog signals. The digital unit is configured to evaluate characteristic signal parameters of the digital communication signals and select a subset of signals from the digital communication signals. The controllable digital unit is further configured for forwarding the selected subset of signals.
