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

摘要

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.

1. An interface module for a unit designed to transmit and/or amplify communication signals inside an antenna distribution system, the interface module comprising:
a first analog interface for forwarding and receiving communication signals from mobile terminals; a second interface for forwarding and receiving communication signals from the antenna distribution system; at least one signal path for forwarding the received communication signals between the first and second interfaces; a controllable digital unit in the signal path that is configured for digitizing incoming communication signals to digital signals and converting outgoing communication signals to analog signals, the controllable digital unit being configured to evaluate characteristic signal parameters of the digital communication signals and, based on the evaluation, to select a subset of signals from the digital communication signals wherein the selected subset is separate from remaining communication signals, the controllable digital unit further configured for processing and forwarding the selected subset of signals apart from the remaining communication signals; a communication unit coupled with the controllable digital unit and configured for receiving control data for determining how the subset of signals is processed and forwarded.
