  • Patent number: 8743718
    Abstract: A method for calculating delay in a distributed antenna system includes sending a ping initiation message from a remote node to a host node in a distributed antenna system. The ping initiation message uniquely identifies a first communication port of the remote node to the host node with a unique identification. The method also includes receiving a ping reply message at the remote node. The ping reply message corresponds to the ping initiation message and also uniquely identifies the first communication port of the remote node with the unique identification. The method also includes determining, at the remote node, whether the ping reply message corresponds to the first communication port of the remote node based on the unique identification. The method also includes, when the ping reply message corresponds to the first communication port of the remote node, calculating the round-trip time delay between sending the ping initiation message and receiving the ping reply message at the remote node.

  • Patent number: 8306563
    Abstract: System and methods for muting a digital link in a distributed antenna system are provided. In one embodiment, a device for processing signals a distributed antenna system (DAS) is provided. The device comprises: a first signal path for transporting digital data signals; a controller for monitoring events affecting the first signal path; and a muting module coupled to the controller, wherein the muting module controls muting of a signal power of the first signal path as directed by the controller. The muting module applies a hard clamping to mute the signal power of the first signal path when the controller identifies an unplanned event. The muting module applies a ramp to mute the signal power of the first signal path when the controller identified a planned event.
