  • Patent number: 10090902
    Abstract: One embodiment is directed towards a distributed antenna system (DAS). The DAS includes a host unit a plurality of remote units communicatively coupled to the host unit. The plurality of remote units are configured to implement a common arrangement of resource blocks for uplink transport signals. The host unit is configured to instruct a subset of the plurality of remote units to send a digital sample stream over a monitor path of their respective uplink transport signals. One or more simulcast modules are configured to sum the monitor paths from the respective uplink transport signals to generate a summed digital sample stream, the one or more simulcast modules configured to send the summed digital sample stream to the host unit. The host unit is configured to provide a signal based on the summed digital sample stream to one or more signal analysis modules.
