System and method for performance optimization in and through a distributed antenna system

A system comprising:

• a plurality of Digital Remote Units (DRUs), each configured to receive wireless radio uplink signals and transmit wireless radio downlink signals, wherein a first DRU of the plurality, of DRUs is associated with a first geographic area and a second DRU of the plurality of DRUs is associated with a second geographic area;
• a plurality of inter-connected Digital Access Units (DAUs), each configured to communicate with at least one of the plurality of DRUs via optical signals and each being coupled to at least one base station;
• a plurality of stationary detectors, each configured to measure uplink power at one of the plurality of DRUs and motion of a train;
• and
• a train activity monitor, co-located at each DRU of the plurality of DRUs, communicatively coupled to the plurality of stationary detectors and configured to:
• monitor a level of train activity in a geographic coverage area for each of the plurality of DRUs using the measured uplink power and the measured motion of the train;
• and
• vary one or more wireless radio uplink signals in response to the measured uplink power and the level of train activity in the geographic coverage area for each of the plurality of DRUs by:
• transitioning an uplink gain toward zero for the first DRU in response to determining a decrease in monitored train activity in the first geographic area;
• and
• increasing power associated with the second DRU in response to determining an increase in monitored train activity in the second geographic area.
