Abstract
Aspects and features are directed to an uplink integrity detection sub-system. In one aspect, a distributed antenna system is provided that includes a remote antenna unit that communicates with wireless devices in a coverage area, additional remote antenna units that communicate with wireless devices in additional coverage areas, and a unit that communicates with the remote antenna unit and the additional remote antenna units. The unit includes a distributed antenna system controller. The distributed antenna system controller can determine that an undesirable signal component having a power level exceeding a threshold power is communicated via an uplink path from the remote antenna unit. The distributed antenna system controller can also minimize an impact of the undesirable signal component on the additional coverage areas of the additional remote antenna units. Minimizing the impact can include modifying the gain of the uplink path over which the undesirable signal component is communicated.
