Systems, methods, and computer-readable media for detecting cell site component faults are provided. An unmanned aerial vehicle may be utilized to collect heat signature information about remotely located cell towers. The heat signature information is analyzed to detect any anomalies at the remote cell site that may indicate an antenna, radio, or cable connector are malfunctioning or need repair, for example. When an anomaly is detected, an indication of the anomaly and information to identify one or more components that correspond to the anomaly are communicated.
