ABSTRACT:
A method and system for detecting whether an antenna is property connected to a distributed antenna network. The current drawn by the antenna is measured and compared against an expected current draw or reference level. The measured level of current drawn by the antenna is indicative of whether the antenna is properly connected or is disconnected. The comparison results may be used as the basis for creating a status message, which is then communicated to a central monitoring unit for each antenna. The central monitoring unit may generate appropriate alarms in response to a status message indicating a fault condition at a particular antenna.
