Abstract
Technologies directed to antenna disconnection detection of distributed radio frequency (RF) ports in a wireless network are described. One method receives data from the wireless devices and generates an RSSI matrix including multiple elements, each storing a receive signal strength indicator (RSSI) value indicative of a signal strength of a wireless link between a transmitter-receiver pair. The method identifies a characteristic pattern in the RSSI matrix. The characteristic pattern includes i) two or more RSSI values in a same row being less than the threshold value and ii) two or more RSSI values in a same column being less than the threshold value. The method stores an indication that an antenna is disconnected from an RF port and sends a command to the second wireless device that causes the second wireless device to disable a radio that is coupled to the RF port.
