Abstract
A system and method for signal backup of active DAS master unit are disclosed. The system includes a state detection unit, a backup processing unit and at least two power distribution units, wherein a backup signal output port and a plurality of backup access ports with a number great than or equal to that of the power distribution units are arranged on the backup processing unit, and a backup signal input port and a plurality of radio frequency access ports with a number great than or equal to that of the power distribution units are arranged on the state detection unit; and each power distribution unit has an input port coupled to one of a plurality of signal sources, and two output ports in which one is coupled to one radio frequency access port and the other is coupled to one backup access port, and the backup signal output port is coupled to the backup signal input port. The backup processing unit is configured to control a signal from the signal source coupled to the radio frequency access port which is in an accessing-abnormal state to access the backup signal input port, when any one of the plurality of radio frequency access ports is in the accessing-abnormal state. It can…
