PatchAssist is able to identify patch field allocations in real time. This is essential in order to document network and cable structures comprehensively and failure-free. RFID technology constitutes the core of the system. Each connector is fitted with an RFID tag bearing a unique number which allows to identify each patch cable and its position in a patch field. Each port has its own tag reader which detects plugged connections immediately and signals the unique cable identification number of the identified connector to the system server.
