Abstract: A system (20) for establishing wireless communication between at least one medical device (2) having a predefined unique identification (ID) and at least one communication unit (4, 6, 8) includes a communication unit (4, 6, 8) provided with a primary two-way wireless data communication interface (52) including systems for wirelessly performing primary two-way data communication, including receiving and transmitting information (10, 14). The system (20) includes systems for securing that the primary two-way wireless data communication can be carried out if and only if the communication unit (4, 6, 8) positively and in advance has identified the predefined unique identification (ID) of the medical device (2). The system (20) includes secondary one-way wireless communication systems (24, 24?, 28, 30) configured for carrying out identification of the predefined unique identification (ID) of the medical device (2) through secondary wireless communication.
