ÐвтобуÑные туры .The present invention relates to an installation of a secure electronic article surveillance system or an anti-theft device and more particularly to a communication system between the inside and the outside of a protected enclosure using an opening capable of being closed off in which a transmitter and a receiver are disposed. The invention concerns a communication system between the inside and the outside of a protected enclosure, in particular to secure electronic article surveillance (EAS) or anti-theft devices or a combination of these two types of systems using a wireless communication system having low probability of interception. At present, both secure EAS and anti-theft systems such as Radio Frequency Identification (RFID) technology are used in many commercial and industrial places. In connection with a secure EAS installation, it is vital that the inside and the outside of the protected enclosure are completely and reliably separated from each other. It is also of the utmost importance that the transmitter be completely independent of the receiver because of the possibility of transmission security compromises as a result of unauthorized channel access. Accordingly, previously known wireless EAS systems in which the transmitter is an active transponder or a passive transponder have, in the known systems, an open-circuit switching between the transmitter and the receiver. However, if a previously known wireless EAS system is installed in an enclosure, communication between the inside and the outside of this enclosure is not secure and is, therefore, vulnerable to compromise. For this reason, the previously known wireless EAS system cannot be fully applied in a protected enclosure. The previously known wireless systems have many drawbacks. These drawbacks include the following: 1) In the previously known wireless EAS systems, it is necessary to couple each transmitter with a receiver. For this purpose, the transmitter and the receiver are separated from each other so that they are independent from each other. Therefore, the receiver must have at least as many antenna elements as the transmitter. In other words, the receiver is as large as or more than the transmitter. 2 32/34/34 . Disk/DVD. 5372 \\... .
