Wireless communication system having a guest transmitter and a host receiver

A wireless communication system comprising:

• at least one guest having means including a guest transmitter for transmitting guest signals;
• and
• at least one host having means including a host receiver for receiving the guest signals, said host comprising means for establishing a link with the guest upon reception of a declaration signal transmitted by the guest, after which the host will respond to regular operation signals transmitted by the linked guest, characterized in that:
• the means for establishing the link with the guest establishes the link upon reception by the host of the declaration signal transmitted by the guest while the guest transmitter is located within a declaration area of the host, said declaration area being an area different from a normal operating area of the guest/host pair, and said means not establishing the link with the guest upon transmission of the declaration signal by the guest while the guest transmitter is located outside said declaration area, the difference between the declaration area and the normal operating area being set on the basis of a parameter other than transmission power level, and the guest uses substantially the same transmission power for transmitting the declaration signal and for transmitting the regular operation signals.
