Wireless security system

A system comprising:

• a mobile transmitter;
• a plurality of boundary tags for receiving communications from the mobile transmitter, at least one of the plurality of boundary tags has a unique identifier;
• and
• a processor in communication with the transmitter, the processor programmed to determine if the transmitter is communicating with at least one boundary tag whose unique identifier matches at least one predetermined unique identifier.

A system comprising:

• a mobile transmitter;
• a plurality of boundary tags for receiving communications from the mobile transmitter;
• and
• a central control station for communicating with at least one of the plurality of boundary tags, the central control station comprises a receiver for receiving a reflected modulated signal from the at least one of the plurality of boundary tags.

A system comprising:

• a mobile transmitter;
• a plurality of boundary tags for receiving communications from the mobile transmitter;
• and
• a central control station for communicating with at least one of the plurality of boundary tags, the central control station comprises a transceiver for transmitting a signal to the at least one of the plurality of boundary tags and for receiving a reflected modulated signal from the at least one of the plurality of boundary tags.

A method of operating a security system having a plurality of boundary tags and a central control station, the method comprising the steps of:

• transmitting a first signal from a mobile transmitter;
• receiving the first signal using at least one boundary tag of the plurality of boundary tags;
• determining if the mobile transmitter has come into proximity of the at least one boundary tag by receiving a reflected modulated signal from the at least one boundary tag;
• providing a response when the mobile transmitter comes into proximity of the at least one boundary tag;
• and
• receiving the reflected modulated signal at the central control station.

• recording the receipt of the first signal at the at least one boundary tag;
• transmitting a second signal from the central control station to the at least one boundary tag;
• receiving the second signal at the at least one boundary tag;
• and
• receiving the reflected modulated signal at the central control station.
