Abstract

A tag responds to receipt of a short-range wireless signal by altering the operation of a transmitter that transmits long-range wireless signals containing a unique tag identification, and conforming to a satellite or cellular network communication protocol. According to a different aspect, a tag responds to receipt of a short-range wireless signal by altering operation of a receiver that receives long-range wireless signals containing positioning information, the tag determining location information from the positioning information. According to another aspect, a tag responds to receipt of a short-range wireless signal by altering operation of a sensor section having a sensor responsive to a condition.

and

wherein said responding includes switching said transmitter section from one of said first and second operational modes to the other thereof.

15. A method according to claim 13, wherein said altering of the operation of said transmitter section includes one of:

altering a rate at which said first signals are transmitted;

altering a data format used for data transmitted in said first signals; and

altering a type of data transmitted in said first signals.

16. A method according to claim 13, wherein said transmitting is carried out in a manner that includes configuring said first signals to conform to said satellite communication protocol.

17. A method according to claim 13, wherein said transmitting is carried out in a manner that includes configuring said first signals to include a location portion containing information relating to a current location of said tag.

18. A method according to claim 17, including determining said location information as a function of positioning information from long-range wireless third signals received through a further receiver section of said tag.
