1. A wireless communication system, comprising:
- a transponder configured to be positioned on a vehicle tire;
an interrogator; and
a control system configured to;
determine a circumferential location of the transponder on the vehicle tire;
interrogate, through the interrogator, the transponder in a window when the transponder moves in an arc proximate the interrogator; and
not interrogate the transponder when the transponder is expected to be outside the window.

Abstract
A tire sensor that communicates to a remote interrogator in one of two modes depending on the nature of the interrogation. The interrogator may be distributed throughout a vehicle if needed for design options. Further, the interrogator only interrogates the transponder when the interrogator has reason to believe that the transponder is in range of the interrogator. The interrogator and transponder may be configured to operate in different modes for communication during operation of the tire on a vehicle and during non-operation. The transponder may communicate tire condition information to the interrogator concerning environmental or other information sensed about the tire.

20. A wireless communication system, comprising:
-
a transponder configured to be positioned on a wheel; an interrogator; and a control system configured to; determine a circumferential location of the transponder on the wheel; interrogate, through the interrogator, the transponder when the transponder is determined to be within an electromagnetic field of the interrogator; and not interrogate the transponder when the transponder is expected to be outside the electromagnetic field of the interrogator. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of interrogating a transponder, mounted on a wheel, using an interrogator, comprising:
-
determining a circumferential location of the transponder on the wheel; interrogating the transponder when the transponder is determined to be within an electromagnetic field of the interrogator; and not interrogating the transponder when the transponder is determined to be outside the electromagnetic field of the interrogator. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
