Wireless device tracking system
First Claim
1. A method of tracking a wireless device comprising a wireless interface, the method comprising:
- locating a first access point providing a threshold signal strength;
sending an association request to the first access point;
recording a network address for the first access point;
suspending normal operation of the wireless device for a length of time;
resuming operation of the wireless device periodically to determine whether the access point still provides the threshold signal strength; and
if it is determined that the first access point no longer provides the threshold signal strength and a second access point provides the threshold signal strength, sending a subsequent association signal to the second access point;
receiving the network address of the second access point, recording a network address of the second access point, and suspending normal operation.

Abstract
A method of tracking a wireless device comprising a wireless interface, the method comprises locating a first access point providing a threshold signal strength; sending an association request to the first access point; recording a network address for the first access point; suspending normal operation of the wireless device for a length of time; resuming operation of the wireless device periodically to determine whether the access point still provides the threshold signal strength; and if it is determined that the first access point no longer provides the threshold signal strength and a second access point provides the threshold signal strength, sending a subsequent association signal to the second access point; receiving the network address of the second access point, recording a network address of the second access point, and suspending normal operation.

15. An information handling system, comprising:
a processor configured for;
locating a first access point providing a threshold signal strength;
sending an association request to the first access point;
recording a network address for the first access point;
suspending normal operation of the wireless device for a length of time;
resuming operation of the wireless device periodically to determine whether the access point still provides the threshold signal strength; and
if it is determined that the first access point no longer provides the threshold signal strength and a second access point provides the threshold signal strength, sending a subsequent association signal to the second access point;
receiving the network address of the second access point, recording a network address of the second access point, and suspending normal operation; and
a memory for storing the network addresses of each access point with which the wireless device is associated; and
a wireless interface for communicating with each access point.

16. A computer readable medium comprising program instructions for locating a first access point providing a threshold signal strength, the program instructions including instructions for:
-
sending an association request to the first access point;
recording a network address for the first access point;
suspending normal operation of the wireless device for a length of time;
resuming operation of the wireless device periodically to determine whether the access point still provides the threshold signal strength; and
if it is determined that the first access point no longer provides the threshold signal strength and a second access point provides the threshold signal strength, sending a subsequent association signal to the second access point; and
receiving the network address of the second access point, recording a network address of the second access point, and suspending normal operation.
