SYSTEM AND METHOD FOR TESTING WIRELESS POSITION LOCATING
First Claim
1. A method for testing the position locating technology of a wireless client, the method comprising:
- selecting a test scenario for a wireless client, the test scenario comprising at least one simulated location of the wireless client and at least one wireless access point visible to the wireless client from the simulated location of the wireless client;
identifying an expected response creation time for the at least one wireless access point visible to the wireless client;
emulating the at least one wireless access point visible to the wireless client and simulating a distance between the simulated location of the wireless client and the location of the at least one wireless access point using an adjusted response creation time for the at least one wireless access point;
executing the test scenario using the expected response creation time and the adjusted response creation time for the at least one wireless access point to test the position locating technology of the wireless device.

Abstract
The present application describes a system and method for testing the position locating and navigation technology of a wireless client. To simulate the locations of the wireless access points in the array that are visible to the wireless client from the simulated location, the round-trip time between the wireless client and a wireless access point can be modified by delaying a response signal from the wireless access point in response to a signal received from the wireless client. The wireless client, knowing the location of the wireless access point and the expected response time of the wireless access point, interprets the delay in the response of the wireless access point as proportional to the distance of the wireless access point from the simulated location of the wireless client.
