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.
