WIFI POSITIONING BENCH TEST METHOD AND INSTRUMENT

摘要

The present invention relates to simulation on a lab workbench of conditions that would be encountered by a mobile device during a so-called drive test, which involves transporting the mobile device along a course so that it encounters fading and changing wireless access points used normally to connect the mobile device to a wireless network but in this case used to locate the device. The instrument and method also support parametric testing of transceivers used for WiFi positioning and, optionally, GNSS positioning by the same mobile device used for WiFi positioning.

主权项

1. A method of testing WiFi location circuitry and software of a mobile device under test (DUT), the method including:
coupling a test device in communication with the DUT; generating and mixing signals that emulate at least ten WiFi access points (APs) visible from a simulated DUT location at test times during a test; wherein the emulated signal from each AP is characterized by at least a unique access point address, an access point identifier, a channel number, and signal strength that are reproducible by a test time reference; sending the mixed signals from the test device to the DUT.
