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 MAC address, SSID, wireless protocol, channel number, and signal strength that are reproducible by a test time reference;

    wherein at least one emulated access point among the at least ten APs provides two-way communication access for the DUT to a network;

    sending the mixed signals from the test device to the DUT.
