1. A system, comprising:

  • a plurality of access points (APs) disposed at a site, the plurality of APs configured to associate to client devices;

    a sensor AP configured to transmit first test signals to the plurality of APs; and

    a controller configured to;

    determine, at a first time period, baselines for the sensor AP at a first AP of the plurality of APs and at a second AP of the plurality of APs that received the first test signals,instruct the sensor AP to transmit second test signals to the plurality of APs at a second time period after the first time period, wherein the second test signals are received at the first and second APs, andupon determining that a characteristic of the second test signals is substantially the same as the baseline corresponding to the first AP but is substantially different from the baseline corresponding to the second AP, determine a change in physical topology that affects a radio frequency (RF) environment at the site.
