Claim Text:
1. An unfiltered device detection method, implemented by an unfiltered device detection system, comprising: initiating a first link with a first power spectral density (PSD) profile; obtaining and storing, in a memory, first signal to noise ratio (SNR) and transmit power levels based on the first link; initiating a second link with a second PSD profile different than the first PSD profile; obtaining and storing, in a memory, second SNR and transmit power levels based on the second link; and identifying, by processing circuitry, at least one unfiltered device by comparing the first SNR and transmit power levels to the second SNR and transmit power levels, wherein the comparison of the first SNR and transmit power levels to the second SNR and transmit power levels is made to determine a ratio of a noise on the first link, N where S the at least one unfiltered device is determined to be present when the value of N
