Data on the occupancy and use of the license-exempt wireless-radio bands collected over a 10 year period is summarized. Numerous examples of measured results are presented in a time-history format. The time- and frequency-varying properties of radio noise and radio interference are visually portrayed where the noise and interference is usually highly impulsive and highly changeable. Of primary concern is that the interference could not be effectively described in standard statistical terms such as peak power, average power, root-mean-square power, amplitude probability plots, or other such conventional measures. The noise and interference was nonstationary in nature with time and frequency variations comparable to message lengths.
