Claim 8:
9. An apparatus, comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform:
determining, for a base station that transmits on an operating frequency, whether a radiation pattern of each of one or more neighboring frequencies is correlated with a radiation pattern of the operating frequency at least by determining that a respective characteristic of the radiation pattern of each of the one or more neighboring frequencies and of the radiation pattern of the operating frequency differ by not more than a predetermined amount based on a set of correlation test criteria comprising the following for a given one of the one or more neighboring frequencies:
azimuth and elevation half-power angular ratio quantities of the radiation pattern of the given neighboring frequency match those of the operating frequency;
measured azimuth and elevation half-power beam widths of the given neighboring frequency match those that are derived from half-power beam widths of operating frequency radiation patterns; and
a product of measured azimuth and elevation half-power beam widths and directivity for the given neighboring frequency matches to a directivity-beam width product for the operating frequency; and

computing, in response to a determination that the radiation pattern of each of the one or more neighboring frequencies is correlated with that of the operating frequency, a total radiated power estimate of each of the one or more neighboring frequencies by performing a beam-based directions procedure for the base station, and outputting the total radiated power estimates of each of the one or more neighboring frequencies.
