A method of declaring Equivalent Isotropically Radiated Power (EIRP) for an operating frequency band of a base station. The method includes: declaring a first EIRP for a first frequency of the operating frequency band, declaring a second EIRP for a second frequency of the operating frequency band, and declaring a third EIRP for a third frequency of the operating frequency band, wherein the third frequency is between the first frequency and the second frequency, and wherein the second frequency is higher than the first frequency.
