The purpose of this standard is to provide evaluation procedures, test methods, and other guidance for assessing the ability of the EUT to successfully maintain its functional wireless performance (FWP) (see 5.3) in the presence of unintended signals that are likely to be found in the same operating environment. This standard includes assessment of the effects of the EUT on the unintended signals. The results of this test may optionally be used to compute the likelihood of coexistence (LoC), or as an input to a risk assessment.
