C63 C63.27-2021

This standard specifies methods for assessing the radio-frequency (RF) wireless coexistence of equipment that incorporates RF communications. This standard specifies key performance indicators (KPIs) that can be used to assess the ability of the equipment under test (EUT) to coexist with other equipment in its intended operational environment.

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.

Revision Standard - Active. An evaluation process and supporting test methods are provided in this standard to quantify the ability of a wireless device to coexist with other wireless services in its intended radio frequency environments.
