Metric name: Co‐site impact.

Metric description: The ability to reduce co‐site impact on the assigned spectrum.

Metric measured property: SNIR.

Metric scale: dB.

Metric source: The DSA cognitive engines can track the SNIR from the collected spectrum sensing information and create an average for each waveform according to the waveform signal characteristics.

Note: Co‐site impact may or may not be tolerable by a given waveform. This metric can show the average time SNIR exceeded a given threshold that is considered intolerable while co‐site interference was known to exist and was accepted because of a policy or because of the limited availability of alternative spectrum bands that can be used.⁸
