This read-only object, in KHz, reports the specific frequency at which the subscriber unit's receive power reading was taken. It exists to give context to the paired p2mpSuMeasuredPower value, since a power reading is only meaningful alongside the frequency it was measured at. For example, an admin investigating a weak-signal complaint would read p2mpSuCenterFrequency together with p2mpSuMeasuredPower to confirm the measurement was taken on the subscriber's actual assigned operating frequency.
