radio rf-meas-interval ambient

radio rf-meas-interval ambient

To set the measurement interval of the ambient noise for performing noise floor statistics (NFS) functions, use the radio rf-meas-interval ambient interface configuration command. The NFS functions allow the user to determine the noise floor of the radio link and make adjustments to the system, (for example, adjust the target receive-power level of the upstream port). To set the interval to the default value, use the no form of this command.
