List of SC 6 Percentage for Monitoring Locations
Frequency Band Based (Per Frequency Channel)

The following maximum and mean Safety Code 6 percentages have very little probability of actually occurring. These figures are based on the assumption that all active transmitters seen by the receiver during the monitoring period are fully operational and have a 100% duty cycle. The maximum and mean columns represent the sum of the squares of the normalized electric field intensity of each measured frequency channel. For the maximum column, the normalized field intensity is based on the highest measured signal level obtained for each active frequency channel within the measurement period. The normalized field intensity for the mean column is simply the mean average of all the recorded signal levels per active frequency channel.

List of SC 6 Percentage for Monitoring Locations
Frequency Band Based (Per Frequency Sub-Band)

The following maximum and mean SC 6 percentages reflect the true radio frequency environment at the time the measurements were conducted. The maximum and mean columns represent the sum of the squares of the normalized field intensity values of each sub-band, per sweep. A sub-band is defined as a frequency span between selected start and stop frequencies. Each span contains many frequencies, up to 20,000 channels. For the maximum column, the normalized field intensity is based on the highest measured level per sub-band. The normalized field intensity for the mean column is simply the mean average of the sub-band's measured signal level. If the length of the monitoring period were extended, the number of sub-band readings would increase resulting in a more accurate representation of the radio frequency environment.
