1.8.4 Calculated Distances and Power Compliance Margins
Table 4 shows calculated minimum separation distances d, recommended distances and
resulting power compliance margins for each frequency band and antenna combination.
These are conservative distances that include compliance margins. At these and greater
separation distances, the power density from the RF field is below generally accepted limits
for the general population.
