Distances from antenna
For ODU deployments, Table 211 specifies calculated minimum separation distances for a
range of frequency bands and antenna sizes at the peak of the antenna beam. For IRFU
deployments, refer to Table 212. At these and greater distances, the power density from
the RF field is not considered to be hazardous. These tables are based on the worst case
transmit power.
