            6.9.1. Note: The following equation is used to determine the output power from the
                   measured worst case field strength:

                                                          (E x d) 2

                                                         (30 x G)

                         P     =   the power in Watts.
                         E     =   the measured maximum field in V/m
                         G     =   the numeric gain of the transmitting antenna over an isotropic radiator.
                         d     =   the distance in meters of the field strength measurement.
