An area designing method for a mobile communication system, comprising steps
of:
placing a plurality of communicating mobile stations corresponding to traffic distribution
information; deciding a base station to which each of the mobile stations is radio
linked; calculating a transmission power of a desired wave signal that each base
station transmits to each of the mobile stations that are radio linked thereto;
successively selecting one from a plurality of evaluation positions in a state
that each of the base stations is transmitting the desired wave signals; and calculating
a reception power of a desired wave signal that an evaluation mobile station placed
at each selected evaluation position receives from the base station that is radio
linked thereto and reception powers of interference wave signals that the evaluation
mobile station receives from the base station that is radio linked thereto and
from each of the other base stations.
