Abstract

PURPOSE:To minimize the area of an electric wave protruding from a private branch and to arrange an efficient transmitter by arranging plural transmitters for radio calling in the private branch. CONSTITUTION:A service area when four transmitters for radio calling are used in which the range of an electric wave is 'A', becomes the square where one side is 2X2<1/2>XA, as shown in the slanting line part of a figure, when the private branch is limited to a rectangle. Thus, in the rectangle or rectangular parallelopiped private branch, the range where the electric wave reaches becomes efficient.
