Title:
APPARATUS FOR INDICATING MEASUREMENT POSITION AND METHOD FOR INDICATING MEASUREMENT POSITION
Document Type and Number:
WIPO Patent Application WO/2014/033874
Kind Code:
A1
Abstract:
Provided is a technique for properly indicating positions requiring collection of position information and of a set of radio wave intensities at these positions, used in order to generate a mathematical model representing an intensity distribution of radio waves transmitted by a radio transmission device. This apparatus for indicating a measurement position estimates a position at which a difference exists between a mathematical model representing the intensity distribution of radio waves transmitted by a radio transmission device and the true radio wave intensity distribution, and indicates that the position information and the set of radio wave intensities at this position are to be re-collected (see fig. 8).
