ESTIMATION METHOD OF RECEIVED RADIO WAVE INTENSITY DISTRIBUTION OF WIRELESS BASE STATION AND REDESIGN METHOD OF ANTENNA

Japanese Patent JP2022113935

A

To provide a technique capable of accurately estimating a received electric field intensity distribution for grasping capability of a wireless base station.SOLUTION: An estimation method of a received radio wave intensity distribution of a wireless base station includes a first step of acquiring data on received radio wave intensity measured by a radio wave receiver mounted on a vehicle traveling within a target area, a second step of calculating a spatial propagation loss using a plurality of types of model formulas for calculating the spatial propagation loss using specification information of a target wireless base station as input information to calculate a received radio wave intensity distribution, a third step of selecting, from among the plurality of received radio wave intensity distributions calculated in the second step, a received radio wave intensity distribution whose change trend is closest to a the received radio wave intensity distribution obtained in the first step, and a fourth step of determining an estimated received radio wave intensity distribution by moving the received radio wave intensity distribution selected in the third step and matching the same with the received radio wave intensity distribution acquired in the first step.SELECTED DRAWING: Figure 3
