Abstract
This study describes a method to integrate a personal handy-phone system (PHS) positioning system, which utilizes the electric-field intensity of the base station, with an exploration method, which utilizes the directional-antenna terminal electric-field strength, to search lost items in logistics markets. This methodology employs the directional antenna to confirm the position of the lost item within the errors of the PHS positioning system. An effective exploration method is proposed by comparing the position, which is obtained from the relationship between the electric-field intensity of the PHS terminal and the distance, and the position obtained from the cross point of directions of the maximum terminal electric-field intensity measured at several positions. By focusing on Chinese logistics business background and targeting the positioning and car sharing, the quantitative utilization tendency and requirement estimation are done by using the traffic data which includes PHS positioning data, reservation data, cycle data, etc.
