Abstract :
Positioning systems using PHS are used in the field of logistics since the system is easily installed for users and can position a PHS terminal attached to a transport object in a building, and the terminal needs little electricity to work . In this study the methods of increasing the accuracy of the PHS positioning system and extending the battery life of the PHS terminal used in the system were developed and evaluated.
