Position detection of wireless terminal tends to be important technology in wireless communication system. Demand for position detection is increasing. This paper proposes position detection method using bi-directional LCX (Leaky CoaXial cable). Due to bi-directional and the reflection at end of LCX on purpose, proposed method makes four propagation pathes. Proposed system can detect two dimensional position using the differences of four propagation times. This paper describes the equations for position detection and optimal arrangement about slots.
