Abstract :
Most approaches using time delay for user positioning in WLAN system have to modify the existing WLAN infrastructure. These modifications are on hardware up to the changes in protocol of WLAN. As a result, they are unattractive to use time delay for positioning system in comparing with using signal strength. This paper presents a new technique to locate the position of WLAN user by time delay measured on existing WLAN infrastructure. The advantage of proposed technique is no extra cost necessarily added in the system. The results confirm the validation of proposed technique.
