Abstract

The usage of WLANs (wireless local area networks) for both office and non office (e.g. factory automation) applications is one of todaypsilas upcoming trends. However the usage of WLAN suffers from the problem that nowadays one cannot determine the exact position of standard compliant wireless nodes. This paper presents an approach for location based services and investigates the possibilities of the, for this sake, required high accuracy timestamping of incoming packets. A simulator model has been built for IEEE 802.11 physical layer and it has been found that high accuracy timestamping of incoming packets is possible.
