Abstract

1. Introduction Wireless LANs [1] are an easy to install alternative to wired LAN solutions. Connection to the LAN is done by a WLAN Card connecting wirelessly to one or more access points (APs, antennas). These antennas have to be placed in such a way, that any location inside, e.g. the companies buildings, is able to give access to at least one AP. Since the antenna signal is distributed radically there is typically also access to the APs near to borders from the outside of the buildings. This situation could cause a security problem, if the area does not belong to the company, or if it can easily be accessed by others (e.g. parking facilities for customers). Intruders can wirelessly tap in on the company's network. 2. Problem statement
