The interest in WLANs (Wireless LANs) is growing strongly. The advantages of wireless communication are obvious. After the publication of the 802.11b Standard at the end of 1999, additional standards were defined which further increased the speed of data transmission. In this specialist course the participants learn in a first step the technical aspects, relevant standards and possibilities of application of the WLANs. However, the emphasis is on the safety aspects of this fascinating technology. The participants are familiarized with the safety problems of the WLANs. They are taught details of the necessary defence measures. After attending the course, they are able to utilize Wireless LANs more safely and efficiently.
