*Seminari: IEEE 802.11n WLAN Technology*

Dies i hores: dimarts 17 de maig (10-12 h), dimecres 18 de maig (10-13 h)

Lloc: aula de Xarxes III-04i (P-III)

Professor: Ewald Graif, Dipl.-Ing. (FH JOANNEUM University of Applied Sciences, Graz, Austria)

Resum: This seminar provides an overview of Wireless LAN (WLAN) IEEE 802.11 technologies in use. Basic WLAN security measures are presented as well. The main aim of the seminar is to explain driving technology principles that allow higher data rates of the new IEEE 802.11n de-facto standard: modulation, MIMO technology, channel bonding and packet aggregation. A practical lab implementation will be performed by workshop participants: Setup of IEEE 802.11n access points and client devices in various configurations. Implementations are analyzed by performance measurements. Practical configuration will be performed by remote access to the network lab at FH JOANNEUM

 *Seminari: Virtual Private Networks*

 Dies i hores: dijous 19 de maig (10-14 h)

Lloc: aula de Xarxes III-04i (P-III)

Professor: Ewald Graif, Dipl.-Ing. (FH JOANNEUM University of Applied Sciences, Graz, Austria)

Resum: This seminar provides an overview of Virtual Private Networking services ensuring authenticity, integrity and confidentiality of communication. The presented theory focuses on widely used and IPv6 compatible IPsec implementations. Two practical lab implementations will be carried out by workshop participants: the first one dealing with IPsec/VPN site to site configuration and the second one with a remote user access of IPsec implementation at Cisco ASA firewalls. Configurations will be performed by accessing the remote lab at FH JOANNEUM.
