Wireless LAN - Hotspots and Security

Course description (english, PDF)

Duration: 2 days

WLAN takes over the leadership – especially in light of the decreasing 3G-euphoria quite a few parties are consumed by the charm of Wireless LAN and public hotspots.

This course begins with an introduction to the wireless LAN technology. The course discusses the various possibilities of the configuration as well as the physical functionality and different access methods on the transfer mode by air.

A focus of this course is on the subject of security. The participants obtain an overview of the security mechanism with WLAN and the current possibilities to protect themselves as operating companies as well as their customers against unauthorised attacks on private data.

At the end of the course we will discuss also the challenges of the billing process. Some billing solutions as well as the integrations into UMTS will be presented.

Target Group / Requirements

The course is addressed to network managers and those who are interested in obtaining a basic understanding of the WLAN technology and deal with the much discussed security aspects. Basic knowledge in the area of data networks is a prerequisite for this course.
