The Wireless LAN administration training offers network professional a complete basis in view of the 802.11 (a/b/g), 802.11e and 802.11n standard, to enter and penetrate the Wireless network industry. Starting with the RF theory, going into installation and configuration up to troubleshooting and a site survey the course conveys a training from which not only administrators profit, but all working with the Wireless LAN technology.

Target group

The course is desigened for administators as well as network professional, who want to get a solid understanding of Wireless networks and complete their knowlege of all wired networks.

The course is the ideal preparation for the Wireless LAN Certified Administraion and Wireless LAN Certified Expert exams (WLAN-CAD / WLAN-CEP).
