Wireless LANs have established themselves as a supplement to wired LANs in corporate networks long since. In local networks and at hotspots they even replace the Ethernet to a large extent, and an end of the WLAN boom is not yet in sight. The course at hand gives an introduction to WLAN technology and WLAN application. The participants get to know the different WAN technologies and standards. The course enables them to understand WLAN architecture and to solve planning and dimensioning tasks. Hands-on exercises at the test network provide the reference to practical application.

Classroom training
- Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!
-
Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.
