Wireless LANs have long been a core component of every company network. In home networks and hotspots, they have almost completely replaced Ethernet, and there is no end in sight to the WLAN boom. This WLAN course provides an introduction to the technology and use of WLANs. Participants learn about the different WLAN technologies and standards, understand the architecture of WLANs and can solve planning and dimensioning tasks. Demonstrations on the test network provide the necessary practical relevance.
