About this course

Course code TPWR1401
Duration 1 Day

This course presents an overview of the 802.11 family of wireless LAN technologies that are more commonly known as WiFi.

The course introduces the various forms of WiFi currently in use and looks in detail at the structure, operation and functionality of WiFi connections. It then examines issues related to the integration of WiFi access into cellular providers portfolios and techniques that allow interworking between the access environments.
