Wi-Fi System Engineering (1 days or 6 hours)

Wi-Fi or more accurately IEEE 802.11 technology has become widespread over the past decade and can now be found in as diverse locations as trains and planes as well as in offices, homes, coffee shops, airports etc. This course sets out to explain how this technology operates through a combination of theory and practical exercises using protocol analysers to capture real network traces. It then discusses how the technology has been modified in order to improve security and support real time applications.

Who Should Attend

This course is designed for Technical Staff involved in the development and deployment of Wi-Fi technology or Product Managers requiring a detailed insight into the operation of a Wi-Fi network.

Pre - Learning

Pre-Learning is provided to prime those attending the instructor led phase. Each lesson is based on an interactive online format and should take about 30 minutes to complete. The pre-Learning lessons are:

  • Test of Understanding - Try the online check to see how much you know.
  • Wi-Fi Architecture.
  • Wi-Fi Operation.
