Definitive WiFi for engineers  |    A 5 day   hands on   training course

WiFi for engineers training course description

A hands-on course focusing on the technical support of WiFi. Wireless LANs are often seen as simple communications that are simply installed and then left alone to work. This course ensures that delegates will be able to install WiFi networks which work but also enable the delegates to troubleshoot WiFi when it does go wrong

What will you learn
  • Compare 802.11 standards.
  • Configure WiFi networks.
  • Troubleshoot WiFi networks using spectrum analysers, Wireshark and other tools.
  • Implement 802.11 security.
  • Perform RF surveys.
