This 2 day course is designed to teach students solid, basic network management skills using a network analyzer. This class also provides a logical troubleshooting approach to capturing and analyzing wireless 802.11 data frames. With this knowledge, students can effectively troubleshoot, maintain, optimize and monitor their 802.11 wireless network traffic.

Objective:

Learn to use a network analyzer to discover where problems exist and implement solutions. Be familiar with and understand 802.11 Wireless Ethernet specifications, principles, and physical layer components. Be able to recognize differences between problems in the network and problems in upper-layer processes. Determine a solid approach for troubleshooting by understanding the concepts that define the 802.11 Wireless Ethernet environment. Plenty of hands on analysis to aid in the learning process.
