Course Overview:

WiFi Technology Training In Depth Course

This three-day WiFi Technology Training In Depth course offers in-depth coverage of the principles and operation of IEEE 802.11 (“WiFi”) short-range wireless communications. We will begin by looking at the indoor propagation characteristics and how to estimate range limits. You will review the government regulations and learn the techniques used by 802.11 to meet those regulations. You will then examine and compare the modulation schemes employed by the various forms of 802.11. Next, you will study in depth the operation of 802.11a, 802.11b, and 802.11g along with the IEEE 802.11n proposals to enhance throughput. We will undertake a detailed analysis of how security is implemented, followed by a look at countermeasures to various attack strategies. We will conclude the WiFi Technology Training In Depth course by discussing the coexistence of 802.11 and other wireless networks such as Bluetooth and a study of the interference solutions.

Customize It:

• If you are familiar with some aspects of this WiFi Technology Training In Depth course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the WiFi Technology Training In Depth course in manner understandable to lay audiences.
