- Course in a Nutshell
-
Driven by the use of unlicensed spectrum, WiFi has become as pervasive a technology at home as it is at work. WiFi-enabled laptops, PDAs, and other devices continue to proliferate as the prices of access points continue to drop. Whether you are in telecommunications or information technology, WiFI will continue to be an important technology to study for some time to come.
In this course, you will learn about the market landscape of WiFi, the RF principles key to WiFi operation, how WiFi networks work, and the applications of WiFi. We will take an in-depth look at the various standards associated with this technology including 802.11a, 802.11b, 802.11g, and 802.11n. You will also study how WiFi networks are designed, deployed, and optimized. In short, you will learn everything necessary to get the best performance and coverage for your WiFi application.
- Customize It!
-
We can customize this course to the needs of specific audience groups to make the course more or less technical or to focus on the particular issues and technology aspects of interest to the audience in question. We perform most tailoring at little to no added charge.
