WIFI Technology, Applications, Design and Deployment Training

Introduction:

WIFI Technology, Applications, Design and Deployment Training Course In Depth

In this WIFI Technology, Applications, Design and Deployment Training 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. In this WIFI Technology, Applications, Design and Deployment Training course 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.

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.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
