Course Name:		WIFI Training Fundamentals
Deployment Options:		Onsite - Instructor-Led Training
Course Duration:		2-3 days depending on audience background and options

Introduction:

Driven by the use of unlicensed spectrum, WiFi has become a pervasive technology used in both business and home environments. With average selling prices of access points dropping along with WiFi enabled laptops and other devices, WiFi technology will continue to be a dominant technology in both information technology as well as telecommunications networks.

Audience:

RF Engineers, network designers, network planners, application developers, software engineers, IT personnel, IT network management, marketing personnel and executives responsible for strategy and investment who are focused on delivering and enhancing the quality of experience of subscribers with data services and applications. We offer distinct versions of this course tailored to audiences such as: Chipset manufacturers R&D personnel Systems engineers Transport engineers Less technical audiences such as managers, executives, business planners, sales and marketing specialists, and operations and support personnel.

Prerequisites:

You should have some familiarity with communications engineering. If you have an understanding of the architecture of a mobile communications network and the limitations imposed by its air interface, that will be helpful but it’s not required.

Customize it:

This 2-3-day WIFI course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.

Objectives:

The objective of the course is to familiarize students with the various standards associated with WiFi technology, uses, deployment and optimization principles to get the best performance and coverage for each application type
