2-Day Instructor Led Hands On Lab Class Available in either Web Based delivery or On-Site Delivery Minimum 10 students - Maximum 20 students

What Students are Saying about this class:

• “Just wanted to say well done, as well as thank you. As you likely deduced, our company is most definitely lacking in the wireless testing equipment department. As I'm sure the free software your class presented will prove more than helpful, I hope that the members of our management attending this class, see fit to invest in a few of the spectrum analyzers you recommended. Thanks again, and I assure you that I learned a whole lot more than I ever figured I would about the dreaded WLAN we all deal with in this industry.”
• “This is an amazing course. Learning about Interchannel interference & other devices (microwave)”
• “Very intuitive website and course structure, very interesting, keep it up!”
• “Great Instructor...is patient and works with the students to ensure everyone is on the same page of understanding. Helps those that are stuck and appreciates that there are no 'stupid' questions!”
• “Andrew was awesome. Very knowledgeable - eager to help...speaks clearly, timely, answers questions.”
• “Best Class I have ever attended – great job Andy”

Course Description:

Knowing the fundamentals of Wi-Fi/Wireless LAN Operations  is vital to anyone who is in the networking field today, whether it be Service Provider level or Enterprise level, especially considering the need to support wireless access technologies by Field Operations, Customer Service, and IT departments. This insightful and revealing course has been designed to focus on the operational aspects of implementing and maintaining a Wi-Fi/WLAN deployment, networking design, and performance measurement.  This course will help you understand how Wi-Fi/WLAN networks operate.  We will focus on 802.11 functions, and we will define terms and acronyms along the way.  We will discuss what can go wrong in Wi-Fi/WLAN networks.  In the end, the students will be able to better troubleshoot and communicate with peers and customers.

The course is a combination of knowledge training, systems analysis, with hands-on exercises using a variety of tools in a swift, comprehensive, and understandable way.

• "Where is the best place to deploy the Access Point?"
• "What must I know about WLAN deployment options that will affect the network operation?"
• "What tools exist to help me analyze and design the best WLAN implementation?"
• "How do I properly configure WLAN equipment to improve customer satisfaction?"

Course Objectives:

The objectives of the course are to develop a "hands-on" skill set targeted at Wireless technology and IP Routing in the following key areas:

• Wi-Fi/WLAN Site Survey procedures and tools
• 802.11 a/b/g/n/ac operation
• IP Addressing and Subnetting in a deployed Wi-Fi/WLAN
• Delivering Wireless Quality of Service with IP
• Be able to design/redesign Wi-Fi/WLAN Operation to mitigate performance issues
• Attain a fundamental understanding of Wi-Fi/WLAN Operations and improve customer service

These objectives are met by covering the necessary technical bases in a straight forward manner, by keep the content in context of the objectives - connecting the dots. Utilizing a short, subject specific architecture with exercises to drive home key points and Hands-On experience that reveal these points builds skills and knowledge based on Bloom's Taxonomy. The presentation is always industry current and up-to-date using a technology specialists.

Audience:

The target audience for this course is anyone in Field Operations, Customer Support, Engineering, Dev. Test, Technical Marketing, or even Sales Engineering that requires a solid and complete understanding of Wi-Fi/WLAN operations with a frame of reference as the Wireless or Wired Service Provider.
Ideal candidates are:

• Operations individuals that will provide Wi-Fi/WLAN's, configuration and support services
• Customer Support individuals that must know Wi-Fi/WLAN's that must understand problems and provide solutions
• Network Design Engineers that need to understand Wi-Fi/WLAN services and applications
• Network Management individuals that are providing element and network management tools
• Technical sales individuals that must be able to correlate features with functionality
• Technical marketing individuals that want more than just a basic understanding of Wi-Fi/WLAN's

Course Prerequisites:

This course appeals to anyone needing the skills and knowledge of Wi-Fi/WLAN's. The ideal student will have some experience in Wireless networking and operations, however no prior knowledge is necessary.

All students must attend with a lap-top computer in order to execute the Lab Exercises. If the course is held at a classroom where computers are available, the Lap-top computer will not be required.

Course Materials:

Students will be provided with a Course Student Guide.
