Course Name:	Wireless LAN Training Fundamentals
Deployment Options:	Onsite - Instructor-Led Training
Course Duration:	3-4 days depending on audience background and options.

Introduction:

This course provides an understanding of the Wireless LAN technologies, applications and standards. Other important topics such as protocol layers, quality of service, throughput, coverage, interoperability, interference and security are discussed. Basic RF theory, propagation, Link budget math, Troubleshooting, WLAN Security foundations and site survey are explored. After a general introduction to wireless networks, this practical course moves quickly into the details of the Wireless LANs standards (802.11a, 802.11b, 802.11g), 802.11 physical (DSSS and OFDM), dMAC (Media Access Control), detailed 802.11 framing, WEP (Wired Equivalent Privacy protocol), WPA/WPA2, TKIP, 802.1x, Enhanced MAC (IEEE 802.11e), 802.11f, 802.11i, QoS Requirements, Inter-frame Spacing, EDCF Access, HCF for QBSS, Enhanced Security management operations, and the PCF (point coordination function) are all covered in detail. Real-world experiences through case studies and implementation tips located throughout the course reference material.

Audience:

Anyone who require in-depth knowledge of Wireless LANs and its connection to current and future mobile and cellular network. Anyone who needs to implement a wireless extensions to an existing LAN-Network. Design engineers, field engineers, test engineers, software and hardware engineers who need to understand 802.11 PHY and MAC layers will benefits from this program.

Customize it:

This 3-4-day 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.

Course Aim:

After successfully completing the course the students will: Understand the basic concepts of 802.11 Be able to understand the technical implementation of different types of Wireless LANs Gain a general understanding of Wireless LANs systems coverage and capacity Be able to select the most effective wireless LAN type from a wide assortment of recent and emerging standards. Examine an Independent assessment of competing wireless LAN technologies. Be able to perform a more efficient design and operational support of wireless LANs because of an understanding of wireless LAN protocol operations and frame structures.
