Who Should Attend:

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 will benefits from the workshops.

Prerequisites:

Basic understanding of wireless is recommended.

Course Description:

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.

Course Objectives:

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.
