Cisco IUWNE 1.0: Wireless Frame Basics and Nonstandard Technologies

This course is included in our On-demand training solution.

Overview

While the 802.11x standard is most prevalent in today’s wireless environments, it is also important to have a working knowledge of non-802.11 wireless technologies and their impact on WLANs. Understanding the principles behind wireless frame exchange, whether 802.11x or nonstandard frames, is key to installing and troubleshooting wireless networks efficiently, and knowing the tools used to support these activities is just as important. This course provides the basics needed to understand which frames can be expected, what their role is, and what their speed will be in order to quickly detect when a portion of a dialog is failing. This course follows the end-to-end journey of the wireless frame, and also describes the impact of nonstandard wireless technologies on Wi-Fi networks.
This course maps to the 640-721, Implementing Cisco Unified Wireless Networking Essentials (IUWNE), exam objectives for describing the spread spectrum technology CSMA/CA; describing the impact of various wireless technologies such as Bluetooth, WiMAX, ZigBee, and cordless telephones on WLANs; describing networking technologies used in wireless, such as trunking interfaces and 802.1q trunking; and describing the management, control, and data frame types.

Target Audience

Network associates, WLAN designers, planners, implementers, optimizers, trainers or support personnel; candidates for the Implementing Cisco Unified Wireless Networking Essentials v1.0 640-721 examination, seeking to attain Cisco’s CCNA-WIRELESS credential

Prerequisites

Certification in Interconnecting Cisco Networking Devices Part 1 (ICND1/CCENT); knowledge and skills commensurate with Interconnecting Cisco Networking Devices Part 2 (ICND2); a working knowledge of the Windows operating system and Cisco IOS networking and concepts

Expected Duration

120 min.
