Overview/Description
The technology behind sending wireless signals includes antennae, which are needed to transmit RF signals, and spread spectrum technologies, which include the protocols involved in sending wireless frames. This course describes the different types of antennae used in wireless implementations. It outlines the principles behind antenna technology, and discusses how to chose the right antenna based on where and how you want the signal to be received. This course also explains spread spectrum technologies, including Direct Sequence Spread Spectrum (DSSS) and orthogonal frequency-division multiplexing (OFDM), as well as the various modulation types used with each. In addition, the issues linked to channel overlaps and channel reuse are explored. This course maps to the 640-721, Implementing Cisco Unified Wireless Networking Essentials (IUWNE), exam objectives for describing the basics of spread spectrum technology including modulation, DSSS, OFDM, channels reuse and overlap, and describing WLAN RF principles including antenna types and RF gain and loss.
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 credentials.
Prerequisites
