Cisco IUWNE 1.0: Wireless Fundamentals

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


Wireless network deployment has exploded in recent years. The use of wireless devices went quickly from early adoption in sites where cabling was difficult or impossible, to widespread use in home networks. The change was rapid due to the ease of use of wireless routers and other equipment. With improvements in security and performance, wireless networks have moved into many mainstream business LANs. With new and better standards and equipment in development all the time, growth is virtually unlimited. This course introduces wireless networks, examining where they are used and what kinds of wireless networks can be built. The evolution of wireless technology, wireless topology categories, and wireless networks types, such as ad hoc and infrastructure are discussed, along with some basic wireless devices. This course also explores WLAN radio frequency (RF) principles and RF mathematics, to provide an explanation of how the radio waves used in wireless networks function.
This course maps to the 640-721, Implementing Cisco Unified Wireless Networking Essentials (IUWNE), exam objectives for describing wireless topologies (IBSS, BSS, ESS, Point-to-Point, Point-to-Multipoint, basic Mesh, bridging); describing networking technologies used in wireless (SSID, WLAN_ID, Interface, VLAN, 802.1q trunking); and describing WLAN RF principles (refraction, reflection, etc.).

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


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
