 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.
Cisco Certified Network Associate Wireless (CCNA® Wireless) validates associate-level knowledge and skills to configure, implement and support of wireless LANs, specifically those networks using Cisco equipment. With a CCNA Wireless certification, network professionals can support a basic wireless network on a Cisco WLAN in a SMB to enterprise network. The CCNA Wireless curriculum includes information and practice activities to prepare them for configuring, monitoring and troubleshooting basic tasks of a Cisco WLAN in SMB and Enterprise networks.
This training 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.).
