The CCNA Wireless certification covers wireless LANs, including networking associates/administrators, wireless support specialists, and WLAN project managers. The certification validates skills in the configuration, implementation, and support of wireless LANs. 200-355 WIFUND (Implementing Cisco Wireless Networking Essentials) is the required exam.
CCNA (Cisco Certified Network Associate) is an entry-level information technology (IT) certification offered by Cisco Systems.CCNA certification is widely recognized in the IT industry as the foundational step for careers in IT positions and networking roles.
These acronyms are used to discuss LAN, internet, WAN, routing and switching protocols, and their applicable organizations. [1] [2] [3] The table contains only current, common, non-proprietary initialisms that are specific to information technology. Most of these initialisms appear in IT career certification exams such as CompTIA A+.
This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [d] The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. [6] [7]
A global area network (GAN) is a network used for supporting mobile users across an arbitrary number of wireless LANs, satellite coverage areas, etc. The key challenge in mobile communications is handing off communications from one local coverage area to the next. In IEEE Project 802, this involves a succession of terrestrial wireless LANs. [68]
Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.
