Wireless applications 3 Some common applications of wireless data communication include the following: Accessing the Internet using a cellular phone Home or business Internet connection over satellite Beaming data between two handheld computing devices Wireless keyboard and mouse for the PC ly/169686

WLAN 4 Another common application of wireless data communication is the wireless LAN (WLAN), which is built in accordance with Institute of Electrical and Electronic Engineers (IEEE) standards.. ly/169686

WLAN transmission medium 5 WLANs typically use: Radio waves (for example, 902 MHz), Microwaves (for example, 2.4 GHz), Infrared (IR) waves (for example, 820 nm) for communication. ly/169686

WLAN modes 6 Infrastructure mode Ad hoc mode operation or-wi-fi

Infrastructure mode 7 In which wireless clients are connected to an access point via a wireless link operation or-wi-fi

Infrastructure mode 8 It is possible to link several access point together using a connection called a distribution system The distribution system can also be a wired network, a cable between two access points or even a wireless network operation or-wi-fi

Infrastructure mode 9 The closer an access point is, the higher its data transfer capacity is So, a station within range of multiple access points may choose the access point offering the balance of capacity and current traffic load operation or-wi-fi

Ad hoc mode 10 In ad hoc mode, wireless client machines connect to one another in order to form a peer-to-peer network A network in which every machine acts as both a client and an access point at the same time. operation or-wi-fi

WLAN design consideration 11 The following factors should be considered when designing wireless access layer:  Client device power  Radio frequency (RF) vulnerabilities  Volume of network traffic Controller-Based Wireless LAN Fundamentals: An end-to-end reference guide to design, deploy, manage, and secure wireless networks 1st Edition

Continuous Availability and Outage Planning 12 The factors that affect availability and for which the design considerations should be made to make the wireless deployment resilient include the following: Power loss RF interference Controller-Based Wireless LAN Fundamentals: An end-to-end reference guide to design, deploy, manage, and secure wireless networks 1st Edition

WLAN capacity 13 It can be increased by: increasing the number of cells making the cell size smaller, which means fewer users per cell sharing the media Utilizing more channels which requires managing the RF spectrum Controller-Based Wireless LAN Fundamentals: An end-to-end reference guide to design, deploy, manage, and secure wireless networks 1st Edition
