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 http: //www. ciscopress. com/articles/printerfriend 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) 802. 11 standards. . http: //www. ciscopress. com/articles/printerfriend 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. http: //www. ciscopress. com/articles/printerfriend ly/169686

WLAN modes 6 �Infrastructure mode �Ad hoc mode http: //ccm. net/contents/804 -wifi-modes-ofoperation-802 -11 -or-wi-fi

Infrastructure mode 7 �In which wireless clients are connected to an access point via a wireless link http: //ccm. net/contents/804 -wifi-modes-ofoperation-802 -11 -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 http: //ccm. net/contents/804 -wifi-modes-ofoperation-802 -11 -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 http: //ccm. net/contents/804 -wifi-modes-ofoperation-802 -11 -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. http: //ccm. net/contents/804 -wifi-modes-ofoperation-802 -11 -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 802. 11 wireless networks 1 st 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 802. 11 wireless networks 1 st 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 802. 11 wireless networks 1 st Edition
