Satyapada Das Department of Comp Sc. & ITINTRODUCTION: INTRODUCTION Wi-Fi is short of wireless fidelity and is meant to be used mostly when referring to any type of 802.11 network. The term is promoted by the Wi-Fi Alliance. Wi-Fi denotes a set of Wireless LAN standards developed by working group of 11 of the IEEE LAN/MAN standards committee.Slide 4: One wireless router can allow multiple devices to connect to the Internet.USES:: USES: A Wi-Fi enabled device such as PC, cell phone can connect to Internet when within the range of a wireless network connected to the Internet. Wi-Fi allows connectivity in peer-to-peer mode, which enables devices to connect directly with each other. Mobile computer can connect to Internet from any Wi-Fi hotspot, and digital cameras can transfer images wirelessly.APPLICATIONS: : APPLICATIONS: Following are major types of applications are available. They are; Mobile Security I-Phone Location TrackingMOBILE SECURITY- : MOBILE SECURITY- Now a days most of the mobiles provides facility for accessing Internet through Wi-Fi network. Each customer has a unique number and password and requests a token to the network for accessing Internet and after receiving the token through SMS he gains access to Internet. Since all data is encoded by a WEP session key, unique to each user, allowing high level of security and guest.iPHONE- : iPHONE- This iPhone native application enables Wi-Fi song sharing i.e. iPhone allows you to share music with any other iPhone or computer on the network via wi-fi. Picture is in next pageSlide 10: Wireless sharing of a music collection between two i-Phones on the same wi-fi network.Slide 11: LOCATION TRACKING Wi-Fi is increasingly being used in location tracking application. Wi-Fi tags are utilized in Wi-Fi Real-Time Location Systems (RLTS) that utilize Wi-Fi access points to locate devices with external Wi-Fi tags or devices with embedded Wi-FiADVANTAGES:: ADVANTAGES: Wi-Fi allows LANs to be deployed without cabling for client devices, typically reducing the costs of network deployment and expansion. Unlike packet radio systems, Wi-Fi use unlicensed radio spectrum and does not require regulatory approval for individual deployer. Wi-Fi networks supports roaming, in which a mobile client station can such as laptop computer can move from one access point to another as the user moves around a building or area. Cont…..Slide 13: DISADVANTAGES: To turn security on requires the user to configure the device, usually via a software GUI. Wi-Fi networks that are open can be monitored and used to read and copy data transmitted over the network if proper security is not present. Sometimes it contributes to congestion on certain channels because many access points default to the same channel on initial startup.Slide 14: Wi-Fi networks have limited range. A typical Wi-Fi home router with a stock antenna might have a range of 45m indoors and 90m outside. Wi-Fi also causes pollution that means many access points in the area on the same or neighboring channel can prevent access and interfere with the use of other access points by other, caused by overlapping of channels with decreased SNR between access pointsSlide 15: Wi-Fi uses both single carrier direct-sequence spread spectrum radio technology and multi-carrier OFDM (Orthogonal Frequency Division Multiplexing) radio technology. These regulations then enabled the development of Wi-Fi, its onetime competitor Home RF, and Bluetooth. CONCLUSIONThank You: Thank You You do not have the permission to view this presentation.
