Wi - Fi means Wirless Fidelity It also called WLAN (Wirless Local Area Network) Wi-fi allows you to connect to the net at Broadband speeds without cables To understand the technology behind wi-fi, imagine using a walkie-talkie. Your voice is picked up by a microphone, encoded onto a radio frequency and transmitted with the antenna to another walkie-talkie, which decodes your voice. Wi-fi works in broadly in the same way, but using a better radio that is capable of handling a lot more data per second Requirement of Wi-Fi Internet : 3 Requirement of Wi-Fi Internet A wireless network connected to the Internet requires the following components: A broadband Internet connection, A modem (PCI card / Hardware), A router, A wireless access point (Hot Spots), 1. A broadband Internet connection : 4 1. A broadband Internet connection You can buy Broadband connection from any Wi – Fi service provider Wi – Fi Alliance , Netopia , Google & Adhock are some Big provider all over the world. Its price prefers on connection’s speed Many provider also give free connection in particular area 2. Modem (PCI card / Hardware) : 5 2. Modem (PCI card / Hardware) Modem is necessary for any Internet connection But in Wi – Fi Internet connection we use the word “PCI card” Now in day’s many Laptops have inbuilt hardware (PCI card) It receives and transmits signals from/to a wireless network. Slide 6: 6 If any laptop or Desktop has no Inbuilt hardware. Then you can buy it. There is deferent types of PCI card 802.11n is latest hardware for it. It’s Created by COMPAC compac 802.11n PCI card Slide 7: 7 It’s Minimum data transfer rate is 200MB/S and Maximum is 540MB/S Its operation Frequency is 2.4 GHz to 5.0 GHz It’s Minimum range for connectivity is 50 meters & Maximum is 125 meters 3. Router : 8 3. Router Router is necessary to set the area for Wi –Fi Internet It’s also used to set Wi – Fi LAN in particular Building or Schools , Collages A router becomes an access point that Transmits Wired internet through Radio waves Router : 9 Router Router is setup by Wi – Fi internet provider Router is allows connections in Laptop , Desktop & PDA mobile in range of 200 meters Wireless Router Slide 10: 10 4. Wireless access point (Hot Spots) : 11 4. Wireless access point (Hot Spots) Wireless access point is also known as “Hot Spots” A wireless access point connects a group of wireless devices to an adjacent wireless LAN Hot Spots is nothing just area covered by Router To use wi – fi internet in your device ,it must been in Hot spots location Free Public Wi – Fi Hot Spots : 12 Free Public Wi – Fi Hot Spots Many cities and towns are now offering Free Wi - Fi in their public Libraries - no purchase required or expected Many academic institutions that offer Free Wi - Fi on their campuses for Access members of their academic community - students, staff, etc. - and require some kind of login procedure to control access Hotels, Motels and Resorts offer Free Wi - Fi in their guest rooms How Hot Spots work ? : 13 How Hot Spots work ? Own Hot Spots : 14 Own Hot Spots If you are out of rich of Hot Spots , You can use your own Hot Spots It contains A Router , Solar panel , Power adapter cable and fuse holder , Charge controller By this you never loose your connection. Slide 15: 15 Wi - fi uses antennas around which wi - fi "hotspots" are created. The hotspots are outlets equipped to receive the radio waves that power wireless networking where a series of antennas are installed in the streets, on lampposts The source internet connection is provided by a PC or server to which the antennas are connected Some mobile phones and PDA now have wi – f i chips installed Many laptops and handheld computers now come with built-in wi - fi connectivity; it is also possible to add wi-fi to your computer Wi – Fi @ Gaming : 16 Wi – Fi @ Gaming Nintendo is getting behind their Wi-Fi Connection service in a big way The Wi – F i USB Connector allows with any computer to connect a broadband connection to log in to Nintendo’s Wi - Fi gaming service there is no need to pay for a wireless router and configure a wireless network where are Wi-Fi Internet used in U.S.A (shown shaded) : 17 where are Wi-Fi Internet used in U.S.A (shown shaded) Advantages of Wi - Fi : 18 Advantages of Wi - Fi Best for laptop users. Allows LANs to be deployed without cabling, typically reducing the costs of network deployment and expansion. Wi-Fi chipset pricing continues to come down, making Wi-Fi a very economical Wi-Fi is a global set of standards. Like cellular carriers, the same Wi-Fi client works in different countries around the world Widely available in more than 250,000 public hot spots and millions of homes and corporate and university campuses worldwide Not easily crackable if strong passwords are used New protocols for Quality of Service (WMM) and power saving mechanisms (WMM Power Save) make Wi-Fi even more suitable for latency-sensitive applications (such as voice and video) and small form-factor devices Disadvantages of Wi - Fi : 19 Disadvantages of Wi - Fi Security requires additional steps, without which you are vulnerable to hackers Wi-Fi networks have limited range. A typical Wi-Fi home router using 802.11b or 802.11g with a stock antenna might have a range of 45 m (150 ft) indoors and 90 m (300 ft) outdoors. Spectrum assignments and operational limitations are not consistent worldwide Wi-Fi pollution, meaning interference of a closed or encrypted access point with other open access points in the area , especially on the same or neighboring channel Everyone (especially your neighbours)can use free Wi – Fi by putting your PCI card’s antenna near your neighbour’s router who subscribed for it. Wi-Fi networks can be monitored and used to read and copy data (including personal information) transmitted over the network you have to suffer sometimes experience interference (thick walls, large metal objects, etc.) or a dropped connection.
