What Is WiFi Wireless Fidelity?

The Wireless Fidelity invented by international organization with the aim of analyzing the socializing and cheap. Wi-Fi was planned interrelated to 802.11 standards, which by the IEEE and create the beginning of wireless building. The wireless communication defines numerous ways to build a connection between the transmitter and the receiver, such as DSSS, FHSS, IR - Infrared and OFDM. In 1997, the Institute of Electrical and Electronics Engineers 802.11, carried higher capacities and world famous Cisco Systems or 3COM interested in this technology. Wi-Fi is free, so you can connect to the Internet from anywhere like home, office or a public place without wire. Through Wi-Fi hotspot, you can use Wi-Fi in home business because it is in the management very easy. A Wi-Fi hotspot is a location where wireless technology for use with clients. The standard devices such as PCI, Mini PCI, USB, Cardbus and PC card, ExpressCard makes it more convenient. Odometer as Ermanno Pietrosemoli EsLaRed and Venezuela used distance of purposes to reduce.

System corresponds to every other node in the Corporate Internet. Wifi router enables access to the internet including Ethernet, switch, PCI card, hub, and DHCP.
 

Use for window KNSGEM II, NetStumbler, OmniPeek, Stumbverter, WiFi Hopper, APTools, and if you're a Unix user, then Aircrack, Aircrack-PTW, AirSnort, cowpatty, Karma etc can used.For users Mac MacStumble be KisMAC, Kismet are best .With the association of wifi tools your window become more useful.

How do we know depend use Wi-Fi wireless networking, a safe and consistent connectivity with 2.4GHz and 5 GHz frequency band has on the hardware, such as wireless Ethernet protocol and CSMA and CA facilitates path sharing. There are different spectrum used in Wifi as FHSS and DSSS and various standard operating WiFi such as 802.11b, the most popular technology used by wireless network and operates 2:40 GHz - 2.4835 GHz band Bluetooth strategy, cellular phones to use and scientific equipment, has 802.11 5.725 GHz to 5.850 GHz range and provide up to 54 mbps speed, 802.11g cover three non-overlapping channels and allow PBCC provide 802.11e sufficient quality and offer video, audio, voice channel etc. you can connect WiFi via adapter card and you have to know about SSID, infrastructure, and data encryption. Security protects your privacy by. MAC ID filtering, Static IP addressing, and WEP encryption.
