A Word About Wifi or Wifi Technology

Wi-fi is the other name for wireless internet or wireless network, this name is usually employed by none complex users who just is aware how to access internet wirelessly, they know fairly much nothing beyond that. WiFi is basically brief form for wireless faithfulness. However many advance users aren’t well aware of this terminology either, it is, more known with a name of Wireless. WiFi term is written in many ways which are, Wifi, WiFi, WIRELESS, Wi-Fi fiwi etc.¬†Verizon Fios Double Play for $49.99 ymmv

Wi fi was introduced by Wi fi alliance in 1985 it was the time when it was not used as commercially but were just set to certain organizations for testing purposes. Wi-Fi Alliance is leading in developing WiFi technology and all the hardware associated with Wifi is mostly certified by Wireless Alliance compliance. Wifi later developed properly and than eventually lunched for general population use in USA in 90’s, slowly but surely wifi become standards for almost all of the computer communications in many organizations surrounding the world¬†

Wi-fi uses all the sites referring to any sort of 802. 11 network standards which is set by IEEE. IEEE is short form of Institute of electric and electronic engineering. Generally there are lots of advancements made in standards of 802. 11 and 802. 11a, 802. 11b and other dual networks. The latest standard of 802. 11 family is 802. 11y. Other known specifications are 802. 16, these are the criteria for upcoming technology regarded as WiMax. There is one more known set of requirements for Ethernet it is known to be IEEE 802. 3.

Growth of Wifi networks is still on going worldwide this huge growth raises security issues. Wifi is considered the most broadly used network world vast and many organizations copy their sensitive data using Wireless networks. Increased use of Wireless network raises potentially risks of the security of the users or organization. Wireless network carries data of each type, that can be normal data in bits of information or it can encrypted or even highly sensitive. WiFi security system insures the certain level of data integrity and confidentiality just as born network provides. However if proper security measures are certainly not adopted properly intruders can attack the network and can cause major harm to not only network but privacy of users also.

There was a time when cables were used to network many pcs together. Hardware like routers, hubs, switches etc were required for communication between computers, but Wifi helped bring high tech change in communication of computers by providing wireless connectivity features. It just keeps things very simple without much hassle and networks can be made much more easily. No wires are essential. Cellular network keeps environment very neat and clean. Generally there are many other features of Wireless LANs for example broadband connectivity. Wireless provides broadband connectivity and faster communication where cabling are not possible set up for example in remote control areas. The set of the Wifi features is long some other major features included Site survey, venture grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, Consumer mobility and easy get through Hotspots.

WiFi facilitates two different types of modes; they are really known to be infrastructure and the other one is advertisement hoc. In Ad hoc Wireless connections can be made without central device called router or gain access to point. Most network facilitators prefer ad hoc over infrastructure mode. Ad hoc how ever have issues also. Wifi devices linked using Random mode offers less security against unapproved users. Random mode tweaked devices cannot disable SSID broadcast as opposed to infrastructure method, this brings hackers into play, and using advertisement hoc mode not necessarily very difficult to prevail in to the wireless network. There are two major dissimilarities between the two of these modes that is the rate when they transfer data. Wife network standard 802. 11g requires Ad hoc mode of communication to support 11Mbps bandwidth in contrast to it 54Mbps data is supported using infrastructure function. Hence Ad hoc setting is considered much reduced than Infrastructure mode.
