A thing About Wifi or Wifi Technology
WiFi will be the other good name for wireless internet or wireless network, this name is usually used by none technical users who just is able to access internet wirelessly, they know just about nothing beyond that. WiFi is basically short form for wireless fidelity. However many advance users are not well aware of this terminology either, it is ,more known using a name of Wifi. WiFi term is written in many ways that are, Wifi, WiFi, WIFI, Wi-Fi fiwi etc.

Wi-Fi was introduced by Wi-Fi alliance in 1985 it turned out enough time in the event it had not been used as commercially but were just set to a particular organizations for testing purposes. Wi-Fi Alliance is pioneer in developing WiFi technology as well as the hardware linked to Wifi is generally certified by Wifi Alliance compliance. Wifi later developed properly and than eventually lunched for public use in USA in 90's, gradually wifi become standards for some in the computer communications in countless organizations around the world
Wifi uses each of the networks speaking about any kind of 802.11 network standards that's set by IEEE. IEEE is short type of Institute of electrical and electronic engineering. There are numerous enhancements stated in standards of 802.11 and 802.11a, 802.11b along with other dual networks. The most recent standard of 802.11 household is 802.11y. Other known standards are 802.16, fundamental essentials standards for upcoming technology considered to be WiMax. There is another known pair of standards for Ethernet it is known to be IEEE 802.3.
Development of Wifi networks remains ongoing globally this massive growth raises security issues. Wifi is the most trusted network worldwide and several organizations transfer their sensitive data using Wireless networks. Increased usage of Wireless network increases potentially risks of the protection from the users or organization. Wireless network carries data of each and every type, which can be normal data in pieces of information or it could encrypted or perhaps highly sensitive. WiFi security mechanism insures the certain amount of data integrity and confidentiality just as wired network provides. If however proper safety measures are not adopted properly intruders can attack the network and may cause major problems for not only network but privacy of users also.
The times when cables were utilised to network many computers together. Hardware like routers, hubs, switches etc were necessary for communication between computers, but Wifi brought modern day change in communication of computers by providing wireless connectivity features. It really keeps things very easy with little hassle and networks can be achieved far more easily. No wires are essential. Wireless network keeps environment very neat and clean. There are several additional features of Wireless LANs by way of example broadband connectivity. Wifi provides high-speed connectivity and faster communication where cables are certainly not possible install for example in remote areas. The list from the Wifi features is long some other major features included Site survey, enterprise grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, Person mobility and easy access through Hotspots.
WiFi supports two different types of modes; they may be considered to be infrastructure and the other you are random. In Ad hoc Wireless connections can be made without central device called router or entry way. Most network administrators prefer random over infrastructure mode. Random how ever have issues also. Wifi devices connected using Random mode offers less security against unauthorized users. Ad hoc mode configured devices cannot disable SSID broadcast as opposed to infrastructure mode, this brings hackers into play, and taking advantage of random mode it's not hard to prevail in the wireless network. There's two major differences between those two modes that is the rate where they transfer data. Wife network standard 802.11g requires Ad hoc mode of communication to compliment 11Mbps bandwidth as opposed to it 54Mbps data transfer useage is supported using infrastructure mode. Hence Ad hoc mode is recognized as much slower than Infrastructure mode.
Wireless based networks are increasing all over the place; every organization is installation if it had not been deploying it before. Some cities have actually provided the whole city a wifi swap the town into hotspot, big example looking at us is Chicago. Chicago have installed huge transmitter in form of massive size dish of Wifi which broadcast Wireless LAN radio signals through out town. It provides high speed internet connectivity quite inexpensively. Laptops, a desktop, PDAs along with other Wireless LAN card installed devices have access to the network and have broadband connectivity on move. WiFi users increasing day-to-day therefore its hardware manufacturers are manufacturing the products on huge scale. They are often available in market with reasonable cost. Laptops, PDAs, mother boards of the latest desktop computer are generally feature build in wireless LAN cards. When not installed already inside your laptop one can buy PCMCI slot wifi card to setup for accessing wireless network. Wifi PCI cards will also be accessible in market. Now USB wifi can be found in short range but nevertheless works good.
Intelligent routers can be found in market which works to connect different devices to wireless network. These routers could be configured without or with PC. All is necessary to plug internet cable in Ethernet or USB port to router's appropriate port. When internet is available to routers it can be configured using its cp using IP 192.168.1.1. That's where we can enable SSID broadcasting or disable it and perform other functions. PCs can be mounted on routers to get more advance management which routers are unable to performs. PCs are typically forced to provide where network is very large and keeping tweaking its integrity and stability is very important.
Within this modern era everyone wants anything wireless, Wifi belongs to wireless technology family. There are many other wireless technologies which have evolved at about the time and Wifi is currently taken for granted and world is currently speaking about much advanced that has been enhanced wireless network known to be WiMax. WiMax beats Wifi technology on many bases including Speed of which data rates are transferred, range with which connection is done a great deal more. We have now to determine in the length of time WiMax will take over WiFi, and which technology will ultimately take over WiMax. Something is certain latest technologies in wireless technology help keep coming and may keep recovering from looked by brand new ones.
