A Word About Wifi or Wifi Technology

WiFi may be the other term for wireless internet or wireless network, this name is generally utilized by none technical users who just learns how to access internet wirelessly, they do know pretty much nothing beyond that. WiFi is actually short form for wireless fidelity. However many advance users usually are not familiar with this terminology either, it is ,more known having a name of Wifi. WiFi term is written in many ways which can be, Wifi, WiFi, WIFI, Wi-Fi fiwi etc.

public free wifi

Wi-Fi was introduced by Wi-Fi alliance in 1985 it absolutely was the time if it wasn't utilized as commercially but were just set to a particular organizations for testing purposes. Wi-Fi Alliance is pioneer in developing WiFi technology and all the hardware related to Wifi is generally certified by Wifi Alliance compliance. Wifi later developed properly and than eventually lunched for public utilization in USA in 90's, gradually wifi become standards for most of the computer communications in countless organizations around the globe


Wifi uses every one of the networks discussing any sort of 802.11 network standards which can be set by IEEE. IEEE is brief kind of Institute of electric and electronic engineering. There are various enhancements manufactured in standards of 802.11 and 802.11a, 802.11b as well as other dual networks. The most up-to-date standard of 802.11 family is 802.11y. Other known standards are 802.16, these are the standards for upcoming technology known to be WiMax. There is yet another known list of standards for Ethernet it is known to be IEEE 802.3.


Development of Wifi networks continues to be on-going around the world this huge growth raises security issues. Wifi is the most popular network worldwide and a lot of organizations transfer their sensitive data using Wireless networks. Increased use of Wireless network increases potentially hazards of the safety in the users or organization. Wireless network carries data of every type, which can be normal data in items of information or it can encrypted or perhaps highly sensitive. WiFi security mechanism insures the certain level of data integrity and confidentiality just as wired network provides. You can definitely proper precautionary features usually are not adopted properly intruders can attack the network and may cause major problems for not merely network but privacy of users also.

At one time when cables were chosen to network many computers together. Hardware like routers, hubs, switches etc were essential for communication between computers, but Wifi brought advanced alternation in communication of computers by offering wireless connectivity features. It simply keeps things very easy without much hassle and networks can be achieved far more easily. No wires are needed. Wireless network keeps environment very elegant. There are several other functions of Wireless LANs for instance high speed connectivity. Wifi provides high speed connectivity and faster communication where cables usually are not feasible to install for example in remote areas. Their email list in the Wifi features is long a few other major features included Site survey, enterprise grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, Consumer mobility and simple access through Hotspots.


WiFi supports two various kinds of modes; they may be considered to be infrastructure and yet another an example may be random. In Ad hoc Wireless connections can be produced without central device called router or feeder point. Most network administrators prefer random over infrastructure mode. Ad hoc 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 utilizing random mode it's not hard to prevail in the wireless network. There are 2 major differences between these two modes this is the rate of which they transfer data. Wife network standard 802.11g requires Random mode of communication to aid 11Mbps bandwidth contrary to it 54Mbps data transfer is supported using infrastructure mode. Hence Random mode is recognized as much slower than Infrastructure mode.


Wireless based networks are increasing all over the place; every organization is installation if it wasn't making use of it before. Some cities have actually provided the entire city a wifi and switch the location into hotspot, big example in front of us is Chicago. Chicago have installed huge transmitter healthy of big size dish of Wifi which broadcast Wireless LAN radio signals during the city. It offers internet connectivity with a small outlay. Laptops, a desktop, PDAs and other Wireless LAN card installed devices can access the network and have high speed connectivity on move. WiFi users increasing everyday therefore its hardware manufacturers are manufacturing the items on huge scale. The products are often accessible in market with reasonable price. Laptops, PDAs, mother boards of contemporary pc are generally feature build in wireless LAN cards. When not installed already in your laptop you can buy PCMCI slot wifi card to set up for accessing wireless network. Wifi PCI cards will also be widely available in market. Now USB wifi are offered also for brief range but nevertheless works good.


Intelligent routers are available in market which works to connect different devices to wireless network. These routers can be configured with or without PC. All is required to plug internet cable in Ethernet or USB port to router's appropriate port. When internet can be acquired to routers it could be configured having its cp using IP This is why we are able to enable SSID broadcasting or disable it and perform other functions. PCs may also be mounted on routers to get more advance management which routers can't performs. PCs are mainly required to be used where network is very large and keeping and its integrity and stability is essential.


On this modern era everyone wants almost everything wireless, Wifi is owned by wireless technology family. There are numerous other wireless technologies who have evolved at about the time and Wifi is now taken for granted and world is currently talking about much advanced and enhanced wireless network known to be WiMax. WiMax beats Wifi technology on many bases such as Speed at which data minute rates are transferred, range in which connection is manufactured and so much more. Today we have to determine in the length of time WiMax will need over WiFi, and which technology may ultimately control WiMax. Another thing is certain latest technologies in wireless technology can keep coming and can keep recovering from looked by a.
