WiFi is the other reputation for wi-fi or wireless network, this name is generally utilized by none technical users who just learns how to access internet wirelessly, they are fully aware pretty much nothing beyond that. WiFi is simply short form for wireless fidelity. However many advance users aren’t well aware of this terminology either, it can be ,more known having a name of Wifi. WiFi term is constructed in lots of ways which can be, Wifi, WiFi, WIFI, Wi-Fi fiwi etc.
Wi-Fi was designed by Wi-Fi alliance in 1985 it had been some time in the event it had not been utilized 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 associated with Wifi is mainly 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 in the computer communications in countless organizations worldwide
Wifi uses all the networks referring to almost any 802.11 network standards which can be set by IEEE. IEEE is short form of Institute of electric and electronic engineering. There are lots of enhancements manufactured in standards of 802.11 and 802.11a, 802.11b along with other dual networks. The latest standard of 802.11 folks are 802.11y. Other known standards are 802.16, these are the standards for upcoming technology known to be WiMax. There is an additional known pair of standards for Ethernet it is known to become IEEE 802.3.
Development of Wifi networks remains to be on-going world wide this massive growth raises security issues. Wifi is among the most widely used network worldwide and many organizations transfer their sensitive data using Wireless networks. Increased use of Wireless network increases potentially risks of the security in the users or organization. Wireless network carries data of the type, which can be normal data in components of information or it might encrypted or perhaps highly sensitive. WiFi security mechanism insures the certain degree of data integrity and confidentiality just as wired network provides. You can definitely proper safety measures aren’t adopted properly intruders can attack the network and will cause major problems for not merely network but privacy of users also.
At one time when cables were utilized to network many computers together. Hardware like routers, hubs, switches etc were essential for communication between computers, but Wifi brought hi-tech change in communication of computers by giving wireless connectivity features. It keeps things very easy very little hassle and networks can be created far more easily. No wires are required. Wireless network keeps environment very nice and clean. There are lots of more features of Wireless LANs for example broadband connectivity. Wifi provides high speed connectivity and faster communication where cables are certainly not possible to install for instance in remote areas. The list from the Wifi features is long various other major features included Site survey, enterprise grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, User mobility as well as simple access through Hotspots.
WiFi supports two several types of modes; they’re considered infrastructure and yet another an example may be random. In Random Wireless connections can be achieved 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. Random mode configured devices cannot disable SSID broadcast in contrast to infrastructure mode, this brings hackers into play, and ultizing random mode it isn’t very difficult to prevail to the wireless network. There are 2 major differences between those two modes which is the rate from which they transfer data. Wife network standard 802.11g requires Random mode of communication to support 11Mbps bandwidth not like it 54Mbps bandwith is supported using infrastructure mode. Hence Random mode is considered much slower than Infrastructure mode.
Wireless based networks are increasing every where; every organization is installation whether it was not using it before. Some cities have actually provided the entire city a wifi change the town into hotspot, big example looking at us is Chicago. Chicago have installed huge transmitter in shape of big size dish of Wifi which broadcast Wireless LAN radio signals through town. It gives you internet connectivity very cheaply. Laptops, personal computers, PDAs as well as other Wireless LAN card installed devices can access the network and obtain broadband connectivity on move. WiFi users increasing day-to-day therefore its hardware manufacturers are manufacturing the items on huge scale. They are easily obtainable in market with reasonable cost. Laptops, PDAs, mother boards of contemporary desktop computer are generally come with build in wireless LAN cards. If not installed already within your laptop one can possibly buy PCMCI slot wifi card to setup for accessing wireless network. Wifi PCI cards are also widely accessible in market. Now USB wifi are offered also in short range but still works good.
Intelligent routers can be bought in market which fits to connect different devices to wireless network. These routers might 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 is usually configured using its control panel using IP 192.168.1.1. This is where we could enable SSID broadcasting or disable it and perform other functions. PCs can even be mounted on routers for additional advance management which routers cannot performs. PCs are mostly forced to be utilized where network is big and keeping and looking after its integrity and stability is vital.
In this modern era each one wants almost everything wireless, Wifi belongs to wireless technology family. There are plenty of other wireless technologies which may have evolved at about the time and Wifi is currently overlooked and world is currently speaking about much advanced and enhanced wireless network regarded as WiMax. WiMax beats Wifi technology on many bases which include Speed at which data minute rates are transferred, range which connection is made a great deal more. We now have to determine in the length of time WiMax will need over WiFi, and which technology may ultimately take control WiMax. One thing is for sure latest technologies in wireless technology help keep coming and can keep getting over looked by brand new ones.
