A Word About Wifi or Wifi Technology

WiFi is one other term for wireless internet or wireless network, this name is mostly employed by none technical users who just knows how to gain access to internet wirelessly, they know more or less nothing beyond that. WiFi is basically short form for wireless fidelity. However many advance users aren't well aware of the terminology either, it's ,more known with a title of Wifi. WiFi term is written in lots of ways which are, Wifi, WiFi, WIFI, Wi-Fi fiwi etc.




Wi-Fi was introduced by Wi-Fi alliance in 1985 it absolutely was the time when it wasn't used as commercially but were just set to certain organizations for testing purposes. Wi-Fi Alliance is pioneer in developing WiFi technology and all of the hardware associated with Wifi is mostly certified by Wifi Alliance compliance. Wifi later developed properly and than eventually lunched for public used in USA in 90's, gradually wifi become standards for all of the computer communications in countless organizations around the world

There is a time when cables were used to network many computers together. Hardware like routers, hubs, switches etc were necessary for communication between computers, but Wifi brought high tech change in communication of computers by providing wireless connectivity features. It really keeps things quite simple without much hassle and networks can be made much more easily. No wires are required. Wireless network keeps environment very neat and clean. There are numerous other top features of Wireless LANs as an example top speed connectivity. Wifi provides top speed connectivity and faster communication where cables aren't feasible to install for example in remote areas. The set of the Wifi features is long several other major features included Site survey, enterprise grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, End user mobility and easy access through Hotspots.

WiFi supports two various kinds of modes; they are considered to be infrastructure and another one is ad hoc. In Ad hoc Wireless connections could be made without central device called router or access point. Most network administrators prefer ad hoc over infrastructure mode. Ad hoc how ever have issues also. Wifi devices connected using Ad hoc mode offers less security against unauthorized users. Ad hoc mode configured devices cannot disable SSID broadcast on the other hand to infrastructure mode, this brings hackers into play, and using ad hoc mode it's not very difficult to prevail in to the wireless network. You will find two major differences between those two modes that's the rate at that they transfer data. Wife network standard 802.11g requires Ad hoc mode of communication to aid 11Mbps bandwidth on the other hand to it 54Mbps data transfer is supported using infrastructure mode. Hence Ad hoc mode is considered much slower than Infrastructure mode.

Wireless based networks are increasing all over the place; every organization is installing it when it wasn't utilizing it before. Some cities have actually provided the entire city a wifi and turn the city into hotspot, big example in front of us is Chicago. Chicago have installed huge transmitter in shape of big size dish of Wifi which broadcast Wireless LAN radio signals through the city. It provides top speed internet connectivity very cheaply. Laptops, desktop computers, PDAs and other Wireless LAN card installed devices can access the network and get high speed connectivity on move. WiFi users increasing daily therefore its hardware manufacturers are manufacturing the merchandise on huge scale. The products are easily available in market with reasonable cost. Laptops, PDAs, mother boards of latest desktop computer are mostly come with build in wireless LAN cards. If it's not installed already in your laptop you can buy PCMCI slot wifi card to put in for accessing wireless network. Wifi PCI cards will also be widely available in market. Now USB wifi are also available for brief range but still works good.

Intelligent routers are available in market which works for connecting different devices to wireless network. These routers could 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 is available to routers it can be configured which consists of control panel using IP 192.168.1.1. That's where we are able to enable SSID broadcasting or disable it and perform other functions. PCs can be attached with routers for more advance management which routers can not performs. PCs are generally required to be utilized where network is huge and keeping and maintaining its integrity and stability is very important.

In this modern era everybody wants every thing wireless, Wifi belongs to wireless technology family. There are so many other wireless technologies which may have evolved around the full time and Wifi is currently taken for granted and world is now speaking about much advanced and enhanced wireless network considered to be WiMax. WiMax beats Wifi technology on many bases including Speed of which data rate is transferred, range with which connection is made and so much more. We now have to see in simply how much time WiMax will dominate WiFi, and which technology could eventually take over WiMax. One thing is for certain latest technologies in wireless technology can keep coming and could keep getting overlooked by new ones.
