8/10/2016 - One word About Wifi or Wifi Technology
Posted in Unspecified

 

 

WiFi may be the other name for wi-fi or wireless network, this name is mostly employed by none technical users who just understands how to access internet wirelessly, they understand basically nothing beyond that. WiFi is essentially short form for wireless fidelity. However many advance users aren't knowledgeable of this terminology either, it is ,more known which has a name of Wifi. WiFi term is presented in many ways which are, Wifi, WiFi, WIFI, Wi-Fi fiwi etc.

Wi-Fi was created by Wi-Fi alliance in 1985 it had been enough time if it was not utilized as commercially but were just set to certain organizations for testing purposes. Wi-Fi Alliance is pioneer in developing WiFi technology as well as the hardware linked to 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 some of the computer communications in countless organizations all over the world

 

Wifi uses all the networks referring to any type of 802.11 network standards that's set by IEEE. IEEE is short form of Institute of electric and electronic engineering. There are various enhancements produced in standards of 802.11 and 802.11a, 802.11b and also other dual networks. The newest standard of 802.11 household is 802.11y. Other known standards are 802.16, these are the standards for upcoming technology considered WiMax. There is yet another known pair of standards for Ethernet you are able to to become IEEE 802.3.

Growth of Wifi networks is still ongoing around the world this massive growth raises security issues. Wifi is easily the most trusted network world wide and many organizations transfer their sensitive data using Wireless networks. Increased utilization of Wireless network increases potentially risks of the security in the users or organization. Wireless network carries data of each type, that may be normal data in components of information or it could encrypted or even highly sensitive. WiFi security mechanism insures the certain level of data integrity and confidentiality just as wired network provides. However if proper safety measures are certainly not adopted properly intruders can attack the network and can cause major damage to not just network but privacy of users also.

The times when cables were used to network many computers together. Hardware like routers, hubs, switches etc were required for communication between computers, but Wifi brought hi-tech alternation in communication of computers by offering wireless connectivity features. It simply keeps things quite simple without much hassle and networks can be created a lot more easily. No wires are essential. Wireless network keeps environment very elegant. There are numerous more features of Wireless LANs as an example broadband connectivity. Wifi provides very fast connectivity and faster communication where cables usually are not possible to install by way of example in remote areas. Their email list of the Wifi features is long some 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 a variety of modes; these are regarded as infrastructure and the other one is random. In Random Wireless connections can be created without central device called router or access point. 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 as opposed to infrastructure mode, this brings hackers into play, and using ad hoc mode it isn't hard to prevail in to the wireless network. There's two major differences between these modes that is the rate of which they transfer data. Wife network standard 802.11g requires Random mode of communication to support 11Mbps bandwidth contrary to it 54Mbps data is supported using infrastructure mode. Hence Ad hoc mode is regarded as 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 complete city a wifi change the town into hotspot, big example looking at us is Chicago. Chicago have installed huge transmitter in form of big size dish of Wifi which broadcast Wireless LAN radio signals throughout the location. It offers broadband internet connectivity very cheaply. Laptops, desktop computers, PDAs and also other Wireless LAN card installed devices can access the network and acquire high-speed connectivity on move. WiFi users increasing day-to-day therefore its hardware manufacturers are manufacturing the merchandise on huge scale. These items are easily for sale in market with reasonable cost. Laptops, PDAs, mother boards of contemporary pc are generally come with build in wireless LAN cards. When not installed already within your laptop one can possibly buy PCMCI slot wifi card to install for accessing wireless network. Wifi PCI cards can also be widely available in market. Now USB wifi are offered also abbreviated range but still works good.

 

Intelligent routers can be bought in market which works to get in touch different devices to wireless network. These routers may be configured with or without PC. All is needed to plug internet cable in Ethernet or USB port to router's appropriate port. When internet can be obtained to routers it could be configured using its control panel using IP 192.168.1.1. That is where we are able to enable SSID broadcasting or disable it and perform other functions. PCs can even be mounted on routers for further advance management which routers cannot performs. PCs are mainly needed to supply where network is very large and keeping and maintaining its integrity and stability is very important.

 

In this modern era each one wants anything wireless, Wifi belongs to wireless technology family. There are numerous other wireless technologies which have evolved at about the time and Wifi is neglected and world has become discussing much advanced that has been enhanced wireless network considered WiMax. WiMax beats Wifi technology on many bases which include Speed from which data rate is transferred, range which connection is created and a whole lot. We now have to determine in the span of time WiMax will need over WiFi, and which technology will ultimately take control WiMax. A very important factor is certain latest technologies in wireless technology could keep coming and definately will keep going through looked by new ones.
