Any Phrase Concerning Wifi or Wifi Engineering

WiFi is one other term for wireless internet or wireless network, this name is certainly caused by 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 simply short form for wireless fidelity. However many advance users aren’t well aware with this terminology either, it is ,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 was the time when it was not used as commercially but were just set to certain organizations for testing purposes. Wi-Fi Alliance is pioneer in developing WiFi technology and most of the hardware associated with Wifi is certainly caused by certified by Wifi Alliance compliance. Wifi later developed properly and than eventually lunched for public use within USA in 90’s, gradually wifi become standards for a lot of the computer communications in countless organizations around the globe

Wifi uses most of the networks discussing any kind of 802.11 network standards which is set by IEEE. IEEE is short type of Institute of electric and electronic engineering. There are plenty of enhancements produced in standards of 802.11 and 802.11a, 802.11b and other dual networks. The newest standard of 802.11 family is 802.11y. Other known standards are 802.16, they’re the standards for upcoming technology known to be WiMax. There’s yet another known set of standards for Ethernet it is known to be IEEE 802.3.

Growth of Wifi networks is still on going globally this huge growth raises security issues. Wifi is probably the most popular network globally and many organizations transfer their sensitive data using Wireless networks. Increased usage of Wireless network increases potentially risks of the security of the users or organization. Wireless network carries data of each and every type, home automation which can be normal data in bits of information or it may 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 security measures aren’t adopted properly intruders can attack the network and can cause major damage never to only network but privacy of users also.

There is a period 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 change in communication of computers by providing wireless connectivity features. It really keeps things very simple without much hassle and networks can be made a lot more easily. No wires are required. Wireless network keeps environment very neat and clean. There are numerous other top features of Wireless LANs like high speed connectivity. Wifi provides high speed connectivity and faster communication where cables aren’t feasible to set up like 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’re known to be infrastructure and one other one is ad hoc. In Ad hoc Wireless connections can 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 in contrast to infrastructure mode, this brings hackers into play, and using ad hoc mode it is not very difficult to prevail into the wireless network. You can find two major differences between these two modes that’s the rate at which they transfer data. Wife network standard 802.11g requires Ad hoc mode of communication to support 11Mbps bandwidth in contrast to it 54Mbps data transfer is supported using infrastructure mode. Hence Ad hoc mode is recognized as much slower than Infrastructure mode.
