Essay On Wireless Communication

The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society.

Wireless networking has proven to become a vital fragment in companies and homes. Wireless LANs has exemplified its advantage in mobility, productivity, convenience and deployment compared to wired LANs. The Institute of Electrical and Electronics Engineers, IEEE, has continually expanded upon the original 802.11 as the popularity of Wireless LANs grew. The new standard for WLAN, 802.11ac, came from a history of standards dating back from 1997. The benefits of Wireless LAN has continually propagated as new stan... ... middle of paper ... ...lacing traditional Wi-Fi.

This will allow us to gain a more fundamental insight in the possibilities and restrictions of wireless LAN. Generally, wireless LAN proved to be a reliable and reasonably fast mobile networking solution. For most purposes, the bandwidth it provides should suffice, although cabled LANs offer more possibilities to extend the bandwidth. In situations where mobility is as good a criterion as bandwidth, a wireless LAN should certainly be considered a serious option.

Our Project demonstration is based solely on wireless internet technology. Basically, what we set out to do was to prove that a wireless internet connection could actually be made, and that it could made to be, at least somewhat, secure. Our goals are listed below: 1.-Setup a wireless connection to the internet. 2.-Ensure that the connection can be made and that the signal will remain constant. 3-Using WEP(wired equivalent privacy), ensure that the wireless connection can be made secure.

Wireless Technology Wireless technology is an industry that has seen much growth and progress in the years following the inception of the internet and cell phones. Our society has progressed to the point to where we can no longer function without this technology. Business, travel, and everyday life now are dependant on wireless technology. Wireless technology is just what its name implies, communicating or computing without wires and phone lines. Wireless technology uses a variety of different devices such as desktop and laptop computers, personal digital assistants (PDA’s), cell phones, and many others.

Most Common Wireless Networking Access Methods Wireless communication has created an ever-evolving need for devices that are faster and applicable to a variety of lifestyle situations. As new devices are created, security measures have to be implemented and policies have to be adapted as the way we live changes in response to the technology available to us. Two of the most common wireless communication access methods are Bluetooth and WiFi. Bluetooth technology creates personal area connections with handheld / mobile devices. The Personal Area Network (PAN) created can operate at a distance up to 100 meters (328 feet) depending on the individual device specifications.

Information Technology – Wireless local-area Networks (WLAN) In today’s world where organizations need to keep in contact with employees there seem to be more ways than ever to stay connected. This can be a burden for small organizations that do not have a large information technology (IT) staff to keep them updated with the latest technologies (Cisco, 2004). A significant way for employees to stay in touch besides cell phones, laptops and hand held computers is wireless local area networks (WLAN). Also known as LAWN, a wireless local-area network uses high frequency radio waves rather than wires to communicate between computers or other devices (Webopedia, 2004). Business owners are now recognizing the benefits of incorporating wireless network into their organizations.

Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too. Wired ones are practically safer.

So, it is important to secure the wireless network by utilizing small time to be saved in future. The security of wireless networks becomes more vital because it is most commonly used in every field. There are number of practices developed for securing wireless networks till now and because of the scope, and its importance, more research is being done for more secure wireless networks in future ( Solms, BV & Marais, E 2004). Wireless Network Security 1. Wireless Networking Basics According to (Vacca, JR 2006) The term wireless networking means the technology that facilitates two or more computers to communicate using standard network protocols, but without network cabling.

Wi-Fi is a technology that connects your computer to an internet access point using radio signals. Also this technology is very similar to smartphones and TVs as they all use radio waves. Wi-Fi is a very important part of technology today as it allows people to connect with each other and to access information that was probably difficult to obtain before Wi-Fi. Wi-Fi is just accessing the internet like you are directly connected with an Ethernet cable however with Wi-Fi you can access the internet wirelessly as long as you are in the routers radius. Wi-Fi is a very important part of peoples live and there are many companies that make a lot of money form just selling their Wi-Fi packages such as Virgin Media and BT.
