802.11 Research Paper

In the pursuit of opening a great venture with my business partner we are hoping to

Should Wi-Fi technology in the 21st century be kept from the wild? In The Atlantic article “Wifi in the Woods” by Jason Mark, the internet is difficult for people to get away from. Mark discusses that a group of people travelling to the tundra, including DJ Spooky (a record producer), adapted to their environment, when they encountered a loss of internet signal. He also explained that companies are laying out plans to add internet to wild country. Furthermore, he discusses the pros like checking weather information and global connectivity, and the cons like no escaping from government oppressors and losing the calmness of the wood. Wifi technology is of more positive development in rustic

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

802.11 WLANs use CSMA/CA, the devices use a four-way handshake to gain access to the airwaves to ensure collision avoidance, and also to know about hidden nodes from different wireless standard.

The 802.11 provides the wireless LAN services for the clients, the access points, and the network connecting them. The association service is used by mobile stations to connect themselves to APs. Reassociation lets a station change its preferred AP. Either the station or the AP may also disassociate, breaking their relationship. Stations must authenticate to use a security scheme before they can send frames via the AP. With WPA2, the AP can talk to an authentication server that has a username and password database to determine if the station is allowed to access the network. Before WPA, WEP is used but it is easy to compromise. The distribution service determines the route for wireless or wired network. The integration service is used when

Apple’s iPhone and iPad has gained a large share of the smart phone and computer tablet market.   Mitchell (2011) noted that competitors have released their own versions, and almost overnight, a new technological commodity has become a competing force in the business world. Apple has introduced many innovative features and has redefined the mobile-device and computer tablet landscape forcing the competition to evolve and play catch-up in many cases (DesRosiers, 2010).

It’s very important to determine the device and application requirements based on bandwidth, protocols and frequency. In wireless network, bandwidth, protocols and sometime environmental conditions affect the speed of the channel so we need to calculate the aggregate throughputs before designing the network. Today, users carry Wi-Fi devices such as notebooks, laptops, tablets and Smartphone’s so total throughput must be calculated by estimating number of connections rather than the number of the seats. Some common wireless networking standards such as 802.11a/b/g/n invented in the IEEE association must be supported by wireless network. For better performance and for faster devices (802.11n devices), dual-ratio access points should be deployed. Table1 [3] illustrate the different IEEE standards and throughput.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Being one of the most extended wireless technologies in wireless communication networks, IEEE 802.11 wireless LAN offers simplicity, flexibility and cost effectiveness as its main characteristics. This wireless technology provides communication between peoples everywhere and computing environment at any place where peoples needed wireless communication to communicate. At the same time, number of users for multimedia applications increased. Nowadays, peoples want more of the high-speed video, audio, voice and web services anywhere and anytime. Unfortunately, these multimedia applications require Quality of Service support such as guaranteed bandwidth, delay, jitter, and error rate. This might be challenging as

Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.

The wireless network consists of four fundamental components: The transmission of data, utilizing radio frequencies, Access points (AP) which provide a connection to the organization 's network or private network and users. All of these components provide a way for an attack which can result in compromise of security objectives of availability, integrity and confidentiality.
