A Survey on IEEE 802.11n 802.11 are just digits for someone from outside wireless but for people interested in wireless technologies they have a significant value. Institute for Electrical and Electronics Engineers (IEEE) sets up certain standards for researching technologies in certain fields. 802 is such standard which deals with local area networks and metropolitan area networks. 802.11 is the standard dealing with implementation of wireless-LAN. IEEE introduced 802.11 in order to improve communication
There was a time in our life when going wireless was a dream and was considered highly expensive but then started the era of WIFI. The first outcome of this wireless transmission was IEEE 802.11 standard for wireless data transmission and it progressed as a/b/n with the time. The last stand 802.11n was the real heavyweight and gained a lot of popularity based on its amazing performance. It gave almost 5 times increase in bandwidth using MIMO (Multiple Input Multiple Output) antenna technique. The
and therefore only the most important aspects are considered. The information originates from the IEEE standardization committee and two independent and recently published books. The standard will be explained, followed by the historical details and the protocol changes over time. After this the actual use and functionality is described and in the end will be a look at future trends. The IEEE 802.11 standard In today’s technological culture the term Wi-Fi is omnipresent and almost every device intended

The expansio¬¬¬¬¬n has caused many benefits to the end users but at the same time it has introduced problem of overlapping BSS (Basic Service Set) where BSS (i.e. WLAN cells) is fundamental block of IEEE 802.11 WLAN architecture. OBSS occurs due to two or more unrelated BSSs are used at the same place, at the same time and with the same frequency channel. With the expansion of channel bandwidth to 80 MHz (may be, 160 MHz) in upcoming standards, the OBSS
This paper is going to discuss wireless security from a broad view where I will go into why exactly wireless security is so important, especially today as the ways in which we are communicating is changing dramatically. From there I will discuss the multiple wireless securities that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions of the most dangerous wireless attacks out there
Network administrators and intrusion analysts need to be aware of the risks associated with 802.11 network deployment, and the techniques that can be used to identify malicious client activity.

a wired Local Area Network (Kolawole, 2014). In wireless LAN transmission making use of radio frequency to communicate over the air eliminates or at least minimizes the use of physically wired networks. From the beginning, IEEE 802.11 was designed to look and feel like IEEE 802 wired networks to include supporting all of the protocols and LAN management tools that operate on a wired LAN (O 'Hara & Petrick, 2005). The major differences in a wireless LAN and a wired LAN is of course that there are

or wires. What is Wi-Fi? Wi-Fi is a wireless technology brand that is owned by Wi-Fi Alliance Wi-Fi Alliance is a consortium of separate and independent companies agreeing to a set of common interoperable products based on the family of IEEE 802.11 standards. Wi-Fi certifies products via a set of established test procedures to establish interoperability. Those manufacturers that are members of Wi-Fi Alliance whose products pass these interoperability tests can mark their products and product
Scope and Objective Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia
the engineering principles of electronics towards creating devices and technology that benefit society. The Institute of Electrical and Electronics Engineers (IEEE) is the largest professional organization dedicated to advancing technology for societies benefit. As students become Electronic Engineers, they will become involved with the IEEE during their careers and help in developing new and beneficial technologies. Such examples of this emerging technology include: the development of Motor Vehicle
combination of both hardware inside a device and software used to create the connections. WiFi or Wireless LANs define a short-range wireless network typically used in an office or home setting that allows several users to access the network resources. IEEE 802.11 sets the standard for wireless LAN equipment and speeds and products under this standard are marketed as the WiFi brand (Certification Partners, 2012). When speeds are mentioned, it is typically in reference to the top speeds available but generally
widely used to access Internet and local networks without having to have a physical connection. I will finally assess WiMAX (Worldwide Interoperability for Microwave Access) that is used to provide Internet over a large distance. Bluetooth was an IEEE (Institute of Electrical and Electronics Engineers) 802.15 standard, but the standard is no longer sustained. Bluetooth supports speeds up to 24mb/s as well as different power ranges, which allows it to travel over certain distances. Short range can

technically a trademarked brand name for the wireless standard owned by the Wi-Fi Alliance, much like Bluetooth® is trademarked by the Bluetooth Special Interest Group. The Wi-Fi Alliance also defines Wi-Fi as any WLAN product that based on the IEEE 802.11 standard. However, only Wi-Fi products that have complete Wi-Fi Alliance interoperability certification testing successfully may use the Wi-Fi Certified trademark. • In its fledgling stages, Wi-Fi technology was almost solely used to wirelessly
(wireless fidelity) were the two networks evaluated, chosen because of increasing popularity and availability. Within the classification of Wi-Fi networks three IEEE standards were compared, the 802.11b, the 802.11g, and the 802.11a. Each option was compared on the criteria of speed, security, range, cost, and application. I recommend the use of the IEEE 802.11g standard for wireless connectivity. The 802.11g standard provides backward compatibility, it is compatible with earlier versions such as the popular

Abbreviation of Institute of Electrical and Electronics Engineers, pronounced I-triple-E. Founded in 1884 as the AIEE, the IEEE was formed in 1963 when AIEE merged with IRE. IEEE is an organization composed of engineers, scientists, and students. The IEEE is best known for developing standards for the computer and electronics industry. In particular, the IEEE 802 standards for local-area networks are widely followed. Anyone that has worked with a computer on a network has at some point been exposed
June, 1997 the IEEE, the body that defined the dominant 802.3 Ethernet standard, released the 802.11 standard for wireless local area networking. IEEE 802.11 standard supports transmission in infrared light and two types of radio transmission within the unlicensed 2.4GHz frequency band: Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS). The followings are development of wireless standards: Local Area Networks (IEEE 802) Wired Ethernet (IEEE 802.3) Wireless
