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

how the data is gathered from the end station and prepared for transmission. The main wireless protocol are: IEEE 802.11 covering wireless Ethernet; 802.15 dealing with wireless personal area networks (WPAN), including Bluetooth technology; and 802.16 for broadband wireless access. 802.11 The IEEE 802.11 specification family consists of four different, primary specifications: •     802.11 – applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency

expanded greatly and rapidly in recent years. 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

In 1991, two corporations, NCR along with AT&T came up the originator to 802.11, which were intended to be used with their cashiering system. The company’s initial wireless products were called WaveLan. The very first version of the 802.11 protocol was released in 1997 with speeds up to 2Mbps. Victor Hayes, a Dutch Engineer is known as the father of wifi, because he helped negotiate the initial standards within the IEEE (Institute of Electrical and Electronics Engineers). While wireless has been

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

of the wireless technologies and standards used for each of the networks types defined above. The figure indicates two major categories of wireless technologies: fixed and mobile. The figure also indicates 10 technologies in use: Bluetooth, irDA, 802.11, IR LAN, IR Bridge, Ricochet, RF Bridge, Cellular, MCS and Satellite. Virtually all of these tec... ... middle of paper ... ...e issues addressed in the 802.11i standard, third party software vendors are rapidly creating and marketing wireless

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

High performance Architecture for IP based multihop 802.11 Networks The concept of a forwarding node, which receives packets from upstream nodes and then transmits these packets to downstream nodes, is a key element of any multihop network, wired or wireless. While high-speed IP router architectures have been extensively studied for wired networks, the concept of a “wireless IP router” has not been addressed so far. This article provides all the problems and methods for increasing the throughput

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.
