Wireless LAN Essays

2.1 Wireless LAN Infrastructure Devices Proper WLAN infrastructure design requires understanding and deploying QoS (Quality of Service) on the wireless network to ensure end-to-end data / video/voice quality on the entire network. Like a traditional wired LAN, WLAN is a grouping of computers and peripheral devices that share a common communications backbone. As per the name itself, a WLAN allows users to connect to the LAN through radio transmission. The below mentioned are the most common components

The importance of the LANs has been made the developing of it is the main purpose to make it easy to setup or upgrade a network. The result of this developing has been made two types of networks, one is wired LAN and the other is wireless LAN. Protocols of Wired and Wireless LANs Wired LANs has six types of protocols each type has its own media and topology to setup a network that is using it. These types

Pros & Cons Pros • Easy to install: Wireless networks have become commonplace with Wireless N being the current standard. Wireless router is easy to purchase, connect it to the Internet, and install in either at home or office setting, it is recommended to hire a network professional to install and setup the wireless router in order to ensure that you have high level of security enabled and there is sufficient wireless coverage throughout the whole areas. • Cost: The cost of the hardware is low,

COBRANET - OVERVIEW AND ARCHITECTURE CobraNet is an amalgamation of software, network protocol and hardware which entitles the distribution of various channels of real time, high quality digital audio over the Ethernet network. Cobranet operates at the 2nd OSI layer i.e. Data link layer.CobraNet was designed to ensure numerous audio channels to be transmitted over Ethernet technology .It is basically a collection of CobraNet interface and a network protocol. It enables the transport of high quality

802.11 wireless LANs whereas the portal is the one which provides a point for interconnection between a wired LAN and an 802.11 wireless LAN. 2)Why are multiple accesspoints in WLL installed in a building? Answer: Installing multiple accesspoints in WLL in a building properly enhances the performance of the wifi networks overall. It helps to avoid co-channel and adjacent channel interferenc as too much co-channel or adjacent channel interference will degrade the performance of your wireless network

1.1 Wireless communication There are various generation in the wireless system. We are running with the 4 G wireless system which is more focused on the high speed data communication. The demand for higher capacity with low error has raised manifolds, mainly due to cellular telephony although expected to be soon eclipsed by wireless data applications. The various digital signal processing algorithms like IFFT, FFT can be implemented with the advent of modern chip technology. Due to the success of

reliable by preventing any chance of Data loosing that might happen due failure to devices and links. As show in the diagram below: 2. LAN, WAN, WLAN and PAN

Asian American Cathy Song drew closer to her Korean-Chinese ancestry, and was able to describe in a clear image of the two women she represent, one being the industrial American women and the other one being the Chinese caretaker. Cathy Song was born and raised in Hawaii making her an American by birth right. This fact did not keep her from engulfing her Korean-Chinese heritage. In the poem “Lost Sister”, Song isolates a young girl who struggles to find who she truly is in China, because of all the

Disconnected from The Good Earth The land beneath our feet is the foundation of life, providing nutrients to plants, and a home for animals. In the beginning of The Good Earth, Wang Lung is deeply connected with the Earth due to his farming occupation, yet as he becomes prosperous, he gradually distances himself from the foundation of life. Throughout the novel The Good Earth, by Pearl S. Buck, Wang Lung maintains a strong work ethic and passion however, the cultural collision between traditional

In 1884, F.B. Morse, developed the Morse code for efficient communication. It is because of the simplicity yet efficaciousness that these Morse codes are used even today. Morse codes are composed of ditz and dahs, which are used by a number of people for communication purposes. Moreover, the use of these codes is not limited for simple communication. It is also used for encrypted communication for security purposes. This code is used for Emergency Signaling (SOS) for all kinds of receivers. This

Mobile Wi-Fi plans allow service subscribers to use their internet connected phone while on the move at highly affordable rates. One of the major players in the US mobile wifi market is The Los Angeles based FreedomPop. The company currently provides wireless data, text and voice service for Sprint and Clearwire mobile service carriers. According to Ingrid Lunden, a columnist at TechCrunch, FreedomPop is working hard to sway a good number of people to move away from the traditional mobile carriers by

has actually now gone wireless. Smart phone, as the name suggests, supplies movement. It is a portable communication device. One can bring it anywhere. It is enabled by satellites that transmit signals for the phone to receive and send. It is very practical as one can use it anywhere irregardless of time and area. People everywhere have seen the development of communication innovation, from a phone that utilizes wires to one that no longer requires any. In some places, wireless phones were provided

sufficient conditions on the minimum number of wavelengths required to be wide-sense nonblocking for multicast communication is derived. The linear array and ring networks are popular and find application in any form of network including WAN, MAN and LAN [4-10]. We also expect the results to be obtained in this paper, is to be a representative of the performance obtainable from practical long-haul networks like mesh

5. METHODOLOGY 5.1 Secure Multipath Routing Protocols in Wireless Sensor Networks Till date many routing protocols have been proposed for wireless sensor networks, but only few of them consider the problem of security [4] and most of them are developed without any security concern. So in this section we focus at selected multipath routing protocols in order to cope with the various attacks. For avoiding intruders attacks in HWSN various methods and algorithms are implemented out of that Professor

Throughout The Good Earth we come across many tough conflicts both internally and externally, but even so, many of them we can relate to. Wang Lung, O-Lan, Lotus, Ching, and the rest of Wang Lung’s family all must deal with conflicts between each other, with nature, and within themselves. But they aren’t so different from us and we find ourselves in many of the same situations that our beloved characters do. Wang Lung deals with guilt and greed throughout the novel and it is something that most people

and he quickly travels back to his cozy dwelling made of the same earth upon which he daily labors. Upon entering, he is relieved to discover delicious food already lined up on the table, a new-found luxury for Wang Lung since he married. His wife, O-lan, constantly provides him with necessities for life. In this isolated area of China during the early twentieth century, a woman is expected to stay quiet and well-behaved, as a slave to men. Technology could not be more distant, and the agrarian society

After him and O-Lan returned home, they began to work hard on producing crops from their land. Wang-Lung began to harvest land avidly, and birth flourishing crops. He began to acquire more and more money, and built a larger earthen house, adding more courts to comfortably fit all of his children and O-Lan. As Wang-Lung is becoming wealthier, he begins to change his attitude towards O-Lan, as she, in his eyes, is extraordinarily ugly. She does not fit

fall. “ -- Aesop. In the book The Good Earth, Pearl Buck uses Wang Lung’s marriage to O-lan to show that as a unified people they make each other whole, and fill the gaps that the other has. Before Olan, Wang Lung had different views on schooling, slaves, farming, and loyalty. As Wang Lung married Olan they started very different because of the different up bringings of both of them. Neither O-lan nor Wang Lung went to school when they were children, so they didn’t find it necessary for their
