Wi Fi Sector

...York, USA ABSTRACT Sectorized antennas provide an attractive solution to increase wireless network capacity through interference mitigation. Despite their increasing popularity, the real-world performance characteristics of such antennas in dense wireless mesh networks are not well understood. We demonstrate our multi-sector antenna prototypes and their performance through video streaming over an indoor wireless network in the presence of interfering nodes. We use our graphical tool to vary the sender, receiver, and interferer antenna configurations and the resulting performance is directly visible in the video quality displayed at the receiver. Categories and Subject Descriptors C.2.1 [Network Architecture and Design]: Wireless Communication; C.4 [Performance of Systems]: Measurement Techniques We have developed a demonstrator that complements our previous measurement campaigns [3, 4] and its primary goal is to demonstrate the operation, the challenges, and the resulting performance of sectorized antennas in real-world dense 802.11 wireless mesh networks. We have designed a four-sector antenna [2] for operation in the 5GHz band with off-the-shelf 802.11 wireless cards. We equip a number of wireless nodes with these antennas and place them in vicinity of each other. We stream video content from a sender to a receiver in the presence of an interfering node while varying antenna configuration (i.e., sector activation) at these nodes. The perceived video quality is......

Wi-Fi Security

...Wi-Fi is growing rapidly in mainstream America. It seems that everywhere I go, there is a sign posted offering "free Wi-Fi". Are these so-called "hotspots", as secure as they are handy? Or, are hackers somewhere lingering waiting to take advantage of some unsuspecting user. Although wireless networks are convenient, they may not necessarily be secure. I use Wi-Fi at home and it seems to work for my family and me. My main concern when it was purchased was speed. However, now that time has progressed, I have become quite concerned about its security. Through further research, I found that I some experts suggested that Wi-Fi is safe, secure, and needs only normal security settings. While some experts say that Wi-Fi poses great risks to one's internet security. A wireless network functions by sending information through radio waves. This makes it easier for someone to intercept. Piraters do not have to be near you to pick up and intercept a signal. One way I have found that this is often done is on wireless peer-to-peer networks. Which is mainly at those ever so convenient public hotspots. Frequent use of public hotspots promote very high security risks for PCs as well as personal information stored on the PC. Constant precautions have to be maintained when using a wireless connection. To start, a strong password comes highly recommended. As well as......

...VoIP Voice over IP Hani Aladmaai Prof. Ali Bicak IT-520: Enterprise Infra and Networks Introduction VoIP or Voice over Internet Protocol is an IP based approach to transmitting voice over a computer network. It allows a person to make voice calls using an Internet connection instead of using a phone line. The user can make phone calls free (in certain circumstances), or they may get a service provider and pay a very low rate. How VoIP works is, it converts your voice into a digital signal that will travel over the Internet. First to send voice over a digital network, it must first be converted to digital and converted back to analog at the receiving end. VoIP may allow you to make a call directly from a computer, via VoIP programs such as Skype, a special VoIP phone, or your traditional phone connected to a special adapter. The research paper will begin with an introduction as to what VoIP is, what it accomplishes, what purpose it serves and how it works; also how it is configured. Next it will discuss some of advantages and disadvantages. Legal issues will also present on the usage of the VoIP. What is VoIP?

Evolution of Wi-Fi

...The Evolution of Wi-Fi Charles Williams Albert Acuna ISSC340 American Military University Abstract From the creation of the IEEE standard in 1997 to current times Wi-Fi has evolved dramatically over the years. An idea to provide connectivity to devices with the absence of cables was adopted globally. Each year brings about new ways of utilizing wireless technology. This study aims to cover Wi-Fi from inception to present day and prospects for the future. The Evolution of Wi-Fi What exactly is Wi-Fi? A popular misconception is that Wi-Fi stands for “wireless fidelity”, however, it can be described as, a technology that uses radio waves to provide internet and network connectivity. The Wi-Fi Alliance, a non-profit organization founded by six companies in 1999, defines Wi-Fi simply as “connectivity”, connectivity in a way that provides freedom and the ability to move about without being tethered by cables, or stuck at a workstation. Wi-Fi symbolizes the ability to transfer data from one source to the next via a wireless link. Any product that houses the radio technology 802.11, a standard that has received widespread adoption, is considered a wireless device. The standard was developed in 1997. Fathers of Wi-Fi With any popular invention or supposed novel idea controversy seems to always linger in the background. When we think of the printing press we think of Johannes Gutenberg, however roots of printing with movable type can be traced back 350 years......

Starbucks Introduces Wi-Fi

...service provider, to enable Starbucks’ customers the ability to drink their coffee and eat their food while using their laptops, PDAs and other devices to access the Internet (Henderson, 2001, pg. 66). This Wi-Fi capability also enabled Starbucks’ managers and employees the ability to run the business and their specific locations more efficiently and effectively. As of 2003, Starbucks reported that they already offered wireless Internet service in most of their stores within the United States and plan to offer Wi-Fi in 2,700 locations by the end of 2003 (Hartnett, 2003, pg. 62). Wi-Fi’s Value-Added Benefits Starbucks is seeking the opportunity to, “keep butts in seats for the opportunity to serve up a second cup of Joe.” (Powell, 2003, para. 3.) Attracting customers is one of the primary concerns for any business. Offering wireless Internet connections within their locations enables Starbucks to attract customers in another manner, rather than the direct coffee and snack avenue, while simultaneously keeping their customers in the locations longer than normal. Starbucks not only views the Wi-Fi introduction into their locations as a way to keep their customers coming in, but also as a way to operate their business more efficiently. Starbucks is utilizing the Wi-Fi capabilities to allow their employees, especially store managers, to access applications and databases to streamline hiring, sales, inventory handling and various other tasks to enable managers to work......

Voip as a Bew Trend

...VoIP as a New Trend Student Name University Name Professor Name 06/20/2010 There is a new trend that has taken the networking technology to the next level. It all started in the 90’s looking for a less expensive way to make phone calls across the world. Both residential and commercial customers have been looking for a cheaper way to make local and international calls. This new revolution is called Voice over Internet Protocol (VoIP). If I had to put this in plain terms, this technology allows voice traffic to be transmitted over the Internet. VoIP is a new application of Internet Protocols (IP) that enables the conversion of voice communications into data packets and then these packets are transmitted via an IP network such as the Internet. “VoIP services convert your voice into a digital signal that travels over the Internet”. (fcc.gov) Similar to using your analog phone system and going through a Public Switched Telephone Network (PSTN), now you will be using a digital phone and going through the Internet. All you need to get the ball rolling and to be part of this new trend is a decent Internet connection at home and you could say goodbye to that plain old analog telephone line forever. Most cable companies are offering service bundles that include cable television, Internet access and telephone services. These companies are transitioning from the telephone analog system to the VoIP systems. A lot of costumers are switching over to VoIP for the simple reason of......

Make Wi-Fi Faster

...Make a wireless network faster There are many ways to improve Wi-Fi network speed, such as placing the router in the center of the area you want it to cover, keeping the router away from metal objects that could block the signal, or making sure there aren’t too many other radio-enabled devices broadcasting on a 2.4GHz signal, which is standard for a lot of older routers. Some other suggestions: 1. Check your speed. Checking the speed of the connection will let you know for sure whether or not your system is within range of the speed the ISP promised. A speed test is easy to find online. SpeedTest.net and TestMy.net are good sites to test one’s broadband speed. 2. Change the channel. If you have an older router, and its signal is seeming weaker than it should be, you can try manually adjusting the broadcast channel to find one with less number of wireless routers competing for space. If your router is newer and automatically chooses which channel to broadcast from, then you won’t get too much use out of pinning your wireless down to a single channel. How to change the channel: First, go into the router’s graphical user interface (GUI), by typing the router/gateway address into the address bar in a browser window while your computer is connected to the router’s wired or wireless network. The router’s address is usually found on the router itself, in the instruction manual, or online if all else fails. If you have a D-Link router, you’ll type; if you......

Economic Analysis of Gogo’s in-Flight Wi-Fi

...Case Study: Economic Analysis of Gogo’s In-flight Wi-Fi November 2, 2015 Introduction Gogo pioneered and now dominates the in-flight Wi-Fi business, which allows passengers to access the Internet during their flights. In recent years, consumers have grown from anticipation to dislike towards Gogo’s services due to its steady increase in fees and rapid decrease in speed. Through a dynamic pricing strategy they hope to relieve congestion which indeed have effect, but will not last in the fierce competition of an oligopoly market structure. Unlike its monopolistic position before, Gogo now faces at least three companies—ViaSat, Global Eagle Entertainment, and Panasonic— swiftly eroding its market share with cheaper and faster in-flight Wi-Fi services using satellites instead of antennas. Gogo’s own next-generation technology 2Ku, to come online in 2016, uses satellites that hopefully would achieve better prices with higher speed. To analyze the market for in-flight Wi-Fi and the pricing strategies of Gogo, our paper will discuss five core areas:      The price elasticity of demand for Gogo’s service, and how it varies with price levels The market structure Gogo is operating in Its dynamic pricing How the demand for in-flight Wi-Fi has changed over time, technological changes over the past 15-20 years that has affected demand Technological factors that affect supply, how congestion affects pricing and our recommendation Price Elasticity of......

Unified Communication

...Unified Communication Platforms IT 200 Sheriah Hannemann 27 March 2016 Instructor: Wendy Chasser There are many options for a unified communication platform, choosing the right one for you will be based off of what you need it for and if it accomplishes everything you need it to. The five factor when looking into a unified platform are: Functionality, flexibility, architecture, security and usability. There are many platforms to choose from for instance Skype and or FaceTime are great options. Skype is an application that allows you to video chat, voice chat or text another person from anywhere in the world. Skype can also be used on any computer/laptop or your smart phone. Skype is a very good application to use if you're missing your family or friends or if you need to attend a conference call but are unable to travel. Skype always gives you clear and crisp video and voice so no matter how far apart you are from one another, you will be able to hear and see them. Skype has many "advanced" features to it too, one of the more interesting ones, in my opinion, is that you can call someones land line and speak with them while you are on Skype. You can also set up Skype Voice mails. Skype is kind of like a phone on your computer. Skype is a great application for either home use or office use. FaceTime is another option as you can use it on all apple products. FaceTime is not yet available in the android systems but I feel that it has a......

The Future of Super Wi-Fi

...The Future for Super Wi-Fi By Chris Riley What the heck is super Wi-Fi anyway? First let us explore the history of wireless communications. In 1747, Benjamin Franklin proposed that electricity could move through air. In 1819, Danish physicist Hans Christian Oersted noted that a compass needle moved in the presence of an electrical field. Michael Faraday demonstrated the first electromagnetic induction and built the first direct current generator in 1831. In 1865 and again in 1873, famed Scottish physicist James Clerk Maxwell published multiple papers regarding electromagnetics. Alexander Graham Bell and Charles Sumner Tainter invented the photophone in 1880. The photophone was a telephone that conducted audio conversations wirelessly over modulated light beams, which required a direct line of sight. In 1885 Thomas Edison used a vibrator magnet for induction transmission. In 1891 he filed a wireless patent for the signal system and method using inductance he applied to the Lehigh Valley Railroad system he established in 1888. In the meantime, Henrich Hertz demonstrated the existence of electromagnetic waves with an oscillator. Then came what is perhaps the most debated topic in wireless history, the invention of the radio. WiFi has easily been one of the most useful technologies of the past decade so many of our daily tasks and the devices we use rely on it, and it’s on the verge of getting a whole lot better. First, it's not as new as it might sound...

Compare Different Unified Communication Platform

...Compare Different Unified Communication Platforms Stefanie Bailey IT/200 June 6, 2016 Mark Damron Compare Different Unified Communication Platforms My team compared the different Unified communication platforms. Softphone- is a software program that allows you to make calls over the internet using a computer. VoIP- voice over IP is voice information over the internet that sends the voice information in a digital form rather than the traditional telephone network. Half Duplex- is a computer circuit allowing the transmission of signals in both directions but not at the same time. Full Duplex is when both parties communicate as one. It allows data transmission to more than one device. PBX working on premises within an enterprise that (private branch exchange) is a private networking and switching system operates with traditional telephone lines One of the examples my team discussed of Softphone was Magic Jack because it is a phone service that is ran through internet and not actually wired through hardwire equipment. An example of VoIP would be the phone line being connected through your cable modem vs. the traditional way it use to be wired through your home. A great example of Half Duplex is a walkie talkie because you can talk to each person back and forth, however you have to take turns speaking no two people can talk at the same time. An example of Full Duplex would be a three way call because everyone is communicating at one time as......

Future of Voip

...Future of VoIP Introduction If we are to considered ourselves as the business aiming at profit increase and progressing growth , thus delivering better quality services to our customers, we have to think about our operational cost and the ways of reducing it. One such way is the implementation of Voice over Internet Protocol ( VOIP ), also known as the internet telephony. VOIP has become more popular in recent years as companies need to cut costs and improve communication between increasingly mobile employees and increasingly global customers. The first Voice over Internet Protocol (VoIP) call was made back in 1995 between two PCs. Initially, this was just a technological novelty. However, by 1998, VoIP had already begun establishing itself as a low cost means of providing calls over long distances. It was estimated to carry about one percent of the US phone traffic. Thirteen years later, VoIP has managed to revolutionize the manner in which business and residential communications take place. Infonetics estimates that about 25 percent of the total international phone traffic is handled as VoIP. So what exactly is VoIP and how does it work? Let me give a few basics about VoIP. Many people have used a computer and a microphone to record a human voice or other sounds. The process involves sampling the sound that is heard by the computer at a very high rate (at least 8,000 times per second or more) and storing those "samples" in memory or in a file on the computer. Each...
