Wireless Fidelity
In the last few years the world has undergone a tremendous and unprecedented technological change with the attack of the Information Technology revolution. Earlier it was e-mail that changed the way people communicate, and then online shopping became the order of the day, gradually online banking caught up and the list goes on and on. The new trend, Wi-Fi, or Wireless Fidelity, allows you to connect to the Internet from your couch at home, a bed in a hotel room or at school, all without wires. As author Harold Davis nicely puts, “Wi-Fi is a wireless technology just like a mobile phone and Wi-Fi enabled computers send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi certification means that you will be able to connect anywhere there are other Wi-Fi CERTIFIED products — whether you are at home, the office, school and other public areas equipped with a Wi-Fi Access Point device” (35). Customers with the capability to tap into wireless Internet networks at certain universities and Starbucks coffee shops in US will soon be able to browse the Web in a very inexpensive way using the wireless internet technology
Wi-Fi WLAN use radio technologies called IEEE 802.11b or 802.11a to provide secure, reliable, fast wireless connectivity. Michael Galagher notes that, “A Wi-Fi WLAN can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet)” (120). Wi-Fi WLANs operate in the unlicensed 2.4 and 5 GHz radio bands, with an 11 Mbps (802.11b) or 54 Mbps (802.11a) data rate or with products that contain both bands (dual band), so they can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many networked environments.
Competition has already driven down the costs of deploying 802.11b networks which can now be deployed by businesses to give their employees mobility within the business. Home users can buy 802.11b kit to extend their DSL or cable broadband Internet access wirelessly to the entire house. James LaRocca points out that, “In universities and schools a wireless network can allow computers to be integrated more effectively into teaching as classes no longer need to be held in computer lab” (48).

...The master key also serves as a password by which users can be authenticated and granted network access.
WPA was designed to be a software upgrade to WEP, so most existing wireless devices should be upgradeable to WPA via a firmware (define) update. In order to take advantage of WPA, all network devices like access points and clients must be upgraded.
The first WPA-enabled products are expected in the early Spring of 2003, and upgrades for existing products should be available at around the same time or shortly thereafter.
For Wi-Fi to really take off in homes, its needs to capture the public imagination and make the initial equipment costs seem even more trivial – similar to when TV sets were drastically reduced in price . "Wi-Fi is a key step for home networking, but it still doesn't solve issues of developing home entertainment," agrees Roland Berger's Kintz.
That's probably true. But coming up with an attention grabber doesn't seem so impossible with Intel and Microsoft already pouring millions of dollars into Wi-Fi technologies and major carriers such as VoiceStream and AT&T figuring out how to make the technology work for them.

Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
Ankle sprains are one of the most common musculoskeletal injuries and are especially relevant at all level of sport.1 Of all sports, the incidence of ankle sprain is higher in volleyball considering its non-contact nature.2 The most common ankle sprain occurs on the lateral or outside part of the ankle.3 Reports estimate that ankle sprains account for approximately 24% to 54% of all sport-related injuries and 23,000 persons get them per day in the United States.4
Thanksgiving Day is a day of family, food, and giving thanks for the blessings in life and yet some people believe Thanksgiving to be a prep day for Black Friday, the biggest shopping day of the year. The focus of Thanksgiving shifted from family bonding to incessant shopping. This trend of taking away from the hours of Thanksgiving in order to shop is enraging. It steals away from family time for the shoppers and the employees. Employers threaten workers that if they do not work on that certain holiday, they will be fired. Black Friday should be kept to Friday instead of moving in on my family time. The whole culture of Black Friday has become repugnant and unnecessary.
Doing research during the lesser holidays like Mother's day would be beneficial. This can be accomplished through data collection and data mining through a data warehouse and an analysis of the data that can recognize spending trends for customers and target those customers as valued customers and prioritized as such. Implementing this method would alleviate most of the surge day pressure. The data can be analyzed in conjunction with statistics to get an idea of when demand will increase and when to start capacity planning to use as a contingency plan.
James Baldwin’s works were influenced by the times in which he lived, as an African American writer he strove for equality and used his pen to work for civil rights through elements of his childhood among other aspects.
...verything in the consumer’s home. Many techies would love to have a box that stores security video, TV, internet, photos and music. Make that Wi-fi and Bluetooth enabled so that they can access it anywhere in the world and you could be on to something bigger.
The Friday after Thanksgiving is everything from a bargain hunter’s dream come true to a husband’s worst nightmare. Since the early to mid-sixties it was been given the name “Black Friday.” Black Friday is day where stores around the country open their doors early to welcome the start of the Christmas shopping season. This is the day if you get to the mall by five a.m., you are late and will not find a parking place. It is the same day where you start off by being cussed by a pregnant woman, and end by being beat-up by an elderly lady resembling your grandmother. Much is to be said for the day, and for those whom brave mess.
Access (WiMax) is very important to Motorola. WiMax is an Institute of Electrical and Electronics Engineers (IEEE) standard designated 802.16e-2005 (mobile wire-less). With WiMax cell phones will no longer be tied to cellular networks. WiMax has the potential to replace a number of existing telecommunications infrastructures (WiMax, 2007).
The propose research will address a problem confronting many two year institutions in the present-day (i.e. how to best plan, design, and implement WLAN technologies). While WLAN technologies offer the benefits of mobility, reduced installation time, and decreased cost, many challenges must be met by institutions deploying them (Geier, 2005). These issues are related to security, speed, interoperability, and equipment selection, ease of use, reliability, signal interference, installation, and health risks.
Ultimately the end users turn out to be the weak link in the security chain as they ignore the latest security trends and install outdated devices that do not support the latest security features. An example would be that of an outdated wireless router that does not support WPA encryption. By proposing a simple solution that lets the users configure their wireless access points for best possible security, the problem can be nipped in the bud.
The Digital Video Recorder used in modern entertainment systems can now be replaced with an easy to use streaming video devices. As the online video libraries grow to include more content, eventually streaming set top boxes will provide this functionality, without the need to schedule recordings or manage space used by previous recordings. One additional advantage, often referred to as TV Anywhere, allows viewing of online content from a variety of devices, as long as an Internet connection is available. Now the real motivation that drives many Americans to consider these alternative options is money.
Recent studies on parental involvement in education have found that there are many benefits for both the student and the adult when parents become involved in their children’s education. Without parent support, it is very difficult for a child to be motivated. From what I have seen growing up, only a small percentage of students are self-motivated, so it is absolutely vital that parents assist in the motivation process. I found this table to be particularly interesting and important.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
...ved way for many recent technology advancements. Media is ever changing and with one invention becoming inexistent, another is born. Many of the earlier communications inventions have advanced and developed to fit the needs of society today. Although one would think that all technology becomes obsolete when another advancement is made, the truth is that almost nothing disappears; it just advances to fit the technology of the time period. The Internet has been integrated on almost every aspect of technology today and continues to grow by the second. I’ve always thought about whether or not someone could create something that is larger than the Internet, a new technology that has been unheard of until its release. With new technology, anything is possible.
