...Wi-FiFrom Wikipedia, the free encyclopediaJump to: navigation, search For the radio station, see WIFI (AM). Wi-Fi logoWi-Fi ( /ˈwaɪfaɪ/, also spelled Wifi or WiFi) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards".[1] However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". A device that can use Wi-Fi (such as a personal computer, video game console, smartphone, tablet, or digital audio player) can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Hotspot coverage can comprise an area as small as a single room with walls that block radio waves or as large as many square miles — this is achieved by using multiple overlapping access points. "Wi-Fi" is a trademark of the Wi-Fi Alliance and the brand name for products using the IEEE 802.11 family of standards. Only Wi-Fi products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" designation and trademark. Wi-Fi has had a checkered security...

...Wireless Fidelity, or Wi-Fi, exploding in popularity, companies and even some whole localities are increasingly providing access to the public. Due to its popularity, varieties of businesses are exploring their options to stay relevant and attract customers. Airports, train stations, grocery stores and other public locations are offering free Wi-Fi in hopes to lure the consumer to purchase their products. Free public Wi-Fi facilitates a lengthier customer relationship and offers a competitive advantage against other local coffee shops offering the same consumables. The accessibility that retail companies have offered to their customers allows for easy and convenient access to the internet. Background Information Wi-Fi is radio-wave technology known as IEEE 802.11b. Wi-Fi has an inexpensive installation and runs with speeds up to 11Mbps. An existing local area network, LAN, needs to exist to install wireless access points. The advantages are the mobility it allows, ability for multiple devices to quickly access with or without authenticating, higher speeds than wired access, and installation costs. The disadvantages include the need for multiple wireless access points to increase signal strength in large areas, narrow area of space that the wireless signal reaches, connection hiccups and the weak security points of having a public network. There is currently minimal security offered directly by the internet provider. Literature Findings Current State Wi-Fi is still currently...

...Information Security Article Evaluation Nelson Okubasu CMGT/441 12/3/2014 MARJORIE MARQUE Can We Sniff WI-Fi?: Implications of Joffe v. Google Google collected information between 2007 and 2010 both in us and oversees. In 2010 a law suit was filed against google for violating the federal wiretap act. Among the first of the cases to rule on intercepting unsecured Wi-Fi communications. As of today our society has become so dependent on using Wi-Fi communications for various aspects of our lives, there is a parallel expectation of privacy. At the same time there are so many people or users out there who don’t understand how Wi-Fi technology works, if their information is secure, whether there privacy is violated or if the government has the right law in place to protect them. The fact that users do not fully understand Wi-Fi technology and the shortcomings of current security mechanisms is not a justification to violate their privacy, but instead to call on the government to enact or amend the Federal Wiretap Act (FWA) to reflect their reasonable expectations. Clear statutory protections will allow for the continued progression of Wi-Fi technology. Society’s dependency on Wi-Fi networks and public hotspots both economically and personally requires expansion of the FWA to ensure national uniformity. Essentially, the court found that even though Wi-Fi networks do transmit data using radio waves, the uses of Wi-Fi technology...

...Evil Twin Wi-Fi Attacks NT1110: Computer Structure and Logic October 23, 2013 Abstract What is the “Evil Twin”? Evil Twin is a type of Wi-Fi attack, it is a home-made wireless access point that masquerades as a legitimate hot spot with a very strong signal in efforts to gather personal or corporate information. With this, the overall goal of this report is to educate the public on how to protect themselves. Additionally in this disadvantages and advantages will be discussed along with the effects on consumers and the future. According to Dr. Phil Nobles, a wireless Internet and cybercrime expert at Cranfield University, said: this is how the evil twin works. "So-called 'evil twin' hotspots present a hidden danger for Web users. In essence, users think they've logged on to a wireless hotspot connection when in fact they've been tricked to connect to the attacker's unauthorized base station. The latter jams the connection to a legitimate base station by sending a stronger signal within close proximity to the wireless client -- thereby turning itself into an 'evil twin. Cybercriminals don't have to be that clever to carry out such an attack. Because wireless networks are based on radio signals they can be easily detected by unauthorized users tuning into the same frequency."

Wireless network trends are now offering new technology such as cloud computing and simply being able to work from anywhere you want. As you read on you will understand the benefits of wireless technology in our personal lives and in work situations. A Look at Wireless Networking Many organizations such as universities, retail centers and your own office depend on the ability to share information in an efficient and useful way. Nowadays networks are an integral part of almost every business and in your own personal life. There are two options for setting up a network — wired and wireless. A wired network uses cables to connect to a computer and a wireless network uses radio frequencies to connect to a computer. The components required to set up a wired or wireless network are somewhat similar with a wireless network needing a few additional pieces. Wireless networks are allowing individuals and businesses to become more mobile. For example, people are able to work from home these days and can have a better work-life balance. Businesses such as Starbucks, Tim Horton’s and McDonalds now all have free wireless access trying to add value to their customer’s experience.
