...Wi-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.

...ABSTRACT There are many trends in our IT industry. Here we are going to discuss about the emerging technology in IT (i.e.) Wi-Fi technology. Wi-Fi (wireless fidelity) is a way to connect to the internet without any wires or cumbersome cables. Wi-Fi technology uses a radio technology called 802.11 b for the wireless connectivity. 802.11 buses 2.4GHz of band frequency spectrum with a bandwidth of 11Mbps(802.11a-5GHz,54Mbps & 802.l1g-2,4GHz,54Mbps).In this paper we have discussed in detail about what Wi-Fi is and How does it work, what the hotspots are and how does the Wi-Fi technology has been implemented in these hotspots. The Wi-Fi technology finds its great utility in the device called Infinity Tele Smart patient-worn technology system, a full size patient monitor system, in the palm TX handheld device and also in many other medical types of equipment. It is also playing a major role in the Robotics. Though there exits many other wireless technologies such Bluetooth, Wi-Fi competes them with its high data transfer rate and the transmission of the data over a large distance. Though Wi-Fi is a very advantageous and a powerful technology, it is also posed to some defects during the transmission of the data. To say like, interference with the household devices like microwaves and it's also possible for hackers to use your access point to connect to the Internet. To overcome the above mentioned discrepancies, we have also discussed about the security measures...

Their different security features and known issues with wireless technology. As well as how business implement Wireless networks, the different hacking methods used against Wireless networks and its future technological uses. There are many different wireless standards ranging from 802.11b to the new 802.11ac standard. Many manufactures exist with their own unique features for both home and business use. Each Wireless network standard was set forth an agreed upon by the IEEE or Institute of Electrical and Electronics Engineers. “IEEE is the world's largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. IEEE and its members inspire a global community through IEEE's highly cited publications, conferences, technology standards, and professional and educational activities, ("About IEEE," 2014)”. The IEEE sets forth the standards for each 802.11 standard, starting with 802.11b, which is a “Wireless radio-frequency local area network. 802.11b, adopted Sept. 1999, operates at 11 Mbps in 2.4GHz band.

...Case Study 2: Wireless and Mobile Technology By Terry Boone Dr. Stevens CIS 500: Information Systems for Decision Making 5/24/2014 Wireless and mobile technologies have transformed our daily lives, and also made a huge impact on the business world. The definition of the terms wireless and mobile technologies are often used interchangeably; however, this is not the case. Wireless technology is the ability to communicate on the internet via devices without a wire. Mobile technology is the ability to communicate on the internet via wireless and over a wired connection. Mobile technology allow for a user to access the internet anywhere at any time; conversely, wireless technology is only limited to the broadcast area emanating from the router and modem combination. Businesses use wireless and mobile technologies to increase efficiency by saving money on installation costs freeing up funding to be used elsewhere. Businesses can use wireless technology to connect employees throughout building, but still be connected to important software that runs the businesses operations through portable devices. Cell phones, laptops, and tablets in conjunction with wireless technologies have created the possibility for employees to become more powerful. Smaller organizations must maximize the efficiency of workers, so they can compete. Small organizations must ensure that employees are always connected, in addition to not being tied down to a single location (Koose, n.d.). Smart phones...

...Eric W. Branch Assign 1 Argument EN1420 I recently read an article by Nancy Trejos in USA Today about an argument over whether or not access to the internet is considered community property. On October 3, 2014 Marriott International agreed to pay a fine of $600,000 as well as adhere to a three year Compliance Plan for illegally interfering and disabling Wi-Fi networks established by it’s customers. In addition to the fine and Compliance agreement, Marriott will also file progress reports to the FCC every three months. The investigation began after a March 2013 complaint from an individual attending a convention at the Marriott Opryland Hotel stating that the hotel was “jamming mobile hotspots so that you can’t use them in the convention space.” Marriott officials stated that they believed that having their employees block Wi-Fi signals and then charging customers to use the hotels plan at a cost of sometimes up to $1,000 was legal in their eyes. According to the official FCC news release this was in direct violation of Section 333 of the Federal Communications Act. Marriott argued that they did this in the best interest of their customers. A company statement from Marriott argued that “Marriott has a strong interest in ensuring that when our guests use our Wi-Fi service, they will be protected from rogue wireless hotspots that can cause degraded service, insidious cyber-attacks and identity theft.
