Wireless Technologies : 802.11 Vs. Mobile Telephony

There are 9 IEEE 802.11 services in total which can be classified into to categories:

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital audio players connected using the Wi-Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors and a greater range outside.

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

2. What are the three areas defined for the IEEE 802.11 standard? Physical Layer (PHY): The method of transmitting the data, which may be either RF or infrared (although infrared is rarely used.)

802.11 WLANs use CSMA/CA, the devices use a four-way handshake to gain access to the airwaves to ensure collision avoidance, and also to know about hidden nodes from different wireless standard.

The invention of wifi didn't start as, well, wifi. It started with a woman named Hedy Lamar. She was born Jewish during WW2. She fled to America where she became the most beautiful actress ever. People saw her only for her looks, not her brains. She invented many things, stupid things, like a new Kleenex box. But, one day, she thought that if pianos could hop from note to note, so could radios from frequency to frequency. So she and a partner invented Frequency Hopping. Her thought process was if radios hopped from signal to signal, it couldn't be jammed or hacked into. It was called, Frequency Hopping. It was presented to the Navy, and they turned it down. Lamar got a patent for it, but in years later sold it off to the Navy. She watched it

Known to many as Wi-Fi, its actual name is “Wireless Fidelity.” Wi-Fi is considered to be what correlates to wireless networking technology of which allows computers amongst other devices to communicate over a wireless signal. The designation 802.11

Evaluate and select a WLAN architecture. Wired Ethernet frames are converted to wireless RF signals through access points (APs). The two main access points are autonomous APs and lightweight APs.

As you probably realized, you use wifi everyday for multiple reasons. What you probably didn't know was how wifi came about. Many years ago, a lady named Hedy Lamar befriended a Hollywood composer named George Antheil. Together, they realized if a player piano could jump from note to note, so could a radio signal. Hedy proposed the idea to the Navy to torpedo German U-Boats in the Atlantic, but she was turned down and told to try and raise money instead. Throughout the years, Lamar's career started to slowly decline as others stole her idea of frequency hopping. In the end, Hedy earned no money from her idea, and her beauty was much more noticed than her brains.

“IEEE 802 subdivides the data link layer into sublayers, namely the logical link control (LLC) and media access control (MAC) layers, which provide protocol multiplexing and a multi-access mechanism, respectively. IEEE 802 is comprised of standards with separate working groups that regulate different communication networks, including IEEE 802.1, 802.3, 802.11 and 802.15.” (Technopedia, 2014).

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Wi-Fi can be found anywhere in this day in age, you can walk into almost any establishment and you’ll be sure to find their Wi-Fi, accessible from anywhere within their spaces. Each data packet being transmitted through the air, whether containing private, sensitive or insensitive information, is available for an attacker to capture. To fight against this, there have been some standards that have come out through the years to guard and protect data, such as WPA. All standards have been created to replace the preceding one due to vulnerabilities found in the engineering of them. Still to this day, not every standard is fully secure, attackers still find

The world of technology as we know it is now changing drastically. As the years progress new technology will replace the old. Individuals want faster services that are reliable. Wireless technology is going to be really important to have. It is already important in both the home and office sense. Wireless networks are already starting to replace Wired Networks. Nobody wants to have cables in their homes and offices anymore. The reason is simple and to the point: there isn’t a point to having long cables laying on the floor or having to make holes to push the cables in walls and through walls. The things that individuals and companies need to know is that Wireless Networks are catching up. The new technology that is coming out will make having a wireless network better than having a wired network. This will make having a wireless network a better choice to have than a wired network.

Wi-Fi is one of the greatest connective technologies available to us today. Wi-Fi uses radio waves - just like cellular phones, TV and radio - to create reliable high-speed connections between computers, printers, gaming devices, cameras phones and home entertainment systems. It is not a secret that wireless technology has become the model for entertainment, communication and education all over the world today. Now wireless technologies are very important for us so that we use them in an immense way. Many people all over the world use Wi-Fi in their homes to communicate to anyone with Wi-Fi connected devices. Schools, businesses, organizations use Wi-Fi to maintain and improve their quality and productivity. Students use Wi-Fi to learn, research and submit their homework. Workers use Wi-Fi to stay connect with other workers at work and have better communication with each other. Family members, friends use Wi-Fi to keep in touch and stay connected with each other. Wireless communication changes the way people interact and live their daily lives. There is no wonder why Wi-Fi is necessary for everyday life.
