The most sparkling stars of wireless networking technology today is IEEE 802.11b.The 802.11b wireless networking has enjoyed a rapid increase in adoption in enterprise settings and in educational and institutional networks. More recently, particularly in the past year as adapter and access point prices have lowered dramatically, 802.11b wireless network products have been making inroads into home and SOHO applications. Initially, the demand for 802.11b in the home was driven by people who ...

Stephen Kern, a professor of history at The Ohio State University, wrote the chapter “Wireless
Wireless is a methodical account of the early development of wireless telegraphy and the inventors who made it possible. Sungook Hong examines several early significant inventions, including Hertzian waves and optics, the galvanometer, transatlantic signaling, Marconi's secret-box, Fleming's air-blast key and double transformation system, Lodge's syntonic transmitter and receiver, the Edison effect, the thermionic valve, and the audion and continuous wave. Wireless fills the gap created by Hugh Aitken, who described at length the early development of wireless communication, but who did not attempt "to probe the substance and context of scientific and engineering practice in the early years of wireless" (p. x). Sungook Hong seeks to fill this gap by offering an exhaustive analysis of the theoretical and experimental engineering and scientific practices of the early days of wireless; by examining the borderland between science and technology; depicting the transformation of scientific effects into technological artifacts; and showing how the race for scientific and engineering accomplishment fuels the politic of the corporate institution. While the author succeeds in fulfilling these goals, the thesis, it seems, is to affirm Guglielmo Marconi's place in history as the father of wireless telegraphy.
The 802 committee and the OSI model both relate to one another. The OSI model shows how the layers of the internet are able to communicate and function with each other. While the 802 committee will add onto that by showing how network protocols should function. With that being said there are numerous working groups under the 802 committee however the one that I will be writing about is the 802.2 or the logical link control (LLC). The logical link control is in the 2nd layer (data-link) of the OSI model. The purpose of this protocol is flow and error control along with multiplexing and demultiplexing. How multiplexing works is by getting multiple data streams and combining them into one shared stream. This is mainly seen in the common forms
There multiple LAN standards because there might be wide range of data rate and transmission that might need to support. For that reason there are a set of standard that are developed by IEEE 802 committee which are accepted and used by most of the product in the market today. Some may use the standard for Token ring, Ethernet and Wireless.

You have probably taken advantage of Wi-Fi access when traveling, at airports, in your hotel room, shopping, enjoying a latte at your favorite coffee shop or even waiting for your doctor to see you. In today’s world, Wi-Fi is an important feature whether you are in the hospitality industry, (free, high speed, in-room Internet access ranks as the most desired guest-room amenity), at an event (free Wi-Fi affects the choice of venue ), or in an office/hotel lobby, bar, restaurant or conference room. As a business owner or IT manager selecting the right wireless solution can have either an adverse effect on business or be a highly beneficial
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.

Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing Internet wirelessly at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router. By transmitting signals at 2.4 or 5 GHz it allows the waves to transmit more data at a faster rate. Typical Wi-Fi standards are 802.11a, b, g, n, or ac and they can switch up the frequency depending on the model (Brain). Families can create their own wireless network that can be shared between family members without the use of hooking all their devices up to the modem and can also protect their home network from potential hackers with the use of a TKIP or AES encryption. Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires(Cox).
LANs systems can be defined and connected in many different ways. This is the reason for the standardization for every one can have a common ground to start from. “The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographic area such as a single office building, warehouse, or a campus. The IEEE 802 LAN is a shared medium peer-to-peer communications network that broadcasts information for all stations to receive. As a consequence, it does not inherently provide privacy. The LAN enables stations to communicate directly using a common physical medium on a point-to-point basis without any intermediate switching node being required. There is always need for an access sublayer in order to arbitrate to access to the shared medium. The network is generally owned, used, and operated by a single organization. This is in contrast to Wide Area Networks (WANs) that interconnect communication facilities in different parts of a country or are used as a public utility. These LANs are also different from networks, such as backplane buses, that are optimized for the interconnection of devices on a desk top or components within a single piece of equipment.”(IEEE 802 Standard 1990) That is the standard definition for LANs by Institute of Electrical and Electronics Engineer committee 802. They are the committee used to set the standard in workmanship and operations for technicians that set-up and perform maintenance on LANs systems. And through all the technical words what they are trying to say is a LAN is a small area network that distributes information among computer in a small work environment unlike WANs that distribute information across global areas.
Barcodes are used everywhere around us. They are used to track products through shipment, track products at a store and speed up and enhance the checkout process, as well as allowing faster access to information. Barcodes began to be used heavily in the 1970’s. This began a great movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. However, just like all technologies, barcodes have been enhanced many times over and are being replaced by better, more efficient systems (Bonsor).
Wireless is everywhere today whether at home working from your WIFI network to work where you might be linked a wireless network or even through your phone through a 3G or 4G network to connecting to an open wireless networks. As you can see for the most part people are connecting to wireless from the moment they leave their home till they get to work and then back. While wireless comm...
Wireless communication has encouraged the practice of optimizing performance in wireless networks to achieve higher data rates and network coverage for the end user. Such strategies and methods will be examined to verify their validity and to introduce future solutions to the limitations of wireless communication systems. Wireless communication performance is affected by channel fading, path loss, and interference. There are several techniques that can be used to avoid signal degradation. At short distances, a transmitter and receiver pair is capable of achieving a quality connection. However, relay networks have become a popular strategy for transmitters and receivers that have been separated by large distances or large obstructions in the path. Relays are used to retransmit the signal with or without encoding it again. Cooperative communication extends coverage and reduces transmission power by utilizing spatial diversity. Distributed Coding is a cooperative technique that allows multiple antennas to work together to transmit information. The specifications for these different networks can be a difficult task. There are several relay configurations and trade-offs. The present design process for relay networks is constrained to the drawbacks of the wireless channel. Strategies using MIMO (multiple input-multiple output) overcome many of the inherent problems with wireless transmission and have become widely popular. Research will expound on the advantages of relay systems, MIMO, and other selected strategies that optimize performance in a wireless network.
During the increase in popularity of radio, Arthur Edwin Kennelly said (1926) "through radio I look forward to a United States of the World. Radio is standardizing the peoples of the Earth, English will become the universal language because it is predominantly the language of the ether. The most important aspect of radio is its sociological influence." Kennelly was foreseeing the potential power and impact that radio would soon come to have. By the late twenties, we would see radio become quite the sensation in the household, and this sensation would continue to prosper even through the Great Depression with aid of soap operas and popular programs such as the Lone Ranger. Radio would see a decrease in popularity during the rise of the television. Eventually, radio would find itself a niche in the media market, allowing it to continue to prosper. This would be due to the help of Frequency Modulation radio broadcasting and localization. Radio stations were now able to offer more local content than radio, touching on local news, weather, and advertisements for local businesses all at a higher sound quality. That joined with a symbiotic relationship with the recording industry and the start of formatted radio programs, the two industries were set to last for almost another fifty years (Adams, n.d.).
One among the successes of the computer industry in the last few years is the innovation of Wi-Fi, a short-range wireless broadband technology, which marked a rare bright spot in a bubble-battered market. Wi-Fi is a facility that allows computers, smartphones or other devices to connect to the internet or communicate with one another wirelessly within a particular area (Hamblen and Hofstadter, 2008). Wi-Fi access is available in a growing number of coffee shops, restaurants and hotels, too. Homes, offices, colleges and schools around the world have installed Wi-Fi equipment to blanket their premises with wireless access to the internet. Wi-Fi on campus gives off an effective college education
