...display to Apex what they can do to bring their company to enjoy the modern conveniences of a wireless network. This deployment plan will cover Team B’s recommendations based off of the site survey provided by Apex. We will discuss our recommended wireless network type. The access point layout and how these points will be managed. We will go over the foreseen obstacles and what our plan is to overcome these obstacles. Finally, we will go over the security policy that should be implemented to keep Apex as secure with our wireless network as they are with their current wired network. IEEE Network Type Apex Designs has asked our company to design a wireless network for their business. This network will consist of several different pieces of hardware that all will work together to meet Apex’s needs. To ensure that the new network is operational, special considerations must be made as to which IEEE network standard to be used. Since Apex Designs is a business that has a preexisting network installed, the new network must be compatible with the legacy systems already in use. Failure to meet this requirement would cause major interruptions in work flow, thus hindering our joint goal of enhancing Apex Designs productivity. Our proposed network will also allow current and future technology connectivity. In order to meet these requirements, the use of dual band access points will be installed at strategic locations to allow maximum coverage. The access points will use the 802.11ac...

...IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, VOL. 18, NO. 3, MARCH 2000 535 Performance Analysis of the IEEE 802.11 Distributed Coordination Function Giuseppe Bianchi Abstract—Recently, the IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSMA/CA) scheme with binary slotted exponential backoff. This paper provides a simple, but nevertheless extremely accurate, analytical model to compute the 802.11 DCF throughput, in the assumption of finite number of terminals and ideal channel conditions. The proposed analysis applies to both the packet transmission schemes employed by DCF, namely, the basic access and the RTS/CTS access mechanisms. In addition, it also applies to a combination of the two schemes, in which packets longer than a given threshold are transmitted according to the RTS/CTS mechanism. By means of the proposed model, in this paper we provide an extensive throughput performance evaluation of both access mechanisms of the 802.11 protocol. Index Terms—802.11, collision avoidance, CSMA, performance evaluation. I. INTRODUCTION N recent years, much interest has been involved in the design of wireless networks for local area communication [1], [2]. Study group 802.11 was formed under IEEE Project 802 to recommend an international standard for Wireless Local...

...wireless applications and systems are widely adopted. Numerous organizations have already installed or are busy in installing “wireless local area networks” (WLANs). These networks, based on the IEEE 802.11 standard, are very easy to deploy and inexpensive. Wi-Fi allows LANs to be deployed without cabling for client devices, typically reducing the costs of network deployment and expansion. As of 2007 wireless network adapters are built into most modern laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in ever more devices. Wi-Fi has become widespread in corporate infrastructures, which also helps with the deployment of RFID technology that can piggyback on Wi-Fi. WiFi is a global set of standards, unlike mobile telephones, any standard Wi-Fi device will work anywhere in the world. Other important trends in wireless adoptions are including the introduction of wireless email with devices such as the Blackberry and The Palm VII, rampant digital cell phone use, including the use of short message service (SMWS), and the advent of Bluetooth devices. But the risks associated with the adoption of wireless networking are only now coming to light. A number of impressive attacks are possible and have been heavily publicized, especially in the IEEE 802.11b area. As far as base technology is concerned, wireless security appears to be following the usual “penetrate and path” route. Early wireless security focused almost exclusively on cryptography...

...The Evolution of Wi-Fi Charles Williams Albert Acuna ISSC340 American Military University Abstract From the creation of the IEEE standard in 1997 to current times Wi-Fi has evolved dramatically over the years. An idea to provide connectivity to devices with the absence of cables was adopted globally. Each year brings about new ways of utilizing wireless technology. This study aims to cover Wi-Fi from inception to present day and prospects for the future. The Evolution of Wi-Fi What exactly is Wi-Fi? A popular misconception is that Wi-Fi stands for “wireless fidelity”, however, it can be described as, a technology that uses radio waves to provide internet and network connectivity. The Wi-Fi Alliance, a non-profit organization founded by six companies in 1999, defines Wi-Fi simply as “connectivity”, connectivity in a way that provides freedom and the ability to move about without being tethered by cables, or stuck at a workstation. Wi-Fi symbolizes the ability to transfer data from one source to the next via a wireless link. Any product that houses the radio technology 802.11, a standard that has received widespread adoption, is considered a wireless device. The standard was developed in 1997. Fathers of Wi-Fi With any popular invention or supposed novel idea controversy seems to always linger in the background. When we think of the printing press we think of Johannes Gutenberg, however roots of printing with movable type can be traced back 350 years before...

...communicate with the network through a radio path vice a cable. The device that contains the radio and connects to the wired network is called the “Access Point”. Each client that communicates with the access point must have a wireless PCMCIA card. Once both devices communicate via radio transmission, network access can begin. Each client is configured to communicate with a single access point. A client can move from one access point to another. Roaming from access point to access point (cell to cell), similar to cellular telephone technology, is possible. Technology Discussion There are three wireless technology standards on the market today: Bluetooth, 802.11b, and 802.11a. A new standard, 802.11g, was recently approved by IEEE and products using this technology are expected to be released later this year (3Q). Bluetooth was the first wireless technology to the market. It operates at a frequency of 2.4 GHz (ISM band) using the Frequency Hopping Spread Spectrum (FHSS) modulation method. Bluetooth can transmit data at 700 Kbps at a range of 300 feet indoors. It was primarily intended for “device-to-device” communication as opposed to wireless networking,...

...One of the first items to clear up about this topic is when talking about wireless communications we are just not talking about wireless computers networks. Wireless communications also covers wireless phone networks as well as our wireless computer networks. While writing this paper I will try to keep it on just the wireless computer networks, but you will have to keep in mind that this all was started with the telephone and branched out toward computers and other handheld devices. Me like everyone else probably had never really look at wireless as a very vast network which started in 1876 when the phone was invented by Alexander Graham. In 1877, Charles Williams of Somerville Ma had the first private telephone was installed in the home. Four years later over 47,850 telephones were in use in the U.S. (Fowler, 2009). This was the start of the evolution of Wi-Fi, Guglielmo Marconi, an Italian inventor took it a step closer nine years later, and he proved the feasibility of radio communications by sending and receiving the first radio signal. Then in 1869, the first wireless signal across the English Channel was flasher by Marconi. (Fowler, 2009) This should not be confused with the Birth of Telecommunication as some people have linked Telecommunication with wireless communications as John M Shea, an associate Professor of electrical and Computer Engineering from the University of Florida did in an article were he stated in “The History of Wireless Communications” that...

...System Architecture 1. Define the term system architecture. Define the term scalability, and explain why it is important to consider scalability in system design. * System architecture translates the logical design of an information system into a physical structure that includes hardware, software, network support, and processing methods. Scalability is the measure of a system’s ability to expand, change, or downsize easily to meet the changing needs of a business enterprise. Scalability is especially important in implementing systems that are volume-related, such as transaction processing systems. 2. When selecting an architecture, what items should a systems analyst consider as part of the overall design checklist? * Before selecting a system architecture, the analyst must consider the following issues: * Enterprise resource planning (ERP) * Initial cost and (TCO) * Scalability * Web integration * Legacy system interface requirements * Processing options * Security issues 3. What is enterprise resource planning (ERP) and why is it important? What is supply chain management? * Enterprise resource planning (ERP) defines a specific architecture, including standards for data, processing, network, and user interface design. It is important because it describes a specific hardware and software environment that ensures hardware connectivity and easyintegration of future applications, including in-house software and commercial...

...Practical WLAN security Abstract This report covers the basics security standards in today’s wireless networks, how they work, existing flaws and vulnerability’s. We will go trough the basic architecture of 802.11, the security it provides like WEP, WPA and WPA2. Further more we will go trough some practical experiment exploiting the flaws described in the article. The result of our practical experiments show upon how easy it is to break encryptions and deploying Evil twins, even with very little understanding of the security structure. 2.1 802.11 Standards The architecture of the wireless LANs is specified by the 802.11 standard created by IEEE [1]. There are a few versions of the standard with differences in frequency and speed. Briefly these are a few of the current standards 802.11 (1997): 2.4Ghz, 2Mbps 802.11a (1999): 5Ghz, 54Mbps 802.11b (1999): 2.4Ghz, 11Mbps 802.11g (2003): 2.4Ghz, 54Mbps Even when things like speed and frequency differ, most things are the same as the original 802.11 standard. They all are using the same medium access protocol, CSMA/CS and have features for increasing range by the cost of speed. They also support the two connection modes of ad-hoc and infrastructure, but since this reports is about practical WLAN security we'll not go any further in on that and just care about the infrastructure mode. 1.
