Imagine living in a world where smart phones and computers are non-existent. People are dependent on these technologies and wouldn’t be able to work efficiently without them. But what good are smart phones and computers if there was no internet? The internet is the most imperative, fundamental and ingenious invention known to the modern world. Technology has made it possible for people to connect to the network wirelessly. This growing trend of Wireless Local Area Networks, WLAN, are continually evolving following the development of new WLAN standards. The WLAN standard has evolved from the first WLAN standard 802.11 to the newest generation of Wi-Fi signaling, 802.11ac. The standard has changed as new technology made it possible for improvements in aspects such as higher bandwidth, reduced interference and overall better performance. The development and implementation of 802.11ac has prominently impacted the end user experience. 802.11ac could be beneficial for healthcare and education enterprises as well as home and business use. The fifth generation of WLAN standard, 802.11ac “Gigabit Wi-Fi standard”, has significantly improved upon the more popular 802.11n. 802.11ac is the new standard for wireless local area networks.
Wireless networking has proven to become a vital fragment in companies and homes. Wireless LANs has exemplified its advantage in mobility, productivity, convenience and deployment compared to wired LANs. The Institute of Electrical and Electronics Engineers, IEEE, has continually expanded upon the original 802.11 as the popularity of Wireless LANs grew. The new standard for WLAN, 802.11ac, came from a history of standards dating back from 1997. The benefits of Wireless LAN has continually propagated as new stan...

Wireless Local Area Networks are all around us. Businesses need WLAN in order to operate, Universities need Wi-Fi in order to provide students the media they need, and hospitals require a reliable network for their patient critical operations. The next generation of WLAN standard, 802.11ac, would make it possible for all enterprises accomplish their needs. The Institute of Electrical and Electronics Engineers persistently expanded the possibilities 802.11 could achieve. The standard 802.11ad would eventually be put in place to compliment 802.11ac. Engineers continue to draft and create new standards to make enterprises run smoother, support healthcare services and deliver media flawlessly to educational institutions. There are no limits to how 802.11 could grow and continue improving to accommodate the fast pace society we live in today.
Wireless Local Area Network (WLAN) is one of the most successful technologies in IEEE 802.XX standards family. WLAN provides free connectivity, mobility, and flexibility with a relatively low cost for users. The widespread use of WLAN technology in streaming videos and voice applications stimulated high bandwidth capacity for WLANs. Recently IEEE has announced latest WLAN standard 802.11ac. For 802.11ac to be effective, it requires minimum 80 MHz wide channel with optionally up to 160 MHz. The increase in bandwidth leads to problems like OBSS. OBSS problem occur when two or more BSSs operate in same channel and are close to hear each other. This is an undesirable situation where two or more BSSs compete for channel access and increase contention which ultimately degrades performance/efficiency of the WLAN system [1]. The problem was not critical with 802.11a/b/g/n where the channel bandwidth was reasonable. ...

Wireless is everywhere today, whether at home working from your WIFI network to work where you might be linked to 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 connected to wireless from the moment they leave their home till they get to work and then back. Wireless communication definitely provides an advantage over wired networks due to its mobility allowing users to connect from virtually anywhere, however because of this convenience they are also more physically exposed compared to wired networks because of how the data is transmitted given attackers a high number of access points to constantly attack. This also brings around the concern because of a large number of wireless networks constantly being put up most everyone is not going to recognize the importance of securing your network and how easily their data can and probably is being stolen. Think about living in an apartment complex or in a neighborhood and doi...

Wi-Fi facilitates ease of use and is getting increasingly popular with homes and businesses. Multiple Wi-Fi Access Points can be located in a given area. Wi-Fi security issues continue to be a problem, as the number of Access Points grows.
Today’s world is one where smartphones can be found in the pockets of nearly everybody that you may commonly encounter on the street, ranging from the average blue-collar worker to AARP cardholders, even children have been spotted typing furiously away at their screens. How is it possible to maintain high download speeds and smooth functioning when seemingly everyone is overloading the board all at once? The answer lies in technological advances in wireless communication. Researchers and developers have painstakingly spent hours trying to perfect their systems and provide a service that far exceeds the often-simplistic needs of their users. Nowadays one can order a pizza, check their bank balance and even showcase their report all from the palm of their hand.
WLAN (Wireless Local Area network) and its components: The task of developing a WLAN on commercial front possesses a greater challenge. Developing initial design, purchasing and installing components, managing and providing maintenance to the systems are the main basic parts of the WLAN. When we use WLAN on a commercial front then we may face the security and privacy concerns. The total area of that particular commercial area should be accessible. This is only possible with installing huge number of access points. The various components of the WLAN are
For mini project of this subject, I choose to analyze performance management of different Wi-Fi based on context Wi-Fi service provided in my house area which is SriPuteri WifiNet. To analyze the performance management, I have to identify the problem statement, scope and method to use. In Local Area Network (LAN), although multiple device such as PC, laptop, mobile phone and many more can connected to Wi-Fi but as the increasing of device used, the network can become slower because of data traffic congestion. To overcome the problem, it is essential to have a good Network Management plans.
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).
Networks: The author mentions three major obstacles. First is wireless network capacity. The ability of wireless networks to transfer higher amounts of data at greater speeds without being prone to noise and multipath interference is a real test [2]. Second is the range of wireless networks. The range is limited and does not span across large areas limiting the use of wireless technology. Third is the integration between wired and wireless technologies. The integration among the two technologies is tough, challenging and needs improvement. Networking is an important challenge to pervasive
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.

Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
