Overview

A wireless Local Area Network (LAN) is a moderate to high-speed flexible data communications system implemented as an extension to, or as an alternative for, a wired Local Area Network (Kolawole, 2014). In wireless LAN transmission making use of radio frequency to communicate over the air eliminates or at least minimizes the use of physically wired networks. From the beginning, IEEE 802.11 was designed to look and feel like IEEE 802 wired networks to include supporting all of the protocols and LAN management tools that operate on a wired LAN (O 'Hara & Petrick, 2005). The major differences in a wireless LAN and a wired LAN is of course that there are no wires (air link) and the mobility of the solution.

What makes a wireless LAN such a convenient solution is the flexibility, scalability, and the simplicity of installation. A wireless LAN has the flexibility of being installed where wires cannot, without ever having to penetrate walls or barriers that would otherwise pose expensive solutions. Scalability means not only the choice of varied topologies but also the ease of changes that may need to be made to the configuration of the LAN. Simplicity in installation means that a LAN can be installed without the need or expense of pulling wires. It also means not having to purchase or install additional devices when connecting additional or multiple users.

The flexibility, mobility, and ease of installation has made the use of wireless LANs very attractive to organizations like hospitals, universities, and businesses that want the ease of connecting wirelessly. However the understanding of wireless LANs has also extended its interest to home users. Wireless LANS are now the preferred method of connectivity for ho...

    Segmenting the wireless network from the wired network though, is not only a trust issue, wireless networks suffer from many attacks such as Denial of Service caused by interference. The access point that will provide wireless access will be connected to a wired switch, however the separation of the wireless network is proposed to be done with the use of virtual LANs. VLANs will separate the network to two logical networks operating on the same physical network. This separation will enchant network’s security as the main network will be inaccessible from customers as well as it will not be affected if the wireless network is facing issues. The AP must be using Wi-Fi Protected Access 2 (WPA2) security protocol that has advanced encryption standards comparing to

    Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.

    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.

    Abstarct- In this paper microstrip stacked patch antenna with 10mm air gap using aperture coupling technique at frequency of 5.8 GHz has been discussed. Microstrip antennas suffer from a biggest drawback of narrow bandwidth and this can be improved by a technique called aperture coupling and further by stacking of antennas without increase in surface area of antenna. Without stacking bandwidth comes out to be 310 MHz and with stacking the bandwidth increases to 440 MHz. The airgap of 10mm is used between the two patches. The gain and directivity has also been increased. The bandwidth has been increased upto 42 % in this design. The application of this design is in WLAN and WIMAX. The simulation is done using CST 2010 software.

    Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

    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.
