A Survey On Wireless Networks

An access point is a hardware device or configured node on a local area network (LAN) that allows wireless capable devices and wired networks to connect through a wireless standard, including Wi-Fi or Bluetooth.

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

A networking framework in which devices communicated with each other by first going through an Access Point (AP). In infrastructure mode wireless devices can communicate with each other or can communicate with a wired network. With one AP is connected to wired network and a set of wireless stations it is referred to as a Basic Service Set (BSS). An extended service set (ESS) is a set of two or more BSSs that from a single sub network. Most corporate wireless LAN operates in infrastructure mode because they require access to the wireless LAN in order to use services such as file services or printers. A cellular network or mobile network is a wireless infrastructure base network distributed over land areas called cells.

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

Ad hoc networks are suited for use in situations where infrastructure is either not available

3. What is an ad hoc network? In this network, the wireless clients (stations) communicate directly with each

Local area network (LAN) is a wireless network that is mostly used in a work place or small building. To be able to make this work, you will need an access point connected to a switch to create the wireless network. There are different types of hardware components that are used to set a wireless network up such as network adaptors, Ethernet cables and a hub.

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.

To gain a wireless connection you will need a router/ modem, wireless enabled device and then you need to connect that device to the router.

Within this article, the authors states that in order to provide a safe and secure wireless network, they outlined the counter attacks and measures for the security of wireless networks. Some of the counter attacks that the authors have listed includes, system security - which breakdowns to administrative level security, physical level security, and technical level security, and information security (Ameen et al, 2012). For the purpose of answering the previous question, the main counter attack that would best defend against the problems would be system security - particularly the administrative level security. At this level of security, administrative control over the system by establishing a well defined user hierarchy plus a strong authentication measures, can prevent security breaches of WLANs from

This report fulfills the specific requirement for documentation as specified in FIT 5083 Assignment 1. In this technical report, we will identify the various steps and techniques used in deployment of wireless network. Initially, what is networking or network infrastructure? Networking mean to connect two or more devices and configure them in such a way that they can communicate with each other. In networking, network infrastructure means to connect the software and hardware part rather than actual connection between two devices. Now days, wireless network connections are highly on demand because it’s easy to access and it does not require any cabling structure.

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.

The pοpularity οf wireless netwοrks in hοme has increased in recent years, and the advanced cοmputer technοlοgy has made the persοnal digital device tο cοmmοnly have the capability tο cοmmunicate thrοugh the wireless netwοrk.
