Types of Computer Networks

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

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.

The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very

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.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Wireless networking signals are also susceptible to interference from lights and electronic devices as wireless networks use radio signals for transmission. Then there is the issue of stability, because of the interference caused by different electronic devices, often the wireless connection gets lost or distorted. Although the transmission range of a common 802.11g network is on the order of tens of meters and is quite sufficient for a typical home but it is not sufficient for a large setup. In order to increase the range, additional equipment/access points and repeaters will have to be developed and thus the cost will further go up. The transmission speed of wireless networks is slow as compared to the slowest common wired networks. Faster options like gigabit Ethernet are available via cables and are being deployed in specialized environments where the throughput of a wired network is

As wireless technology has begun to mature, the demand for wireless products has increased as new applications for the technology are realized. One application for wireless technology at the U.S. Naval Academy is to use the wireless capability to enhance classroom instruction. Currently the Electrical Engineering and Physics Departments have wireless access points and wireless laptops/desktops available for classroom instruction. The purpose of this report is to provide the technical research necessary to aid decision makers in determining which wireless technologies the Naval Academy should invest.

Wireless networks serve as the transport mechanism between devices and among devices and the traditional wired networks (enterprise networks and the Internet). Wireless networks are many and diverse but are frequently categorized into three groups based on their coverage range: Wireless Wide Area Networks (WWAN), Wireless Local Area Network (WLANs), Wireless Personal Area Network (WPAN )and etc.

The ZigBee technology, has different subdivisions and names and works on the several layers of the OSI model, each having a different name and a distinguished function. This paper focuses on the first two layer of the OSI which is responsible for point-to-point connectivity. The ZigBee technology has an embedded set of features, which can be applied to a wide variety of consumer, commercial and industrial applications. ZigBee builds upon the IEEE 802.15.4 standard, and provides low cost solutions to short distance communications meant mainly for Personal Area Networks. It is in some ways similar to the Bluetooth Technology. This IEEE standard provides characteristics for Low Rate Wireless Personal Area Networks (LR-WPAN). The

Due to the increase in popularity of mobile devices and tablets by consumers, the decline in the Personal Computer Market (Technology, 2013) is escalating, and consequentially, hardware and software development for the mobile market is on the increase as well as the development of Wi-Fi (Wireless Local Area Network) technology.

Wireless networks refer to those networks that make use of radio waves or microwaves in order to establish communication between the devices.

Mobility has become a very common word and rapidly increasing part in today’s computing area. An increasing growth has appeared in the development of mobile devices such as smartphone, PDA, GPS Navigation and laptops with a variety of mobile computing, networking and security technologies. In addition, with the development of wireless technology like WiMax, Ad Hoc and WIFI, users may be surfing the Internet much easier but not limited by the cables as before[3]. Thus, those mobile devices have been accepted by more people as their first choice of working and entertainment in their daily lives.

Wireless Local Area networks (WLANs) have been employed to add mobility features to office and campus networks since the late 1980s. This article presents a discussion of the current state of WLAN technology and some of the products available.

Information and communication technologies have become advanced and efficient in last few decades. The improvement is radical and it has made the broadband technologies and internet more robust and wide spread. Internet has become an integral part of any communication technology. It carries various type of information and offers different type of network services. The speed of data transmission has also improved. [1]Now days, Internet can be accessed from any smart phone, PDA, laptop, computer and several other smart devices. Wireless internet connection through wireless LANs at public places like airports, stations etc. All these have led to the wireless mesh network. [2]

The data transmission is simple and travels in a single direction. There is no data collision. Extra computes can be added with little effect on the performance. Each node connects to two other nodes, making one on going pathway for signals through every single node. Data goes from node to node, with every node handling all the packet.
