Advantages and Disadvantages of Normal Lan vs. Wireless Lan

Authentication: 802.11 defines authentication services to control LAN access to a level equal to a wired link because wireless LANs have limited physical security to prevent unauthorized access. Every station, whether part of an independent BSS or an ESS network, have to use the authentication service prior to establishing a connection with another station with which it wishes

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

Thus the speed and reliability can be improve by judging the number of antennas. In the aspect of data rate, Option 1 has the highest transfer rate comparing to routers that has single-band capabilities. This indicates that Option 1 is able to perform better by transferring 600Mb data per second, 150 Mb more than other routers. Option 1 is strongly recommended as it is more affordable in prices with comparably better performance. Furthermore, Option 1 is equipped with various wireless LAN standard that provides faster and reliable wireless signals. It uses either 2.4GHz (single band) or 5GHz (dual band) band of frequencies in which wireless communications operate. Demands of dual band arise when there are intensive work within a LAN network and provides better internal network performance due to less interference (Lynn,

Wired network uses cables to connect devices to the internet, however, wireless network uses radio waves to devices to connect internet.

A: The 802.1 standards provide LAN/MAN management. The 802.1 standards where created by the close of the 1970’s.

11. Today, most wireless local area networks use the _____ standard, which can transmit up to 54 Mbps and has a range of about 300 feet.

Today’s current standard of 802.11 is 802.11ac. When comparing newer routers for home use, you will run across routers labeled AC1200, AC1750, AC3200, and so on. The “AC” refers to the wireless standard, while the number following it refers to the speed. The current range of 802.11ac routers can provide speeds up to 1300Mbps on the 5 GHz band, and up to 450 Mbps on 2.4 GHz band. The base level for 802.11ac is more than twice the speed offered from the previous standard, 802.11n. Most routers available in stores today offer 802.11n or 802.11ac, older standards such the “a,” “b,” and, “g” are out of

4. Use the Internet to research one to two applications of the identified wireless technology. List each application found. Reference the websites you used to locate this information.

It was designed to replace 802.11a, 802.11b and 802.11g. It has the fastest transfer rate of (600Mbps) and the longest signal range compared to its predecessors. It operates in both 2.4GHz and 5GHz range.

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.

6. Supposedly, 802.11b is backwards compatible with 802.11g, yet this lab demonstrates there are significant problems with allowing the two to coexist. What is the primary incompatibility between b and g?

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

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.

“IEEE 802 subdivides the data link layer into sublayers, namely the logical link control (LLC) and media access control (MAC) layers, which provide protocol multiplexing and a multi-access mechanism, respectively. IEEE 802 is comprised of standards with separate working groups that regulate different communication networks, including IEEE 802.1, 802.3, 802.11 and 802.15.” (Technopedia, 2014).

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.
