Wireless technology has become the wave of the future. From cellular phones to wireless point of sale devices, wireless networks and technology is all around us. In order to jump on the wireless train, one must first understand the different standards. To properly and safely utilize wireless technology the user also must understand the various types of wireless security. Once grasping these technologies and standards, anyone can implement a wireless network in their home. First, the 802.11b wireless networking standard, which is the most common consumer based standard. The 802.11b standard's frequency is in the 2.4 GHz range which is common with most cordless land line telephones and some microwave ovens. There are not really many …show more content…
An upgrade to 802.11b is 802.11g which offers some of the same technology as 802.11b but with significant upgrades and improvements. The most significant improvement over the 802.11b standard is the speed. 802.11g supports speeds upwards of 55mbps which is a huge increase over the 11mbps of 802.11b. This standard operates at 2.4 GHz which is the same frequency that the 802.11b standard operates at. Another great thing about the 802.11g technology is it is backwards compatible with a 802.11b wireless card so there is no need to go out and buy a new wireless network card for your computers. Finally a brand new standard that is still in its infancy stages and still has yet to be ratified by the IEEE is 802.11n. 802.11n will be a huge step towards equality amongst wireless and wired networks. First, the standard sets a speed requirement of at least 100mbps which is common amongst most wired computer networks. It is most likely that the throughput will be in the 200mbps range with a maximum being set in the 600mbps range. Looks like the 802.11n standard will be operating at both 2.4 GHz and 5 GHz frequencies. Look for the final 802.11n draft out in April of 2009. After choosing a particular standard to go with and buying the equipment to support that standard, one need to know the method of security they wish to implement on their
Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.
The network level security will form the relationships of authentication, encryption and authorization for the wireless network and its connectivity between wireless clients to the internal network. Some recommendations are:
To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from
Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do
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
3. Specify the standard transmission distance and transfer speed for the wireless technology you identified.
What would happen if wireless devices were not governed by the Wi-Fi Alliance and each vendor had its own standards and protocols? What impact would this have on your personal life or business communications?
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.
Party Plates Company has established the need for a new proposal with wireless technology. Team B will research some marketing tools that will assist Party Plates in meeting their goals of advancement in sales and certain goals. This proposal will focus on wireless technology that will be beneficial to the party plate business. Team B will also provide the pros and cons to these wireless technologies and justification of the choice to incorporate them into Party Plates Company. In the proposal, Team B will also include a spreadsheet presenting the equipment needed for using the technologies and the costs
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.
5G is the fifth generation wireless broadband technology based on the IEEE 802.11ac standard. 5G is provide high speed then 3G and 4G. 5G operates on 5GHZ signal and set is to offer speed up to 1 GB/s.

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.
