In the maze of wireless networking developments, the one factor often overlooked is the promised throughput capabilities versus the actual bandwidth that is available. Picking up an wireless access point and wireless adaptor, you probably expect that you will be getting a bandwidth availability of 54mb-per-second (mbps). Oops. Don’t get too upset when you find out that the actual bandwidth you get is substantially lower. In this paper you will learn why the bandwidth you expect disappears into thin air | Global Knowledge Expert Reference Series ofWhite Papers Wireless Bandwidth Not Necessarily as Advertised 1-800-COURSES Wireless Bandwidth Not Necessarily as Advertised Ted Rohling Global Knowledge Instructor CISSP Introduction In the maze of wireless networking developments the one factor often overlooked is the promised throughput capabilities versus the actual bandwidth that is available. Picking up an wireless access point and wireless adaptor you probably expect that you will be getting a bandwidth availability of 54mb-per-second mbps . Oops. Don t get too upset when you find out that the actual bandwidth you get is substantially lower. In this paper you will learn why the bandwidth you expect disappears into thin air. It s Radio The foremost reason for loss of performance is that wireless networking is really radio. Radio is subject to all kinds of radio frequency interference RFI issues. If your wireless LAN is operating in an environment with wireless telephones microwaves and other devices that emanate radio signals those emanations will interrupt the communication pathway that you expect. It is very similar to trying to hold a private conversation in a crowded noisy sports arena. You have to try hard to communicate and you probably have to slow down when you speak just to be able to hear one another. If you are fortunate enough to have an access point and adaptor that are in an area with no RFI and no other interference sources you will get reasonably good throughput. However in most business settings today that Copyright 2006 Global Knowledge Network Inc. All rights reserved. 2 is not common. Wireless networking creates its own interference. Open your wireless adaptor on your computer and count the number of other access points that you can see. Depending on a number of different conditions each of these access points can cause a reduction in your network performance level. Sharing the Path Each access point is assigned to
