  • Essay / Wireless LAN Connections as an Alternative to Networking...

    INTRODUCTIONWireless LAN is an option to network cables that you might use to connect your computers at home or in the office. Several variants exist like HomeRF, various so-called IEEE 802.11 (Institute of Electrical and Electronic Engineers) standards, LAN (Local Area Network) over DECT, Bluetooth, etc. If you need to buy a wireless LAN right now, go for one of the 802.11b (cheap, but less secure) or 802.11g variants (a little more expensive, but faster and more secure). Wireless LAN is sometimes called WiFi, however, WiFi is even certified by WECA. It “guarantees” that the devices comply with standards. Data transfer speeds range from 1 Mbps (Bluetooth) up to 54 Mbps (802.11g and 802.11a). For normal Internet use, 1 Mbps should be enough. To copy larger files between two PCs and/or a server requires a little more (depends on your patience). For multimedia purposes (video streaming), 11 Mbps should be acceptable. Keep in mind, however, that most WiFi solutions only achieve half of their “claimed” speeds. !PROBLEM STATEMENTProblem StatementOverviewAs with wired LAN systems; Actual WLAN throughput depends on product and configuration. Factors affecting throughput include the number of users, broadcast factors such as distance and multipath, the type of WLAN system used, and hibernation and bottlenecks on wireless parties of the LAN. Throughput should be defined as the ratio of the expected delivered data payload to the expected transmission time. This is the percentage of undiverted data packets received without error. Additionally, most voice and video applications prefer very small payload sizes to ensure reliable service delivery with minimum delay. Flow is what the user...... middle of paper ...... status becomes complete. As you can see, there are different results in the Mbps column on both sides. This is because the two sides have a different speed for bits per second. You can also save the result by clicking the Print button for future reference. CONCLUSION The conclusions to be drawn from this speed testing report are: Accuracy is only as good as the ability of the testing application to provide the details that validate the test results. Not all speed testers are common and should not be compared unless the differences in their methodology are taken into account. The results of a speed tester should proclaim the method used to perform the test, otherwise the results are meaningless. The testing method must be coordinated for the application profile for the results to be useful when evaluating performance expectations for that application.
