Net architects need a basic understanding of the impact of WEP on the performance of high-demand Wlan applications, such as file transfers. This report identifies performance issues when running Wired Equivalent Privacy (WEP) on 802.11b LANs. 802.11b access points and NICs from these companies: Cisco Systems, Inc Orinoco 3Com Corp. and D-Link Systems, Inc were tested.

While wireless LANs that support the Ieee 802.11b standard are able to deliver a maximum throughput on a LAN segment of about 6 Mbit/s, that throughput expectation does not account for the possible impact that security, such as the Wired Equivalent Privacy (WEP) technology, has once it is enabled on the network. In this report The Tolly Group examines what impact, if any, that WEP has on 802.11b throughput and what security-related factors come into play to influence achieved throughput rates.

Everyone knows that security (as in encryption) is a must for wireless LANs. With shareware programs like NetStumbler, anyone armed with a laptop can link up to your access point (AP) and “join” your network and/or sniff the wireless portion of it.

While WEP is known to have flaws (it can be cracked), READ MORE >
