copied!<p>You can't find a definite answer, because the throughput will depend on several interference factors which affect all radio signals. At best you'll get an upper bound:</p> <blockquote> <p>802.11b has a maximum raw data rate of <strong>11 Mbit/s</strong> and uses the same CSMA/CA media access method defined in the original standard. Due to the CSMA/CA protocol overhead, in practice the maximum 802.11b throughput that an application can achieve is about <strong>5.9 Mbit/s using TCP</strong> and <strong>7.1 Mbit/s using UDP</strong>.</p> </blockquote> <p>Note that the reach also varies with antenna size and frequency band. </p> <blockquote> <p>Wi-Fi networks have limited range. A typical wireless router using 802.11b or 802.11g with a stock antenna might have a range of 32 m (120 ft) indoors and 95 m (300 ft) outdoors. The IEEE 802.11n however, can exceed that range by more than two times.[30] Range also varies with frequency band. Wi-Fi in the 2.4 GHz frequency block has slightly better range than Wi-Fi in the 5 GHz frequency block. Outdoor ranges - through use of directional antennas - can be improved with antennas located several kilometres or more from their base. In general, the maximum amount of power that a Wi-Fi device can transmit is limited by local regulations, such as FCC Part 15[31] in USA.</p> </blockquote> <p>For a comprehensive network simulation software, take a look at the <em>ns</em> series, e.g. the latest <a href="http://www.nsnam.org/" rel="nofollow">ns3</a>.</p> <p>Sources: </p> <ul> <li><a href="http://en.wikipedia.org/wiki/IEEE_802.11b-1999" rel="nofollow">http://en.wikipedia.org/wiki/IEEE_802.11b-1999</a></li> <li><a href="http://en.wikipedia.org/wiki/Wi-Fi#Advantages_and_challenges" rel="nofollow">http://en.wikipedia.org/wiki/Wi-Fi#Advantages_and_challenges</a></li> </ul>
