122CHAPTER 5: PLANNING THE 3COM MOBILITY SYSTEM

Configuring Capacity Calculation for Data

3WXM can perform multiple calculations for MAP placement. One is based on coverage only. Another is based on capacity for data traffic, using the data capacity parameters. 3WXM compares the results of the calculations and selects the calculation that results in more MAPs.

1To calculate MAP placement and configuration based on both coverage and on capacity, enable Use Capacity Calculation for Data. Otherwise, click Next.

By default, 3WXM performs only the coverage calculation. If you enable the Use Capacity Calculation for Data option, 3WXM performs both calculations.

2In the Per Station Throughput list, specify the throughput (combined transmit and receive) in kilobits per second (Kbps) for a station.

The throughput value cannot exceed the value you selected for the baseline association rate.

3Com recommends that per-station throughput values do not exceed

1Mbps for 802.11b technology and 5 Mbps for 802.11a/g technology.

3In the Expected Station Count list, specify the number of clients you expect to be in the coverage area.

4In the Station Oversubscription Ratio list, select the ratio for the average transmit behavior of the stations.

The station oversubscription ratio is the ratio of active clients compared to total clients. For example, the ratio 5:1 indicates that, statistically,

20percent of the clients are active at any given time.

5Click Next. The Capacity Planning for Voice page appears.
