Model the Access Points

You will now determine how many access points are required to cover your building with a

specified data transfer rate and overlap.

In this example we will use the Coverage Model and make the following assumptions about the

performance of our WLAN.

z Radio Types: a/b/g

z Overlap factor: Medium (150%)

z 802.11a desired rate: 48 Mbps

z 802.11b desired rate: 48 Mbps

Select “801.11 a|b|g” from the Radio Type pull-down box.

Select “Medium” from the Overlap Factor pull-down box.

Notice that the percentage show at the left of the pull-down box changes to 150%.

Select “48” from the 802.11 b|g Desired Rate pull-down box.

Select “48” from the 801.11 a Desired Rate pull-down box.

Notice that the number of required APs has changed to 5.

Click Save, then Apply.

Model the Air Monitors

You will now determine how many air monitors are required to provide a specified monitoring

rate.

In this example we will continue to use the Coverage Model and make the following assump-

tions:

z 802.11 b|g monitor rate: 48 Mbps

z 802.11 a monitor rate: 48 Mbps

Select “24” from the 802.11 b|g Monitor Rate pull-down box.

Select “24” from the 802.11 a Monitor Rate pull-down box.

Notice that the number of required AMs is now 2.

Click Save, then Apply.
