Defining Wireless Coverage Areas 127

5Under the General tab, you can do the following:

„In the Name box, edit the name of the coverage area (1 to 60 characters long, with no tabs).

„In the Technology list, select one of the following:

„802.11a

„802.11b

„802.11g

„802.11a and 802.11b

„802.11a and 802.11g

Select 802.11a and 802.11b if the area requires 802.11a and 802.11b coverage. Select 802.11a and 802.11g if the area requires 802.11a and 802.11g coverage.

„For 802.11g, to prevent the association of 802.11b clients to any radio in this coverage area, select Exclude 802.11b clients. To allow 802.11b clients to associate to radios in the coverage area, clear Exclude 802.11b clients.

„In the Rate [Mb/s] list, select the average desired association rate for typical clients in this coverage area.

6Under the Capacity tab, you can do the following:

„To calculate MAP placement and configuration based on coverage and on capacity for data, enable Use Capacity Calculation for Data.

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

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

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

„To calculate MAP placement and configuration based on coverage and on capacity for voice over IP, enable Use Capacity Calculation for Voice.

„In the Active Call Bandwidth list, specify the amount of bandwidth in kilobits per second (Kbps) that you expect for each call.
