Defining Wireless Coverage Areas 135 In the Active Handsets per AP list, specify the number of voice over IPphones that you want each MAP to handle. In the Expected Handset Count list, specify the number of voice overIP phones you expect to be in the coverage area. In the Handset Oversubscription Ratio list, select the ratio for theaverage transmit behavior of the voice over IP phones.The handset oversubscription ratio is the ratio of active handsetscompared to total handsets. For example, the ratio 4:1 indicates that,statistically, 25 percent of the voice over IP phones are active at anygiven time.7 Under the Associations tab, you can do the following: In the Mobility Domain list, select the Mobility Domain that containsthe MAPs used for this coverage area. In the Radio Profile list, select the radio profile to be used for thiscoverage area.All radio profile policies configured in the network plan are listed. Inaddition, a default policy is listed. If you select default, the defaultradio profile settings are applied to the coverage area. (Forinformation about policies, see “Configuring and Applying Policies”on page 387.) In the Shared Area list, select a coverage area that will share MAPaccess points with the one you are configuring. If you selected two radio technologies when defining the coveragearea, a shared area is automatically created. In the Wiring Closet list, select the wiring closet that contains the WXswitch or switches to be connected to the shared MAPs. In the Redundant Wiring Closet list, select the wiring closet that willprovide redundant connection to the MAPs. This is required fordirectly connected MAPs, if you require the MAPs to have redundantconnections. Otherwise, this is not required. In the Available Access Points box, select an available MAP, if one isconfigured, to use in the coverage area, then click Add to move theMAP to the Current Access Points box.This assumes that the network plan already has a MAP and that theMAP is physically located within the area you are configuring. If youare planning a new installation, you do not need to specify a MAP touse.
