During a call, a radio access network (RAN) may substantially simultaneous communicate with a wireless communication device (WCD) via multiple wireless coverage areas. The number of wireless coverage areas used for this substantially simultaneous communication may vary based on the call type. Thus, for instance, if the call type is a real-time call type, the RAN may use more wireless coverage areas when communicating with the WCD to improve the quality of the call. But, if the call type is a non-real-time call type, the RAN may use fewer wireless coverage areas when communicating with the WCD so that wireless resources are conserved.
