Abstract:
In order to provide wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas aimed to direct coverage at different heights. The RAN may advertise the presence of wireless coverage areas that provide elevated coverage primarily to the WCDs above a threshold altitude. Similarly, the RAN may advertise the presence of wireless coverage areas that provide ground floor coverage primarily to WCDs below the threshold altitude. In this way, when a WCD is handed off to a new wireless coverage area, that wireless coverage area may be suited to provide coverage at the WCD's altitude.
