1. A method comprising:
- determining an altitude of a wireless communication device (WCD);
if the determined altitude of the WCD is determined to be above a threshold altitude, a radio access network (RAN) transmitting only a first set of wireless wide area network coverage area identifiers to the WCD; and
if the determined altitude of the WCD is determined to be below the threshold altitude, the RAN transmitting only a second set of wireless wide area network coverage area identifiers to the WCD;
wherein the second set of wireless wide area network coverage area identifiers and the first set of wireless wide area network coverage area identifiers are mutually exclusive.

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.

10. A computing device comprising:
-
a processor; data storage; and program instructions, stored in the data storage that, upon execution by the processor, cause the computing device to (i) determine an altitude of a wireless communication device (WCD), (ii) if the determined altitude of the WCD is determined to be above a threshold altitude, instruct a radio access network (RAN) to transmit only a first set of wireless wide area network coverage area identifiers to the WCD, and (iii) if the determined altitude of the WCD is determined to be below the threshold altitude, instruct the RAN to transmit only a second set of wireless wide area network coverage area identifiers to the WCD; wherein the second set of wireless wide area network coverage area identifiers and the first set of wireless wide area network coverage area identifiers are mutually exclusive. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method comprising:
-
obtaining a first altitude of a first wireless communication device (WCD) served by a wireless wide area network coverage area; determining that the first altitude is above a threshold altitude;
in response to determining that the first altitude is above the threshold altitude, transmitting only a first set of wireless wide area network coverage area identifiers to the first WCD;obtaining a second altitude of a second WCD served by the wireless wide area network coverage area; determining that the second altitude is below the threshold altitude; and in response to determining that the second altitude is below the threshold altitude, transmitting only a second set of wireless wide area network coverage area identifiers to the second WCD; wherein the second set of wireless wide area network coverage area identifiers and the first set of wireless wide area network coverage area identifiers are mutually exclusive.
