Abstract
A method in a mobile wireless communications handset located in a multi-level environment, for example a multi-floor building, including receiving first altitude information, for example the floor number, from an altitude information transmitter when the handset is on a first level, and receiving second altitude information from an altitude information transmitter when the handset is on a second level different than the first level. The different altitude information may be transmitted from different transmitters on corresponding levels, or from a single transmitter, located for example in an elevator.
