Abstract
The system and method uses a one or more pilot beacons to more accurately locate the position of an indoor mobile device. Modulation and level control of the co-pilot beacons provides a third dimension, z-axis, of positioning. An augmented Position Determining Entity ('aPDE') can be used which does not modify the existing PDE in the network, and facilitates and ensures high-integrity information during a 2D to 3D positioning upgrade.
