Bounds on Extrapolation of Field Knowledge for Long-range Prediction of Mobile Signals

Teal, Paul D; Kennedy, Rodney


A bound is derived for the extent to which narrow-band knowledge of a multipath field inside a spatially limited region can be extrapolated beyond that region. The bound is independent of any model which may be applied to the multipath field, relying on the field being a solution to the homogeneous Helmholtz wave equation. The bound has implications for the extent and reliability of long-range channel prediction, particularly when the multipath is diffuse.
