Abstract:	We propose a new positioning technology, Phantom Positioning, to enhance the accuracy of RF propagation models by replacing each transmitter with a phantom (virtual) transmitter at a different location. By taking the position of a phantom transmitter, instead of the original transmitter, as the input to the signal propagation model, the Phantom Positioning technology may obtain a more accurate distance estimation than that of taking the position of the original transmitter as the input. A more accurate distance estimation will lead to a more accurate position determination. Our initial experimental results indicate an up to 20% and 12% improvement on the accuracy in estimating distance and position, respectively. Our technique can be applied to various positioning models to enhance their accuracy or to reduce their training samples.
