It seemed more like traditional GPS (comparing the time difference from a number of transmitters).
The accuracy of signal strength triangulation is affected by anything that affects the signal, so you couldn't get 2.5cm accuracy with that.
They said they were talking to chip manufacturers, implying that current hardware won't work with this.

Is this the something like wifi triangulation, which a number of
companies (eg skyhook, google, apple, RIM) already do?
