A unit of measuring position with standing-wave radio-positioning systems. In phase-comparison (CW) systems, a lane is one cycle of the standing-wave interference pattern resulting from two radiated waves and it depends on the position within the network. Phase-comparison systems yield location within a lane but do not necessarily determine in which lane; lane ambiguity has to be resolved by counting lanes or by some additional measurement. Lane shape (circular, hyperbolic, elliptical, or a combination) depends on the system configuration. See Figure L-6.
