摘要： Systems and methods for distance measurement in wireless networks are disclosed. A method for measuring distance between nodes or devices in a wireless network comprises estimating a distance between network devices based on a first distance measurement method, estimating the distance based on a second distance measurement method, and processing the first and second distance estimates to determine convergence and to generate an enhanced distance measurement. Additional distance estimates may be combined to further improve accuracy. Convergence information may be provided indicating whether two or more distance estimates converge. In some implementations, the first distance estimate may be generated by a transmission time estimation method, the second distance estimate may be generated by a received signal strength distance estimate, the two estimates may be combined by averaging to generate an enhanced distance estimate, and the difference between the estimates may be compared to a threshold to determine whether the estimates have sufficiently converged to within a desired convergence range.
