Position identification in wireless network using radio signal strengths
A recently granted patent (Publication Number: US11852741B2) discloses a method for identifying the position of a user equipment within a wireless communication network. The method involves identifying a sector portion as an initial search space based on timing advance values, providing expected radio signal strengths, defining initial attenuation based on predetermined values for obstacles, obtaining measured signal strength, determining an estimated area element, and computing a final attenuation. The process iterates at least twice, with each iteration refining the initial attenuation based on previously computed final attenuations.
Furthermore, the patent includes additional claims related to refining the initial attenuation in subsequent iterations, determining the estimated area element based on probability distributions, defining an uncertainty area around the estimated element, computing average expected signal strengths, and implementing the method in a wireless communication network. The method aims to accurately pinpoint the user equipment's position within the network by iteratively refining the attenuation values and considering probability distributions of the equipment's location within the search space. The patent also covers the application of this method in various types of wireless communication networks, including mobile telephony and Global Navigation Satellite System networks.
