US Patent 10935627 Identifying potentially manipulated radio signals and/or radio signal parameters

A method performed by a mobile device is disclosed that includes obtaining one or more first radio signal parameters of one or more radio signals at a first position of the mobile device and obtaining sensor information indicating a movement of the mobile device from the first position to a second position. The method also includes obtaining one or more second radio signal parameters of the one or more radio signals at the second position of the mobile device and determining, at least partially based on the first radio signal parameters and the sensor information, whether the second radio signal parameters are expected or unexpected for the second position of the mobile device. A corresponding apparatus and computer-readable storage medium are also disclosed.
