Abstract
A system and method are provided for authenticating a new device in a wireless network using an authentication device. First, the new device estimates the distance between the new device and the authenticating device as a first distance measurement, and sends the first distance measurement to the authentication device. The authentication device then estimates the distance between the new device and the authenticating device as a second distance measurement. The authentication device then evaluates the first and second distance measurements to determine if they meet authentication criteria and sends authentication data to the new device only if the first and second distance measurements meet the authentication criteria. These criteria can be that they do not differ by more than a set error value or that they both are below a set maximum value.
