| 20110021207 | System and Method for Estimating Positioning Error Within a WLAN-Based Positioning System - The invention features a method of estimating an expected error of a position estimate for use in a WLAN positioning system that estimates the position of a WLAN-enabled device. The WLAN-enabled device receives signals transmitted by at least one WLAN access point in range of the WLAN-enabled device, and a position of the WLAN-enabled device is estimated based on the received signals from the at least one WLAN access point in range. A signal strength value is measured for the signals transmitted by the at least one WLAN access point, and a maximum signal strength value is determined. The method also estimates an expected error of the position estimate based on the maximum signal strength value of the signals transmitted by the at least one WLAN access point in range of the WLAN enabled device. The expected error predicts a relative accuracy of the position estimate. | 01-27-2011 |

| 20110235532 | System and Method for Resolving Multiple Location Estimate Conflicts in a WLAN-Positioning System - Methods of and systems for resolving multiple location estimate conflicts in a WLAN-positioning system are provided. Disclosed are methods to quantify the probability that a particular location estimate of a mobile device made by a Wi-Fi based positioning system is correct to within an arbitrary accuracy. Implementations use observed access point cluster size, age information for access point location determination, and/or cumulative distribution functions that characterize the conditional probability that one or more access points detected by the mobile device have relocated within a specified time interval to make the probability determinations. | 09-29-2011 |
| 20110235623 | System and Method for Estimating the Probability of Movement of Access Points in a WLAN-based Positioning System - Methods of and systems for estimating the probability of movement of access points in a WLAN-based positioning system are provided. Disclosed are methods to quantify the probability that a particular location estimate of a mobile device made by a Wi-Fi based positioning system is correct to within an arbitrary accuracy. Implementations use observed access point cluster size, age information for access point location determination, and/or the probability that one or more access points detected by the mobile device have relocated based on historic information about the movement of a collection of access points to make the probability determinations. | 09-29-2011 |
