introduction Need For Location Accuracy Better Mobile Applications Disaster/Security, e.g. E-911 Better Direction Geo-Fencing Better Mobile Applications Google map with accurate position display.. 4/9/2019 LAWS: Location Accuracy based on Wireless Signals

Problem Statement Determine Location accuracy based on Wi- Fi and GPS signals. LAWS: Location Accuracy based on Wireless Signals 4/9/2019

Background The GPS location of Wireless access point (AP) GPS information – Latitude , Longitude, Altitude. Its inaccuracy comes from blocking of signals from GPS satellites, e.g. indoor problem. Wifi derived location information The GPS location of Wireless access point (AP) BSSID can be used to identify uniquely the signal of an AP. By correlating the strength of three AP signal we can estimate the location of a wifi receiver. The inaccuracy comes from signal to noise ratio, shielding effect LAWS: Location Accuracy based on Wireless Signals 4/9/2019

METRICs for Evaluation Accuracy Time Performance LAWS: Location Accuracy based on Wireless Signals 4/9/2019

Goal of the PROJeCT Conduct experiments to evaluate location accuracy based on Wi-Fi signals and GPS signals. Our experiments focus on outdoor such UCCS Alpine Soccer Field or Alpine parking garage or central court or older Engineering building because we have better shielding effect on the wall door. Develop an Android Application for collecting Wi-Fi base station information., signal strength, device GPS Signals and reported location. Develop and algorithm to calculate android phone location based in the Wi-Fi signal strength. Based on the availability of the base station data, compare the android phone signal strength with those observed by the base station. LAWS 4/9/2019
