摘要： Systems and methods for tracking a wireless device are disclosed. According to one aspect, the wireless device includes a hybrid global positioning system (GPS) and wireless local area network (WLAN) circuit board for seamless indoor and outdoor tracking. In embodiments, GPS and WLAN data are combined to obtain a position estimate of the device. In other embodiments, the circuit board automatically switches between WLAN and GPS data for indoor and outdoor environments. A Location Based Services (LBS) algorithm for determining the position of a wireless device using WLAN and/or GPS signals is also disclosed. The LBS algorithm is implemented by way of method steps including: sensing GPS and/or WLAN signals, measuring and/or converting the sensed signals to obtain distance data, fusing the distance data, and applying one or more approximation algorithms to the distance data to obtain a position estimate of the wireless device. A method for rendering position data using a Marching Cubes algorithm is further disclosed.

摘要： Systems and methods for distance and location tracking a wireless device are disclosed. More specifically, according to one aspect of the present disclosure, a Wireless Area Network-Location Based Services (WAN-LBS) algorithm that utilizes a hybrid Wireless Area Network (WAN) and Global Positioning System (GPS) circuit board and method for seamless indoor and outdoor tracking is disclosed. The WAN-LBS algorithm, in conjunction with the hybrid WAN/GPS circuit board, optimizes the degrees of precision and accuracy for distance measurements in locating a fixed or mobile IEEE 802® device. In one embodiment, the hybrid WAN/GPS circuit board according to the present disclosure integrates the data of a GPS receiver and several IEEE 802 standards based receivers. In another embodiment, the WAN-LBS algorithm according to the present disclosure utilizes received data, acquired by the hybrid circuit board, to calculate distances to the tracking devices, seamlessly in both indoor and outdoor environments.
