Abstract

See full text

The present invention provides a solution to mistaken location calculations based on multipath effects. The present invention determines a real-time location of an object in a facility using a combination of location algorithms, with a signal characteristic for a wireless signal from a communication device attached to the object received at a sensor of a mesh network. The location algorithms preferably include at least two of a proximity algorithm, a radial basis function algorithm, a maximum likelihood algorithm, a genetic algorithm, a minimum mean squared error algorithm, a radiofrequency fingerprinting algorithm, a multilateration algorithm, a time difference of arrival algorithm, a signal strength algorithm, a time of arrival algorithm, an angle of arrival algorithm, a spatial diversity algorithm, and a nearest neighbor algorithm.
