Abstract
Systems, methods and computer program products for accurately determining the location of people or objects are disclosed. The location of people or objects is calculated based on a received signal strength indication (RSSI). The distance between a transmitter and a receiver is calculated in a manner that can reduce or eliminate the effect of multiple paths of a signal between the transmitter and the receiver. Therefore, the location system provides a mechanism for determining the RSSI value accurately regardless of the multiple paths between a transmitter and receiver.
