Abstract
A method, a system, and a computer program product for determining a location of a communication device. Data corresponding to a detected transmission of a data packet between a tag device and one or more communication devices is received on one or more communication channels. At least one of a channel state information and a signal strength associated with the detected transmission for each frequency band in a plurality of frequency bands are determined. Based on the determined channel state information, one or more lengths of signal paths corresponding to the detected transmission of the data packet are determined. A shortest length in across one or more communication devices is selected to determine a location of the tag device.
