Doubling the Accuracy of Indoor Positioning: Frequency Diversity

Doubling the Accuracy of Indoor Positioning: Frequency Diversity

Determination of indoor position based on fine time measurement (FTM) of the round trip time (RTT) of a signal between an initiator (smartphone) and a responder (Wi-Fi access point) enables a number of applications. However, the accuracy currently attainable—standard deviations of 1&#8...
