Questions about Wireless Distance Estimation Method for Indoor Positioning Systems

Question 1

How does the method ensure baseband coherence between the RF signals at each device?

The method maintains baseband coherence by synchronizing the baseband signals carried by the RF signals transmitted and received by each device.

Question 2

What are the potential limitations of using dual tone RF signals for estimating distances between wireless devices?

The potential limitations could include interference from other RF signals, limited range of the dual tone signals, and accuracy issues in environments with high levels of noise.

Original Abstract Submitted

A one way ranging method estimates a distance between first and second wireless devices using a technique that involves exchanging dual tone RF signals between the devices and, at each of the first and second devices, maintaining “baseband coherence” between baseband signals carried by the RF signals transmitted and received by each respective device.
