Indoor Localization Using LTE Signals with Synthetic Aperture Navigation

Brief Description

This technology enhances indoor pedestrian localization accuracy using LTE signals by mitigating multipath errors through synthetic aperture navigation.

Full Description

A novel approach to indoor localization that leverages broadband communication signals, specifically LTE carrier phase measurements, to improve accuracy. By synthesizing an antenna array from the motion of a receiver and combining received data, this method suppresses multipath error and enhances navigation precision by determining the direction-of-arrival (DOA) of incoming signals.

Suggested uses

• Emergency response systems for precise indoor localization. 
• Navigation solutions for malls, airports, hospitals, and storage facilities. 
• Enhanced indoor positioning for consumer mobile devices. 
• Infrastructure-less indoor tracking systems for logistics and retail.

Advantages

• Improves indoor localization accuracy by effectively mitigating multipath errors. 
• Utilizes existing LTE signals, eliminating the need for additional infrastructure. 
• Enhances precision through carrier phase measurements and synthetic aperture navigation. 
• Capable of determining accurate DOA for improved navigation observables. 
• Adaptable to various indoor environments without the need for dedicated sensors.
