Collaborative Time of Arrival (CToA) 

 

Abstract

 

Collaborative time of arrival (CToA) is a time-delay based geolocation protocol, designed for taking the user capacity of IEEE802.11/Wi-Fi-based, geolocation systems to the extreme. The protocol is broadcast-based and leverages the IEEE802.11 fine timing measurements (FTM) capabilities, enabled in state-of-the-art Wi-Fi chip-sets to support two concurrent operation modes: the “client-mode” enables “GPS-like” operation indoors, and allows an unlimited number of clients to estimate their position and navigate indoors, without exposing their presence in the network. The “network-mode” is designed for large-scale asset-tracking and big-data analytics applications and enables a network positioning server to pinpoint and track the location of thousands of Wi-Fi-enabled objects, where the capacity is limited mostly by the server's processing capabilities. 

 

The presentation will cover the principles of the protocol and the mathematical background of the position estimation algorithms. In addition, theoretical analysis of the expected positioning accuracy and real-life system performance examples will be provided. A whitepaper describing the protocol is available on IEEE Mentor.
