This paper presents a directory-less approach based on broadcasted geo tags for positioning in existing WLAN infrastructures based on tagged WLAN access points or GSM base stations with a central tag directory.
Abstract
Existing positioning approaches do not provide the required positioning accuracy for navigation systems in indoor environments. Novel approaches are based on pseudolites (pseudo satellites) which try to emulate GPS (Global Positioning System) satellites. Thus, conventional GPS receivers could be used, but the infrastructure becomes very expensive. Other approaches are based on tagged WLAN access points or GSM (Global System for Mobile Communication) base stations with a central tag directory. When a user wants to determine its position, he queries the central server for the geo coordinate of its current access point or base station. Finally, the server delivers the corresponding coordinate. In this paper we present a directory-less approach based on broadcasted geo tags for positioning in existing WLAN infrastructures.

Location tracking using fiber optic array cables and related systems and methods

TL;DR: In this paper, the authors describe the use of multiple reference units along the length of the fiber-optic array cable, which can be configured to convert received electrical RF signals from the objects into optical RF signals, which are then used to determine the location of the object.
Patent

Localization services in optical fiber-based distributed communications components and systems, and related methods

TL;DR: In this article, the location of client devices can be provided and/or determined based on knowledge of the locations of the component or components in the optical fiber-based distributed communications system in communication with the client device.
Patent

Systems, methods, and devices for documenting a location of installed equipment

Wireless LAN Positioning based on Received Signal Strength from Mobile device and Access Points

TL;DR: This paper proposes a new WLAN positioning approach by making use of the RSS collected at both the access points and mobile device, which is positioning algorithm independent, which means the user can apply any location estimation algorithm with this new data acquisition approach.

A Uniform Resource Identifier for Geographic Locations ('geo' URI)

TL;DR: This document specifies a Uniform Resource Identifier for geographic locations using the 'geo' scheme name to identify a physical location in a two- or three-dimensional coordinate reference system in a compact, simple, human-readable, and protocol-independent way.

Vehicle location system experiment

TL;DR: In this paper, a vehicle location system concept which utilizes narrow-band-radio trilateration has been developed for use in command and control systems designed to dispatch mobile vehicles, and a comprehensive system experiment was carried out in Schenectady, N.Y., designed to evaluate the system's performance in a severe radio multipath environment, and evaluate the improvement in performanee realized by system design options developed to improve performance degradation of multipath.
