High Accuracy VLC Indoor Positioning System With Differential Detection

A 3D ultrasonic positioning system with high accuracy for indoor application

In the last years, a few Ultrasonic (US) positioning systems were presented which are primarily directed at indoor tracking of mobile devices. The US positioning system LOSNUS presented in this paper widens the application additionally supporting locating of static devices which can be numerously deployed communicating via a wired or wireless sensor network. However optimized for cheap realizat...

VLC-Based Positioning System for an Indoor Environment Using an Image Sensor and an Accelerometer Sensor

Recently, it is believed that lighting and communication technologies are being replaced by high power LEDs, which are core parts of the visible light communication (VLC) system. In this paper, by taking advantages of VLC, we propose a novel design for an indoor positioning system using LEDs, an image sensor (IS) and an accelerometer sensor (AS) from mobile devices. The proposed algorithm, whic...

LAT Indoor MIMO-VLC

Visible Light Communications (VLC) is an innovative technology that uses the visible spectrum for high-speed data communications. In this paper we investigate the use of MIMO in the design of luminaires supporting VLC and, specifically, in enabling localization and high data rate services. Localization and transmission appear as two different problems in the communication system; however, the f...

Lumicast TM : A high accuracy indoor positioning system based on visible light communication

Nextechs Indoor Positioning System

The Nextechs Indoor Positioning System (NIPS) is an UWB based system for high resolution, high accuracy, 3D location of objects indoor. The system consists of an infrastructure of fixed, active objects called NODES that perform ranging measurements with the objects that are to be located, called TARGETS. Signal time of flight (tof) from nodes to targets is measured in order to compute distances...
