  • LTE Location Based Services Technology Introduction White Paper
    LTE Location Based Services Technology Introduction White paper LTE Location Based Services (LBS) involve the process of determining where a device is located. Global Navigation Satellite System (GNSS) based solutions are highly accurate and the technology of choice for absolute position accuracy, providing the device has a good line-of-sight, but this is not always the case. A device can be in a highly dense urban environment with reduced satellite visibility or indoors with very low signal levels. These limitations of GNSS systems have meant that LTE cellular based alternatives have been developed within 3GPP Release 9 and onwards. They are described in this white paper. .02/ CI 01.00 3573.7380 Template: 1SP05 J. Schütz J.

  • HERE, Mediatek Team up to Deliver Advanced Global Positioning
    Press release HERE , MediaTek team up to deliver advanced global positioning solutions 11 for IoT tracking devices MediaTek selects HERE Network Positioning to support fast and accurate location fix 20 April 2017 AMSTERDAM, Netherlands and HSINCHU, Taiwan – In a world with billions of connected sensors, advanced location positioning technology is unlocking new opportunities for businesses everywhere. HERE Technologies, a global provider of location services to the Internet of Things (IoT) industry, and MediaTek, one of the world’s largest fabless semiconductor companies, today announced a collaboration to enable the HERE Network Positioning solution on select MediaTek chipsets. “We are pleased to work with HERE to connect the next billion to the devices and technologies they want,” said YuChuan Yang, Deputy General Manager of Internet of Things Business Unit, MediaTek. “Network positioning is a crucial component of the connected experience and HERE’s database improves positioning accuracy significantly. We look forward to continuing to blend our strengths with those of HERE for the benefit of our customers around the world.” HERE Network Positioning employs proprietary technology to determine a device’s location rapidly and accurately based on mobile network and Wi-Fi signals. As part of this collaboration, MediaTek offers to device manufacturers a 4-in-1 combo solution based on the MediaTek MT2503 product family, a highly integrated ARM-based SiP design that contains Bluetooth, multiple GNSS receivers and an integrated 2G modem. In one of the first implementations, 3G Electronics, a China-based IoT customer of MediaTek, recently introduced a children’s smartwatch series called KidsWatch, which is powered by MediaTek chipsets featuring HERE’s Network Positioning solution in products sold outside China.

Publication 735 Jakub Marek Borkowski On Applicable Cellular Positioning for UMTS Thesis for the degree of Doctor of Technology to be presented with due permission for public examination and criticism in Tietotalo Building, Auditorium TB109, at Tampere University of Technology, on the 23rd of May 2008, at 12 noon. Tampereen teknillinen yliopisto - Tampere University of Technology Tampere 2008 ISBN 978-952-15-1971-0 (printed) ISBN 978-952-15-2016-7 (PDF) ISSN 1459-2045 On Applicable Cellular Positioning for UMTS Jakub Marek Borkowski April 29, 2008 Abstract Enabling the positioning of cellular handsets increases the safety level and at the same time opens exciting commercial opportunities for operators through providing location-based services. A major implementation obstacle, which prevents a wide deployment of cellular location techniques is the requirement of modifications of the existing network infrastructures and a need for the replacement of legacy terminals. Despite a significant amount of research on the mobile positioning problem, there are still unresolved aspects regarding applicable positioning solutions providing es- timation accuracy sufficient for the majority of location-based services. Typically, the applicability of positioning technology in current networks and provided estimation accuracy yield for trade off. The aim of the research performed in the frame of this thesis is to propose network- and mobile-based location techniques for UMTS networks that do not require any changes on the network side or in the user terminals and at the same time provide a reasonable estimation performance.

  • Location Data in Body Worn Systems March 2021 Table of Contents
    WHITE PAPER Location data in body worn systems March 2021 Table of Contents 1 Summary 3 2 Introduction 4 3 Location data usage 4 4 Obtaining the data 4 4.1 Techniques for positioning assistance 5 5 Positioning with Axis body worn cameras 5 5.1 Positioning assistance 5 5.2 Important considerations 5 2 1 Summary Body worn cameras can store various types of metadata in the recordings. Location data is one example. By tying the video to the geographical coordinates where it was filmed, the evidentiary value of the recording can be significantly enhanced. Body worn cameras from Axis obtain location data through communication with several navigational satellites. When starting up the body worn system, it typically takes up to 15 minutes in clear conditions (or longer, depending on weather and environment) to establish satellite communication and pick up enough data. The waiting time is kept down by use of positioning assistance which pre-downloads satellite data from servers while the cameras are docked. Unlike many other types of GPS devices, such as smartphones and navigators, Axis body worn cameras cannot use nearby cell towers or Wi-Fi networks to determine their location. Satellite coverage is needed, which means that the cameras can store coordinates only when used outdoors. 3 2 Introduction With a body worn camera, incidents can be recorded wherever they occur. Mounted on the body of an official, the camera is brought to where it is needed and can capture events that would never have been caught by fixed cameras mounted in predetermined locations. A recording produced by a body worn camera comprises a piece of trusted and secure evidence, objectively showing what happened at the scene of an incident.
