LTE Location Based Services Technology Introduction

Global Navigation Satellite System (GNSS) based solutions are highly accurate in most cases, but there are circumstances where they are not as effective, such as in dense urban environments with reduced satellite visibility or indoor areas with low signal levels. LTE Location Based Services (LBS) are designed to determine where a device is located to assist in its effectiveness. This Rohde & Schwarz white paper describes limitations of GNSS systems, as well as LTE cellular based alternatives within 3GPP Release 9.
