WHERE2 Special Session at European Wireless 2013

Special Session at the European Wireless 2013:

The purpose of this special session is to gather researchers and industry to share views on needs, possibilities and challenges in next generation global mobile and wireless communication systems. Future radio access networks focus on lower latency and higher throughputs and mobility for the user. The availability of position information plays an increasing role in mobile wireless communications networks already today and will be an integral part of future systems. These systems inherently can offerthe ability forstand‐alone positioning especially in situations where conventionalsatellite based positioning systems fail, such as GPS in steep urban canyons or indoor environments. In this framework, positioning information is an important enabler for both location and context‐aware services, but also for the improvement of the communications system itself. Several techniques have been investigated, and continue to be improved by exploiting positioning information, for the coordination of cell sites and the cooperation between them, including cooperation between femto and macro cells, exploiting location and environment information. Research on strategies for the management and relaying in mobile terminals clusters, exploiting geo‐location information have also been ongoing, targeting to improve reliability, connectivity and security of cooperative cluster operation.

Interactive Demo of Cooperative Positioning

This demo calculates the Cramér-Rao lower bound for 2-dimensional positioning using fixed (base) stations as well as mobile radios using a cooperative radio link between mobile radios that are nearby to position the desired mobile radio.
The benefit of cooperative positioning is especially visible inside buildings where
  1. the density of mobile radios is typically higher compared to outside of the buildings and
  2. the radio link between the base station and the mobile radios causes errors in the position estimation due to multipath effects and shadowing.
