Hybrid approach to underpin 3G location services

16.03.2004


Imagine your mobile phone telling you of hotels, restaurants and other services in your immediate vicinity no matter whether you’re in an underground shopping mall or on a remote hilltop in the Alpujarras. Such abilities are the aims of EMILY.



Positioning based on both GSM and satellite

The problem in the past has been that cellular positioning systems can be highly accurate in urban locations and indoors where special GSM antennae have been installed. However they lose accuracy in remote rural areas. By contrast, satellite-based positioning services like GPS function well in open areas, but are not so reliable when handsets are indoors or underground.


Scheduled for completion at the end of December 2004, participants in IST project EMILY aim to develop a hybrid device location service able to exploit the abilities of both GSM networks and satellite-based positioning. The objective is to provide a service prototype for handset positioning that will work under all conditions.

Project participants have taken a novel approach to counter this problem. According to project coordinator Monica Schettino of Ertico, "By combining the two different technologies, we solve the positioning problems in rural areas where GSM positioning is weak, and also in indoor areas where GPS has problems. Using a hybrid of the two systems improves the availability and accuracy of both positioning technologies."

3G networks already here

The EMILY approach is intended to provide a basis for the location-based services expected to be in demand for the coming third generation of mobile phones (3G). 3G networks are already a reality in many parts of the world. Japan launched the world’s first commercial 3G network in 2001, and similar networks are now operating commercially in Austria, Italy, Sweden and the UK, with more launches anticipated during 2003-2004.

Testing of the prototype solution is expected to begin in May 2004. Project partner Bouygues Telecom plans to test integration and validation of the system in the Bouygues region of southern France.

There is little if any size penalty for the handsets, says Schettino. "The handset prototype is a typical size, developed for commercial markets." Potential applications include location-sensitive information and billing, roadside assistance services, proximity detection, navigation services and vehicle/goods tracking. "We have had positive feedback already from navigation-mapping providers for example, and from location-based service providers for cellular operators. There are many people interested in these services."

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
