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: (Re)solving the jet/cocoon riddle of a gravitational wave event

An international research team including astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has combined radio telescopes from five continents to prove the existence of a narrow stream of material, a so-called jet, emerging from the only gravitational wave event involving two neutron stars observed so far. With its high sensitivity and excellent performance, the 100-m radio telescope in Effelsberg played an important role in the observations.

In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors....

Im Focus: Light from a roll – hybrid OLED creates innovative and functional luminous surfaces

Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.

The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...

Im Focus: Regensburg physicists watch electron transfer in a single molecule

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
