A new remote control system for base stations increases the range of mobile phones

07.05.2003


The explosive growth in mobile phones has been supported by a similar growth in the underlying networks of base stations used to connect calls. This has created headaches for network administrators charged with keeping an increasing numbers of base stations active at all times. Now a convenient new power and management cabinet allows administrators to manage the entire operation of base stations remotely, reducing time and costs and improving range.



EUREKA project SAEB98 brought together a Spanish lead partner, Amper Soluciones, with expertise in telecoms network management systems and a German specialist in power plants for the industry, Ascom Energy Systems.

”Base stations for mobile phone networks are normally located in places where access is quite difficult," explains Galilea. "With our system, the operator can remotely determine the real problem in the base station and monitor other systems such as alarms and communication lines as well as air conditioning, an external beacon, and even whether the door is open.”


Some problems can be solved remotely while others are detected in advance so that maintenance staff is forewarned about the problem.

The control unit is built in a small cabinet and offers at least 25 per cent more power in the same volume than existing models. The extra power increases the range of the base station and the small size means the station can be installed in awkward locations such as petrol stations or church spires.
A battery subsystem maintains supply in the event of a power cut.

The remote management strengths of the unit show through in daily maintenance of the station, says Juan Carlos Galilea Technical & Technological Support Director of Amper Soluciones.

Administrators can monitor the state of the base stations continually and fix any problems remotely as they arise.

Galilea stresses the importance of using software simulations to speed up the design process. Rather than build prototypes, for example, the project partners used computer simulations to adjust the density of elements in the power system and keep the temperature under control.

“Simulations and then mechanical prototypes were used to determine the final structure. This allowed us to reduce development costs,” he says.

"The best thing about EUREKA is the ease with which companies from several countries of the European community can work on a common project,” says Galilea, “they can utilise each other’s expertise without having to deal with bureaucracy".

The partners now aim to supply the cabinet to network operators in Europe and around the world.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
