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: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
