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: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
