a communications system that is already planning to replace

Deutsche Bahn has stopped all its trains on Tuesday night after the GSM-R network fell. This network is basically the digital system that allows machinists and control centers to speak. The service was finally restored around 12:50 a.m., according to media reports such as the BBC, after more than two and a half hours of total paralysis. What happened. At 10:30 p.m. on Tuesday (local time), Deutsche Bahn announced that all its trains were being held at stations for a widespread failure in the GSM-R networkthe digital radio communications system that connects drivers with railway traffic management centers. Without that connection, basically no train can run safely. So the operator chose to paralyze its entire railway network, both long-distance and regional trains and also the S-Bahn (which are commuter trains that link the suburbs with urban centers). What is GSM-R and why is it so critical. The acronym corresponds to Global System for Mobile Communications–Railway, an adaptation of the 2G standard designed specifically for railways. According to the European Union Railway Agency, It has been implemented throughout Europe since 2000 as a common operating system. The objective of the system is to guarantee communication between train drivers and signal control stations. It is mandatory and essential, so without that active line, it is impossible to operate safely. Deutsche Bahn already knows that the system is obsolete, in fact has signed a contract with Nokia to replace it with a 5G network based on the FRMCS (Future Railway Mobile Communication System) standard, but in the meantime it continues to depend on it. As has managed the problem. Shortly after midnight, the company announced that had identified the cause of the failurealthough without specifying which one it was. Technicians worked to restore the network, which was back up and running around 12:50 a.m. Deutsche Bahn CEO Evelyn Palla counted to the newspaper Bild that they managed to “stabilize the situation with an emergency system.” The company distributed taxi and accommodation vouchers for affected passengers and offered alternative transportation where possible. He also set up stationary cars at the stations so that travelers could wait seated. No signs of cyber attack. The Register points out that there are no indications that the incident was the result of a computer attack, nor of cable cuts or other physical failures that could explain a drop in national coverage. What the same media does point out is that a network that supports such critical infrastructure should have sufficient layers of redundancy to avoid this type of total paralysis. The exact cause of the failure has not yet been made public. Infrastructure under renovation. It seems that delays and interruptions have become increasingly frequent on the German rail network, a country that has historically boasted punctuality in its trains. Deutsche Bahn, the public operator, has been carrying out renovations on its main lines for years to try to counteract the deterioration of its infrastructure, a deterioration that has been accumulating for decades by insufficient investment. However, a complete technical shutdown of the entire network is quite unusual. And when Germany has paralyzed its trains in the past, it has usually been due to meteorological causes, not due to technical failures.

At the age of 16 he created a picosatellite from his room in Madrid. Today your company is at the global forefront in IoT communications

While the majority of 16-year-olds were thinking and doing other things, it occurred to Julián Fernández (La Línea de la Concepción, Cádiz, 22 years old) create a 250 gram picosatellite from scratch. That project and that ambition changed his life and ended up causing him to found Fossa Systems in 2018. Today, six years later, we are faced with a leading company in this market that has things very clear and a spectacular projection. From Gran Vía to space. Fernández commented in a recent interview on RTVE how Fossa is the Spanish company that has launched the most satellites into space: currently there are 24 satellites. The project of his company – based on Madrid’s Gran Vía street – is to create a constellation of 80 small satellites. They have that many licensed, and all of them are specifically designed for communications with IoT devices. This is not a Starlink. Comparisons are odious, but often useful, and it is inevitable to look at Starlink, SpaceX’s satellite network. The latest versions of its satellites weigh between 800 and 1,250 kg, while Fossa’s nanosatellites do not exceed 6 kg. Starlink’s need huge solar panels because processing their broadband communications consumes a lot of energy, while Fossa’s use batteries that can last up to ten years. Nanosatellites for IoT. The focus is also very different, because Fossa’s nanosatellites have the mission of moving small packets of data in an ultra-efficient way. They are designed so that a sensor on an oil barrel, cow collar, or cargo container sends short, informative messages such as “pressure level OK” or “location: X.” They are totally designed for those short and critical communications in the Internet of Things. Spain is beginning to truly emerge. Fossa has already raised more than 12 million euros between private and public financing, has more than 50 employees and headquarters in Madrid and Portugal—and soon in Asia. They have become an absolute benchmark in their segment. and although at the moment they are launching with SpaceX, they hope to do so soon with PLD Spacethe other jewel in the Spanish aerospace crown: “Spanish satellites on Spanish rockets.” Satellite sovereignty. Fossa’s technology is being especially used in the defense sector: more than 80% of its turnover comes from this segment. As Fernández explained in that interview, “we cannot depend on the US for a technology as critical as satellite communication and sovereign and independent systems are needed.” A notable bet. The fact that Spain is, for the first time, the fourth European country that invests the most in space. Along with Poland it is the one that has increased its contribution the mostwhich now reaches 22,000 million euros. Hello, “New Space” model. Fossa has taken advantage of a new paradigm known as “New Space” in which from large space megaprojects we move to agile developments in which miniaturization and cost reduction is enormous. Fossa Systems is capable of creating a new satellite and putting it in space in six months, but that satellite also costs hundreds of thousands of euros, not tens of millions of dollars. There is another fundamental advantage: Fossa Systems does everything except the design and manufacturing of the semiconductors and the launch of the satellites. That verticalization, that “not depending on almost anyone” is another of its strengths. The future: satellites (somewhat larger)… and licensing. From that initial picosatellite of 250 g we have moved on to the current FOSSASat FEROX of about 6 kg, but the future involves manufacturing somewhat larger satellites of about 20 kg. They hope to complete their constellation of 80 satellites before 2030, and while they do so, Fernández has another objective that he will surely have no problem completing: obtaining his degree in telecommunications engineering at the Rey Juan Carlos University in Madrid, where he is currently pursuing that degree.

Your future is no longer in communications

Telefónica is about to complete a historical transformation that completely changes the nature of your business, as published by Expansion After the first public intervention of his new CEO, Emilio Gayo, in the great Catalunya Expansion meeting. The current situation. 43% of Telefónica’s business income in its four main markets (Spain, Germany, the United Kingdom and Brazil) already comes from services that are not communications. Why is it important. This silent transformation shows how the one that was a simple telephone operator is leaving its traditional business behind to become a diversified technological company. Telefónica is close to that turning point where more than half of its business billing will come from technological services, not voice or data. Right where I wanted to be. In detail. The IT technology segment is growing “in double digit” according to Gayo, while the traditional telecommunications business has already exceeded its peak of investment in infrastructure such as fiber and 5g. The investment ratio on income (capex) will go from 12.9% in 2024 to no more than 12.5% ​​in 2025. This reduction does not mean less investment, but greater efficiency and adjustment to real needs. The general panoramic. Telefónica seeks to redefine itself as a “tractor company” at European level, betting on two parallel strategies: Consolidation in key markets (Spain, Germany and the United Kingdom) where “will study any option that is raised.” Accelerated growth in non -traditional technological businesses grouped in Telefónica Tech. The contrast. While in Europe the operator is committed to growing and consolidating, in Latin America (Chile, Ecuador, Mexico, Uruguay and Venezuela) will continue releasing ballast ballast that does not stop causing losses and erode their margins. Only Brazil is a big business for Telefónica in the American continent. The transformation began in 2019 and the results are already visible. In Spain he has closed 2024 “with figures that we did not see since 2018” (precisely a merit of Gayo before his new promotion), growing in all parameters. In the United Kingdom, he has generated “the expected synergies 18 months before the committed.” And now what. The question is whether Telefónica will complete this metamorphosis without losing positioning in your traditional business. Gayo has pointed out that Movistar Plus remains “a key lever” for the residential segment, letting read between lines that will not completely abandon its roots while reinvesting. The success of this strategy could mark the way to other European operators trapped between American technological giants and Asian manufacturers.
