Millions to protect a war frigate. A Bluetooth tracker worth a few euros has been enough to follow her in real time

by

Protecting a warship costs a fortune. We are talking about sensors, protocols, personnel, weapons and a security chain designed to minimize any unnecessary exposure. That is why what has happened with the Zr.Ms. Evertsena frigate of the Netherlands Navy integrated into the battle group of the French aircraft carrier Charles de Gaulle. According to Omroep Gelderlandtheir position could be tracked in real time for hours with something much more mundane and cheaper: a simple Bluetooth tracker sent via military mail. The story does not begin with a technological gap or with a particularly complex maneuver, but with something much more earthly: a postcard. That was what the aforementioned medium used to introduce the tracker into Evertsen through the military mail service. The sources do not specify what device was used, beyond describing it as a low-cost tracker. It is easy to think of a Apple AirTagbut there is no indication that it was that specific model and the market offers many similar alternatives. How a minor failure left a frigate exposed The case gains another dimension when you look at what Evertsen’s mission was at that time. According to the source, the frigate was part of the group that escorted the Charles de Gaulle and its function was to help protect the aircraft carrier of possible air or missile threats. This task makes its location especially sensitive data within an ongoing military mission. In other words, it was not just about knowing where a ship was, but about being able to keep track of a relevant piece within a real operation. The really delicate thing about this episode is not only that a tracker managed to enter the military postal circuit, but what that suggests about certain procedures that continue to operate with a logic from other times. According to the media itself based on official videos from the ministry, the packages did go through X-rays, but the envelopes did not follow the same control. That combination opened enough of a gap to compromise the discretion of the deployment. We are not facing a spectacular failure, but rather an apparently minor vulnerability, but sufficient to allow the ship to be monitored. Once the initial filter was passed, the case stopped being a hypothesis and became a real follow-up. According to the reconstruction published by the Dutch media, the tracker signal made it possible to follow a path that went from Netherlands to Cretewith steps through Den Helder and Eindhoven airport before reaching the port of Heraklion. There, in addition, images from a camera fit that clue and showed the Evertsen moored at the dock. On March 27, once out of port, the frigate continued broadcasting its position for about 24 more hours: first it skirted the Cretan coast and then headed east, until the device stopped giving a signal near Cyprus. The official reaction came after publication and was, at least in part, corrective. The Dutch Ministry of Defense made changes following this incident and stopped allowing battery-powered greeting cards to be sent to Evertsen, as well as announcing a broader review of military mail guidelines. At the same time, the department held that the tracker was located while the correspondence on board was being sorted, once the frigate had already left the port. And although he admitted that the ship could be followed at sea, he assured that this did not constitute an operational risk. There is a quite obvious reading in closing this story. The frigate was still part of a military mission, protected within a much larger device, and yet a low-cost domestic object managed to open a tracking window for hours. Not because it replaced the big threats, but because it slipped through a minor seam that no one had fully adjusted. That’s what makes this episode especially revealing: remember that, in 2026, security doesn’t just depend on large systems.

Sony WF-1000XM6 vs AirPods Pro 3. Which Bluetooth headphones to choose based on your tastes and needs

by

Buying good Bluetooth headphones can be a daunting task. There are many models from different brands, so it is difficult to choose if we are not clear about what each one offers. Now that the Sony WF-1000XM6What better than to put them face to face with the AirPods Pro 3 from Apple. Let’s see what their most important differences. The differences between the Sony WF-1000XM6 and the AirPods Pro 3 A clearly differential design Do you like stick or earbud headphones better? Not all people are attracted to the same design, so here we find the first big difference: the Sony WF-1000XM6 have a button design, while the AirPods Pro 3 have a stick format. In this way, they maintain the design of their respective previous generations. In any case, beyond personal tastes, we find two models of comfortable headphoneswhich are designed to be used for hours without fatigue. Both come with their respective pads, which allows us to have a better fit in the ear. Of course, while Sony headphones come with four ear pads, in Apple headphones we find five. The sound section This point is one of the most important, especially due to the compatibility of some technologies. The Sony WF-1000XM6 supports LDACa codec that offers wireless streaming of music in high resolution and that we find in a wide variety of Android devices.

Not that with normal use this is a big difference, but you have to take it into account if you want to use them on the beach or near a pool. We also find other differences between both headphones, such as the heart rate sensor that the AirPods Pro 3 incorporate. This is a sensor that we normally see in smartwatches, but that Apple has decided to introduce in these headphones and that works really well. Yeah you usually playing sports and you don’t have an Apple Watch, it can be very attractive. How much do headphones cost? Both TWS Bluetooth headphones are high-end, so they are not particularly cheap. However, Apple’s have been on the market for a while and can be found cheaper.

Madrid had one of the underground labyrinths without more complex GPS. Google and Waze have tamed it with 1,600 Bluetooth beacons

by

We are so accustomed to GPS that, when suddenly disappears, a simple journey can become a headache. It is not that we have lost the ability to interpret the signs of a lifetime, but that the way of moving through the big cities has changed so much that this technology has become indispensable. The M-30 is a good example. Their tunnels form one of the most complex systems in Europe and, for many drivers, entering them is a risk of disorientation. Taking a wrong way and ending kilometers from fate is not a rarity, but an experience shared by both Madrid and visitors. The reason was clear: The GPS signal was easily lost underground and sometimes returned absurd data. Aware of this, the Madrid City Council presented in September 2024 a plan to display electronic beacons with Bluetooth technology. Installation works began in April 2025 And, five months later, The system is already underway. The idea is to continue adding new beacons over time, but the current network already allows assisted navigation to work in the M-30 tunnels. For a road that acts as a real ring ring of the capital, the difference is not less: moving through it should no longer be an act of faith. An aid that comes at the right time Moving through the M-30 not only requires dealing with its tunnel framework: works at critical points such as A-5 or the sales zone, together with the usual congestion, make any waste of time weigh more than ever. Being sure that we are not going to mislead in the middle of the curve or to take the wrong exit is not a whim, it is a way to win minutes and avoid dislikes on a day -to -day basis. ⠀ 1,600 devices have been installed along 48 kilometers of tunnels, with an investment of 141,000 euros. The objective is to reach 2,700 beacons at the end of the year, once the installation is completed in the rest of the underground network. They are low consumption devices that work with batteries, with an autonomy between four and six years, and issue a unidirectional signal without collecting user information. When detecting that signal, the smartphone calculates the position of the driver in real time and keeps navigation activates, even without GPS coverage. The impact on the mobile battery is minimal thanks to the use of Bluetooth Low Energy. A huge impact on daily mobility The M-30 supports the passage of More than half a million vehicles. Solving a problem such as low -ground loss means improving the experience of hundreds of thousands of drivers That depend on this route to get to work time, home or any point in the city. Another key aspect is that beacons do not require additional mobile data or complicated configuration: it is enough to have activated bluetooth and grant permission to the application. The project makes Madrid the European city with the largest network of active beacons and in the second in the world after Sydney. It has been possible thanks to the collaboration between the City Council of Madrid, Madrid Calle 30, Waze, Google and Imalesapi, the company in charge of the installation. The challenge was not minor: The M-30 has a large number of tickets and exitsin addition to especially complex sections, such as the one from the Prague bridge to the Toledo bridge, with two parallel but overlapping tunnels. The Paris Network, with the Tunnels of the Défense and La Péripherique, is also equipped with beacons of this type. And outside Europe we find even better examples: the Lincoln tunnel under the Hudson River in New York, Queens-Midtown under the East River or Hugh L. Carey, which connects Brooklyn with Manhattan. Madrid thus adds to a very small list of cities that have decided to bet on this technology, and does so in one of the most demanding scenarios on the continent. How is it activated on Google Maps and Waze The system already works in the two most used navigation applications, although with nuances. Google Maps: In Android, you have to go to Navigation settings and activate the option Bluetooth tunnel beacons. In iOS, for now, it is not available. Waze: Simply have the bluetooth on and the permits granted. If the user has it deactivated, the app itself will show a notification when approaching a tunnel with beacons so that it can activate it at the time.

The M-30 tunnels are an absolute nightmare for your mobile GPS. Madrid wants to fix it using bluetooth

by

If you have ever crossed the tunnels of the M-30it is more than likely that you have run out of coverage at some point. It is a more serious problem than it might seem, since the direct translation of not being clear what the correct exit ends up generating less fluidity and traffic safety. The Madrid City Council is aware of the problemand has announced the installation of a system that will allow GPS navigation systems, such as Google or Waze, to work properly within these areas. The problem. The M30 tunnels are especially extensive and thick, a terrible combination for the signal of the GPS satellites I can end up going through them. It is more than usual to lose connection when we are inside and, taking into account the importance of real -time calculations for current GPS systems, this ends up translating into a insured malfunction. The solution. From this Monday, the Madrid City Council will begin the installation of a Bluetooth electronic beacon system in order to allow guided navigation while we circulate through these tunnels. “The initiative is based on the implementation of location beacons with the objective of resolving the lack of the inviability of GPS navigation inside the tunnels as a result of the lack of visibility of satellites that allow obtaining a precise and continuous positioning through triangulation techniques.” The City Council itself admits that it is unfeasible to use GPS systems inside the tunnel. So in the absence of GPS, Bluetooth. How will it work. Madrid will locate different Bluetooth beacons inside the tunnels, with distances of 20 to 40 meters between each of them. They will be located on the sides of the tunnel by specific supports. These beacons will issue an identification signal to their own position, something that browsers can use to determine where we are. Because yes, although we are accustomed to using GPS signal, navigation apps can use Bluetooth when there is no coverage. Does not work by default. The problem of this measure is that Google Maps, the most used maps app in Spain, does not allow the default Bluetooth to use. It is necessary to navigate to the Android settings, go to “navigation”, and activate the Bluetooth beacons. In iOS the option is not available, although it is enough to activate the location functions so that it can work.
