You are in the middle of a call, suddenly. You look at the coverage bar: zero. You are trying to send a message on WhatsAppBut it is not provided. You restart the mobile. Nothing. Then you look at the next door, watch it watching videos, travel through networks or upload stories like the thing is not with him. How could it be?
Spain collapsed during the best mobile blackout Last Monday, Millions of people Anminigado. No calls. Without the Internet. No access to basic services. But not everything. Some users, within the same building, continued to use their phones with total nature, even with the same city or the same operator.
This scene was repeated across the country. Two people, next to each other. Network -free network. To work with data. Same operator, different results. Great question: Why?
It is not accidental. Mobile network is more complicated than appearing. There are many factors that explain why some people are out during darkness, not others. If you are an attached antenna, the mobile type you use or if you travel before cutting.
Next, we review the keys to understand why the big court does not affect everyone equally.
Failed in the center of the network, not in antennas
In a regular fall, it is normal for concrete telephone towers to fail, so users who depend on them are not identified. But this time it doesn’t: The problem came from the central system of the network center.
This nucleus is responsible for managing the data and calling the transport, and ‘registering’ the equipment that connects to the network. If it fails, even if your mobile is technically covered, it is like that you don’t have a computer: You can’t call or receive data.
That is: It is important that your mobile is attached to any antenna. If the tower fails – by the concentration or by the electric cut on Monday – be out. Very simple.
Why did some mobiles work?
Because they were already recorded on the network before the fall. That is, if you are using data at that time or have an active session, your connection will be stable for a while.
That is why blackout is very unequal. Some parts are not in total coverage. Others did not notice failure. All of this depends on the nozzle, concrete cell or antenna that manages your link at that time.
Energy Support Towers: The key to maintaining the link
Another determination factor is the position of telephone towers. Many antennas have stopped working because the electric blackout has left them without energy. But the others had sub -systemsLike batteries or generators, which allowed it to follow the operation for a few more minutes.
That little rim is important Thus some mobiles were able to maintain or restore the connection before the system collapsed.
Not all mobile phones are acting the same for network fall
The same operator can be attached to two mobiles with different cells or antennas, with a different amount of load or impact. On the other hand, if you are connected to a Wi -Fi network at home or at work, you are not your operator’s network and you are not looking at mobile darkness because you will lead the alternative network.
The type of mobile also affects. The Smartphones More modern with skill Becomes automatically between different bands (5G, 4G, 3G or 2G) To retain the link if a network fails. No ancestors.
Many old models cannot make that dynamic change, so they completely lose the connection until the service is recovered. That is: If your mobile is the latest, you have been reunited before. If not, it is time to wait.
