This is how Radar COVID works, the Spanish application that alerts of coronavirus infections


Starting today, you can download the Radar COVID application in our country, although the authorities recommend that it not be done yet. There is an explanation for it.
Spain already has its own application to notify of coronavirus infections. After months of waiting, from today it is possible to download and activate it on your mobile to receive alerts in case you have been in contact with someone infected by Covid-19.
As they announced yesterday from Business Insider Spain, at the moment you are only asked to download it “if you are an inhabitant, worker or visitor to San Sebastián de La Gomera”. The reason is none other than to use that territory as an initial test space to check its operation: they are going to perform a pandemic simulation to see what the application’s response is on the island’s mobiles.
But how does this contagion tracking app work? In principle, it has hardly changed compared to what has been expected since Google and Apple began working on the project. In our case, the national award has been for Indra, with a budget of 330,000 euros.
Since Google and Apple launched their API, they have been in charge of evaluating which applications meet the requirements before accepting them in their download stores.
The operation is based on the fact that once the application is installed on the mobile and Bluetooth is activated, each device continuously emits encrypted codes that are received by the mobile phones of users who also have it installed. In the event that there is contact with someone for at least 15 minutes and within 2 meters, this will remain in the memory.
Installing the application is very simple, just download from the Google Play Store and accept the two menus that request it. Then it stays on and reports on the situation the user is in. The only options it allows are to turn off the application or report if you have become ill.
If a user becomes ill, they must notify the application and everyone who has been in such a close situation with the patient will receive an alert, although the person’s anonymity will be respected. In this way, those notified can act accordingly and carry out tests to check if they are infected.
It should be borne in mind that the installation of the application is completely voluntary and that it is the patient himself who must notify if he tests positive for coronavirus: everything depends on personal initiative.
Although the application is already available for download in the Play Store, we do not recommend its installation at the moment, upon request that only residents of La Gomera use it.
