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.
