We have some spots here in Martorell (25km away from Barcelona). Really handy for those public places (like the public gym), as the mobile coverage is not great at all there (strong shadow zone, for whatever the reason).

You don't need authentication: you accept terms of use, and you are good to go. Also, there is a cap in the amount of data that you can use each day (based on MAC, I guess), but it is generous enough to allow me to stream for youtube from one hour at the gym, or to work for two hours when I'm in the mood of doing it from the garden near the swimming pool.

A friend of mine told me that the EU is paying the local administration for the equipment and installation, but there is an explicit condition in the contract that blocks any kind of personal tracking.

So I would say this is a neat project. And 120M€ for an entity of this size doesn't look like an extraordinary amount of money.
