McDonald's was originally a precursor of the popularization of Hotspot WiFi in cafes and restaurants in Paris. Today, the majority of the Mc Donalds have a WiFi supplied by METEOR Networks.
Indeed, it is not uncommon to find in the morning or afternoon 5 or 6 laptops open in theaters these restaurants. A delight for Parisian students (2/3 have a laptop) and a very good choice for McDonalds
that fills his restaurant outside of meal times and thus increases its turnover.
