What is the average speed of a WiTourist pocket WiFi?

Telephone operators indicate the max speed available on their infrastructures, but it is not the real average speed.For reasons related to normal network congestion, the real average speed in Italy is about 5-6 Mbps for 3G standard, and about 15-20 Mbps for 4G standard. Those are average values for Italy, thus the average speed in a specific location can be different from another one. Speeds are practically the same with the main operators in Italy: one operator can offer better performance in a district, but then worse in another one.
