Fastweb, owned by Swisscom, has announced the first large millimetre wave build (26 GHz) in Europe, intending to cover a third of Italy by 2024. That's actually more than Verizon's plan, adjusted for population. (Italy: 60M; U.S. 328M.) Verizon's current plan is 30M by 2024 to 2027, about a quarter of the U.S. Fastweb expects to deliver a gigabit 500 meters, using Samsung fixed wireless gear and all outdoor antennas. (That's ambitious.)
They are building a better network than Swisscom's own, I believe, which is sub-6 GHz and generally will run at a third the speed of mmWave. Xavier Niel is taking millions of mobile customers in Italy and will soon offer fixed as well. This is a competitive response, one more datapoint that competition, not higher prices, drives investment.
