How Much Will 5G Cost in Europe?

McKinsey consultants believe 5G infrastructure costs could increase between 60 percent and 300 percent for some European mobile operators, at peak.

Some estimates of spending in Europe to build 5G networks, which have capex estimated at $300 billion to $500 billion.

But other estimates suggest building 5G in Europe might cost less than $60 billion.
