5G capacity abundance, flat Capex = paradigm shit. Comments from Finnish Elisa's consumer business VP under the article "what makes these [volume-based] pricing ideas profoundly unsustainable".

The state of 4G pricing, mobile data usage, spectrum usage, network capacity utilization and fixed-to-mobile broadband substitution. After its comeback in 2016, in 2017 unlimited mobile data goes viral and spreads to 22 countries. And while in competitive markets such as France and Denmark consumers can buy 100 or unlimited gigabytes for less than €30, in tight mobile oligopoly markets such as Portugal, Greece and Hungary €30 hardly buys any gigabytes. Europe’s mobile data divide widens further: 200x more gigabytes for €30 in smartphone plans, 600x more gigabytes in mobile broadband plans, 200x difference in median gigabyte prices, 40x difference in mobile data usage per capita and spectrum usage.

In March 2017 Telefonica O2 Germany announced 3.5 GHz (they have 83 MHz) Massive MIMO (= very high capacity LTE macro sectors) field trials with Huawei for wireless home broadband and 4K video. Our models predict that O2's macro site grid and spectrum resources (FDD+TDD) could allow it to drive fixed-to-mobile broadband substitution in Germany by connecting millions of households with HD TV service on its high capacity LTE network.

When LTE base stations are upgraded to 'Gigabit' speed the gigabyte volume capacity of the networks also greatly expands. We modelled LTE network capacity based on existing FDD and TDD spectrum holdings (and potential acquisitions in 2.3 and 3.4-3.8 GHz bands) and sizes of the macro site grids. Without and with Massive MIMO in the TDD bands. Topical for operators contemplating fixed-to-mobile broadband substitution ahead of upcoming 700, 1500 (SDL), 2300, 3400-3600 MHz spectrum auctions.
