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.
