That wireless revenue growth has slowed in the developed markets of the world is hardly news. This has been well anticipated and has mostly occurred along the lines of projections of eight plus years ago. The slowing was inevitable because the saturation of mobile devices was unable to continue beyond practical limits defined by local economics. Growth accelerated through 2012 beyond many projections, helped by lower price points of SmartPhones. Multiple-device attach (MDA) rate and data tiers then became the frontline for growth. That growth has scaled back to single digits in the more mature markets but has gained momentum in emerging markets including China, buoyed by rising prosperity and a shift to consumerism.
Europe has hopes for modest growth of higher data rate plans. Coming off of a period of fierce competition that drove down revenue, the industry has whittled down weaker players to a point that recent gains in revenue should continue. Europe and some parts of Asia have led the US market in convergence between fixed broadband and wireless and wireless broadband ICT segments.
The USA has pursued Federal government policy that is among the world's most aggressive in freeing up spectrum for use by converged mobile networks. Capacity is encumbered by cost and local regulation of access to smallcell deployments as well as a less dense and higher cost deployment of fiber optic and other gigabit capacity interconnect. Spectrum availability has grown to a point at which it exceeds that available to operators
Yet America lags much of the world in wired and wireless mobile broadband data rates (speed) despite being near the highest in subscription cost. It is clear that availability of large amounts of spectrum is only part of what it takes to shift the US market into a more competitive worldwide position.
