To which I will add that the spike in investment in 2009-2011 correlates to the availability of AWS-1 (auctioned in 2006, but not cleared of federal users until 2009) and 700 MHz spectrum (auctioned in 2008, not available until analog shut off until 2009). That this spike, when adjusted for inflation, is lower than the spike in wireless investment following the initial PCS auction in 1994 (which was investment entirely under Title II) likewise undrmines the argument that regulatory framwework influences investment decisions.
