Networks “are not commoditized and therefore value is a function of price and quality,” argues James Sullivan, J.P. Morgan head of Asia equity research (except for Japan). So it is “value” that ultimately drives usage, capex and opex.
If so, then U.S. telcos have a key choice to make: increase the value of their internet access services to keep pace with cable competitors or lose even more market share.
Back in 2004, cable modem and digital subscriber line internet access speeds were fairly similar (average between 3 Mbps and 6 Mbp), even if cable had a speed edge. By 2006, when cable operators introduced DOCSIS 3.0, cable took a lead it has not relinquished, while DSL only grew speeds a bit.
Still, as recently as 2013, when typical cable modem connections were substantially faster than typical digital subscriber line connections, and by which time U.S. consumers were showing a clear preference for cable modem service, some might still have argued that DSL was competitive, from an end user experience perspective, with cable modem service.
That seems to have changed dramatically in 2014, as cable operators widely deployed DOCSIS 3.0 systems.
To be sure, many would argue that, in some instances (where access lines are short), G.fast will make a difference, closing the performance gap. Others are betting on fixed wireless using 5G.
