AT&T Does a Flip Flop on Fixed 5G, Now Sees It “Unequivocably” a Landline Broadband Replacement - Telecompetitor: “As we look at 5G will you have enough capacity to have a good broadband product that serves as a streaming service for all of your DIRECTV NOW, your Netflix, et cetera?” asked Stephenson in a SeekingAlpha transcript of today’s earnings call. “I absolutely am convinced that we will have that capacity, particularly as we turn up millimeter wave spectrum. That’s where the capacity and the performance comes from and that’s where you’ll begin to see a broad – a true replacement opportunity for fixed line broadband. So I have little doubt that in the three to five year time horizon you’ll start to see substitution of wireless for fixed line broadband.”
The concerns that Stephens expressed last year related primarily to the cost of backhaul to support 5G fixed wireless. Stephens apparently also was envisioning fixed 5G wireless being deployed in the millimeter wave spectrum band. Millimeter wave spectrum will support the highest broadband speeds, but over relatively short distances. Hence there is a need for dense backhaul infrastructure.
It is unclear what has caused the company to have a change of heart about the prospects for an AT&T fixed 5G wireless offering. Interestingly, however, the company recently released a policy paper touting the potential of using its AirGig fixed broadband technology in combination with 5G. Although the paper doesn’t provide details, perhaps AT&T is looking at the possibility of using AirGig to provide backhaul for fixed 5G.
A generation into IP telecom era, AT&T has no proven durable premise service delivery infrastructure easily scalable throughout its service area as its 1990s DSL over copper outside plant goes obsolete. AirGig remains an experimental technology. And the millimeter wave frequencies used by 5G can't penetrate objects.
