Business Context Shapes Access Network Strategy

As often happens in any industry, service providers have different opinions about fixed wireless access versus fiber-to-premises versus hybrid fiber coax versus satellite platforms for access services. 

As always, different firms have different views on strategy because of their business circumstances. Perhaps in principle, all former telcos would say fiber-to-premises is the ideal long-term solution where the economics exist. But the economics are daunting in many cases, leading to a “yes, but” strategy that uses other platforms as the economics dictate. 

Verizon has a relatively small “in region” footprint of U.S. homes and businesses--perhaps no more than about 20 percent--and cannot afford to “fiberize” another 80 percent of U.S. homes. So fixed wireless, which piggybacks on the 5G network, makes sense. 

T-Mobile, with close to zero fixed network coverage of U.S. homes and businesses, benefits even more from 5G fixed wireless. 

AT&T, on the other hand, has the biggest footprint of U.S. homes and businesses, so out-of-region coverage magnitudes are correspondingly reduced. 

Comcast and Charter have “homes passed” totals close to AT&T’s footprint and already have HFC networks they believe will be marketplace competitive for quite some time, as multi-gigabit speeds are coming next on the HFC platform. 

Of a total of 140 million U.S.  homes, AT&T’s landline network passes 62 million. Comcast has (can actually sell service to) about 57 million homes passed.

The Charter Communications network passes about 50 million homes, the number of potential customer locations it can sell to.

Verizon homes passed might number 27 million. Lumen Technologies never reports its homes passed figures, but likely has 20-million or so consumer locations. 

Assuming no further significant consolidation, AT&T only “needs” to fiberize within its footprint to reach 44 percent of U.S. homes (and virtually all the homes regulators are likely to allow it to pass). 

Assuming Verizon has no appetite to significantly expand its fixed network footprint, that leaves about 81 percent of U.S. homes that could be passed by the 5G network, and would be impossible to significantly serve using FTTH. 

Comcast already has HFC offering gigabit speeds reaching about 41 percent of U.S. homes. Charter already passes about 29 percent of U.S. homes. Again, regulators are unlikely to allow either firm to get significantly bigger, in terms of homes passed. 

Lumen has a largely-rural territory that includes perhaps 14 percent of U.S. homes, but Lumen has no mobile network assets it can use to offer fixed wireless on a facilities basis. 

The point is that each firm’s view of strategy is shaped by its existing legacy assets. Cable operators, though not denying FTTH makes sense in the future for a growing percentage of customers, also believe HFC is a viable platform, without major reliance on FWA or FTTH to serve mass market customers. 

Verizon and T-Mobile have good reasons for using FWA that piggybacks on their nationwide 5G networks. 

AT&T believes FTTH is the best solution, but also has the largest in-region fixed network footprint of any major ISP, and therefore has the most to lose if copper access facilities are not upgraded to fiber access.

There is no universal answer for “which access platform” makes most sense. Each major ISP has key business model constraints and opportunities that shape the access network choices.
