FTTH is the Platform of the Future, But Might "Always Be"

People often forget that, in the communications business, there is no platform that always is best for every use case. What matters are the particular advantages. In other words, it has proven largely pointless to argue whether mobile or Wi-Fi access is “better.” Both have their contributions to make. 


In the fixed networks business, the belief has been--for many decades--that fiber to the premises is the future of the next-generation fixed network. 


With the caveat that there always is a private interest corresponding to every public policy, one cable TV industry vice president decades ago quipped that “fiber is the technology of the future...and always will be.”


Keep in mind, that was said about 40 years ago. And while North American access platforms have a different pattern than in most parts of the world, 40 years later, hybrid fiber coax platforms have about 70 percent share of the U.S. installed base of broadband connections. 


That creates a huge stranded asset problem for brownfield fiber-to-home deployments. Assuming a new FTTH network is deployed at scale, it might find that up to 70 percent of the assets are not generating broadband revenue. 


To be sure, there is still some amount of voice, but the old copper access network works well enough for that application. Investing capital on FTTH does not necessarily improve user experience, value or features for voice customers. 


For decades, though, there was one clear assumed advantage to deploying FTTH: the ability to sell linear entertainment video. So the basic thinking was that FTTH would allow telcos to hold broadband share while losing voice share and gaining video account share. 


It sort of worked that way until about 2012 for video services.

But the “voice” part of the model never worked well at all, as usage, lines sold and value began to drop in the U.S. market as early as 2000, the peak year for telco access lines and long distance revenue


But business cases matter, and in the U.S. market the business case for FTTH, always difficult, has become quite challenged with the dominance of cable operators, and their seeming ability to keep pushing commercial bandwidths ahead faster than FTTH platforms. Already, at least 80 percent of U.S. homes have the ability to buy 1 Gbps internet access service, provided by cable operators. Not even most telco FTTH networks can do that, yet. 


Nor does it seem likely the cable cost advantage can be overcome any time soon, as technologists already are working on ways to boost HFC bandwidths to 10 Gbps or beyond, symmetrically. Sure, FTTH can do that as well, but not at the cost per home that HFC can provide. 


And that leads to telco interest in fixed wireless access, using 4G and 5G. The issue is not whether “fixed wireless can match FTTH” in potential speeds. The issue is whether fixed wireless can create a positive business case in areas where a new FTTH build is not financially feasible


Globally, matters can be quite different, as it often seems as though only one nationwide broadband fixed network can be supported. Still, in many other countries a mix of platforms is called for, based on home density. And then there is the matter of how people use the internet. 


By 2020, mobile accounted for more than half of all of Internet access revenue in more than 75 percent of countries, researchers at PwC said early in the year. Some analysts noted mobile Internet access revenues already had surpassed fixed network broadband revenue as early as 2013 or 2014.


That trend is expected to continue. By 2024, consultants at PwC say, mobile revenue will account for 68 percent of global Internet access market revenues. In other words, more than two thirds of all internet access revenue globally will be generated by mobile internet access.

FTTH is, in many countries, perhaps always the next-generation platform. In some countries, though, a mix of platforms is likely for decades. In a few countries, FTTH seems to be infeasible for consumer accounts, if deployed by telcos on a ubiquitous basis. Hence the interest in mobile access, or mobile network fixed access.
