How Much Does Fixed Wireless Matter?

You can get a robust debate pretty quickly when asking “how important will 5G fixed wireless be?” in the consumer home broadband market. Will it matter? 


Probably. But it also matters more to some than to others, and will matter even if the net result is installed base market share shifts of just a few percentage points. So there is no actual contraction between cable operators saying “fixed wireless is not a threat” and a few firms arguing it will be highly significant as a driver of revenues. 


Keep in mind that the home broadband market generates $195 billion worth of annual revenue. Comcast and Charter Communications alone book $150 billion annually from internet access services that largely are generated by home broadband customers. 


T-Mobile has zero market share in that market. Taking just two percent means new revenues of perhaps $4 billion annually. That really matters, even if cable operators minimize the threat. 


“Addressable market” is a key phrase. Right now, 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 18.6 to 20 million. To be generous, use the 20 million figure. 


AT&T’s fixed network represents perhaps 62 million U.S. homes passed. CenturyLink never reports its homes passed figures, but likely has 20-million or so consumer locations it can market services to. 


The point is that, up to this point, T-Mobile has had zero addressable home broadband market to chase. Verizon has had 20 million homes to market for that purpose. AT&T has been able to market to perhaps 62 million homes; Comcast 57 million homes and Charter about 50 million homes. 


So T-Mobile and Verizon have the most market share to gain by deploying fixed wireless. And the value will not necessarily be that fixed wireless allows those two providers to “take half the market.” The revenue upside from share shifts in low single digits will be meaningful. 


Some might counter that early fixed wireless will not match the top cabled network speeds. That is true. But it also is true that half of U.S. households buy broadband services running between 100 Mbps and 200 Mbps, with perhaps 20 percent of demand requiring lower speeds than that. 


So even if fixed wireless offers lower speeds than cable hybrid fiber coax or telco FTTH, it might arguably still address 70 percent of the U.S. market.


It is conceptually possible that untethered access could eventually displace a substantial portion of the fixed networks business, longer term. 


Up to this point, mobile networks have not been able to match fixed network speeds or costs per gigabit of usage. But that should change. 


Mobile network speeds will increase at high rates, with a rule of thumb being that speeds grow by an order of magnitude every 10 years. One might argue that is less capacity growth than typically happens with fixed networks. +

But that might not be the relevant context. What will matter is how much speed, at what price points, mobile or fixed wireless solutions must offer before becoming a reasonable choice, compared to fixed access. 


Assume that in its last release, 5G offers a top speed of 20 Gbps. The last iteration of 6G should support 200 Gbps. The last upgrade of 7G should support 2 Tbps. The last version of 8G should run at a top speed of 20 Tbps.


At that point, the whole rationale of fixed network access will have been challenged, in many use cases, by mobility, as early as 6G. By about that point, average mobile speeds might be so high that most users can easily substitute mobile for fixed access.


To be sure, cost per GB also has to be roughly comparable. But, at some point, useful bandwidth at a reasonable enough price could allow wireless solutions to take lots of market share from cabled network providers. 

 

We never get away from debates about “which is the better choice?” in the connectivity or computing industries. Nor do we generally remember that “one size fits all” rarely is the case. Additionally, all choices are conditioned by “when, where, by whom and why” technology must be deployed. 


The global choice of internet protocol rather than asynchronous transfer mode as the foundation for all next-generation networking is among the exceptions. That really did result in an “all or nothing” outcome. 


But few other choices are so stark. Consider access network platforms. Decades ago there were serious--if brief--debates about whether “fiber or satellite” technologies were “better” for wide area networks. There was speculation about whether “Wi-Fi or mobile” was the better platform for phone connectivity.


There were debates about whether fiber to the home or hybrid fiber coax was “better” for consumer broadband access. 


Now there are arguments about whether local connections, unlicensed wide area low power networks or mobile networks are “better” for internet of things sensors. 


Such questions, while valid, always have to be qualified by the issue of “better for whom?” It might not make sense for a public network provider to consider HFC as a foundation access technology. It virtually always is a logical choice for a cable operator, for the moment.


 “At some point,” optical fiber is universally seen as the technology of choice for telcos and other “cabled media” providers. But wireless remains the key approach for satellite, wireless ISPs and mobile operators. 


What is “better” cannot be determined without knowing the “for whom” part of the business context; the “when?” part of the discussion or the “under what other circumstances?” detail. Fiber to the home might be the “ultimate” choice, but “when to deploy” or “where to deploy” also matter. 


U.S. cable operators in 2020 had at least 69 percent share of the installed base of accounts, according to Leichtman Research Group. Telcos likely had something less than 28 percent of the installed base, accounting for share held by independent internet service providers (wireless, fixed and satellite).

Without government support, FTTH might never make business sense, in some locations. In other cases the business case is so marginal and risky that an alternative, such as fixed or mobile wireless, might well be the alternate choice. For a telco, a “fiber” upgrade might make sense when existing copper facilities must be retired in any case, and where need is not driven by revenue upside, merely facilities replacement. 


For a cable operator, an FTTH overlay could make near-term sense to support business customers, but not yet consumers. But fixed wireless might also make sense for cable operator “edge out” operations, and for the same financial reasons that telcos used wholesale as a way to enter geographically-adjacent markets. 


The questions are even broader when looking at total demand for broadband access. In terms of total connections, in the U.S. market 75 percent of all internet access connections use mobile networks. Just 16 percent use cable HFC, while perhaps 8.6 percent of connections use either fiber or copper telco connections, while everything else--including satellite and fixed wireless--represents less than one percent.

The point is, how much faster do untethered services need to be--assuming roughly equivalent terms and conditions of usage and price--before a significant percentage of home broadband users consider an untethered solution a functional substitute for fixed network access?


Matching headline speeds might not matter, as most consumers do not buy those services. Untethered options simply have to be “fast enough, priced well enough” to contend for significant share of the home broadband market.
