T-Mobile and Sprint Are Talking Merger Again — And 5G Is the Reason

T-Mobile and Sprint are at it again. Reports today indicate that the two carriers have restarted merger talks after their 2014 attempt and a 2017 negotiation both fell apart. The deal under discussion is valued at roughly $26 billion, and the rationale this time is one word: 5G.

Both companies argue that the massive infrastructure investment required to build out 5G wireless networks justifies — even requires — combining their resources. Critics argue that reducing the U.S. wireless market from four major carriers to three would devastate the competition that has driven price cuts and service improvements for the past five years.

This deal matters for home broadband as much as for cell phone service. Here's why.

The 5G Pitch

5G is the next generation of wireless technology, promising peak speeds of 1 Gbps or more, latency under 10 milliseconds, and the capacity to connect billions of devices simultaneously. It will eventually power everything from autonomous vehicles to remote surgery to industrial automation.

For broadband consumers, the most relevant 5G application is fixed wireless home internet. Verizon has already announced plans to launch 5G home broadband in 2018 in select markets. The pitch is gigabit-class internet delivered over wireless instead of fiber, potentially bringing fast broadband to areas where running cable is too expensive.

Building 5G networks requires enormous capital investment. Cell sites need to be more numerous and more closely spaced than 4G sites because 5G uses higher-frequency spectrum that doesn't travel as far. Backhaul (the connection from cell sites back to the core network) needs more bandwidth. New equipment, new spectrum, new fiber connections — the buildout costs run into the tens of billions.

T-Mobile and Sprint argue that neither company can afford to build a competitive nationwide 5G network alone. Verizon and AT&T are bigger and have more cash. Combined, T-Mobile and Sprint would have the scale to compete. Separately, they'd both fall behind, and the wireless market would devolve into a Verizon-AT&T duopoly anyway.

There's some truth here. Sprint in particular has been struggling — the company has lost subscribers, its network is widely considered the weakest of the four major carriers, and parent company SoftBank has been looking for an exit strategy for years. Without a merger, Sprint's long-term viability as a standalone fourth carrier is genuinely uncertain.

The Competition Concerns

The opposing argument is just as compelling. American wireless consumers have benefited enormously from having four competing carriers.

Look at what's happened since the 2011 attempt by AT&T to acquire T-Mobile was blocked by the DOJ:

Unlimited data plans returned. T-Mobile launched genuinely unlimited plans in 2016, and competitors followed. Five years ago, "unlimited" meant 2 GB and then throttling. Today it actually means unlimited.

International roaming improved. T-Mobile's "Simple Global" plan included free data roaming in 140+ countries. The other carriers responded with their own international plans.

Two-year contracts died. T-Mobile abolished mandatory two-year contracts in 2013. Within two years, every major carrier had followed suit.

Phone subsidies were unbundled. Customers can now buy phones outright or finance them separately from service plans, making it clearer how much they're actually paying.

Prices fell. The cost per gigabyte of mobile data has dropped dramatically since 2013, driven primarily by competitive pressure from T-Mobile's "Un-carrier" strategy.

Almost all of these improvements were initiated by T-Mobile, the smallest of the four major carriers, and adopted by the others under competitive pressure. T-Mobile's role as the disruptive challenger has been one of the best things to happen to American wireless consumers in years.

A merged T-Mobile-Sprint would still nominally compete with Verizon and AT&T. But the dynamic that's driven five years of consumer-friendly changes — a hungry, smaller carrier desperately trying to win subscribers from larger competitors — would be gone. T-Mobile-Sprint would become the third member of an oligopoly, not the disruptor pushing the oligopoly to behave better.

The Home Broadband Angle

Why does a wireless merger matter for home broadband? Because 5G fixed wireless is shaping up to be the most credible challenge to cable's dominance in home internet that we've seen in years.

The wired broadband market is essentially a cable monopoly in most American markets. DSL can't keep up with cable speeds. Fiber is available in only a fraction of homes. Most consumers have one real option for high-speed wired internet, and that option is cable.

5G fixed wireless could change that. If wireless carriers can deliver 100 to 1000 Mbps over the air, they become a real competitive alternative to cable. The cable industry has had decades to prepare for this threat, and the prospect of credible wireless competition is one of the few things that might actually push cable companies to lower prices and improve service.

For 5G home broadband to succeed, you need carriers willing to invest aggressively, undercut cable pricing, and target underserved markets. Four competing carriers create more pressure to do this than three. Combining T-Mobile and Sprint makes it more likely that wireless 5G home internet becomes a comfortable third option for the wireless carriers, priced to make money rather than to disrupt the cable industry.

The death of T-Mobile as the disruptive carrier could be the death of 5G home broadband as a real cable challenger.

The Regulatory Path

The merger faces review by the FCC and the Department of Justice. The political environment is more favorable to mergers than it was in 2011 when the AT&T-T-Mobile deal was blocked, or 2014 when the first T-Mobile-Sprint attempt collapsed.

Ajit Pai's FCC has been generally favorable to industry consolidation. The Trump administration's DOJ has signaled mixed signals on antitrust — it surprised many observers by suing to block AT&T's acquisition of Time Warner, but its general approach to mergers has been less aggressive than the Obama administration.

Whether T-Mobile-Sprint gets approved depends on the specific antitrust analysis the DOJ applies. A traditional analysis focused on the four-to-three reduction in the wireless market would likely lead to rejection. An analysis that accepts the carriers' 5G investment argument and considers the broader competitive landscape could go the other way.

What to Watch

Spectrum holdings. The combined company would have one of the largest spectrum portfolios in the U.S., particularly in the mid-band ranges critical for 5G. Regulators may require divestitures.

Postpaid vs prepaid. Sprint's Boost Mobile and T-Mobile's MetroPCS together dominate the prepaid wireless market. Combining them would significantly reduce competition for cost-conscious customers, who often have fewer alternatives than postpaid subscribers. Expect divestiture pressure here.

Job impact. Merger talks always include claims about synergies, which is corporate-speak for layoffs. The combined company could shed tens of thousands of jobs as duplicate retail stores and operations are consolidated. Politicians worried about job losses are a wild card in regulatory approval.

Rural coverage commitments. To win approval, T-Mobile and Sprint will likely need to make specific commitments about rural network buildout. Expect pledges to bring 5G to underserved areas — pledges that will need to be enforced after the merger closes if they're to mean anything.

This deal could go either way. What's certain is that the competitive dynamics of American wireless — and indirectly, American broadband — are about to change. Whether they change for the better depends on whether the regulators force enough conditions on the merger to preserve the consumer-friendly competition that's defined the past five years.

T-Mobile spent a half decade as the wireless industry's chaos agent, dragging the carriers into more consumer-friendly territory whether they wanted to go or not. If this merger goes through, that era ends. The question is whether 5G is worth it.
