AT&T, Verizon and T-Mobile pool airwaves for satellite phone service before setting a launch date

AT&T, Verizon and T-Mobile formed a company on Oct. 1 to pool some of their airwaves so ordinary phones can reach satellites beyond tower range. Analysts read it as a defense against SpaceX, while a driver who loses signal on a back road this week has the same options as before.

What happened

  • Paul Roth, a longtime wireless executive, is the company's interim CEO, and each of the three carriers holds a seat on its board.
  • The carriers' press release promises the venture will "nearly eliminate dead zones in the US currently without mobile service."
  • SpaceX has been buying airwaves of its own for a phone-to-satellite service, though the carriers' announcement never mentions SpaceX.
  • The carriers have not given a launch date or a price, and TmoNews reports there is no timeline for results.

Why it matters

  • decision Teams buying phone plans for field crews have nothing new to sign, so satellite coverage for now still depends on which carrier each crew uses.
  • constraint Pooled carrier spectrum may give the venture limited leverage with satellite firms, since according to Phandroid those firms already have the airwaves they need.
  • precedent A single buyer inviting several satellite providers to compete puts satellite firms in the position of bidding for three carriers' customers at once.

A lineman on a county road checks his phone and sees "No Service." Phandroid wrote that the new venture is meant for him: "If you've ever lost signal on a rural road or during a storm, this is aimed at you" [16]. Here's what he can actually do about it this week. If his crew is on T-Mobile, he can text over the satellite service T-Mobile built with SpaceX's Starlink, because the press release says existing satellite deals stay in place [8].

The carriers' release describes what they expect him to have later. It promises that "redundant connectivity will become available when existing ground-based networks are unavailable due to extreme natural disasters or other unusual disruptions" [14]. It also says the service adds to the carriers' regular networks without replacing them [10]. So far the venture is a company without a name [15] and its board. "It sounds like things are still in the early stages," Engadget wrote [13].

The press coverage puts the motive down to SpaceX. LightShed Partners analysts called the venture "a symbolic front against SpaceX" [5], and Engadget named Starlink and Amazon's Leo as the dedicated satellite providers the carriers are likely hedging against [12]. That framing sits awkwardly beside T-Mobile's Starlink-built texting, a product one of the three owners still sells [8]. The spectrum is the weaker piece, since its value depends on satellite firms wanting carrier airwaves on top of their own. According to Phandroid, they already have access to the airwaves they need [6].

I think the venture is built first for the carriers' side of the negotiating table. A single company that works with several satellite providers lets those providers compete for the business, as Phandroid described the design [17].

For whoever manages phones for field staff or writes an outage plan, a 2x2 is enough for Monday's decision. One axis is whether a crew's current carrier already has a satellite deal. The other is whether the problem is routine dead zones on known routes or a ground network knocked out by a storm. Where the carrier has a deal, that deal stays the plan, since the venture leaves it in place [8]. Where it does not, there is nothing to sign until the venture sets a date and a price [7] and identifies a satellite provider [9]. The cost of waiting is that crews without a satellite deal keep the gap they have today. I would recheck the disaster row first when those details arrive, because an outage plan is where the release's redundancy promise [14] matters most to an operator.

What to watch

  • Which satellite provider signs first with the venture, and whether Starlink is among the bidders.
  • Further SpaceX airwave purchases for its own phone-to-satellite service, as a test of whether the carriers' pooled spectrum gives them leverage.
  • Whether the venture's service is folded into existing plans or sold as a separate add-on.
