AT&T to Offer In-Flight Wi-Fi Service

AT&T (News - Alert) now plans to launch a high-speed 4G Long Term Evolution in-flight connectivity service for airlines, as early as the later part of 2015, supporting in-flight Wi-Fi and onboard entertainment, using its existing 4G LTE (News - Alert) mobile network.

Separately, the Federal Communications Commission is considering secondary licensing of satellite spectrum for air-to-ground backhaul in about 500 MHz of existing spectrum, enough to support two suppliers with 250 MHz of total backhaul bandwidth.

At the moment, there are two ways in-flight Wi-Fi is offered to U.S. airline passengers. One approach uses satellite-to-plane backhaul, while the other uses ground-based cell towers.

At least up to this point, that has meant rather limited bandwidth, either because of limited satellite capacity, or a relatively small number of ground-based cell towers.

What is new about the AT&T proposal is the use of the LTE air interface for backhaul, and the potentially massive increase in number of ground-based cell towers that could support air-to-ground communications.

One of the current leaders in air-to-ground services, Gogo, uses only about 180 cell towers, for example. AT&T uses nearly 10,000 tower sites. That provides AT&T with significant potential advantages in backhaul.

What also is financially significant is that AT&T plans to build a new air-to-ground network in the continental United States, based on global 4G LTE standards, without “material” additional capital expenditures.

In other words, AT&T expects to create the new air-to-ground network without any changes to the company’s previously-announced financial guidance. That suggests AT&T believes the expected incremental network cost and operating expenses will be quite slight.

That new service comes within a context of growing perceived demand for in-flight Wi-Fi access and likely new entrants beyond Gogo, Panasonic (News - Alert) Avionics, Row 44, ViaSat and OnAir, with at least two additional expected competitors, should the Federal Communications Commission eventually allow secondary licensing of 14-GHz spectrum to provide such a service.

AT&T might have lots of reasons for believing it has an edge. Today, Gogo only has 3 MHz of backhaul bandwidth to work with, and uses 3G (EV-DO) air interfaces.

All potential users on an aircraft have to share the bandwidth. AT&T, arguably can devote quite a lot more bandwidth than that.

At least one additional factor could be at work. The FCC (News - Alert) is considering licensing, on a secondary basis, about 500 MHz of spectrum that could be used to provide backhaul for air-to-ground communications.

The plan to use existing satellite frequencies first surfaced in 2011, when Qualcomm (News - Alert) asked for permission to use the band for aircraft communications from about 150 ground stations within the United States, enabling on-board Internet access.

But, both developments--the possible new use of existing satellite spectrum, and AT&T’s repurposing of existing LTE spectrum and network, illustrate how competitive a niche market is about to become.

The global market for in-flight Wi-Fi only measures in the hundreds of millions of dollars worth of annual revenue, though some predict revenue could grow to $1.5 billion to $2 billion worth of annual revenue in the near term (by 2018, perhaps).

That is an awful small amount to be gained, on a global basis. But AT&T obviously has concluded that the incremental cost of operating such a business, as part of its 4G Long Term Evolution network, is small, in comparison to the strategic advantages.

Actual revenue earned by AT&T from its public hotspot network likewise is not so large, in gross revenue terms. But the public Wi-Fi network has been an important amenity for AT&T mobile and fixed Internet access customers. An extension of that value to airplane venues likely is deemed important, even if the gross revenue upside is relatively slight.
