The Federal Communications Commission (FCC) has given SpaceX the go-ahead to launch its direct-to-phone version of the Starlink satellite internet service, in partnership with T-Mobile. This development marks a significant milestone for SpaceX, allowing it to gain a foothold in the US market ahead of its competitors.

The proposal was first announced in summer 2022, with SpaceX and T-Mobile aiming to introduce the service in 2023. Although the launch has been delayed, the regulatory approval is a crucial step forward for the companies. The service will enable T-Mobile customers to access Starlink internet on their phones, using certain wireless bands in close partnership with the terrestrial operator.

However, it's not just a matter of flipping a switch. The companies still need to overcome significant engineering challenges to synchronize phones with a cell "tower" that's orbiting hundreds of miles away and moving at thousands of miles per hour. Despite these hurdles, SpaceX has demonstrated its capabilities, having successfully conducted a video call six months ago. The company also provided emergency services during hurricanes Helene and Milton, showcasing the potential of its technology.

The FCC has highlighted the benefits of the service, including increased access to emergency services in areas where traditional networks are unavailable. This is particularly important for regions affected by natural disasters, where reliable communication is crucial. The FCC notes that SpaceX's provision of emergency services during the hurricanes demonstrates the value of its technology.

There are some limitations to the service, which the FCC refers to as "supplemental coverage from space" (SCS). For now, it must operate as an extension of an existing terrestrial provider, in this case T-Mobile. This is due to differences in regulations governing space-based and terrestrial broadcasting. Other companies, such as AT&T, are also exploring similar partnerships, including a collaboration with AST SpaceMobile.

SpaceX must ensure that its service does not interfere with other services on the ground, while terrestrial providers do not need to worry about potential interference with satellite signals. The company has been authorized to operate its remaining 7,500 approved satellites at altitudes of 340, 345, 350, and 360 kilometers, which is relatively close to the International Space Station's orbit. SpaceX will need to coordinate with NASA for any deployments below 400 km.

Notably, several companies, including Amazon's Kuiper, DISH, Omnispace, and TerreStar, filed objections to SpaceX's applications, likely in an attempt to delay the service. However, the FCC was not convinced by many of these objections, allowing SpaceX to move forward with the necessary remedies.

The implications of this development are significant, with the potential to expand internet access in the US market. While the service's launch date and pricing remain unclear, the approval marks a crucial step toward making "no signal" a thing of the past. The focus on universal access for emergencies and essential services, rather than privileged access for recreational purposes, is a welcome development in the industry.
