SpaceX to circumvent cellphone towers without any phone modification needed.



Elon Musk’s SpaceX has launched its first set of Starlink satellites to provide cell phone service anywhere in the world, the company announced Wednesday, a milestone the billionaire warned can’t compete with terrestrial networks but will help plug cellular dead zones and boost global mobile connectivity.

Six of the 21 Starlink satellites launched on Tuesday are capable of connecting directly to cell phones, SpaceX said.

They are the firm’s first ever direct-to-cell satellites and are designed to function as “a cellphone tower in space,” according to Starlink’s website.

SpaceX said the satellites will be first used to test its Direct to Cell service in the United States, where the company has partnered with T-Mobile.

Once activated, the service will connect with ordinary, unmodified phones without the need for extra equipment so long as they are 4G LTE-compatible, a standard T-Mobile said covered the “vast majority of smartphones” already on its network back in 2022.
Starlink said it plans to roll out a text messaging service using the technology later this year and broader voice, data and IoT—the network of connected devices called the internet of things—services in 2025.

Musk celebrated the successful launch and said the satellites “will allow for mobile phone connectivity anywhere on Earth.” However, he noted there are limitations to the technology. “While this is a great solution for locations with no cellular connectivity, it is not meaningfully competitive with existing terrestrial cellular networks,” Musk said, pointing to the relatively limited bandwidth that is spread over a large area. Starlink also notes the satellites will let users connect “wherever you can see the sky.”

WHAT TO WATCH FOR​

Starlink ultimately plans to roll out its Direct to Cell service to customers on networks worldwide and said customers would stay “seamlessly connected.” In addition to T-Mobile in the U.S., the company has already announced partnerships with carriers worldwide including Optus in Australia, Rogers in Canada, One NZ in New Zealand, KDDI in Japan, Salt in Switzerland and Entel in Chile and Peru. It is not clear when these services will be rolled out or what specifics there may be on connectivity at home and abroad.

KEY BACKGROUND​

While it has revolutionized how we communicate, wireless technology has its limitations and even highly developed nations have areas where signal quality is poor or non-existent, an area known as a signal dead zone. The issue can be particularly acute in remote areas or those with tricky terrain where geography can make transmitting a signal difficult. Starlink, which hopes to offer high-speed internet service to anywhere in the world and has already used its satellites to connect citizens in war torn Ukraine, hopes to eliminate dead zones by beaming signal down from space.

FORBES VALUATION​

$251.3 billion. That’s how much Forbes estimates Musk is worth. He is the richest person in the world. He leads French luxury goods magnate Bernard Arnault, the world’s second richest person, by around $60 billion. His wealth largely comes from the series of companies he cofounded and runs, notably electric carmaker Tesla, SpaceX (which runs Starlink), brain implant company Neuralink and tunneling enterprise Boring Company. Musk also runs X, an aspirant everything app he controversially acquired as Twitter for $44 billion in 2022.

BIG NUMBER​

42,000. That’s how many satellites Musk has said he hopes will be in Starlink’s constellation. The company is currently reportedly working towards a constellation of 12,000 satellites and reports compiling launch data suggest more than 5,000 were already in orbit by the end of 2023.

Cell phone towers in space could soon be connecting to your normal smartphone.​


Starlink's website update is revealing a bit more about its plans for a satellite-delivered cell phone service. The new page for "Starlink Direct to Cell" promises "ubiquitous coverage" from "cellphone towers in space" that will work over bog-standard LTE. The current timeline claims there will be text service starting in 2024, voice and data in 2025, and "IoT" service in 2025.

Today satellite phone connectivity still requires giant, purpose-built hardware, like the old-school Iridium network phones. If you're only looking for emergency texting, you can also make do with Apple's introduction of the barely there connectivity paradigm, requiring being inside a connectivity window, holding up a phone, and following a signal-targeting app. Starlink wants to bring full-blown space connectivity to normal smartphone hardware.

Starlink satellites with LTE modems will beam Internet directly to your smartphone.

The plan for Starlink Direct to Cell is different thanks to a lot of foundational improvements over what's currently available. First, those other two networks are in a higher orbit: the iPhone's Globalstar network is at 1,400 km above Earth, and Iridium is at 781 km. Starlink currently operates a lot closer to Earth, in the 550 km range. The other major shift is that SpaceX is developing the world's largest rocket, Starship, and having the world's largest rocket means you get to launch the world's biggest satellites. Bigger satellites can involve bigger, more sensitive antennas than what generally are launched into space, and this part of the operation isn't rocket science: Your tiny smartphone will have a much easier time connecting to the closer, bigger satellites, leading to a level of cellular space service that wasn't possible before.
Once the space network gets up and running, SpaceX says the service "works with existing LTE phones wherever you can see the sky. No changes to hardware, firmware, or special apps are required, providing seamless access to text, voice, and data." There will be hardware changes to Starlink satellites, though, with the latest versions sporting the necessary LTE equipment. The new site doesn't reiterate expectations for service speed, but when this project was announced in 2022, the claim was 2–4Mbps.

The page says Starlink satellites with the Direct to Cell capability will first be launched on the workhorse Falcon 9 rocket and eventually Starship. Starship's bigger payload represents a big capability upgrade for Starlink since the full-size "V2" satellites don't fit on the smaller Falcon 9, and today the company is getting by with "V2 Mini" variants due to Starship delays. The 2025 and 2026 service upgrades for Direct to Cell most likely depend on getting the big rocket up and running, so like all SpaceX projects, you should take these timelines with a grain of salt. This whole project was originally scheduled to start a "beta service" this year, but making that deadline now looks iffy.

When the new network eventually gets up and running, SpaceX has several traditional cell phone companies lined up to sell the service. The page lists SpaceX's partners as T-Mobile in the US, Rogers in Canada, KDDI in Japan, Optus in Australia, One NZ in New Zealand, and Salt in Switzerland. The new promo page is seeking additional cellular partners.

SPACEX SENDS FIRST TEXT MESSAGES VIA ITS NEWLY LAUNCHED DIRECT TO CELL SATELLITES

On Monday, January 8, the Starlink team successfully sent and received our first text messages using T-Mobile network spectrum through one of our new Direct to Cell satellites launched six days prior.

Connecting cell phones to satellites has several major challenges to overcome. For example, in terrestrial networks cell towers are stationary, but in a satellite network they move at tens of thousands of miles per hour relative to users on Earth.

This requires seamless handoffs between satellites and accommodations for factors like Doppler shift and timing delays that challenge phone to space communications.

Cell phones are also incredibly difficult to connect to satellites hundreds of kilometers away given a mobile phone’s low antenna gain and transmit power.

Starlink satellites with the Direct to Cell payload are equipped with innovative new custom silicon, phased array antennas, and advanced software algorithms that overcome these challenges and provide standard LTE service to cell phones on the ground.

As the global leader in rocket and satellite launch and manufacturing, SpaceX is uniquely positioned to rapidly scale our Direct to Cell network and will rapidly launch a constellation of hundreds of satellites to enable text service in 2024 and voice, data, and Internet of Things (IoT) services in 2025.
