Hello Android users! Jealous of the iPhone 14’s satellite connectivity features? It’s been a few months since then, and Qualcomm already has a similar feature running on Android. Check out Snapdragon Satellite, a way to send satellite messages from his normal-sized Android phone. Unlike the iPhone, this is an actual two-way SMS-style text message, presumably usable for more casual conversations rather than the iPhone’s highly condensed, emergency-only, one-way survey system. . message.
Qualcomm’s solution runs on the Iridium satellite constellation. This is his 25-year-old 66-satellite network that powers traditional dedicated satellite phones with huge external antennas. Qualcomm says this will now work with normal-sized smartphones and normal built-in dedicated antennas. Francesco Grilli, Qualcomm’s vice president of product management, outlined the service, saying that “in most cases” you won’t even need a new antenna. Iridium operates in his L-band, which is 1-2 GHz, the same as GPS and some mid-band cellular services, so the phone already has an antenna for this.
It doesn’t work without new hardware, but Qualcomm does not require major new components and incorporates it into standard RF loadouts. This is a great situation compared to mmWave 5G, which added a large, extra expensive antenna to a cell phone that very few people can use.

Much like the iPhone, skipping the usual big external antenna means dealing with a certain set of compromises. Unlike an always-on cellular connection, when you launch the target app you may be asked to point your phone at an empty spot and wait for a connection. Iridium does away with the voice calls that were possible with traditional satellite phones, this is data only. The connection uses the Iridium protocol, just like a real satellite phone. Grilli describes communication as “closer To 2G [GSM or EDGE] than To This is a classic TDMA (Time Division Multiple Access) setup where one user talking to a particular antenna monopolizes that connection spectrum while everyone else has to wait. , FDMA (Frequency Division Multiple Access) is how all other telephony radio technologies work. FDMA allows higher bandwidth and multiple simultaneous users, but if we’re talking about outer space, it’s difficult .communication.

Qualcomm’s promise of performance here looks superior compared to Apple’s solution. Grilli states, “A full size SMS he can send in less than 10 seconds, and on average he takes 3 seconds.” That’s a very compressed poll message, faster than her 15 seconds on the iPhone for an emergency SOS that’s not a full SMS. The iPhone is in another Globalstar constellation with different characteristics. That his Globalstar constellation only has his 24 satellites covering the world, not enough for continuous 24/7 coverage. As these satellites move around, there is a regular up-and-down rhythm to the Globalstar service that lasts for minutes at a time at a particular location. The Iridium Constellation has 66 satellites, he needs to be in service all the time, and he may not even have to do the “hold up the phone” dance to get a connection.
You’ll probably have to pay someone to access the satellite network. Qualcomm is a chip provider and didn’t want to go into details about ISPs or messaging apps. Just like how cell phones work, texting to 911 (or the equivalent service in your area) is free and without any plans (which is the law). If you’re paying for a premium plan, Qualcomm’s own settings let you use the messaging standard you want, either Bog-standard SMS using your regular phone number, or an over-the-top service (such as WhatsApp). , the operator must understand it. He’s the only one who has to pay for satellite service, and he can talk to the outside world, so some existing standards would be great.
Qualcomm says the service will be available later this year for phones launched in North America and Europe. Hardware support technically starts with the Qualcomm Snapdragon Gen 2 SoC. This has already seen some devices announced, but satellite compatibility seems to be an add-on feature that manufacturers need to plan for. According to the company, several partners are already working on the design. The feature is exclusive to flagship devices, but for now, Qualcomm says it could be built into newer, cheaper chips as well, depending on how customers respond. We are also interested in putting this functionality into cars.
