Unclear on 4G VoLTE though.Do the 5G physical layers add anything more than MIMO and mmWave? Neither of those really applies. There are some VoLTE changes, but they're back in the IMS network, and mostly make switchover between mobile spectrum and wifi more seamless. I'd be really surprised if LTE wasn't fully supported. (Well, fully supported for text, with voice being on the bubble.)

PARIS — More than 50 mobile network operators around the world have solicited SpaceX Starlink to discuss T-Mobile-type partnerships for direct satellite-to-smartphone services on their territories, SpaceX Senior Director Sara Spangelo said.The apparently unprompted inquiries are expected to lead to agreements with several by the end of this year or soon after, Spangelo said.“We are trying to move as quickly as we can… to get everybody on-boarded so that by the time we offer the service we have regulatory . . .
SpaceX is looking to expand partnerships with mobile operators beyond T-Mobile in the U.S. to provide global services in 2025, SpaceX senior director of satellite engineering Sara Spangelo said Nov. 9.Spangelo told the Connecting the World from the Skies conference in Riyadh, Saudi Arabia, that more than 50 telcos have reached out about partnering with SpaceX to provide direct-to-smartphone services.She said several potential partnerships are in the final stages of negotiations, and expects SpaceX to secure three to five of them by around the beginning of 2023.
After the FCC last week authorized SpaceX to deploy 7,500 Gen2 Starlink satellites, the company yesterday filed a request to put payloads on 2,016 of those satellites for its direct-to-cell system with T-Mobile to enable coverage "by mid-2024."Highlights mine:

NEWS: SpaceX says its Starlink service with T-Mobile will be able to provide voice, messaging, & basic web browsing at theoretical peak speeds of up to either 3.0 Mbps or 7.2 Mbps peak upload (Earth-to-space) & up to either 4.4 Mbps or 18.3 Mbps on the downlink (space-to-Earth).
Important to note that this is *total* bandwidth within a cell, so would be divided among all phones. Starlink will be great for text messages, voice calls & low res pics. If only a dozen phones are active, which is true in remote regions, then video will work.
But the really mind-blowing thing is that this means your phone will work anywhere on Earth, unless blocked by local government!
SpaceX and T-Mobile met with the FCC on January 10th to discuss the Direct-to-Cell application.
On January 10, 2023, representatives of Space Exploration Holdings, LLC and its parent company, Space Exploration Technologies Corp. (collectively,"SpaceX") and representatives ofT-Mobile USA, Inc. (T-Mobile USA, Inc. and its subsidiaries are referred to collectively as"T-Mobile") met with representatives of the Commission's International Bureau to discuss Space's pending application for a direct-to-cellular satellite system that will allow wireless subscribers to switch to satellite service when terrestrial networks are unavailable, connecting the unconnected without requiring them to buy a new device or do anything more than sign up for the service.'During the conversation, SpaceX and T-Mobile provided an overview of the direct-to-cellular system-operating effectively as a cell phone base station in space answered questions from the Commission staff about the application and underlying ITU filings, described the spectrum manager lease notification filed with the Wireless Telecommunications Bureau, and updated the staff on coordination efforts with federal stakeholders.
Next panel up at #SATShow is about sat-to-cell, with:ST Engineering iDirect CEO Don ClaussenIridium CEO Matt DeschSpaceX VP of Starlink enterprise sales Jonathan HofellerLynk Global CEO Charles MillerDesch: "We are very squarely in this satellite-to-cellular conversion space with Qualcomm," with "a whole number of the Android ecosystem" adopting."Plan to evolve beyond just cell" to personal computers, autos, etc."Satellite should connect everything everywhere"Hofeller: SpaceX has a two-fold approach:1 - Complementing terrestrial towers with cell backhaul2 - Go beyond complementing to provide high-speed low-latency service, and a LEO constellation as "best equipped to do that."Miller: We think sat-to-cell "is going to grow to be the biggest category in satellite."Mobile wireless is "a $1 trillion a year industry and the biggest unsolved problem in the industry is mobile hotspots," so "it's a huge opportunity."Miller: "If you can't get the cost of the satellite down, when you're mass producing, to well under $1 million then you're in trouble.""Lynk marginal cost per satellite we have in orbit today is under $200,000"Claussen: "As a ground systems providers, we have to figure out how to distill this" into "a single platform."Moderator: Starlink has 2,500 satellites in orbit? or 3,000?*Hofeller holds up 4 fingers*Desch: "Just say a gazillion"Hofeller: "We're moving rapidly to a world of abundance when it comes to capacity on orbit."Moderator: Is there enough launch capacity?Hofeller: When we were launching Iridium it was once a month, it was unheard of. Now at twice a week, "and it's not crazy to think that the boss will push for more."Desch: "I believe you should follow the money" in terms of the potential of sat-to-cell, "how much has been invested.""Investors are pretty smart, unless they're investing in banks in California, and in the last year or two there has been some investment in this year."Desch: Mobile network operators have not much money behind sat-to-cell, and I believe total investment to date from MNOs in this "is less than $100 million," and "it's probably less than 50."Miller: I "deeply respect" Desch but it reminds me of Nokia's CEO "in about 2005 or 2006 talking about the iPhone.""If you're conservative, you wait too long, and you don't have conviction, ... you miss phase change."Miller: Desch is right that MNOs "are conservative" and "are not Silicon Valley type investors. They're not used to betting risk capital."Hofeller: "We're definitely wrong, we just don't know how wrong we are" about the opportunity. "We're going to learn a lot by doing -- not necessarily by overanalyzing -- and getting out there, working with the telcos."Hofeller: Starlink now has "well over a million users," and SpaceX is building 6 next-generation satellite per day, as well as 1000s of user terminals daily.Hofeller: SpaceX plans to "start getting into testing" its Starlink satellite-to-cell service "this year."
https://direct.starlink.com now states "wherever you may be on land, lakes, or coastal waters."What about International waters, what are the regulatory requirements (if any) to provide LTE or 5G at the High seas?Or is that restriction due to lack of inter-satellite links capacity in general or lack of ISL capability on the direct-to-cellular equipped satellites?Also, will direct-to-cell work from inside an airplane over land?
I suppose EEZ's might be a convenient guide for which countries/MNO's/MVNO's licensing to match with, but deep ocean outside of EEZ's would be weird.Presumably it would be easier for a cellphone in a plane to connect to an airplane internal microcell/picocell that has Starlink backhaul.
SpaceX's latest Ex Parte was created and filed yesterday regarding the ongoing"squabble" with Omnispace over interference concerns."The companies have supported these requests with robust non-interference showings based on both simulations and ACTUAL MEASUREMENTS.There has been torrid debate about whether SpaceX actually launched experimental licensed D2D prototype payloads under German authority with the first V2.0Mini launches 6-1 (Feb 2023) 6-2 (April 2023) several of which had highly publicized early failures and were deorbited. Can you provide "Actual Interference Measurements" without the corresponding spacecraft on-orbit.TIA
To use Starlink on your cell phone, will you need a portable user terminal or will it connect directly to satellites in orbit?
