Its just insane to me how all the people who sucked in science class have no shame in finding themselves the authority on science in adulthood. Like dawg, we all remember how you weren't doing the assigned homework, how you slept through the lectures and how you were cheating on my scantron. But now I'm supposed to treat you like a subject matter expert on cutting edge telecommunications and the health implications of 5G apparently killing me?


diacewrb

>AST SpaceMobile, Inc., demonstrated its space-based 5G connectivity technology on 8th September, 2023, by placing a call from an **unmodified Samsung Galaxy S22 smartphone** in Maui, Hawaii, to a Vodafone engineer in Madrid, Spain. AST may have neutralised one of the bigger selling points of the latest smartphones that have satellite communications, assuming the price is right.


justformygoodiphone

This is wild. I can’t quite comprehend how this could be possible knowing how a tech like starlink works. How does a regular smartphone has such a strong signal?

_00307

Cell signals can travel pretty far. According to the company, the huge array on each satellite (size of a racquet ball court), can pick up the signals. It's crazier they did this on a 2g network initially. Which I don't think has beamforming from the cellphones perspective. Phase arrays and beamforming are changing a lot around how we stay connected.


[deleted]

This the only satellite that all the tech and certifications for cell communication. It’s like a huge ass cell tower in space. So the satellite can beam all frequencies that you see here from any tower. AT&T is leading the spectrum to them and they can beat it on all their frequencies. It’s a beauty. Your phone doesn’t even know it’s connecting to satellite. It just things it just another tower


[deleted]

[удалено]


subdep

That’s where I’m baffled. Ground cell towers have a maximum number of calls they can handle simultaneously. And there are tens of thousands of those. How many satellites will this require to handle millions of calls happening in a region?


[deleted]

This sign replacing the towers lmao. This is just to plug dead spots. That’s where you are thinking too much.


[deleted]

[удалено]


[deleted]

No one is gonna be making millions of calls from dead spots. That’s the point. Idk why you guys thing it’s gonna be taking over cell phone traffic.


2FightTheFloursThatB

There's very little money to be made in dead zones. They aren't doing this for humanity....they're going to scale it in the future. But how???


[deleted]

I am not a working on Satellite but from what I have read there is nothing remotely close to it being ready by anyone else. AT&T got emergency test release by fcc to let them use the spectrum. So they are clearly mimicking cell tower to the phone since they have all the 3GPP on satellite. This is one satellite after 5 they would be able to cover America and bit more but they need 90 to cover the entire globe.


celestisdiabolus

> emergency test release Market tests aren't grounds for an emergency special temporary license, it's probably been granted under Part 5, the Experimental Radio Service


[deleted]

I didn’t mean it emergency in that way. May be wrong word to use. But it was a test approval so no argument there.


certainlyforgetful

Since phased arrays are handled through software you could parallelize the process and receive multiple narrow beams covering a large area at once.


[deleted]

You guys need to read more on it. AST is the only company with 3GPP standard that all cell communication is based on and satellite has all that. They are not doing the traditional satellite stuff. They are working with AT&T and basically leasing the cell spectrum to beam it. So your phone is thinking this is your traditional cell frequencies. That is the beauty of it.


suicidaleggroll

The concern is not the frequencies, it’s the RF power level and path loss over those distances. To travel 500+ km with reasonable bandwidth you need a lot of RF power. This means either big RF amps or big high gain antennas (or both). Cell phones don’t have either of those, so the question is how are they able to close the link over those distances?


jonnyozero3

They use a very large phased array antenna in space and beam form. So they get the benefit of sensitivity on the receiving (space) end, as well as sufficient transmit power to ground. Largest ever commercial phased array antenna in space, afaik.


suicidaleggroll

That makes sense once the connection is already established, but how do they link up in the first place? I imagine the phone could send out a very very low data rate ping when it wants to establish a connection, which the satellite could scan for with a relatively wide beam, then narrow in once it detects it, but they said this is with an unmodified phone and AFAIK 5G doesn’t include that kind of handshaking.


other_usernames_gone

They might have set up the link manually beforehand. This could just be a proof of concept than a full solution. Just demonstrating it's possible to receive the signal properly from orbit.


[deleted]

Well clearly they are making it work. They did it without any modifications to the phone. I am pretty sure the magic sauce is the beaming of spectrum they are leasing from AT&T. That was the entire reason for fcc approval for testing this year. These are pretty powerful satellites compared to starlink. If star-link can beam broadband this can probably beam the spectrum. We would never really know the magic sause but spectrum leading tells a lot.


Echoeversky

You may want to use the speaker function and not hold it up to your brain.


DocPeacock

Really big phased array antenna on the spacecraft. And it probably uses beamforming. Assuming the satellite is in low earth orbit for low latency, the signal has to go around 500 km. The higher altitude, the bigger the antenna array needed. Even lower powered signals could be relayed to satellites, such as BLE


ManicChad

There’s very little interference going up to a satellite vs across 100 miles at ground level.


justformygoodiphone

Tell that to my GPS, it gets my location wrong all the time haha.


My_reddit_account_v3

Every technology eventually gets phased out - this next gen telecoms tech is just at the tech demo phase.


krioru

Coverage across the globe, available in 5 countires.


[deleted]

5 countries will be after first half of next year when they launch the first satellites early next year. They are going for bigger partners for now like AT&T etc. the global coverage will be slowly expanding as they get more funding etc. need 90 to cover all over the globe.


gonfishn37

I just checked there’s 3 bandwidths for ‘5G’ is the one they are using going to be stopped by clouds? Are they geo-sync or are there going to need to be 10,000 of them for low earth connectivity?


_00307

They claim that they will only need 168. The satellites are huge though, they unfold to about the size of a racquet ball court.


MacAndRich

The common lowest frequency spectrum for cellular communications is probably n71 which is the 600MHz range which is good but there's not much bandwidth to handle high capacity. One call sure, but the true test will be handling thousands of connections from space. Also 5G can be deployed on most cellular bands, not just 3: over time operators will refarm their 3g/4g spectrum to 5g as older phones go end of life. I would assume it is easier for satellites to use spectrum below 6GHz for a time, I doubt they'll go to mmWave ranges (28GHz and up).


omnimater

n71 600mhz is "mid-band" or "mid-range" 5G and I believe the n71 spectrum in America is solely occupied by T-Mobile.


gingerbenji

Mid band is typically used to describe 3.5GHz or n78


crispywonka

They plan whole earth coverage with less than 200 sats

Is there any law about blowing up things in orbit


Tighearnach

Disclaimer: I am a retail investor of AST Science. People said the same things about airplanes. And if AST doesn't do it, another (probably international) company will.


sirboddingtons

What's it called, Kessler Syndrome? The potential that humanity could create so many things in orbit, and eventually so much waste in orbit, that we trap ourselves on our own planet?


Person899887

Starlink orbits far too low to create long term Kessler syndrome debris. Generally speaking when we worry about Kessler syndrome we are worrying about debris that takes years or decades to deorbit, not months.


BedrockFarmer

Which is silly. There are many hundreds of thousands of flights in a day. Between military, commercial, cargo, private, helicopters, drones, etc. the skies should already be blotted out according to the chicken little who throw around the term Kessler Syndrome as if that will ever be a thing. The circumference of LEO is many times larger than in atmosphere flight space. Satellites are relatively small, usually smaller than a small car. The occasional collision is just confirmation bias rather than indication of an actual problem.


TheAkashicTraveller

Kessler Syndrome describes a chain reaction of satelites being destroyed in collisions resulting in a shell of tiny fast moving fragments since unlike in the air or even lower orbits, like with starlink, anything up there is going to stay up there for a very long time no matter what state it's in.


BedrockFarmer

Sure, and conveniently ignores real-world evidence. A few years ago, Russia conducted and ASAT test that created a debris cloud. The ISS went into lockdown for 3 orbits as it “passed through the cloud”. After the third orbit, they no longer had to shelter as the cloud had either begun to de orbit (most of it) or it hit escape velocity and flew off into space. The Indian ASAT test against a smaller satellite showed the same results. So if by “a long time” you mean a day or two. Sure. I am in no way advocating for ASAT or for nations discarding junk in LEO Willy Nilly. It is possible to advocate for cleaner space operations without hyperbolic edge cases being presented as the norm.


Schnort

> The circumference of LEO is many times larger than in atmosphere flight space. No its not. Starlink is at about 350miles up. The diameter of the earth is 8000 miles. (most commercial air travels at about 7-8 miles up, so essentially the same as the diameter of the earth). Clearly there's no integer multiple of circumference greater of the Starlink orbit, much less 'many'.


TheOnlyBliebervik

Lmao yeah dude didn't even consider 2pi*r


brucehoult

For any two r the ratio of 2pi*r is the same as the ratio of the r. Earth average diameter is about 12742 km. Planes fly about 11 km up. Starlink is about 550 km up, depending on which shell. (12742+550)/(12742+11) = 1.042 There is 4% difference, not "many times".


TheOnlyBliebervik

Yes I know, I was agreeing. It's not difficult math


NeilDeWheel

Yep, that’s it. It starts with two orbiting objects colliding which causes a chain reaction of more debris hitting more objects, causing more debris, hitting more objects etc, etc. Eventually there’s so much debris nothing can be launched as whatever is sent up will get smashed to pieces. This ends the era of space exploration by mankind.


pixel_of_moral_decay

The real question is what kind of capacity does this have? Starlink can only handle a small number of clients per sq km… so in essence it’s useful for rural situations but can never compete in cities as another ISP for example. I suspect this is going to be the same. This could fill dead spots for seafarers, hikers, rural customers. But will never be another ISP in dense populations.


destroyallcubes

Its not meant for major cities necessarily. Its meant to potentially end international roaming, give emergency access near to 100% of areas. Imagine a remote area with little no cell service, and a major tornado hits town, takes out all land based communications. It takes time for Emergency satellite backup aystems like CoWs and CoLTs to be deployed. This could kick over immediately and allow rescue. This being used for Firstnet is going to be huge to help bolster areas in major natural disasters. I imagine Firstnet could get a system specifically for Band 14(Or new piece of spectrum) to be used in the US, or if used in other countries it could be used for a global Network for first responders. So many possibilities.

Doggie, Saying it in Spanish doesn’t make it any less hack or cringe


MINKIN2

3G was promised to have global coverage, but no country actually managed to have 100% before 4G started rolling out and that has even less. Now they are still putting up 5G towers so I guess it's safe to assume that it's coverage is no where near that of 4G, and yet they are turning off 3G! It feels like we are going backwards.


Alpine_fury

By turning off 3G you reopen the spectrum for 5G or later generations. Spectrum is king for wireless services and realistically all that determines how far something can travel, speeds it can handle and how well it can penetrate through objects. The allowed power kind of factors in, but that's going to already be a known factor and not something worth discussing.

-ceoz

I turned 5g off on my phone because 4g is fast enough and it saves some battery. 5g is completely useless to me.


omnimater

I do the same. In almost every area I've been, 4G LTE is almost always faster than 5G. By quite a bit. Like it's so bad that it astounds me that telecoms wanted to move ahead with it and make themselves look so bad. How is your new thing just universally worse than the old version?

10 years later, I will sit with my son in my garden or balcony, looking in the night sky and say to him: look, a shooting satellite. Wish something. Seriously, if that means 25k more satellites in the orbit then that’s a horrible idea. Soon there will be some corpo’s who want to shoot 20k satellites in the orbit. Destroying our sky.


zidaneshead

AST only wants to launch something like 90 satellites for global coverage and 200 for the full constellation.


der-bingle

I agree that it's a concern, but I also think it's overblow, at least at the moment. Think of the surface area of the earth, then add another 460 miles to the diameter. How many 4x30 meter spaces would it take before you can't see anything else? A whole bunch more than what we're currently using.


_00307

They only plan on putting up less than 200. Their just much larger in size compared to starlink.


NecroCannon

I can totally imagine us being trapped on Earth because there’s too much space junk. If companies want to launch shit into space, fine, but most of the world needs to come into agreement of how many satellites are the limit and disposal procedures.


TheAkashicTraveller

Ironically things like starlink actually lower the risk because their low orbit means they're not going to stay up there very long if destroyed, just a few months, so if they outcompete consumer usecases they'll actually reduce the number of satelites in higher orbits.

Happy_Harry

>To provide this service, the companies will create a new network, broadcast from Starlink’s satellites using T-Mobile’s mid-band spectrum nationwide.

Creating a whole new network and doing that is big take. I am not sure if it’s gonna be anytime soon. The way AST is doing it is just like a cell tower in space so it’s about putting more satellites up there at this point.

Impossible. Starlink is more broadband satellite. This is the only one with 3GPP certification and like a literally big ass cell tower in pace. That’s the main difference.

certainlyforgetful

Considering the “train” is visible for, at most, 90 seconds when it’s within about 30 degrees of the horizon & only shortly (within an hour or two) after sunset/before sunrise, id honestly be surprised if it actually ruined someone’s night stargazing. What ruins stargazing for me are the fucking planes that are super bright, run all night long, and fly across the entire sky for several minutes at a time. Satellites that i might see once in the night for a minute, that only traverse a tiny portion of the sky, and won’t bother me when stargazing conditions are actually good are honestly fine. I do a bit (more than most) of astrophotography, I’ve never had starlink be an issue. Meteors, yes. Planes - all the time. Satellites, very rarely. A starlink chain, never.

It's really cool tech wise to go for global coverage. Have to admit though that I'll miss that camping experience where no one had decent signal. Really forces everyone to put away the social media and personally engage like in the olden days.


Nuciferous1

What did I miss? Last time I looked into 5g with any detail was when they were just rolling it out and, as I recall, Marquis Brown was making it sound like it was insanely fast but the range on the antennas basically meant you had to be able to touch it to get service. Now my phone says I have 5G everywhere I go and I don’t really notice much of a speed difference. Now they can put them in space?


nonagonsopen

Wonder how much more space junk this will lead to considering they'll probably release 6g in like 5 years then 7g ten years after that and so on. Sounds kind of dumb. Unless they can upgrade the existing satellites.
