FCC Proposes Satellite-to-Phone Rules To Eliminate 'No Signal' Once and For All (techcrunch.com) 43

The FCC has officially proposed, and voted unanimously to move forward with, a framework under which satellites can communicate directly with smartphones in a structured and useful way. From a report: The Notice of Proposed Rulemaking, circulated earlier this month and formally voted on today, is essentially a complete first public draft of what the FCC hopes to accomplish by establishing rules and guidelines around this emerging area of communication. Apple already made the news with a dramatic rescue made possible by its new emergency satellite feature, and companies like Lynk and AST SpaceMobile are working on providing universally accessible two-way data anywhere in the world.

Qualcomm and Iridium are integrating the capability at the chipset level. T-Mobile and SpaceX have said they plan to test their own Starlink-based system this year, and plenty of others are looking to enter the fray. There's still the matter of how this space-based connectivity would integrate with existing systems. Our mobile networks run on very carefully defined frequencies so that phones and towers don't interfere with one another, including satellites, which have totally different frequencies and signal powers.

    It is a simple technical problem. Everyone wears a hat with a dish on it.

    No, there still is not the matter of how this space-based connectivity would integrate. It's called Voice-over-IP and push notifications. They have existed for years.

    These satellite networks are designed to carry internet traffic, so let them do that. Pop a robust VoIP gateway up and call it a day. Then, when 6G cellular comes around, shitcan the separate voice protocols and just use prioritized VoIP there too.

    • Is there any reason in 2023 to have separate protocols for realtime unicast streaming compressed two-way audio instead of treating it like any other data stream on a network that features QoS prioritization?

      Calling emergency services could be one reason.

      Calling 911 (at least in the USA) on a cell phone gets routed similarly to how landlines work, based off a mapping on where that call comes from, a mapping the phone service providers made when establishing service in an area. If that call is wrapped up in VoIP then that gets into the problem of any other VoIP service today. With a static location like the crappy VoIP service I had from Mediacom the location was something entered in some database. If the set

    • Technically VoLTE (Voice over LTE) is VoIP. The reason it's still separated out is money, of course. The cost per kilobyte is second only to SMS.

      I think you're missing the point. The issue isn't the data protocol (ISO layers 3-7), it's the lower level RF layer (1 and 2). You need to sort out what radios to use, what frequencies they're on, the modulation, power, noise filtering, error correction, and the like. You also need to sort out how a voice session gets handed between different radios without glitches (which ought to be a solved problem by now but one never knows).

      Different latency requirements dictate different packet sizes. The telecom people look at a TCP/IP and say that the format is too heavy. Although today, people seem to be quite tolerant of 2 second communications delays. So maybe the old expectations of 10ms latency aren't important any more because it's already been blown to bits.

      That's actually exactly the way VoLTE (and VoNR) works. It's a SIP VoIP connection on a prioritized LTE or NR data session. There is a guaranteed bitrate, at the highest QoS priority (QCI 1) on the network. IMS also works this way, but at a lower QoS (QCI 5). Regular data sessions are not guaranteed bitrates, and are in the QCI 6-9 range. Often tethering is a separate data session at a lower QoS than regular phone data (for example, QCI 6 vs QCI 8).

    Right, so how is this going to work when you are inside or underground etc? No signal is just a tad more complex than not being near a mobile phone mast.

    • It won't work underground, however there are large areas on the country which have no cell reception. I can be in a dead zone in 15 minutes. The dead zone is eight whole miles from the county seat. Mountains are quite impervious to HF radio waves.

      This problem could be avoided with VLF transmission, but the multi-hundred meter antenna needed on your phone might be a wee bit inconvenient.

      Of all the places I've gone camping in the last decade only one had cell phone coverage. I view this as a feature, but if I

    • If you're underground, why would you think there would be a cell signal? Is this a trick question I'm too intelligent to understand?

      Reminds me of the people who go off into the wilderness and bitch they can't use their phone to navigate.

      • > Is this a trick question I'm too intelligent to understand?

        No, legit there are many people who think their phones works in the subway because the signal must be pretty strong.

        It's like they can't even remember before the repeaters went in.

        It's wild.

    • I'm sure that will work great indoors.

      I can recall being in a lecture hall that was deep in the basement of a large stone and brick structure to find that my cell phone could still receive phone calls. I then recalled how my phone and service provider had WiFi calling services. If there is WiFi access to the internet then your phone will likely work indoors like mine does. Presumably large population centers will still have terrestrial cellular service since satellites could be easily overwhelmed in such areas, as well as "micro-cells" in la

  • get ready to roam into an network with high costs while not crossing any borders.

      So just turn of roaming in settings if you think you won't need it, this is great fot rhose rhat need it. It won ' t surprise me if you will get an option to "satellite roam for e-911 only" option rather quickly, and thise calls will ofc be free
      • will there be an satellite roam as it's own setting?
        and there may need to be an fcc rule that some software build can't do an easy button have have any roaming be only one on or off button.

        • by bn-7bc ( 909819 )
          Well ok I referenced the fcc, I should have said fcc or other relevant regulators. Here in Europe it is not yyha uncommon top go abroad, in which case you need roaming to get anny service at all. This was the reason for me suggesting a separate setting for roam via sattekine as roaming is free in most of Europe (specifically in EU + a few other countries) so disabling all roaming would not serve any purpose and in fact create a worse experience than what we currently have. and the option to disable roam
  • I'll try to translate the future message about this, "Congratulations we've completed our sat to phone service to ensure no one never has a no signal issue ever again! Don't worry, to make sure it stays connected, even when your device is off, it still connects. No battery in an emergency? Don't worry it has built in RFIDs that will report your location to the nearest phone that can communicate with the sat phone. It does provide better safety in case of a disaster to track where people might be (This is tr

  • I haven't used or even seen a Starlink handset. I remember Iridium satellite handsets were pretty bulky (think "Gordon Gecko phone"). Have we really miniaturized the radios and antennas enough that a normal-sized phone can communicate with a satellite? How much power does this take (especially compared to terrestrial service)?

    • How many years has it been? Now look up cell phones of the 1980s and 1990s to see the march of tech.

        Five minutes, I can now report. It looks like Starlink base stations use an antenna which is about a quarter to a half meter square. Definitely not something which fits in a phone, not yet. Was there some other technology the FCC was thinking about?

        Nice but that wasn't exactly my question (although, proof by demonstration, it can be done).

        This article [zdnet.com] gives an overview of what an iPhone can do. Yes, the antenna is built into the phone, something I didn't realize was possible. It's pretty limited for now but one can imagine that improving. I'm kind of curious how much power it uses versus a cell signal and what satellites it can use.

        This is clearly on the technological cusp. It seems a good idea to start setting interoperability standards now, or at l

  • Better hurry before Apple makes it only work with their proprietary shit.
  • I guess that this means that you'll have to turn your phone off, or take the battery out ( if there are still phones that can do that ), or resort to a mylar bag or metal box if you want to go to a protest or don't want to be tracked anywhere in the world by someone you've pissed off.
