      fun fact: the term piracy/pirate referring to illegal downloads etc actually comes from traditional piracy.
      Piracy is committing crimes in an area not under any country’s direct jurisdiction, ie. at sea. But because the internet is also not under one country’s jurisdiction, you are technically committing piracy.
      This also means piracy applies to Antarctica, space, and any planet or moon, because obviously no one actually owns or controls these areas.

    I remember Norm Chan from tested talking about his experience on the Captain Klebnikov, an arctic cruising icebreaker. The only way they had to contact the outside world was some kind of shortwave internet connection that could only do text-based email from a specific terminal, and it was tightly rationed, basically you got enough characters to check in with your family and had to remind them to delete the included reply message to save on characters.
    I don't know how much of that was a side effect of it being the Arctic, how much of it was from being Russian, and how much of it was from the ship being quite old.

      The ship was built in 1981, I am not sure if that means it’s old. The wiki page says that it was modernized in multiple times between 1998 and 2016, but doesn’t say whether this included comms. The Arctic does help much either, because communicating with geostationary satellites can get quite hard near the poles. You can use Iridium but IIRC the bandwidth is limited there as well, and it’s expensive. Russian arctic and Far East (where the ship is stationed) is also very sparsely populated which means not that much satellites aim there

    • @AndrejaKostic
      @AndrejaKostic Před 2 lety +28

      @@burnstick1380 Hi! Ex network engineer (now doing medical devices firmware) and shortwave radio enthusiast here! Let me try to clear this up a little bit. It's a bit difficult since a book can be written about every word in "some kind of shortwave internet connection".
      "Shortwave" (or high-frequency/HF as mentioned in the video) in this sense refers to the wavelength of the radio signal, in the 1920s/30s sense, that is to say 3 MHz to 30 MHz (although the higher medium wave frequencies tend to get lumped with shortwaves, so we get the MF/HF term from the video, which is basically 1.6 MHz to 30 MHz).
      The frequency range is important, as the HF frequencies tend to refract off the ionosphere and go back to Earth, allowing for very long range communication: Coastal HF radio stations from China and Australia can be heard with OK-ish antenna systems in Europe. On the other hand, communication on long and medium waves tends to, at most, cover one continent.
      The downside of the shortwave is that the entire frequency range is around the size of one WiFi channel. Another issue is, that the propagation of radio waves is very difficult to predict with certainty, and depends on the time of day, time of year, and the time in a 11-year solar cycle (so you might have to wait for hours, to get day-time/night-time to be able to connect to the station which will receive your e-mails!). Additionally, the frequency range has a very large number of users.
      Therefore, the MF/HF frequency ranges are divided into a number of bands, which are then divided into a number of channels.
      There's a 500 kHz MF band for Morse code, which is today almost completely unused, and a band at 2 MHz, which is similar to the HF bands and can be used for voice and data.
      On HF, there are the 4, 6, 8, 12, 16, 18, 22 and 25 MHz bands for marine radios, which are in turn, divided into 3 kHz wide channels.
      Those 3 kHz channels can be used for either voice communications, radio telex (known under a number of names such as narrow-band direct printing NBDP, SITOR A/B and so on, 100 Baud speed), or general data (modem and PC connected to radio).
      Now finally to the e-mail part...
      As Zoulous mentioned, one way is to send a telex message to a coastal radio station, which then sends it as an e-mail. You get a 1980s-style NBDP terminal running DOS, you type the message on its keyboard, and you send it using the 100 Baud connection over the radio.
      Much of this is really manual, so you'd need to prepare the message, connect to the coastal station using radio, go through its menu (if you ever used BBSes, then those menus seem a bit like that), send the message, then disconnect. Bits are often used to charge, so literally every single character is important.
      The other option is to use data modes. In addition to the NBDP terminal, a software or hardware modem for data transfer might be connected to the ship's radio. Commercial stations, from what I've seen, tend to use Pactor hardware modems, while amateur stations tend to use software modems more than hardware modems. This method is somewhat more comfortable. Instead of having to use the ancient-looking NBDP terminals, you usually use a PC with special software, which looks like late 90s early 00s e-mail clients. You prepare an e-mail there, post it to the outbox, and then, using the ship's radio, connect to the radio station providing e-mail service, and send and receive the e-mails.
      Again, prices for commercial services tend to be high, and transfer speeds low.
      Amateur stations are free, but you have to be an amateur radio operator, can't send any commercial messages, have limited time per day, and your marine radio needs to be capable to transmitting on amateur frequencies, and not all can.
      Data rates can be as low as hundreds of bytes per minute, so again, every character in an e-mail counts. In my personal experience, it can take some 5-10 minutes to connect to a station, check if there are any e-mails waiting for you and send an e-mail with say 3-4 lines of text. It might even be needed to try 3-4 stations, to see which are actually in range, and in some cases, you might even need to wait in queue for the station to free up.
      Finally, marine activity on shortwave is becoming less and less popular, as satellite services spread, but the poles are outside of guaranteed coverage of satellite services which do emergency messages and are part of GMDSS, so commercial ships operating in polar areas must have shortwave radios fitted on them.
      Sorry for the wall of text! :)

      The reason they have problems with satellite internet in the arctic ocean, is because nobody lives in the arctic ocean.. So there's no satellites up there... I mean, there are some that pass by in certain types of orbits.. But the kind that provide internet? Not so much. Could you put satellite internet up that far north? Sure. But it would be more difficult, and therefore cost more than it already does... And satellites, especially the launch part.. Are already ungodly expensive. Plus to have a remotely useful amount of bandwidth, you need multiple satellites. No use spending half a billion dollars on a network of communication satellites when like, a couple hundred people a year might use it. Unless those people would be OK with paying like ..oh 10,000 dollars per megabyte. Lol

      @jandl1jph766 Před 2 lety +16

      This is a very common tactic across all networks. The closer to the endpoints you can manage to move any large data source, the better - both for cost and performance. For things like large-ish files from ordinary websites, your ISP will be operating caching proxies that keep frequently accessed resources around for quicker access. A lot of other files will be served through more specialized infrastructure operated by content distribution network operators. They have their own proxies that do the job more efficiently because they know more about the data they serve. Of course, once you get to streaming services, they are practically forced to do this, as trunk connections between the large operators would quickly get pushed well past their limits if they didn't. The data throughput a service like Netflix or CZcams generates is truly staggering.

      Oh, and any issues with it requires an IT person ( typically not retained onboard) to be flown to the ship. They don't hang about and fly you back when you've sorted the issue, instead you've got to wait for the next heli to take you back which could be days or weeks.

    I made a huge mistake a few years ago when I forgot to turn off my roaming option on my phone and I used a cruise/ferry's connection while using social media. It was my own mistake, but I never got a warning and it was on a small journey between Norway and Denmark. I was used to pay 400 NOK (~40 EUR) a month in Norway for 50 GB data. On the ship, I only used about 0.5 GB of data, but they charged me 150 NOK per MB. So I got a bill of 75 000 NOK. I was naturally shocked and couldn't afford it, but called my operator and they reduced it by 95%. Still expensive! So remember to turn off your roaming or LTE when on a ship and go to the reception to ask for WIFI access.

    Really dating myself - came ashore in 2005... You had to wait till you came close to shore to get cell signal. If you got random signal in the Gulf of Mexico, DON'T USE IT! it was from oil rigs, and the roaming charges were insane. We had satellite email, usually via the data feature on INMARSAT A/B and then M. But it was for family comms only, NO pictures, or other large data files! Voice calling on A/B SUCKED quality wise, mini M wasn't bad. One ship I worked on had an Iridium Phone. That was nice, and cheap.

    When I went on a cruise in 2018, they had an app that let you send messages to the other members of your party for free. I think it was just a small local server hosting the service, so it never needed internet access, thus being free to use while at sea.

    When I was in the Coast Guard we had identical satellite dishes for TV (receivers only of course) on top of the ship. We had a computer program that we could put our position in to and it would give us steering angles that would result in blocked reception from the mast and other gear. When football games were on, or other things that the captain/crew were particularly interested in watching, it was an absolute fine art to finding courses that kept the ship stable enough but also didn't block reception. (Note: we spent a lot of time patrolling certain areas so within a huge area we were free to pick a course and speed.)

    Great video, nice clear description. Most ships will use a multiple WAN system with the Vsat (Very-small-aperture terminal) usually being the primary gateway. Or on larger vessels, multiple Vsat antennas (golf ball domes) using a mediator connected to a single modem. This helps with potential blockage issues from the vessel superstructure such as funnel casings or masts etc. A second WAN may be an LTE connection if the vessel stays close enough to shore. But a second or third WAN would usually be in the form of an iridium L band solution (low earth orbit satellite) such as Certus. This is the only true global coverage network as apposed to Vsat Ka, Ku and C band which are regional. L band connections are more stable and less prone to interference from atmospheric conditions such as rain. Rain fade can greatly attenuate a Vsat signal, although the rain storm causing your poor connection may be hundreds of miles away depending on the elevation angle of the antenna in relation to the position of the satellite! An L band connection has a much smaller throughput compared to Vsat (iridium certus around 2mb CIR .5mb MIR). It can be used for essential connections such as ships Email and remote out of band access to the system by the service provider to diagnose and repair faults when the Vsat connection is unavailable.

    Managing Maritime ICT & SatCom for a living - great vid! Your descriptions were spot-on with essential info, as they should.
    FYI, all broadband-level systems and their antennas are collectively known to all crews as VSAT (Very Small Aperture Terminal, which is not entirely correct, but this is for another video...) to be differentiated from other/older technologies & bands like BGAN/FBB, Iridium, etc.
    Also, the Norway roaming message might have to do with the shore-side datacenter that the internet traffic was coming out of - quite possibly Inmarsat, afaik.

    From an IT perspective - there's only one real nitpick (and it's a really minor nitpick) is that Satellite internet can have very good bandwidth (assuming perfect weather conditions) comparable to Fibre at home - so streaming a movie (depending on the link size and obviously the number of people using) is entirely possible.
    The biggest difference is Latency (how long it takes for the request to go from the local device, through the network, up into space and down again, to the internet and back) - for a Fibre connection - going NZ to UK, it's about 300 ms, whereas for a Satellite connection, they are normally 1,000-2,000 ms (depending on factors) regardless of destination - which makes the response of your connection slower.

    Networking wise it all comes down to these parts:

    - Have the computer act as a gateway between those networks
    - Also get a DHCP server so people do not have to setup the network settings themselves (technically optional, but practically needed)

    One other thing that is worth mentioning-the satellites that provide this service are in geostationary orbit, floating above the same spot on the equator, 36,000 km from the earth’s surface. This means that for a message to get from you to shore via satellite, it takes about ⅛ sec to get to the satellite, then ⅛ to get back to earth. Then the response has to go through the same ¼ second trip, making the minimum round-trip time (i.e. the delay you would hear if you said something and a person at the other end responded instantly, or “ping time”) an entire ½ second.
    You mentioned how your phone said “welcome to Norway” when you were connected to on-ship cell service. You may then already know that Telenor is a major provider of marine connectivity, serving not only passenger vessels and commercial shipping, but also oil platforms (particularly those in the Norwegian Sea). When I was on a passenger ship in the North Sea, it did not have cell connectivity itself, but when we got within a few km of an oil platform, often it would get a signal. However, cell network access was restricted only to an allowed set of SIMs (presumably people and equipment onboard the rig). While I could see the network in the advanced mobile network settings on my phone (“Telenor Maritime”, if I recall), I was unable to connect (entirely sensible, because you don’t want an entire boat full of people hopping on your oil rig’s network every time one goes past).
