3:10 - I have found that having a VPN on while trying to use a ship's WiFi will *often* prevent you from being able to log on. Same with hotels and airplanes. Anyone else have this problem?
Way too long of an advertisement. Going to have to block content from this SPAMMY content.
I was once in the Navy. I was assigned to a cruiser and we had a few of these large radomes on the superstructure. I always called them the ship's deflector shield generators
Watch out for X-wings
I'm just gonna stop watching the video and assume you were right all along
What type of Vessel were you on? Was it one of those Star Destroyers?
@@nfrandom3701 its those A wings you need to watch out for
@@jvigil2007 on a cruiser class star destroyer, the y-wing would be your biggest threat. Proton torpedoes rip a hull to shreds and can take a shield generator offline just as well.
Nerding over.
Does illegally sharing torrents at sea make me a pirate?
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’m a CTO that does some of these things for a living - your overview was spot on and easy to understand. You got the terminology spot on, too. Well done!
Thanks. I appreciate the confirmation.
As a network engineer for an NHS Trust, I agree with Andrew. Your explanation was spot on. I would add that if needs me the captain will have some means od restricting or shutting down the public access wifi and Internet access whilst still allowing essential ship and crew access to WiFi and the Internet.
@@G7OEA just don’t confuse “subnets” with “sub-nets”, you might catch yourself a naval court-marshal. I’ll see myself out now.
I have a question after watching this video you might be able to answer: Do those balls protecting antennas have to be balls? Or can they have other forms, too?
@@jupiterjones3789 that’s not for networking equipment, so not my field of study, but what you’re talking about is called a “Radome” - and yes they can be many shapes. military airplanes usually have them as large discs above the plane, for example. wikipedia has lots of examples.
That sponsor segue was Linus quality. Bravo.
Thanks
Smooth 🤣
smoother, even.
Your deep dives into the world of marine education has inspired me to create a TH-cam channel dedicated to my favorite maritime film: Waterworld! Thank you for always publish such top-tier videos!
Thanks. Glad you have found the content motivating.
Halfahour halfahour halfahour....
Waterworld is an awesome movie.
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.
as a network engineer that sounds kinda weird, not the throughput or the mail thing - which probably was just a way to reduce unwanted stuff - but the short waved transmission, sinc egenerally its a tradeoff between speed and range when we talk about transmission, short waved have a high throuput but a long range and long waved have a low throughput but a long range. So wondering how they actually got any connection in the artic
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
Edit: here’s a news article about the Norwegian cost guard having similar issues thebarentsobserver.com/en/arctic-security/2016/05/old-satellites-will-give-broadband-arctic
@@burnstick1380 you send a radio telex to a land station which convert that telex into a email
@@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
Always assumed they were shield generators.
They are, this videos just a coverup… HES ONE OF THE LIZARD PEOPLE
I thought it was doppler
Fun fact - I had a similar thought, just the other way around.
[Radom on star destroyer is hit and explodes.]
A voice from below the bridge tower: "My internet is down!"
Another voice: "Mine, too."
The first voice: "Okay, it`s an external problem, then."
I am not sure that I will ever be able to unsee this when watching the movie.

Sir! We've Lost Our Bridge Deflector Shield!
I heard once that the big streaming Sites like Netflix or Disney+ have servers on the ships so that you can watch Netflix without paying roaming fees.
This is an common practis by internet providers, so that they dont drown in streaming traffic (At least in Germany)
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 TH-cam generates is truly staggering.
Suprised the hub doesn't do something similar especially on cargo ships. All those lonely men without a woman for hundreds if not thousands of miles in any direction.
@@TeaInTheMorning-we2kh who's to say they don't? ;)
I'm sure all the traffic in the ship is fed through a fat caching system. There's bound to be a massive amount of overlap between the sites that the passengers are accessing.
@@KirtFitzpatrick perhaps on cruise ships, but container ships, bulk oil ships etc have a very basic network setup with throttling for the sailors. The other usage for the Internet is monitoring of ship metrics like engine health, fuel consumption etc. The ships owners are tight and want the most basic for the least cost.
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.
Your phone will use the cruiselines Maritime network which is absurdly expensive. Regular bandwitch via satellite that you hook up to via WIFI technically doesn't cost much. But cruise lines have a bad habit of overcharging people because they can.
I have just realized that I should go on holidays on ships to get away from "connectivity". Is there wi-fi? Perhaps. Can I claim "I didn't receive your message because I was on a ship"? Most definitely yes
It was pretty nice when I did it. On some ships, like mine, you only have an email so it's kind of like sending letters.
Ah yes. Plausible deniability. The BEST kind of deniability!
On my first cruise I wanted to see how long my cellphone would manage to have celluar coverage from the shore. I was not aware that ships have their own mobile neworks and I accidentaly managed to rack up 150 eur of data roaming charges within an hour or two.
Nice
Buttery smooth sponsor transition there! Also, I used to live in a city that got a decent amount of cruise ships. It was hilarious to see the crowd of teenagers on their phones as soon as they got off the boats into the nearest free wifi hotspot. All of them bored and cranky, presumably because their parents didn't want to pay for their use of social media while on board.
Sad thing is they'll regret wasting what could have been a great memory bitching about not having internet.
@@TeaInTheMorning-we2kh yup, but that's kinda what being a teenager is about, isn't it? Making mistakes, then growing up to look back at how stupid you were.
I don't think I'll ever go on a holiday cruise, but this taught me to not bring teenagers if I ever do! Or to be ready to pay for internet so they can put content up on whatever has replaced tiktok by then.
I gotta say, this video is such a good fit for a VPN ad that I aint even mad seeing it sponsored by Nord!
Also, I love your vids. In my mind, you are the Civillian Drachinifel.
Thanks Ryobi
A very clever way to mention your sponsor while still in context. Nice 👍
Thanks Moch.
Ships have giant balls because they go to the heartless sea with a mission to take passengers safely and this mission takes a long amount of time and dedication. That is why they have massive kahunas.
The smoothness of how you shoved that ad down my throat was impressive
I have never thought about ships but I was wondering about the WiFi on airplanes and I assume they use the same (or similar) technology. So another week with another piece of knowledge! Thanks for that!
Also let's take a moment and appreciate the awesome animations! Sometimes I have the feeling that it takes more time to do the animations rather than collecting the material for a video. :)
Thanks Stanimir. Most of the information comes from my personal experience, simply because it gives me more time to focus on the animations.
Look for a Captain Joe youtube channel, he is a professional airliner pilot and he has a video about WiFi on airplanes
as a network engineer i can tell you that yes they might communicate with satellites but if they fly over land they - i think - just connect to the normal cell service since their ranges are good enough (up to 40km)
The word is aeroplane
Small Planet Airlines happened to use an internal network with an entertainment application running on server located somewhere on board. Airlines providing Internet connection usually use SATCOM too.
When I was in Iraq in '05 with the US Army, we had one deployable earth station for *all* our military telecom requirements - Internet, VOIP, landline, etc. During duty hours, between 8 and 5, data speeds were atrocious since everyone was on and online. Before or after, it was fine.
When I was in the military we had wifi on a camp. And for some reason, at the same time every night, maybe 02:00 or 03:00. The data speed got really slow or cut out all together. It happened too routine to be coincidence. I always wondered what secret stuff the comms guys were transmitting and receiving then.
War criminal
@@jamessheppard4372 pray tell, how does my time in Iraq make me a "war criminal" or guilty of war crimes?
6:05 There's no reason they can't drop connectivity for the passenger data network while keeping connectivity for ship systems. There are benefits to and security reasons why you would want this traffic segregated virtually too.
Vsat is a trunked solution. The customer can define trunked Vlans for crew and business data keeping them separate. Most systems will also use an L band solution for out of band service for business data and diagnostics only when Vsat or LTE is unavailable.
That has got to be the smoothest segue into an ad I've ever seen.
Never spent a minute on a ship or any boat bigger than a row boat but this channel is always interesting and I love your animations!
Keep up the great work.
Would love to see a video on the typical (if there is such a thing) hierarchy of a ship's command - from small vessels, to lakers, to giant cruise ships. Would be very interesting.
I'm from Shetland but live in Aberdeen, and the twin sister ro-ro ferries that sail between them, the Hjaltland and the Hrossey, have Wi-Fi capability. However, they're both rather slow, and it's worse in the cabins 😒 they also used to have a data usage limit, but I'm not sure if they still do, plus with it being an overnight ferry the limit would renew itself at midnight.
*What a smooth ad transition!*
That was one of the smoothest and most natural transitions into a sponsorship ad that I’ve ever seen! Good enough that I didn’t even fast forward past it
It was really unexpected to see a hometown port in your video! With love from Odesa, Ukraine❤️
That segway into the Nord ad was super smooth. The setup for it was perfect, and I did not expect an ad going into it. That was amazing
I've been struggling badly lately with depression and anxiety and your videos not just entertaining but so helpful in so many ways thank you so much ☺ ♥
also very educational and easy to understand ☺
@@davewright9921 hey 👋
as a radio nerd this video was twice as interesting to me
That was a SMOOTH ad transition. Only saw it coming at the last second.
Neat that you go into some substantial depth of who communication was handled before internet, especially as an educational channel for those who may work on a cruise ship. In an emergency, it's always important to know your backup options should something fail.
Not what I expected when I read the title but this is a great video 😃
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.
Can we just appreciate how seamless the transition into the sponsor was? That is the cleanest sponsor segway I have ever seen
I was just about to say that was a smooth transition Casual. Lol
Thanks CJClarke
@@CasualNavigation Hey btw man. I absolutely love your videos. I personally am a pilot and flying is my love, but maritime is so similar. I do love boating recreationally and your videos are so interesting and informative! Please keep it up!
heheh, i went on the cruise ship you used in this video, the Pacific Jewel. R.I.P 1990/2020. luckily the sister ship, Pacific Dawn is still alive and is actually getting refurbished.
That transition into the sponsor portion was smooth and in this case informative.
That transition into the sponsored segment is smooth as silk.
This was the smoothest transition into a nord vpn ad i have seen in a long time, gg
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.)
Simmers 😒
Every time I watch your videos, I learn something new. I never knew those balls had satellite dishes inside! I thought the whole was was one gigantic, weirdly shaped antenna or something, but now I know what it is!
Perfect transition to the sponsor, well done sir! And great video as usual.
He does not post everyday but when he does I always watch
Thanks maxx1991
One of the many questions I always loved to know about.
That sponsorship transition was SMOOTH
One of the few channels where I have the bell on. Always look forward to your videos mate.
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.
Another superb example of a crystal clear explanation. Thank you. That was very interesting and useful.
Love your videos! Been watching for a while and I just passed my exams for my 100 ton master ticket!!
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 saw the welcome too Norway part i instantly thought about Norway Merchant Fleet which is surprising large.
Could you make a video on specific systems on board different ships?
I'd love to get an in-depth understanding of what the crew uses to navigate, communicate and "read the weather" etc.
Love your videos!
A great video as always 👌
I should add though, newer ships have super fast satellite WiFi that you can easily stream 4K movies on Netflix through. On a recent Sky Princess cruise I was getting >400mbps in my cabin. And with some lines like NCL and Princess you can pay a small amount for unlimited WiFi throughout your cruise.
400mbps satellite internet ? you kidding 😀
@@abdull8736 nope! :)
@@fueledbyregret is this even possible? what satellite communications can Push 400mpbs? you have name for that company?
@@abdull8736 check out the new Princess Cruises satellite setup. They connect to upwards of 12 satellites in different orbits at once.
I’m not messing around. I was on their new Sky Princess in August and the service was insane.
What was the latency? I know Star Link brags about having under 150 ms of latency.
Your videos never disappoint. You really deserve more subs! Keep it up Sir, and thank You for that education
That segue into the advertisement was smoother than my boss' segue saying I have to work the weekends
I have to admit this was the smoothest NordVPN sponsor I have ever seen
I've been impressed with the capability of those systems. Early this year two acquaintances were at sea, one a coworker on a client aboard for data systems work during a repositioning cruise and the other signed on to a cargo ship, both operating near the equator. Impressively the coworker joined MS Teams video calls for work with good quality audio and decent video (when displayed on my 27' screen) and the friend got a video message through.
WIT? recognize your avi haha
thas actually realy interseting! i always mined about like lifeboats and historicall disasters, sometimes even about the gravity center like all about ships. but this, i never even tough about it. thanks for the video
Thanks jelly!
That transition to a sponsor add was as smooth as butter 👌
I like how Cunard had to specify that yes, they do have WiFi on their website
Nice video. The chart at the end got me interested in what video about all the ranks and roles on a ship.
I should've seen it coming, but I didn't. That was the cleanest segway to a sponsorship ad
10/10 video, 11/10 sponsor segue
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.
Cheers!
This sponsorship is inserted well. Well done. 👍🏻
This is pretty cool, I work as a satellite operator in the military, this could be an awesome potential job
That NordVPN sponsor segue was exquisite * chef's kiss *
Hate ads, but this one was seamless
Neat! I always wondered how you got chart updates at sea. Makes sense why they are size-restricted (eapecially in the past).
Which cruise lines have you traveled with?
I remember the CD arriving weeks after the e-mail as well. Always made me chuckle.
@@CasualNavigation Haha, I used to prepare some of those CDs (especially the raster navigational charts) before we stopped doing them.
Im old school when I go to see I cut off comunications, I also bring my own food.
Thank you for another very informative video. I have often wondered about this stuff. Have a good day from Sydney Australia 🇦🇺
That was the smoothest transition to a sponsor that I have ever seen.
As smooth as changing geo-locations on your VPN?
LOL what a nice way to slide in the NordVPN sponser !!
I've seen Star Wars, those are shield generators‼ No way I'm buying some Imperial cover-story about them being communication gear. If you don't take those out first, the Y-Wings won't stand a chance against that cruise liner.
Although sponsor transition was smooth, I have noticed that cruise ships (at least the ones I have been on) blocks VPN connections. I don't know how or why, and would like to know why, but this is thing I have noticed.
“Why do ships have massive balls”

I watched the whole ad with interest thinking it was part of the video subject. LOL
As usual, a very interesting and intense video.
Thanks a lot for sharing this knowledge with us.
Ad seemed seamless
That Nord VPN ad hit me like the Titanic hit the iceberg
We had similar internet access when I was deployed to Kuwait.
Such a great video! Thank you!!!
Nice segue into the advert
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).
Starlink is changing satellite based Internet access for the better. I received my dishy a few days ago and it's awesome! I'm typing this message through it.
You can get these same systems on a 40 foot power boat, they do produce enough electrical to power them. The big issue is the high cost of internet access for a small number of people.
The sat voice costs about $2 per minute and is billed by the minute, so a 30 second call costs a minute of air time.
Thank you, casual navigation, for bestowing upon us the most cursed launch vehicle in internet history: the Atlas-Agena/Soyuz
Best sponsor integration ever. Or is this video just a whole big ad? Inception style.
Haha I'm watching this video while working on a cruiseship crossing the Atlantic from St Maarten to Southampton. 😇😇😇
The ship you used is the beautiful Costa Victoria that just got scrapped due to covid. I used to work on that ship 😔
Full HD video streaming works just fine on Royal Caribbean and Carnival.
Beautiful animation
Networking wise it all comes down to these parts:
- Have a computer with a internet connection
- Have the same computer also connected to one or several local networks
- 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)
# Your home router is just a really crappy computer running a Linux, connecting to three networks (Internet, Wired, Wireless), a modem (for the internet), a DHCP server (for both local networks) and function as a network gateway
That's why I use a Sat Phone when out at sea. I control when and to where I call.
It's over priced for 100mb 10 to 20 dollars .. I m from merchant navy too
Unless you really need it, it is much better to wait for free wifi ashore.

We sail on tankers mostly we use 200mb per month for 20 dollars .we manage that through no root firewall
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.
I would also add rain fade. Rain plays havoc on satellite signals especially in higher frequency bands such as KU and KA.
Amazing animations sir
Glad you like them!
As an IT person I would change only one thing - after you mentioned "Access points" you should add "those are just like your home routers, but only give access to the internal network - routing is done on routers" or something like that - this would make it more clear for less technical people ;-)
I have PhD in telecomunications and I am impressed by your great explanation. Nice job bro
