Internet from satellite
« on: June 21, 2019, 08:25:02 PM »
In many aeroplane there is WIFI available for passenger wheret it is get internet directly from satellite. But why it is not available for us. Why using BTS tower that needs to dig up the ground for fiber optics connection to work.

Because of the cost and data rate.

It is available.
Quote from: SkyMesh
Enjoy fast, Sky Muster™ satellite internet, for less
Popular Sky Muster™ Plans For example: 50GB $34.95 10GB Anytime Data 40GB Off Peak $0.70 per GB

About the technology
The Sky Muster™ service is designed by nbn co to provide rural and remote Australians with access to satellite broadband including islands such as Cocos Islands, Lord Howe Island and Norfolk Island.

A satellite dish is installed on your roof and connects your premises to the nbn™ network via one of the Sky Muster™ satellites in orbit. An nbn™ network termination device is installed where the cable from the roof enters your premises. This device requires power to operate, and can only be installed by an nbn co approved technician.
In Australia satellite Internet is subsidised for remote regions, hence the apparent low cost.

Maybe try Broadband Hyspeec in the UK.

There are many reasons why we don't use it (at least why the majority of us don't use it. You are free to use it if you want).

One is latency. If you are sending signals via satellites the time required to send the transmission will be much greater. This is especially true for geostationary satellites.
You might not think this is too big a deal, with it being less than a second. (For a geostationary satellite the round trip time is roughly 0.5 seconds for the equator, to a satellite directly overhead), however it is for each transmission. So something simple like loading a webpage through https would take much much longer due to the many transmissions required (first do a DNS lookup, then query the server, possibly getting booted over to https, perform a https handshake (which can take several transmissions all by itself), then finally get the base page data, then send more requests for each element on the page). Would you want to wait multiple seconds, potentially even 10s of seconds for a simple page to load? (note, if using non-geostationary satellites that isn't going to be as big an issue).
This would also make many games impossible to play, and make interactive streaming harder.

One is limited frequency windows. The ionosphere limits what frequencies can be used for space based transmission. This can have more implications later on.

Another is how shared the station is. The station effectively needs to share its bandwidth with everyone using it. When combined with the limited frequency window this means people might need to take turns transmitting (which needs to be controlled by the satellite). If the satellite has just a few people using it, it wont be that bad. But if loads of people use it then it can seriously slow down the data rate and cause more latency as its connection gets shared. (e.g. if there is a 100 Mb/s connection and a single person is using it, they get the full 100 Mb/s, but if 100 people are using it they each get 1 Mb/s).
This can be mitigated to some extent by using multiple satellites, but they are very expensive. It is much easier to deploy multiple ground based transceivers. That way they can handle a lot more people for the same area.

Another is cost. It costs a lot of money to put a satellite into orbit (and cost more to keep there or eventually replace). It is much cheaper to use more terrestrial options.

Another is signal strength/distance, which adds to complexity of setup.
With a terrestrial based system the signals only travel a few km for most setups. This requires minimal power and allows a unidirectional transceiver to be used on the end user's device.
For satellite internet it needs to travel hundreds to 10s of thousands of km. This requires satellite dishes. For a house based user using a geostationary satellite this is a relatively simple setup of installing the dish and having it point correctly. For either a mobile user or a non-geostationary satellite this requires a dish which tracks the satellite being used. If you want continuous internet from a non-geostationary satellite you would need 2 set-ups so one can pick up a new satellite before the currently used one goes over the horizon. Note that even in the simplest of cases, it still requires a fairly large setup (e.g. 1 m). Do you want to carry around such a big disk.
Also tied into the signal strength and frequency used is what is in the sky. Sufficiently dense cloud cover can block the signal, and the setup can't be inside as a roof would block the signal as well.


All of this combines to make satellite a very poor option for both the telecommunication companies and the end user.
It is much easier to have physical cables (even if it is fibre optic) and for wireless have wireless towers on the ground serving a relatively small area (e.g. a few square kms).
The time satellite is practical is for remote locations with few people where it is more economical to use a satellite to cover them (and other such areas) than set up all the infrastructure to get a wired connection to them (or a local tower); or when the end user will be moving and out of range of conventional wireless, such as at sea or flying in a plane.

So if you want to use satellite internet, go ahead, no one will stop you.
Just know it is likely to be much more expensive than normal internet and more temperamental.

Because so called satellites are actually land based  transmission station. The reason for the internet working on plane is still the ground station. The internet does not work on the ocean even if you are on the plane. therefore, planes prefer to stay in close contact with the ground station by entering close to land. otherwise they may disappear from the radar and fall. history is full of bitter experiences of this choice.

I’ve told this story before.
Back around 2002 I knew two kids who lived in the mountains. They were the nice homes but being in the mountains, they didn’t have good internet. We could inch multiplayer game at their place. They had satellite internet. One had both up and down and the other had download but upload was 56k.

You ain’t doing a ground based internet in the mountains. Even today cell service still sucks in the mountains.

Actually, this is all untrue to a degree. Internet does work on the ocean even if you are not near land. Sailors doing a 'crossing', in the case of the people I know, from N.America to the Fijian Islands have working Sat phones and Internet for storm/weather updates and emergencies. Data rates are very expensive. But they are at points thousands of miles from any land masses.

Planes tend to stay closer to landmasses due to ETOPS (Extended Operations) ratings and classifications. Most notably to be within X distance from diversion landing sites and said sites being able to handle a diversion/emergency landing. Quite simple really.

However, there have been instances when no amount of satellite or ground-based tracking/communications help in a given situation. Most notable of recent times MH370. The problem there, the transponder was shut off.

A Flight over the Antarctic Sea Ice From Chile to Australia (QF28)

[Nov 18 2016] For anyone interested, in a couple of hours I'll be heading out of Santiago heading for Sydney on the QF28. The flight plan has us spending quite a bit of time at 71'30" South and the cloud forecast at the moment shows not a lot of cloud! Lucky I brought 2 GoPros with me!

Fingers crossed for a good time lapse video of the ice pack!
The only land they flew near to on that flight was Antarctica and the pilot did get lots of photos of the ice-pack.

To follow on, these types of flights have a higher ETOPS rating/specification than normal long-haul flights precisely because they go beyond the bounds of normal diversion 'safe haven' landing sites. And those that do skirt environments like Antarctica have to carry special survival gear on board in case they need to ditch. All very practical and thoroughly thought through.

These flight never over-fly Antarctica so I think that the only requirement for a four-engined plane (747B here) is enough fuel to divert to an alternate airport and there are suitable New Zealand, Tahiti and South American airports.

The whole thread about that flight is worth reading: A Flight over the Antarctic Sea Ice From Chile to Australia (QF28).
It has a post about another flight:
Quote from: TWCobra
Note to a Flat Earth believer:
Abishua, I flew the QF28 flight from Santiago to Sydney a few days ago. I mean physically flew the aircraft, a 747.
We flew within sight of the Antarctic, down to 71.5 degrees south. We can go further south on that route but are limited to 71.5 south by lack of line of sight to the ATC communications satellites over the equator.

No, we've been through all this before, those ideas have been throughly demolished.

We know they aren't land based because the dishes don't point at them. There are no dishes north of the equator pointing north at their nearest ground station.

The internet does work on aircraft over the middle of the ocean. Internet does work on ships in the middle of the ocean. You can't tell such obvious lies, we know it's true, many of us have used the internet and satellite phones on aircraft in the middle of the ocean.

What do you mean by aircraft will fall if they aren't on radar? Why would wings stop working if you are out of range of radar? That would kill a lot of sea birds. Why would you make that up?

I know this might surprise you, but most pilots would see no reason to provide strong evidence to try and refute delusional people that think Earth is flat, who would just reject the evidence anyway.

There aren't cables and relay towers all over the place. With a satellite you can provide an expensive service to a few people, eg, a phone service for places where there is no phone service or you don't want to rely on the local infrastructure, or you can provide a cheap service to hundreds of millions of people, eg, satellite TV where its cheaper to have one satellite transmitting than to build thousands of TV transmitters.

And yes, geosynch satellites do have a smaller proportion of the traffic nowadays, most people live close to the cables and relay stations.

Also - "so called miles". You're not disputing the existence of 'miles' as well are you?

Do you have a proof, that "there's cables and relay towers all over the place on this very Earth"? Moreover, do you have a proof they were like 30-40 years ago, as first tv and GPS satellites were launched?

Could somebody show me any of this hidden relays? Because for today, it's easier to spot a satellite in the sky than to spot "secret" GPS ground transmitter.

In many aeroplane there is WIFI available for passenger wheret it is get internet directly from satellite. But why it is not available for us. Why using BTS tower that needs to dig up the ground for fiber optics connection to work.

Because so called satellites are actually land based  transmission station. The reason for the internet working on plane is still the ground station. The internet does not work on the ocean even if you are on the plane. therefore, planes prefer to stay in close contact with the ground station by entering close to land. otherwise they may disappear from the radar and fall. history is full of bitter experiences of this choice.
When I was in the Navy we had internet access on the ship out in the middle of the ocean from a satellite dish aimed at the sky. There were no land signals.

Why in the hell would anyone send a signal up into 23,000 so called miles into so called space to bounce it back from a so called satellite and back to Earth when there's cables and relay towers all over the place on this very Earth?
Airwaves and cable.

Space waves?..... ;D

There aren't cables and relay towers all over the place. With a satellite you can provide an expensive service to a few people, eg, a phone service for places where there is no phone service or you don't want to rely on the local infrastructure, or you can provide a cheap service to hundreds of millions of people, eg, satellite TV where its cheaper to have one satellite transmitting than to build thousands of TV transmitters.

And yes, geosynch satellites do have a smaller proportion of the traffic nowadays, most people live close to the cables and relay stations.

Also - "so called miles". You're not disputing the existence of 'miles' as well are you?
There's a very good reason why there's towers thousands of feet high.

And sky TV?
Because a slight nudge on a fixed wall dish knocks the signal to all hell. Maybe the ship is stationary on ice, right?
