is it possible to send data over a phone call without dialup audio

I had a thought that is most likely not possible but wanted to ask anyways. is it possible with proper equipment to send an internet signal into one cell phone and transmit it to another via calling to allow the other phone(assumed is out of data range) and recieve data via an app that listens to the call for the data recieved and sends data back? I'm sure it would be slow but might allow you to Google something when you are roaming. my first thought of this would be a dongle that converts cat 5 to rg6, hard wire the rg6 into a phones hardware, and have the same thing on the recieving phone if for instance you lived where there was no internet and could plug a cat 6 into your phone from your PC.

I think you would be better off with a radio solution.

Look into amateur radio. There are people who have data connections working on VHF that can travel 20+ miles. There are also specialty WiFi kits that allow for long distance line of sight possibly up to a few miles.

Here in Antarctica we use a long range line of sight microwave shot for high speed data connections. Now, that might be out of your price range, but something on the amateur radio level would be affordable.
No, not quite the way that you want to do it. You can use your phone as a tether with a USB connection between the phone and computer if your phone supports tethering, which most do. Unless you have an unlimited plan, it will use up your data allowance pretty quickly though.
 

yeah I'm trying to figure out a way to get internet to an area where no data coverage or internet of any kind is available but full cell signal for talking is, so tethering would not be an option unfortunately. was hoping to piggy back the call connection somehow but I understand
 
If I understand this correctly, you want to use a cellular phone as if it were a land line and hook something like the audio output from a 56k modem to it to send data over the voice network to a phone that has no data connection because it is out of data range but has voice comms?

If I'm reading this right there are a few problems with that idea. First of which is connection based. A modem has to dial out and handshake with a receiving end. Which could be possible if there were a compatible modem on the other side, which I don't think there is an app for that, nor do I think a standard modem would even be capable of on the sending side.

The next issue is call quality. We are talking about a phone on the edge of service here... which have notoriously poor connections to even the voice network. Using something like modem tones requires a known solid connection, like you get across copper or fiber phone lines. This just wouldn't be stable over a cell network. You'd get data errors until the thing timed out.

The final issue is doing it outside of the audio range. Everything dealing with voice lines is made to work using the middle portion of the human hearing range. It cuts off high and low frequency sounds. This is why telephone modems as well as FAX machines sound so darn horrible if you pick up the line while they are working. They are trying to cram as much signal into a small notch of bandwidth as they can... which is also why modems topped out at 56k.

Now, this would be a really cool thing to try to engineer... buuuuuuut even if it worked the utility of it would be horribly limited.
 


I've also looked into that route as well but unfortunately sat internet is not available either.
 

yes you understand me correctly but instead of a dialup modem I was hopeing to use a modern signal that uses the 2 wire rg6 like what a modem receives. I only had the idea from when I installed directv I found that the rg6 to cat 6 adapter sends internet into the rg6 so that other sat boxes had internet connection. I found that with 2 of the adapters I can hook them together via long rg6 with one adapter coming from the router to another room and another adapter turning the rg6 back to cat 6 and plugging it into an Xbox instead of having a long cat6, because that's all the parts I had at the time to connect another room to a hard line network. that said I was hoping to use the same 2 wire signal across the network instead of an old dialup voice type signal.

that's an awesome idea and I will look into it, as for line of sight I would have to have a pole so tall it would be crazy because the height of the jungle, but I never thought about vhf
 


and about 15km down the road is high speed at a bar
