what do you think about the radio frequency spectrum (although Satoshi in the white paper says BTC is an electronic payment system) it is only sending a few bytes through waves to be able to sign and verify transactions in that radio that in the end will be connected to the blockain network in some way that right now I don't know.
It's certainly doable and has been done before. Check out the following links for example:
https://www.shtfblog.com/how-to-send-bitcoin-over-ham-radio/
https://nitter.net/Coinsurenz/status/1052022462790033408

Probably the best way to do it would be to set up a mesh network via something like GoTenna (as the user in that Twitter link above did), with a person with an internet connection on the other end. Then you can cover a wider geographical area and anyone can send a transaction via the mesh network to the central point of internet access in order to be broadcast.

Note that you aren't sending data which needs to be "signed and verified" via radio, as you put it. Each user would sign the transaction they want to make locally on their own device, and would then send that signed transaction through the mesh network in order to reach the person who can broadcast it on their behalf.

Thank you very much I think I can do this it helps me a lot https://news.bitcoin.com/no-internet-no-problem-how-to-send-bitcoin-by-amateur-radio/ Everything I need to transfer successfully Bitcoin, or any cryptocurrency, is to know the public keys of the intended recipient. If I have that, I can use ham radio to send money. No internet needed! However, this technology is new and the process is somewhat complicated (there is not much information about it) but I think I can do it. Thanks super geniuses!

It all comes down to how can I transfer bitcoin payments to you without internet?
You can't. A transaction must be broadcast to the network via the internet in order to be verified and then mined in to a block.

That does not mean, however, that each individual needs internet access. You simply need some way of getting a transaction on to the internet. Each person can easily sign transactions on their offline devices, and then save those transactions as a small text file. All you need then is some way of getting those small text files to a person/node/service who will broadcast them for you. If you have a public WiFi spot in your community, then you can travel there and use that. If one person has a mobile device or similar with internet access, they could potentially set up a service broadcasting transactions on behalf of other people. There are services which allow you to send transactions via SMS as pointed out above. You could even transmit a transaction via phone call or radio to someone with an internet connection who could broadcast it on your behalf.

Since you are posting on this forum, you must have internet access somehow. Could you set up a method using whatever connection you are on now to broadcast transaction on behalf of your community?

Thanks for the information, you who are masters in this new technology, what do you think about the radio frequency spectrum (although Satoshi in the white paper says BTC is an electronic payment system) it is only sending a few bytes through waves to be able to sign and verify transactions in that radio that in the end will be connected to the blockain network in some way that right now I don't know.

Hello everyone, greetings and respect, I have just implemented a bitcoin BTC payment system in my small community with cold wallets but not all of them are young with internet access. Many of them have expressed their concern to me. It all comes down to how can I transfer bitcoin payments to you without internet?

I do not know if this possibility had been discussed before in this wonderful forum. But I need your help to see if all together we can achieve this.

I don't know, your contribution is supposed to be open source, but it seems more like a dodgy business or I don't know if you know what open source is.
