Laser guided mesh network
https://www.extremetech.com/extreme/128207-1gbps-wireless-ne...
So facebook has backed away from attempts to make a internet service that uses solar powered drones to provide internet for rural areas that most
communication provided is weak or non existant.
So I build my own internet using old phones
But I need to transmit the signal farther then the provided Bluetooth and WiFi.
How it works the phone sends a message over WiFi the wifi signal is then sent over lazer on abandoned utility poles.
The receiver would be a solar panel that converts the lazer light to a electrical pulses that is converted to a connected peer to peer network
A router with a lazer in this case the phone turns into a router on the mesh network projecting the signal with a lazer attachment the the camera
picking up the light signals converting it into a connected network
A kind of lifi with lasers and Bluetooth connection
The phone just needing a laser attachment and the rest is software.
Free the internet

Freespace optical network ... wave bye bye to your internet every time it rains.

As if Silicon Valley understands anything about being "rural".
In the US, this is a political problem not a technical problem, and it won't be solved like this.

You are probably right along with other companies that are trying to do I know there are walkie talkies and CB radios have a far range if only they
could be used for carrying the mesh network farther I'm using serval mesh app works great for short distance I can even make calls without Internet so
I was thinking lasers reach far but how powerful would it need to be to reach 30 miles but I'll be good with just 1 mile too.
I have a couple of ballons with a WiFi range extender with its own power supply and app is set to direct Wi-Fi

I have built a laser detector that worked at 2km, though the data rate was fairly low. The laser was eye safe, so only a few 10's of milliwatts.
The whole thing is dependent on data rate, distance, beam divergence, optical interference (obstructions, weather).
Radio is easier - 1/2W of RF with a high gain antenna should go 30 miles easily. This is why ISPs do it using radio.

IF you have line of sight then you could consider a high gain wi-fi antenna
such as https://www.ebay.co.uk/itm/20dBi-Yagi-Antenna-RP-SMA-Male-Lo...
I've not tried, but in theory a pair of 20dBi antennas should give a usable signal at 2 miles,
and it would be a relatively cheap start/test.
If Wi-Fi seems feasible you could consider better antennas.
Google Cantenna - may work ?
There is probably a (not entirely legal) cheap booster/amplifier available for Wi-Fi signals.
Wi-Fi signals need short runs of low-loss cable.

Radio waves makes me think of the FM transmitter that let's me listen to music because don't have an axillary cable too bad they are low power
transmitters and don't broadcast far if electricity follows a laser wish radio waves would be carried on a laser to go further
But seems like I just need a directional radio transmitter and try to access the mini mobile network that I set up with my old phone connecting them
together. I find that if isplit a file and download them on wifi with each phone downloading a piece of the file then choosing one phone to combine
the files I think it was called jigsaw file splitter. In real areas we get internet via satalight and it is horribly slow compared to phone service
even though it is spotty and cuts off.
My friend lives 30 miles from me in the city and he has fast internet unfortunately he can not send it my way via tethering long distance.
