How do I send a PWM signal from a PC to an Arduino from over 50 km away

Hello,

I've seen the wireless options to communicate with an Arduino, however the range was always short, even using some antennas.

What I want to know is, if there is a possibility to send for example a waveform signal to an Arduino that is 50km far away. also receive a signal from the Arduino.

Thank you in advance

Shortband radio ? or over the internet ...

GSM?

Why send the waveform itself?
Wouldn't it be better to send the parameters for the Arduino to re-create the waveform ?
ALmost any wireless / celular or wired platform would work.

To actually send the waveform - perhaps by phone?

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

Can you tell us what the project is, why do you need to send a PWM signal so far?

A complete explanation of your project will help us give you a concise answer.

Thanks.. Tom... :slight_smile:

50km is over the horizon unless you are on an airplane or tall mountain. Most radios won't work through solid rock.

If there's WiFi coverage at both ends (connected to the internet) then use WiFi. If there is cellphone coverage, use GSM. If you aren't underground or indoors, use satellite.

I don't know what a waveform signal is and I bet you don't either.
