How to send data from an Arduino over LONG distances?

I was wondering how can we send data from an Arduino in real-time over long distances (such as a mile -- few miles). WiFi connection does not work for this, because it is mostly used for shorter distances.

How can I connect an Arduino wirelessly over long distances?

Thanks!

To what?

To me, a legitimate answer would be to use Arduino to switch a very bright light and send morse code which a human could read miles away. I have a feeling that won't work for you although it meets this spec completely:

how much data? how often? how fast? is it line of sight? for low traffic and low speed look at Lora https://www.lora-alliance.org/

I am talking about trasferring data between an Arduino and a computer over long distances (similar to a WiFi connection over short distances). I am looking to transfer data from various sensors over long distances to my computer...

I am looking to transfer data from various sensors (gas, temperature, color, etc) that will be placed on electricity lines and poles. The data is to be transferred to a computer, which is not in line of sight, at a distance of mile-few miles.

The time interval can be sending every minute, or every 30 seconds, something around that area.

if you have multiple sensor sites and do not require high bandwidth (e.g. transmission every 30 seconds or minute) you could look at a Lora peer-to-peer network arranged in a mesh http://www.softhard.io/lpwan-solutions/lora-peer-peer/ talking to a central node equiped with an internet connection to transmit data to your database

we are looking at similar systems for crop monitoring etc

Yes crop monitoring exactly that is very similar. Is there a way to transfer that data via a RADIO signal? I just feel that that could be simpler...

Lora uses radio but low power low data rate http://www.radio-electronics.com/info/wireless/lora/basics-tutorial.php

have a look at https://www.adafruit.com/product/3078

similar products are available on ebay for about £10

This is where you add some high gain antennas to your budget.

if you do a web search for Lora mesh you will get some interesting links, e.g.

it may be worth posting on The Things network forum

also look at Zigbee ??

The small LoRa tracker PCBs I sell can be used for remote battery powered sensors;

http://www.loratracker.uk/

Used as balloon trackers I have had them working at 270km on only 10mW, but thats at 1500bps, drop the data rate to 100bps and the distance should go up to circa 750km.
