I recently found out about Thor Modes and now i am asking myself how it compares against LoRa. Thor seams to be possible on very low frequency, while LoRa is somewhere up at 800-900mhz.
How would a FM 4W CB-Radio @27mhz (full length antenna not a mobile device) in Thor Mode (Thor4 or Micro Thor) do against a commercial LoRa Module in a urban environment?
When you get skip on 11m, it usually goes halfway across the continent and nothing will be heard the next town over.
You need NVIS propagation to get a signal to a nearby location. That only works on lower frequencies like 30m through 160m depending on solar conditions. The signal gets send straight up and bounces back down in a several hundred mile radius around you. There is a map that shows which frequencies will currently work for NVIS as well as the Local Area Mobile Prediction tool to help you figure out what frequency to use for a given time and location.
Is a interesting topic, basically what i am looking for. Problem being is that right now i am restricted to license free bands.
